I completed my mpcnc about a week ago, and i cabribrated the whole thing yesterday. It's really accurate, but i have one small issue: when cutting from right to left ( cutting towards the top ) the whole Z axis starts to rumble.My machine's specs are:
1m wide 1m deep, 10cm legs, 30cm Z axis conduit & leadscrew length, 200w spindle, ramps 1.4 +3 drv8825 drivers ( x & y in series ) and single flute 3,175mm bits. The voltages are adjusted as told in the guides, and i use the ‘official’ mpcnc firmware.
I suspect it has something to do with the larger Z height, but before i start cutting the leadscrew, i would like to know for sure if this is likely to be the issue.
I tried changing speeds ( higher speed = less rumble, i only cut mdf at the moment ), i also tried less & more tension on the belts, but the problem is still there.
Has anyone experience with this issue? I’m fine with cutting the Z length ( i don’t need it that long anyway ) but if it’s not needed, i prefer to keep the rod as is.
Thanks in advance!
