Wheeeeeee, well maybe smiling bouncing smiley After I removed the belt the carriage slid back and forth nice and clean, no grabbing at all, and after a bit of probing I discovered that the idler pully was binding because I had the bolt that holds it in too tight and it had pulled the walls of the end piece in a bit. I guessing the ratio of the grabbing to smooth is roughtly the circumference of the pully. I loosened up the bolt and now the carriage dosen't grab, just the normal constant drag from the motor and the pulley. I crossed my fingers and ran a 2 hour print that I've been trying to do for a couple of weeks and I woke up this morning to a finished print with no offsets. smiling smiley

I wont be completely happy though until I get a chance to run a couple of more long prints to make sure it wasn't a fluke but I'm hopeful. It'll be nice to start a print and not wake up to a complete mess. grinning smiley

I thought I was there...

After replacing my mucked up stepper motor drivers, I finally got all of my motors working correctly. Everything seems to be moving good. I go my hot end to heat up no problemo. Getting sooo excited!!

... and then, I wasn't.

Problemo a. My bed seems extremely slow to heat. Originally, I only had the one(+12) and three (-) pins wired in, but everyone seemed to be saying to tie 1 (12V) & 2 (24V) together, which I have done; but it didn't seem to make any difference in performance - maybe even worse. I didn't do that wrong did I? Beyond about 66c it seems to be painfully slow to heat.

Numero b. The extruder refuses to extrude. On both Repetier and Pronterface I have tried to no avail. When my Z is up so I can see what is going on, I'll click on extrude, and nothing happens. You can see the ABS move up and down minutely at the entrance port, but it does not seem to want to proceed. I thought maybe it wasn't grabbing, and just needed some gentle persuasion. In doing so, there were times where it seemed to move forward, but then stopped again. Then I attempted a little less gentle persuasion (no hammer yet), and material was finally extruding, however, it seems to be completely under my own power. After a few attempts, changing from the included sample material to a reel of ABS I purchased, setting the extrude distance to 100 mm, and while it went chug chug chug, I added some force to the material on and off. No change. Also, just to be sure, I hit reverse to make sure I didn't have anything backwards, and while it still didn't move very far, it indeed felt like it was attempting to move it backwards - but like it wasn't grabbing the material.

As a final check, I swapped my extruder and Z motor drivers to make sure I didn't have ANOTHER bad one, and while Z worked fine, there was no change in extrusion.

I would LOVE some input into what I could be doing wrong, what settings might be buggered, or, worst case, what could be wrong with my extruder. It doesn't come across as plugged since I'm getting curlie cues under my own pressure, but it just doesn't seem to be gripping the material.

HELP! Please (and thank you).

I have my bed wired the same way and initially it heated up pretty quickly but over time it seems to take longer to get to the 110c I've been using for ABS. I saw somewhere on this forum that if you keep stressing the mosfet driving the port that it starts to heat up and cycle more so it takes longer to heat. I hung a 40mm fan onto the ramps board to help with the overheating and I'm back to a quicker heat up, still not as fast as originally but better.

As to the extruder unfortunately I'm not in a position to help since mine, KNOCK ON WOOD!!!!!, has worked pretty well right out of the box. If you read back in this thread you'll see where some people have had issues with it stopping extruding during a print to the point they took it apart and reworked it. I am finding out that on bigger prints unless I keep the fan going it will stop extruding, I'm guessing since both cura and repetier both keep the fan slowed down for the first couple layers the heat creeps up from the hot end and softens the filament at the drive end. I just had one print fail because it just stopped putting out plastic. When I cooled down the extruder and then brought it back up to 230c I had no problem getting plastic out. I haven't found out yet where to change this in the slicers so I just manually edited the gcode to keep the fan on all the time and the print is going on now so I wont know until tomorrow if it worked.

Do you have an LCD on the printer? I was having problems with Cura so it was real nice to be able to jog the extruder around manually and be able to test extruding and bed heat without a PC involved.

Would you share your changes to configuration.h that you made to support the LCD? I have the 4 line display on mine, but it only works when USB is powered on the Arduino. When the USB is detached, the LCD display turns off, and a green LED on the RAMPS flickers. I think this is a power supply issue, but I don't have any other problems than this.

Thanks!

Hello guys,
Finally got the package yesterday and immediately started assembling the printer. Then some issues started arising. One of the triangular acryllic parts came broken and the printed part under the bed that holds the belt was missing. I notified the seller and i am waiting for an answer. The problem is that I am in Greece and it will take ages for the parts to arrive. So I glued the acryllic bit and hope for it to hold until any replacement arrive, but for the printed part I am thinking of trying this:
WP_20141105_14_42_20_Pro by kgeorge1989, on Flickr

Do you think it will work? The nearest 3d printer that i know is 300km from me and it will take 15-20 dollars to print the part!

All I had to do is unremark one line in the marlin code to get mine working. I have the qraphical version and it's always on wether or not I have the usb plugged in when I have the power supply on. I recall seeing something on this board somewhere about your specific issue with only having the display when the usb is plugged in but I don't remember where.

I regret my earlier enthusiasm with an obvious anomally of a good big print, I tried to print a case for the electronics that had a fan in it and I had at least 80-90 percent of the bed covered with the top and bottom of the case and it blew up real good. I'll take a picture tonight and post it but it looked like, at 4 am in the morning so I could have missed something, that I had another X slip about halfway through so now I have what looked to be a good top, it was past finishing that piece, and half a bottom with a birds nest on top.

I think I might try and print out a new set of the X carriage parts, one at a time should work, and then completely replace it and the bearings and timing belt. At this point it's so random that I really do not have any clue what I can do to zero in on the problem. Figured I'd also replace the stepper driver with the spare while I'm at it as well.

It is getting kinda annoying, she flirts with me like she's going to put out then slaps me in the face and knees me in the groin for good measure eye popping smiley

I will have to get a fan for my RAMPs / Arduino boards it sounds like. As for my extruder fan, I have it wired into the power supply so it is always on. It sounded like some people had hooked it up where the power goes into the RAMPs board, but there were so many wires there, I just directed it to the other side of the printer.

I don't have an LCD setup yet. I was hoping to get it working first, but I'm around 3 weeks in with no joy yet. That's partly real life getting in the way, but I also keep hitting snags. I will try next to pull things apart and see if something is off. I keep trying to read through the forum, but after a few pages my eyes start to go blurry, so thanks for the tip.

Just a tip for contacting FolgerTech / SideWinderInc: do it through email / the form on their web page, not through eBay. I found their eBay response was slow and unpredictable, but from the website, it was helpful.

WPFLUM I have my fan set up the same way(directly to the power supply) So far the only 'problem' I had out of the box with my extruder was in the arduino code the extrude and retract was reversed(I took what they had on the google drive). Have you checked to see if is is making it through the extruder? There is a space between the black piece the motor connects to and the metal hotend. I know when I take my filament out and put it back in I have to make sure it goes through the hole for the hotend, sometimes it get hung up on it and hits the top of it.
Other than that I would check your vref for the motor, Almost sounds like it could be just moving back and forth rather than moving in a single direction, which is normally a vref or timing problem.
Re: Folger Prusa i3 Kit from ebay
November 05, 2014 12:38PM
The more I think of it the more I like it since the best practice for me seems to be to have both the extruder fan and the ramps fan on at all times.

I think you got me mixed up with NukedWorker as I've only had a couple of air print issues, probably related to the extruder fan being off, but he was having a problem with getting it to extrude at all. It does sound like a vref problem and not filament misallignment since he is able to manually push the filament through and get it to extrude, that or a wiring issue but I pretty sure he said he double checked both and swapped out the driver at least once.

To crudely put in in terms like I used earlier I think his isn't even flirting with him and has a chasty belt on to boot. winking smiley

/*================== Thermal Runaway Protection ==============================
This is a feature to protect your printer from burn up in flames if it has
a thermistor coming off place (this happened to a friend of mine recently and
motivated me writing this feature).

The issue: If a thermistor come off, it will read a lower temperature than actual.
The system will turn the heater on forever, burning up the filament and anything
else around.

After the temperature reaches the target for the first time, this feature will 
start measuring for how long the current temperature stays below the target 
minus _HYSTERESIS (set_temperature - THERMAL_RUNAWAY_PROTECTION_HYSTERESIS).

If it stays longer than _PERIOD, it means the thermistor temperature
cannot catch up with the target, so something *may be* wrong. Then, to be on the
safe side, the system will he halt.

Bear in mind the count down will just start AFTER the first time the 
thermistor temperature is over the target, so you will have no problem if
your extruder heater takes 2 minutes to hit the target on heating.

Granted it was a month ago but the only thing I remember doing to get mine working was to uncomment the line below and add the U8glib library. I had forgotten about the extra library until I saw it in the marlin code you posted.

//#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER


Now if we are talking about getting the printer itself working then yes I had to modify alot more lines. I didn't dig into the config file you posted so maybe it's obvious there but what screen are you using? Maybe because mine was the gui one there was less to change??

Do you have an LCD on the printer? I was having problems with Cura so it was real nice to be able to jog the extruder around manually and be able to test extruding and bed heat without a PC involved.

Would you share your changes to configuration.h that you made to support the LCD? I have the 4 line display on mine, but it only works when USB is powered on the Arduino. When the USB is detached, the LCD display turns off, and a green LED on the RAMPS flickers. I think this is a power supply issue, but I don't have any other problems than this.

Thanks!

I found the post I was thinking about reguarding the usb only problem.

[forums.reprap.org]

It looks like either a diode problem or a board problem, at least according to that post.

Many thanks - that's useful ... the symptoms are the same on mine. However, I have two RAMPS boards, both with D1 present, and the problem manifests on both. I'll have to dig around a bit more. First thing I'm going to check when I get home is whether with the USB disconnected I have 5 Volts on the LCD.

Has anyone tried adding an auto bed leveler to this printer? I picked up an activator from ebay for a buck or so and it finally showed up Monday, all I need is a microswitch and some printed parts to hold the bunch together. So as soon as I can get my X axis issue fixed, I'm thinking by Thanksgiving (notice I didn't include the year), I'd like to try and impliment the probe but in the mean time I figured I see if anyone else here has tried it.
Re: Folger Prusa i3 Kit from ebay
November 05, 2014 11:45PM
Here are some pictures of my latest failure. You can see how the X axis skipped and then started printing in mid air.

Also if you look at the upper right corner of pic3 you can see where the end stop must have gotten hooked by the rats nest of filament and either when the extruder got to the other end of the board or when I pulled it loose it bent the stop arm 90 degrees. I didn't see it initially and when I tried to push it back into place it broke off. Now I'm waiting for a couple of micro switches and some end stop spares to show up so I can try printing again.

Oh well that's life.......it kicks you in the nads, laughs while you writhe on the ground and all the time make jokes about your mother.....

Some days I really wish I drank drinking smiley

Let me know when you get the auto-level setup. I just got the J-Head, so once I get a few things printed I will be working on the servo arm. Something tells me I will have more issues than what I can imagine right now. But once its setup it should help eliminate the adjustment fine tuning.

Do you have an LCD on the printer? I was having problems with Cura so it was real nice to be able to jog the extruder around manually and be able to test extruding and bed heat without a PC involved.

Would you share your changes to configuration.h that you made to support the LCD? I have the 4 line display on mine, but it only works when USB is powered on the Arduino. When the USB is detached, the LCD display turns off, and a green LED on the RAMPS flickers. I think this is a power supply issue, but I don't have any other problems than this.

Thanks!

I found the post I was thinking about reguarding the usb only problem.

[forums.reprap.org]

It looks like either a diode problem or a board problem, at least according to that post.

Many thanks - that's useful ... the symptoms are the same on mine. However, I have two RAMPS boards, both with D1 present, and the problem manifests on both. I'll have to dig around a bit more. First thing I'm going to check when I get home is whether with the USB disconnected I have 5 Volts on the LCD.

OK, this is indeed a 5V power supply issue. When the USB is plugged in, it supplies 5V to the LCD. When it is unplugged, the Arduino's regulator is supposed to supply 5V from the 12V main supply. But on my board it doesn't. This may be because the Arduino's regulator is kaput.

So, I will use a 7805 to provide a separate 5V from the 12V in ... this is simple enough to do.

A 7805 is not very efficient and will generate a lot of heat, there may be better options that wont generate as much heat,
or that may be more efficient... smiling smiley it's a good stop gap measure, but as a permanent install you may wish to get something more efficient,
and cooler running smiling smiley

See National LM2575 datasheet for details AND Calculations

Thanks - I'll check out the LM2575. I have lots of 7805s handy, so will go with one of those for the time being.

I remembered reading somewhere that putting the endstop headers on backwards could blow the regulator I'm not sure is relevant anymore as the post was from last year. Could that have happened to your board?

It's possible, although I was quite careful about polarity when wiring up. I have another Arduino Mega that I can swap in, to confirm that it is indeed the Mega's regulator that is the problem.

I'd just wire up the power to it and see if it's power up the LCD so that nothing else gets in the way since all you need to do is see if it works on the power supply.

Ok, so my printer is shipping today or tomorrow (I have a UPS tracking number but it doesn't seem to be picked up yet) and it's expected to be here Monday. I can't wait to get it and do an unboxing video and get ready to build it. Looks like I won't be sleeping at all next week. I'll keep you all posted.

Ok, so I had some time over a few days to get the extruder apart. Interesting to watch it fail in action...

Video to my patience test

So when I noticed it seemed to catch on the set screw, I set out to turn it around, and for the second time, had to go shopping for a hex driver (1/16) that wasn't in my collection (the last time it was 1.5 mm). Don't get me wrong, I like tools, but sheesh (this time I got a monster set, regular $28, on for $13 at Canadian Tire). Unfortunately it didn't seem to be enough. As soon as I introduce the filament, it still does a jig back and forth.

With it open to reduce any added friction, I played with the v-ref a little, ranging from 0.35v all the way up to 0.5v. With no change (so I went back to 0.35v as it seemed to be the most valid based on other people's posts). I will try again when I've chilled a bit (I might just be bleary eyed). Is this a fair assessment for my v-ref?

Could it be something in my code?

Also, I'm wondering if I might have to drill out the channel a little as it seems a bit tight. I know some people have had to make some alterations to different parts of their kits. Has anyone had to go this far yet?

Thanks again for the input.

Wpflum. Are you printing from SD or USB when your failures occur?

I typically print from SD but I do recall seeing a similar jump back when I was using repetier host over USB if the PC got bogged down. Almost like it skipped a few lines of gcode. That only happened a few times though. Was not curious enough to try to track down the issue with a sniffer or anything at the time.

Have you used any lubricant on you X axis? Having played Trombone for several years I happened to have some slide oil that worked well on my setup.

Another thing to consider is your wires or even the belt tensioner getting caught somewhere. Any zip ties On wires potentially rubbing edges somewhere even if only sometimes?

You might try forcing some rapid movements while not running a print in order to try to find what brings the problem out. If you can make it repeatable in front of you it should help find the problem.
Try jogging back and forth 100mm at various speeds to see if any of them cause a problem.

I normally print from the SD. I'm trying to remember if one of the previous prints that failed was from the usb, I'm not sure if I had any but the last one was SD based.

I don't have anything on the smooth rod to lubricate, I kinda assumed that since I was using a ball bearinged slide that I didn't need any, would dry graphite work? I have some from a number of years doing pinewood derby.

The wiring doesn't seem to be the issue but I'll double check that again. I'm not using belt tensioners so there is nothing to hit there, I am still partial to something with the idler pulley but it was working smoothly after I did the last adjustment.

Forcing high speed changes isn't a bad idea and I'll try it over the weekend, unfortunately since I broke the end stop and wont see a spare until monday I'm kinda on hold for much testing.

I agree the pulley seems like a likely culprit still based on what you have said. If it isn't too tight there may be something going on with the bearing there or the plastic parts that press together. If I remember correctly that is the same parts as for the Y axis. If there isn't anything obvious when you take it apart you might try switching the two of them to see if the problem follows.

As far as lubrication goes. Take a look here

Good luck with your testing.

Not sure if I answered your questions:

Yup it's ABS, and my printer is in a 11' x 14' bedroom and if the printer has been printing for an hour or so, yes the room does smell like burned plastic (ABS smell). It's not terrible, my wife has not compained about it, and thats a pretty good barometer ... smiling smiley I purchased the filament from www.filaments.ca it's good quality stuff... ( I order PLA from there as well for the Makerbot Replicator 2, the PLA is great as well, nice colours and always great prints.. )

at any rate I have attached my slicer bundle setting file and my configuration.h file,
please note, my Y end stop is at the front of my printer, and my x stop is on the right...
that may make a difference...

when I print, my objects face backwards, but as far as I know they are not mirrored...
so my x=0 and y=0 is at the back right corner of my printer smiling smiley

Waltermixx, if you do manage a way to export your settings, I think it would be great to benchmark to fine tune my settings. Your prints seem to be problem free! I notice you are using ABS, where did you order your filament from? Any smell associated with the filament you are using?

And for those of you messing around with the hot end, do not over tighten it....See below for what can happen. (Had a bit too much hear and a little too much force when installing the threaded portion, the heat throat snapped like a piece of spaghetti.

Anyone have any experience with Folger's all metal hot end? Seems really cheap compared to the others? Also looking into the prometheus hot end as it is local and I could get up and running sooner.

where did you get your J-Head from? you mentioned locally? got a link? will it mount to the x-carriage spec'd for this printer? (30mm hole spacing) smiling smiley or will you have to use another x-carriage with it... do post pictures... smiling smiley
