Hey guys, I'm helping a friend with his Makergear M2 (I have one too though
![Very Happy :D](./images/smilies/icon_e_biggrin.gif)
) and he's gotten a replacement Rambo board (because he had the one with the non-removable fuse) and I'm not entirely sure what firmware to install. It's definitely not 24 volt since it's older (late January 2013) and I've installed M2Marlin.zip as well as M2Marlinx1619V.zip...but both have a funny behavior on the Z motor.
X and Y move and work fine, but it's like there is no torque in the Z movement. The motor is operating...but will not lift up unless I provide it a little assistance. Even moving down can slip.
What could I be missing here?
Thanks for any info,
Lon
