I just finished building my gMax printer (after getting it from the kickstarter a year ago), but am having some troubles calibrating it.
first: It seems my table is bent such that the X-axis edges are about 3mm lower than the center of the x-axis. The y-axis is level all the way across. Does anyone know how to fix this or will I need to get a new table? (If I need a new table, any ideas on a good, cheap replacement?).
Second: I was having issues with skipping and my layers becoming mis-aligned (sometimes by 1/4 inch or more). The calibration page suggested adjusting the potentiometer if skipping is heard, after some internet research describing under powered and overpowered motors I spent most of two nights trying to adjust the motor so it wouldn't skip. I now have run into a problem where the motor makes terrible noise it's receiving power at any point and pushing/pulling the table, even very gently, results in very loud "skipping" noises and the motor not working at all. Did I break the motor controller or the motor? I have been unsuccessful at getting my printer out of this state.
Thanks in advance for your help.
