I built an LR3, SKR Pro V1.2 kit, all part from V1E, using Estlcam 11 and with everything working, I was able to cut the 3 strut parts. Now with the struts mounted and loving life, I went on to some practice cuts, sweet… everything’s working great. Since there are bigger fish to fry, I started on a torsion table. The first one and a half sheets cut perfectly. When the LR3 started the second half, a couple of cuts where not in the correct place. Figuring it was something I did wrong in Estlcam I called it a night. This morning I made new gcode and was also going to check the set screws on all the gear motors.When everything checked tight and solid, I homed the machine to try the new gcode.
Everything was going good until it started heading to another wrong location but it was not the cordinates it went to previously so I shut it down. Powered it, homing it, it started going home then the right Y motor stopped, left one still driving. Shut it down, realigned the gantry and restarted, homed then both Y motors started moving for about 10mm then the left Y motor stops with the right one still driving. I left it alone for about an hour then tried it again. This time during homing, the Z worked correctly, X worked correctly but both Y motors move in the wrong direction (from home) and went for a distance of about 2mm then stops. Tried a few more times to home, same story, Z and X work correctly, Y just move a couple of mm in the wrong direction. (things that will make you go hmmmm) Guys I’m lost, starting to think it might be the board or maybe drivers. Any thoughts would be appreciated.
