So, i've had this gremlin for 2+ years. My machine will be running, i'll hear a grinding noise, and i've lost X, Y, or Z position, and my sheet is ruined. Sometimes it happens once every 20 sheets, sometimes every 3 sheets. The problem is definately NOT physical, i've had every stepper off, gears are tight, teeth are good, all the V rails and teeth are good. Verified all the grounds, no issue there.
I am running a laptop, no internet, no other software. Automatic updates, etc every non essential service is turned off, i followed the guide on the forums i found to do this. Using the USB hub that came with my shopbot. In speedtest i get 74.9 I am cutting at 4 inches a second, and my jog speed is 6 inches a second (i think, whatever the factory setting is) I have no idea what to do. My machine had two other issues since day one, it's more or less been a lemon since i bought it new. It leaves a nub on every single part, and my proximity switches never worked right since day one.. it could be out in the middle of the table cutting away and it will say "stop hit" constantly, so it's disabled.
I thought 74.9 would be fine. I have a prs standard 48X96 with a 2.2 hp yaskawa spindle. Has anyone tried a desktop with USB 3.0 with a USB 3.0 hub, and what kind of speeds are you getting? seems to me a serial port would have been a better way to go than USB.
