the x,y,z movement isn't smooth, it's jerky, and loud, bed leveling doesn't work, homing doesn't work process obviously doesn't work. It's a dual direct, with updated firmware with Volcano hardened nozzles. Voltage on stepper drivers tops out at .5 before going to .01, I've tried tuning it closer to the .55 recommended. I finally did fix all the temp errors new rumba and fried PT100s. Any tips, thoughts or links to modded firmware that may fix the issue would be appreciated. I've gone through the setting up and wiring more times than I care to count, but progress is being made!
