@wilriker No didn't change the lead screw. but once i got stuff working. I did a re-calibration of all axis's.
Need a bit more fine tuning but 20 mm print was 20.23mm so cant complain lol.
@JoergS5 eventually I will be using one stepper, doing that. Yeah i didn't know about the spindles being off but that does make sense. I will take that into account and grab a long spindle to cut in half, well that's if i don't come across anything else to use for the z axis. (hyper-cube set up)
