Still trying unsuccessfully to get my Rostock MAX calibrated so I can use it to it's fullest extent. I'm still having issues with getting the bed fully level. I have adjusted the endstops countless times, and have finally calibrated the printer_radius setting to adjust for the slight concave motion on the bed. Now I'm having an issue in which my print head raises 1+mm away from the bed on the left side of the Z rail, and to the right of the Z rail closer to the Y rail, the print head jams into the bed
Per 626Pilot's suggestion I have read this post over and over viewtopic.php?f=54&t=2765&start=20#p23853
But I'm confused on this part:
If you find that the carriage lifts or dips close to one tower and does the opposite next to one of its neighbors, it's probably the rotation on the remaining tower. Look for Alpha A, B, and C in the EEPROM. You will see the values 210, 330, and 90. Reducing a number rotates the tower clockwise and increasing it rotates the tower counter-clockwise. You should only need to change the rotation by 1/2 to one degree. This is where you have to think of terms of pushing and pulling. On my printer, it was lifting near the X tower and dipping near Z. Y was OK, so I assumed it was the culprit. Changing Y's rotation from 330 to 331 fixed the problem, because that gave Repetier a better idea of where it was starting from. It then knew to move the Y tower a little faster when going towards X, and a little slower going towards Z.
Forgive me but I'm completely stumped as to what he's saying and how to apply it to my situation. I seriously believe I need a very minor tweak to one of these numbers, but which one?? And what letter corresponds to what rail? Is Alpha A the X, Alpha B the Y and Alpha C the Z rail?? So confused, any help would be GREAT!!!
