the lead screw for the gantry has a slight bow to it and it causes it so bounce while in travel was curious to know if anyone knows where or how to go about getting another one
You can contact Langmuir Systems. They will sell parts for their machines.
I found that when assembling the bearing block on the end, that mine was slightly out of square, causing a bow in the lead screw. I realigned the plastic lead screw nut on the carriage by running it tight to the drive motor with it slightly loose, then retightened. Then I loosened the bearing block ran the carriage to the other end, and realigned the bearing block. It took the wobble out.
If bowed real bad, you can rotate in 1/16 increments, find the high side, and give a gentle push the opposite direction. Had to fine tune mine that way thanks to UPS.
