I braved printing ABS, ran up the bed to 105C, started printing and about 15 minutes in all 3 steppers gave out. Does anyone experience overheating RAMPs, while cranking up the heat bed. I have ran one hour PLA prints with no issue. The stepper motors are moderately warm at about 45C.
It looks like the bottom bed insulation and controll board relocation is a must on these machines.

Ok - my feeble brain has been at this all day. I feel I'm on the right track but can't seem to get my brain wrapped fully around the smooth rod offset value to level the effector. I went through the link for adjusting in a previous post, I am at z-pos 0 at center, but around 2.1mm on each tower.
So at least they're all pretty close on the towers, so this tells me that the effector is going away from the build plate as it moves to the tower? So if I adjust the end stops that would not help I am thinking because that would mess up the center z position. I read that I should adjust he smooth rod offset in smaller .5 increments. Am I on the right track?
Thanks
You are compensating for the concave/convex curve of the heatbed. Get the 3 tower positions zeroed as close together as possible, the check the z-pos in the center. Adjust smooth rod offset, check the 3 tower positions again. Get them zeroed (again), then check the z-pos in the center (again). Repeat all this as much as needed or until you have pulled all your hair out. BTW, you do want the nozzle and heatbed at working temps when you do this.

No not really, not until you have the effector moving flat over the surface.
When you have the effector moving flat across the bed it is easy to just adjust "MANUAL_Z_HOME_POS" to compensate for the heat expansion.
EDIT. I haven't tried for my self but from what I understand you can use a factor of 2.2 to get close faster than just adjust .5 increments.
Say you have all your endstops at z=0 and the effector at the middle stops at Z=2.30 then you take 2.30*2.2 and subtract that from your present radius (DELTA_SMOOTH_ROD_OFFSET).

With electronics under a heated bed, an electronics cooling fan and appropriate ventilation holes are essential IMO.

Ok, i have all 0's on my towers, and a -2.8 on my center. changed man_z_home_pos to 0 the center just to see, and i get the following:
Before:
A: 0
B: 0
C: 0
Center: -2.8
After:
A: 1.8
B: 1.2
C: 2.2
Center: 0
Should i take a step back to the "Before"? and your example shows a positive number on the center when towers are 0'd.... what should i do for a neg?

No difference, you do the same for a negative value: DELTA_SMOOTH_ROD_OFFSET - 2.2*(-2.8) = New DELTA_SMOOTH_ROD_OFFSET (this will actually add to the DELTA_SMOOTH_ROD_OFFSET as two negatives becomes positive)
However the 2.2 value is based on that your rods are absolute vertical at the tower positions, which they most likely are not, so the last finetuning will be more of a shot in the dark, that's when the small changes come in, where you should start to increase/decrease by 0.5 and as you get closer by smaller numbers.
It is a bit odd that your values at the towers became different amongst themselves when you changed the homing position, but don't dwell on that you are going to have to redo them several times anyway.
Just adjust your endstop so that all is at z=0 and then measure the middle, calculate and alter DELTA_SMOOTH_ROD_OFFSET, flash and redo all again until you get a absolutely flat movement.

Eeee......extruder, not hot end. Other end of the bowden tube you know..
Thanks anyways
Doh!! i was reading that after waking up and didn't have a full cup of coffee in me. Yes! The extruder in this is junk, I think Tim pointed out a while ago it was designed to be on the hotend and pulling, versus pushing. I reworked this one a little and it works perfect for the job.
+1 On this rework. I downloaded and printed this design and works 10x better than the old extruder used to. Havent had any issues with it and prints are getting dialed in for sure. Between this and the dual fans on the hot end, everything is printing nice including overhangs which is what I was having issues with.
..................
Print cooling is also high on the improvement list, I can only spot one fan on you pic cman8.
Cheers!
Yeah on that pic I hadnt installed the dual fan mount. triple actually. I used this mount which works awesome. note it will eliminate your auto level so if you use it then this design wont work. But thanks to the help here, I got my printer level and dialed pretty well in so I just manually check it every once in a while to make sure its still good.

Probably seen it already but I followed this guide and is what got me on the right path. Thanks to everyone here and this you should be golden.

Holy crap, i owe you a couple beers.
that worked GREAT!!! did the 2.2, and that brought everything really close to the center point of -2.3. adjusted the end stops to 0 and i was off on center about -.1 adjusted my center point and it's working great!!! thank you so much!!!

Hello, I'm new to this forum and I'm looking to build my first DIY printer. The Folger Tech Kossel Delta 2020 seems to be one of the better deals for the price. Im wondering if anyone can answer a question or two before I buy it. Can you tell me what the differances are between rev a and rev b and have the instructions been updated to the latest model? Also are there any parts I should buy and use instead of the parts that come with the printer? I have read about people using different parts or adding fans to the motors ect ect. I figure I would ask about this and buy different parts if it is worth it to replace them. How does the software work with windows 10 and has anyone had any issues? Is it worth getting a LCD screen or should I just get use to this basic printer first and add the LCD screen later? Also where do you guys buy your filaments from and are some better then others?
I know I asked a bunch of questions and thank you for any advise you can offer.
Thanks
Dave

Rev A contains printed parts, linear rails, servos and mechanical switches.
Rev B contains metal and printed parts, wheels on the uprights and inductive sensors.
If you know where to look/buy you can buy all of the parts for the printer from various locations for roughly 75-100$ less then you would pay for this printer. You have the hassle of dealing with multiple vendors however. No issues with Windows 10 on the software; although, you may need to reinstall your Arduino software if you upgraded from 7/8. I had to reinstall just a few drivers for the system. As for filament, I buy mine on eBay or from Microcenter. I pay between 17-24$ for my filament depending on color. Some is better then others, I like the filament from this seller and have burned through a couple of rolls without issue.

I got a couple of fans for cooling plastic and electronics, a spare thermistor (to check temperatures), and some cork to insulate the heat bed and motors. Oh, and a mk8 extruder pulley, you print the rest of the extruder once the printer is up and running. Most the parts you will want to have for upgrades you can print. You are going from buyer to maker now.

Sigh, the replacement Duet that Replikeo sent me failed so I ordered another one. That just arrived today and is also DOA, I am beginning to think the Duet is an overpriced and over hyped piece of junk. Good thing I also have a Due/Ramps-FD board sitting here. I will ask Replikeo to replace this one, but I am not holding my breath.

What failed? Mine from them is working (so far). The USB connector came completely soldered.
Still in the process of swapping it in to replace the Arduino/RAMPS, but it is going very smoothly. Got the differential IR sensor, and it is slick I've been amazed how easy it is to configure the Duet with the dc42 firmware.

First one was the USB falling off, second I might have had a hand in so I am cutting it some slack on that one. It was working fine and then just died and the chip started getting hot when plugged in only via USB. The third one won't respond via USB on my laptop, desktop or Mac. I checked out the USB connector under a loop and it looks connected properly. It powers on and the network card even shows a connection. However, it won't respond via IP and I have verified the card contents and swapped to different cards as well. I also attempted to power up the unit off the supplied power module with no luck.

No, since I can't get the machine to see the device it won't present a port for it to access. I am wiring up a JTAG header now to see if I can access the chip via that method. I connected the Due to the same port and it detected without an issue.

Thanks everyone for the advice. Slowfoot, Did you see a need for the fans for cooling, cork and the mk8 extruder? Do you think those things offer extra protection or are better quality parts?
Is it worth me adding an LCD display or should I just add one later if I find it nessary?

Yes, you will definitely need cooling fans on the motors or you will melt the corners. The cork assists in keeping the temperature in the bed and not on your electronics. It would be a good idea to replace the extruder as well, maybe as the first print.

Oh, and a mk8 extruder pulley, you print the rest of the extruder once the printer is up and running. Most the parts you will want to have for upgrades you can print. You are going from buyer to maker now.
Cheers!
Thanks everyone for the advice. Slowfoot, Did you see a need for the fans for cooling, cork and the mk8 extruder? Do you think those things offer extra protection or are better quality parts?
Is it worth me adding an LCD display or should I just add one later if I find it nessary?
Yes, you will definitely need cooling fans on the motors or you will melt the corners. The cork assists in keeping the temperature in the bed and not on your electronics. It would be a good idea to replace the extruder as well, maybe as the first print.
Thanks again for the advice. Do you have links or parts numbers of the parts you bought? And is it easy to hook the fans up for a beginer like myself? Also I have read that this printer produces good prints but I cant fine specs on what the printing resolution is, Do you know the specs on this printer? Also it looks like the REV B printer have metal corners, is this true or is the picture on the web site not accurate?

Thevisad, have you outfited your kossel with a proximity sensor for leveling?
Yeah I have an inductive sensor I am throwing on the printer. I will be wiring up the hotend tonight as it finally arrived.
Any advice on how to hook one up? Is it fairly straight forward?

got these going recently - they came untapped. I looked in the RevB instructions and they suggest using a screw and a nut on the inside. I thought that i would just get a 4mm tap and some screws and it turned out nice and stable!

I got my stuff from RepRapMe together with some cheep PLA. They are located in Denmark so there might be more convenient sources if you are located outside the EU. The fans for motors and electronics can run directly from the power supply.
The the cooling for the plastic can be controlled by the electronics and the G-code, The printer will work without it so you can add it later, you have to print some parts for it anyhow. It will improve print quality. The kits extruder is not the best for the task and replacing it is an easy improvement. You will not be the first doing all this so I think you can make it.

.................
Yeah on that pic I hadnt installed the dual fan mount. triple actually. I used this mount which works awesome. note it will eliminate your auto level so if you use it then this design wont work. But thanks to the help here, I got my printer level and dialed pretty well in so I just manually check it every once in a while to make sure its still good.
Thanks !
