If you have a ramps board, see here http://reprap.org/wiki/Pololu_stepper_driver_board It is possible that your motor current is too low, or, indeed the speed or acceleration too high.by msmone - General Mendel Topics
Thanks edn, for helping me with the software. Everything works now on my Makerfarm Prusa i3 8" For anybody who can use it. I attached some files with the changes i made to get the autolevel to work. Tested it a few times with the bed 3mm unlevelled, works just fine. I have a little distortion on the servo, even with the 5V supply from the ATX attached to the 5V on the Ramps. But when you set tby msmone - General Mendel Topics
Quoteregpye Check out this part that is further up in this forum. There is a problem in the code for the feedrates when moving for bed leveling. #define XY_TRAVEL_SPEED 6000 // X and Y axis travel speed between probes, in mm/min This is not only used for XY travel but also for Z travel. That is the reason the Z motor stall. I fixed some things in the code so that the Z moves uses the homingby msmone - General Mendel Topics
Hi, I had the same problem. I use aceton mix with abs to put on the heat bed just before printing. This helped a little. What helped more was this: . After this no warping problems anymore. Also no jams of ABS since then.by msmone - General Mendel Topics
If put temporary some insulation on the bed, it will reach much faster the wanted temperature. I also want to try to put some radiator insulation foil below the bed, i think this will speed it up even more. And save energy...by msmone - General Mendel Topics
Hi, i´m also new to the 3d printer bussiness. I build a makerfarm prusa i3 since last week. But i think i have an answer for the shifting layer problem, or motors that did not move enough. You solved it by lowering the acceleration, that is one way. But i think the problem is that you have to increase the current to that particular motor. Just a little bit. By lowering the acceleration, you needby msmone - Reprappers
