DEFAULT_AXIS_STEPS_PER_UNIT

Hello, back I have the right to print well, I desire to deal with a doubt:

Why the DEFAULT_AXIS_STEPS_PER_UNIT because that Z-axe is 3200/8 (=400), if at TMC2130_USTEPS_Z that is asserted as 16 microsteps; so, 200 steps/rev *16 microsteps divided by the pitch of leadscrew (2 mm) should be 3200/2 (=1600)

Regards.

Are you sure the lead screw key is 2 mm? Measure her screw pitch and also let me know.

Hello tim-m30, many thanks for responding for this reason fast, however it to be a type of confusion of ideas that was clarified through this: command vs pitch

RE: DEFAULT_AXIS_STEPS_PER_UNIT

According to this, return the "pitch" of the command screw is 2 mm (T8-2), early out it has 4 start the "lead" (axial advancement per revolution) have to be 2*4= 8 mm.

RE: DEFAULT_AXIS_STEPS_PER_UNIT

But now I have one more issue (that likewise fits in this topic).

I supplied GT2-20 sheave for both X and also Y axes, so due the 20 this pulley, I adjusted DEFAULT_AXIS_STEPS_PER_UNIT from 100 to 80 and everything go OK except for the "4-points calibration" of the XYZ Calibration:

During bed calibration allude 1 the 4, the PINDA finds the calibration one wellBut at bed calibration allude 2 of 4, the X-carriage goes too much to the appropriate (in truth hit the x-end idler) and thus start searching for the calibration circle in ~ wrong location, failing at that point.

Now, ns am certain that this fail (X-carriage walk too much to the right) is pertained to GT2-20 pulley-block (their actions per unit), due to the fact that I published a 16 teeth pulley-block on PLA and also the 4-points calibration finished an ext or less fine. That course, I offered that printed pulley simply to confirm that the 4-points calibration perform not usage the DEFAULT_AXIS_STEPS_PER_UNIT

In short, go anyone know in which component of the firmware have to I change the procedures per unit for the 4-points calibration routine?
