I just retired my old techzone electronics and upgraded to Ramps 1.3 with RepSnapper.
I am trying to do calibration and test prints, but I keep running into the same problem again and again, the machine glitches and stops after a few minutes of printing. It will do the first layer and then somewhere in the second layer it hangs up and freezes, but not in the same place each time. I have repeated the glitch 5 times now with 2 different gcode files. Nothing feels like it is overheating, and I even put a fan on the Ramps board just in case but it keeps happening.
when you say in the same place with 2 different files, do you mean the same line? I am having a similar problem with Repsnapper and gen 3 electronics. No matter what combination of G-Code, firmware version etc.. it seems to fail at line 1446. I played with the temp refresh rate as well as the buffer value in the repsnapper preferences but to no avail.
