| Oct 30, 2019 at 16:05 | comment | added | 0scar♦ | @user77232 Why not ask that as a separate question? Note that I would not be worried from micrometer differences (thousands of a mm). Note that R. has a point, but it is impossible to measure everything correctly. | |
| Oct 30, 2019 at 15:17 | comment | added | user77232 | So how does one do a calibration cube with a CoreXY printer, where you get different values on the micrometer for X and Y ?!?!?! | |
| Oct 29, 2019 at 20:19 | comment | added | R.. GitHub STOP HELPING ICE | I'd go so far as to say tuning steps_per_mm does not make sense at all; it should be computed from the mechanical specs of the parts, which in turn should involve clean whole number ratios with things like nozzle size/line width. Whenever I played with trying to solve problems by tuning them, rather than mechanically, I ended up with nasty aliasing patterns in skin surfaces because the tuned values did not evenly divide. | |

| Oct 29, 2019 at 14:09 | comment | added | Trish | @user77232 set them to be equal first, then calibrate. | |
| Oct 29, 2019 at 13:42 | comment | added | user77232 | Ok, so I need an actual answer: Do I reset the steps/mm in the firmware and try invest in sorting out the hardware or do I mess with marlin to get it to straighten out? | |
| Oct 29, 2019 at 13:17 | comment | added | 0scar♦ | @user77232 I doubt that the manufacturing tolerances of steppers, pulleys and belts would make that much of an impact. My CoreXY is running with equal X and Y steps per mm and produces square products. | |

| Oct 29, 2019 at 0:34 | comment | added | user77232 | ok I assert that it is possible that there are variances in the tolerance of the motors, pulleys and belts. The drift in the values was my attempt to compensate for those variances. Would that be something that I compensate for in hardware or firmware? | |
