I was running a test cut when the Z-Axis started to not work.
I first checked the V-Wheels if they was too tight but was ok. Then checked the belt tension and was ok. So I noticed that the motor pulley metal insert was really loose. I tightened them back.
Now, after a test cut, when the machine have finished the work it have not raised up the Z-Axis when it return to the home position ruining the work (but was a test and not really a problem).
But now the Z-Axis won’t work at all! I disassembled it because I thought the motor was screwed and noticed that the motor get inverted command: When I set up the machine for example, if I told to make 5 step down, the motor make 3 step down and 2 step up! (just an example)
All the other axis work nice and smooth! Any advice? I first thought about a wiring problem into the terminal block, but the green led on the G-Shield are all ok!
Since the issue was with the z-axis, That one needs to be checked…nothing wrong with going through them all just to verify. I check all of mine on a regular basis just to make sure.
@ErikJenkins Sorry to bother again, but seem that the machine is sort of losing steps at some point of the cutting. And it goes totally out of path. Any idea? I was cutting just a 0,5mm depth! It loose steps/going out of path on the left side of the machine when cutting a small curves.
