I'm having some problems with my Y axis, the print jumps back a bit (here's a video [youtu.be] ) it makes a thudding/clicking noise. My stepper drivers seem cool and not overheating when I touch them and the motor itself is cool too. I've retightened all my set screws and everything and the belt is tight. I'm out of ideas, any help?
Is the print skipping steps? Sure sounds like the belt is slipping/jumping. I had that happen once when I tried a belt tensioner and made the belt pretty tight.

I think I've asked this before, but is anyone running Repetier Firmware on these printers?
Yes, I changed from marlin to repetier a couple of months ago. So far it has mostly worked to my liking, accept that it only offer the three point method for auto bed leveling.
Mach,
Very Cool...I'm running a E3D Cyclops and they recommend using Repetier Firmware as it supports the dual extruders single nozzle setup and also allows extruder mixing (something I'd like to try) so I'm curios!?!?
How hard was it to set up, did you basically run the Configuration Tool and upload the file through Adruino to get it going...dare I believe it could be that simple!?!? If I try it and it doesn't work can I simply reload my old Marlin Firmware and be back were I left off? I'm not afraid to try it, I just want to make sure I can get back where I was if I need too!?!? If I go this route would be okay to pick your brain if need be??
Thanks,
Sonny
For the most part, yes it is as easy as using the config tool. Some of the options that I selected did not get put into the config.h file, so I had to do it manually, but otherwise it was mostly pretty simple. One things that was a big pain in the rear was a safety feature that prevents decoupling accidents with the bed. It kept on triggering even though nothing was decoupled, but that may have been my thermistor's fault. Yes, you can revert back to your old firmware if it does not work out. I could even provide you with my config to get you started if you would like.
Mach,
I'd like to give it a try so having a copy of your config-h would be great!! What setup are you using for Auto Leveling...servo/micro or Proximity? I have both but not sure which I want to use yet.
Thanks again,
Sonny
I am not actually using the autobed leveling feature, just using a inductive sensor for the Z endstop. I have it enabled and configured in firmware so that all I need to do is add the g29 command and it is set. I would suggest using the proximity sensor.
Config file attached. You may want to look through it first since some of my temperature settings may be abit bizarre.
I'll take a look before I upload it, and will go with the proximity sensor. If needed would you suggest making changes in Arduino, a text editor or use the configuration tool?
Thanks again,
Sonny

Sorry, really untimely reply by me. Pm sent. Also, I would say arduino is the best way to go for editting it.

You might read that the DRV8825 steppers run at 1/32 resolution, whereas our stock steppers (A4988) run at a lowly 1/16 resolution. You might say to yourself, "hey, a set of them are only $15 on Amazon, and they might improve the print quality since the stepper position will be 50% more accurate".
For us, they don't. After installing them and having to turn the pots almost all the way up to get any sort of reliable motion, I learned they are meant for 24V setups, which is not what we have. I pulled them and reinstalled the A4988's and all was well in the 3d printing world again.
DRV8825's are like meth. Not even once.

Hello Forum!
I'm new to the 3D printing scene and just finished the build of my FT 2020 last week. Once I "finished" the build I went over all the electrical connections to be sure they were all correct at least twice prior to ever plugging the unit into the USB or wall outlet. All the connections as listed in the build manual are correct. The configuration given by FT on the Google site was downloaded and I thought this was easy. I will be printing in a couple hours. So I go to home the unit. That's when things go bad. The home position is supposed to be where the extruder tip is located in the back right corner o f the bed. The X and Z axis seem to move to the correct positions however my Y axis is opposite they way it is supposed to move. During some iterations I also found that the Z axis is only responsive when it wants to be??? I ran M119 command and found that Y Max and Z Max are triggered all the time, even if the end stops are unplugged.
To make matters worse whatever is causing this issue also made my arduino smoke. Some forums suggest it is the voltage regulator as it seems to still work from USB.
I have tried the FT support site 4 days ago but have not heard anything from them. I believe the Ramps board may be defective but want to get some suggestions before replacing it.

So I introduced myself just a few days ago saying I'm waiting for my printer to come in. After extensive reading and the last post showing it is NOT a fixed issue, it seems the Ramps board are just crap. Would I be better off just ordering a new one straight out and not chancing anything with the one from FT?

G28 question.
Can I change the Z-probe location on the build bed when running G28? Currently it is Z-probing in the center of the bed, I'd like to have it probe for Z- 0.0 at X-0.0 Y-200.0...is that possible!?!? I've search the interwebs the last couple days with no luck...
Thanks,
Sonny

Those settings can be changed in the start gcode of your slicer or host.

Uncertainty
For those of you who have x&y belt tensioners, what do you use?
For my X-axis I use [www.thingiverse.com]
I need something for my Y-axis. I found this [www.thingiverse.com], but I do not like the design.
Also, without changing the Z-threaded rods, what would you all recommend for reducing backlash? I was thinking of replacing the nut with a long nut...

According to the instruction manual, The plug for the X motor should have the red wire to the left. Put it just like the picture shows. The instructions call this the 'Z' motor again. Also these things need to be done that are different from the instructions.>>
Change the following in configuration.h
#define INVERT_X_DIR true to #define INVERT_X_DIR false
#define X_HOME_DIR -1 to #define X_HOME_DIR 1
With the printer off PHYSICALLY move the x-axis stopper to the left one set of pins (this makes it so it's the x max instead of x-min)
Now if you are using rep host, you need to go to printer settings > printer shape and change home X: from min to Max.
One big glaring mistake in the build manual is putting the X stop plug in the wrong place on the board. It should be right next to the Y stop plug, not two over as the manual says. Also, for the X motor plug wires, keep them as you see. It's not a mistake to have them reversed from the others. I DID end up reversing the extruder motor plug because it was pushing the filament out the top!
The new spring design extruder has a brass feed gear that, for me, was rubbing inside the motor housing and causing it to drag and skip steps

In your attempts to getting the printer working, you probably have changed some other settings in the files. I suggest that you reload the Folger Tech files again and then make JUST the changes outlined above.

You can fix this in the configure file by enabling the max end stop pull-up resistors or disabling the max end stops altogether.Quote

I did these things last evening and now all the travels seem to work in the correct direction. However, I still am getting a YMAX and ZMAX triggered at all times. Currently if I try to home my Y axis the bed moves to the front of the machine and doesn't stop it just wants to keep going and grinds on the belt. The Z axis will home to the endstop but will be locked there - as in I cannot even manually move it away from the endstop.

What aluminum print bed are folks using with an inductive sensor? Is there an aluminum surface that can be added to the top of the MK2B heat bed (instead of the glass), or are people replacing the heat bed altogether? I'm going to add the proximity sensor. Tired of constantly adjusting my print bed alignment...
I just use a 8x8 inch aluminum plate I got for 13 bucks. This one
That looks pretty good! Does it stay fairly rigid and flat? Also, any problems getting the MK2B heat bed to keep it above 100 deg for ABS?
The plate is about 3mm thick so it has almost no flex to it. The plate I received was not entirely flat on one side, but the unevenness is within fractions of a mm. I just turn the plate onto the side that had the least curve after putting on the binder clips and it works very well. I only print with pla right now, so I have not tried going to 80c.
Thanks Mach!
Anyone else placing a 3mm aluminum plate on top of their MK2B heatbed? Any issues staying above 100 degC? I think I'm going to jump on it unless anyone has an alternative.
I had the 3mm aluminum bed over my MK2B heater, I never got it over 85C...I ran PID and it heated more quickly but still struggled to go past 85C. Could be something in my setup that's wrong...I'm not sure. Either way I printed ABS at 85C with no problem...I do print on Kapton though...
I might be going back to glass and a different sensor, if so I'll have this Build Plate and two sensors up for grabs...

Hi All, also waiting to build my FT2020 i3 (so probably a lot more questions to come after xmas - sorry!) I've already posted something similar on Reddit but have a few more things I'd like to get clarified and this place seems more active.
Marlin:
1. I was planning on using therippa's Marlin from the start and skipping the FT version completely. Is this advised? (I'm assuming 'Yes!')
2. If I move the X-Endstop to the left (MIN) side of the printer as seems to be the advice, does therippa's Marlin already account for this? I've looked in the 'ENDSTOP SETTINGS' in '@section homing' in config.h and they are all set to -1 (MIN). Is this the correct section to check?
3. In '@section temperature' I noticed that TEMP_SENSOR_BED is set to 0. Does this need to be changed if using a heated bed?
4. I will be installing a 128x64 LCD when building the printer. Is this already enabled? I've looked through '@section lcd' and nothing seems to be enabled..... Is DOGLCD the correct one?
Electronics:
5. Is it possible to test the RAMPS before installation? I know I can test the Arduino by uploading the blink sketch but wanted to test the RAMPS without connecting up the PSU, Steppers, Drivers, etc. If it'd be easier just to wire up all the electronics to test (i.e. before they are installed during the build) then I'm happy to do that if I have to.
That's it for now thanks!

1. Yes!
2. No, there are a couple settings you have to change, look at my personal settings (https://github.com/therippa/Marlin/blob/E3D_V6/Marlin/Configuration.h) from the top of my head you have to change X_HOME_DIR to -1 and set X endstop position to MIN in your host software (which it should already be by default)
3. ...what file are you looking at? TEMP_SENSOR_BED is set to 1 in my file (line 110)
4. Look to my personal settings branch for the settings to enable that LCD (line 569, and you have to load u8glib, google it)

Just to check - the version I've downloaded is the release branch (https://github.com/therippa/Marlin/tree/Release/) > 'Download ZIP'. This is the one I was planning on using.
And I should IGNORE this advice from your page: "Changes you must make to the RAMPS board and Host This firmware corrects some problems with the Folgertech firmware, namely X-axis issues. Please move your X-endstop plug one set of pins over to position 6, and change the X-Endstop settings in your host to MAX."
Cheers
