[SOLUTION?]
In the midst of troubleshooting the motor to convince the mfg to replace it, I tested the expansion kit’s motor to seenif it had any issues and it worked fine. Got the bright idea to just swap the motors for now and figure out how to replace the bsd motor later. In removing the y acis motor from the gantry I somehow loosened SOMETHING that was too tight and now it seems to be moving correctly. Possibly something was too tight in initial assembly and rebuilding that section did the job. We shall see over time.
[OP]
So, long story INCREDIBLY short… the x axis came pre-assembled and once I got everything together, it would not slide. When the belts for the x axis are off, or loose, the carriage slides freely. Once the belts are secured, it’s locked in place. Decided to connect it and configure it to meerk40t to test the motor itself.
[Was able to configure it in 0.9.2 alongside my S9 machine, copy the folder, make a 2nd script to launch separately and run 2 instances of meerkat at the same time with each cutter working independent from the other]
Upon trying to move the x axis via meerk40t, I get a grinding noise and I can see it trying to move, but nothing happens. Youtube was a dead end as far as my choice of keywords as well as google. If someone could link me to something that explains how the x axis it assembled or actually troubleshoots this problem, that would be great. Otherwise, I assume the motor is bad or the spindle is too tight somewhere and will request the seller replace the gantry. Thanks in advance for any and all help!
