I am having an issue with the Z axis. I am using the X-Carve setup with the M8 Threaded Rod option. The Z axis moves more than it should. For example, a 2mm depth actually makes a 4mm depth and a 6mm depth actually makes a 9mm depth.
I think the problem might be the rod selection. I have a M8 2 pitch threaded rod with a 4 start. Does anyone know what the specs are for the X-Carve or Shapeko rods? I have a home built machine using an Arduino and CNC Shield, using the mentioned M8 2 pitch, 4 start rod.
When I use the Gcode sender, the Z axis is spot in regards to the depth.
Thank you for your help.
