Recently moved and setting up my Longmill 30x30. Followed the directions for mounting to my wasteboard to the letter. Calibrated with G-Sender at 100mm and only off by 1mm. Machine jogs on the y-axis fine at precise and normal speeds but binds on the right side if I try to use rapid jog. Does the same when I run outline on a project. I have loosened the screws in the anti-backlash nut all the way to removing the screws altogether. The wheels are adjusted properly too.
Can anyone help me? The frustration level and blood pressure are thru the roof.
I’m setting up a LongMill MK2 48x30 that I purchased used and having issues with Y axis binding on the X axis as it moves in the rapid speed setting in both directions. I’ve checked to see if the X rails are square Y axis by checking the diagonals and the squaring program in GSender and the rails are square within 3 mm on both methods.
Thinking that it might be the lead screw blocks on the Y axis. I loosened the motor side of the couplings on both rails and moved the Y axis to the front legs retightened the couplings with no improvment.
Should I unbolt the lead screw nuts from the Y axis carriage and double check the carriage bearings for possible bearing failure. FYI, the bearings all moved smoothly with no slop or grinding detected when I reassembled the CNC.
