Hello All,
I’m trying to setup a new desktop 3D printer (Creality Ender-2) with smoothieware. Being new to this whole hobby and smoothie as well, I’m having an issue with the motion on the Z axis. As the specs for this printer are not published and the stepper motors used have no markings on the at all, I have to create my config.txt by actually measuring the linear motion of all axes. The steppers on the X,Y axes work as I would expect (per my configuration), but when it comes to the Z axis, given the same configuration parameters the linear distance per move is much less (G0 Z +10 yields a 2mm distance).
Assuming the motors are the same, should this not move the expected 10mm.
I verified that it was not coming from the board driver’s by swapping the Z and Y cables and repeating test. No change.
Here are my motor definitions in config.txt :
