Hi guys.
I'm going to try to give as much info as I can about my machine, so bear with me please.
This is not my first machine, but my first DIY. It is 1500mm x 1500mm with C Beam extrusions, dual C Beams on the X axis. 1610 Ball screws and 15mm Linear rails on all axes.
I purchased the following package on Ebay for the electronics, link below. I replaced the power supply with 2 48V power supplies.

All has been going pretty smoothly with the build and I now have everything together and all of the electronics wired up and the homing switches working.
The problem I'm having is that the Y and X axis at random times will stop and make a grinding/screeching noises (Z axis works fine). Also, the Y axis has dual motors and one will stop and the other will keep going?
The grinding/screeching sound like a voltage issue, but I think 2 48V power supplies should be plenty power this machine, and I have adjusted the speeds and acceleration to fix it, but it happens no matter the speed. I am squaring the gantry simply be measuring the right side gantry to the front of the machine and setting the left side to match.
So I'm really having trouble finding out what is going on.
Anyone have any ideas about this? Mechanical? Power issue? Electronics issue?
Thanks for looking and any suggestions you have.
