Quotebuilt350camaro Check to make sure the jumpers are correct under the stepper drivers on the ramps board. Good point! You could be off one pin right/left. Also, your RAMPS board came populated with an extra stepper driver. Before you swap drivers: Did you adjust the voltage on the steppers? The ceramic screwdriver will adjust the voltage to each stepper, if you tell the Z to move.. thenby Spam - Prusa i3 and variants
Devil, I had the same problem. I took an extra "L" bracket and put it about an inch from the inside edge on top, and it fixed my problem...by Spam - Prusa i3 and variants
QuoteMrfus Well, today after playing with the level on the bed and getting all correct, I tried to extrude some filament to check on the heating element, the steeper and understand about extruder test and calibration... After getting the temperature to 200 and centering the head so I could see the hot PLA coming I found that the steeper was moving but not pulling the filament, so I check againby Spam - Prusa i3 and variants
Once setup with the new firmware, I have had a lot of success... I even plugged in my display and it worked right out of the gate... But I think I am getting impatient... I was trying to print a large Pip Boy for a friend... The larger pieces are 7.5" long, and near the limits of the printer... After about 12 hours of printing, the darn thing shifted twice... on each part, at the same level...by Spam - Prusa i3 and variants
I gave up and reloaded the old software and found it had the same issue... So I know it's not the new version... I figured I screwed something up on the Repetier, so I uninstalled and reinstalled... loaded the new arduino code and went with the defaults... It's back to printing again! So now it's back to calibration. . . Thanks for the moral support!by Spam - Prusa i3 and variants

Did you adjust your stepper controller? Is it loud when you manually feed filament?by Spam - Prusa i3 and variants
Woo Hoo! It's alive! Anyway, lots of success after some trial, error, and some changes to the Configuration file... The instructions are a little light, but every problem I had was, for the most part, documented somewhere in this thread... Here's what I discovered: For those about to build, we salute you! Oh, these are in no particular order... 1. Read everything, read ahead, then build.by Spam - Prusa i3 and variants
I just got mine done this weekend,and I had a similar issue. I took an extra "L" bracket, and used it to keep the spool about 1" from the main frame, and another on the outside, leaving about 1/2" of play for the spool. With the filament fed through a supplied plastic loop (on the left Z motor as shown in the pictures) it worked fine. I can see where filament tension varies quite a bit, aby Spam - Prusa i3 and variants
It all worked out, and despite a few problems I feel this is a good DIY kit. The reason I bought a kit was to really understand the inner workings, and so far I am not disappointed... It definitely takes some work to setup these things properly, and these kits are not for the mechanically disinclined. The build is complete, tomorrow I power it on for the first time, and do all the electricaby Spam - Prusa i3 and variants
The part is definitely small, as the belt would not fit without modification, and the holes for the stepper motor are too close together by about 1/32" (1mm) One of the screws is even to short to grab, so I'm off to the hardware store to look for replacements. Overall, I am a little disappointed, but I cannot complain about the cost. These linear bearings keep the cost down, but they suck, soby Spam - Prusa i3 and variants
Got my kit last week and I'm in the midst of assembling this... been reading this thread for an hour now, but didn't find what I'm looking for, so I apologize if this has been asked: I am assembling the extruder carriage, and the bearings don't fit in the saddles. The instructions say press them in, but they're off by about .8mm. at this point I plan on grinding down one edge just a bit to geby Spam - Prusa i3 and variants
