Question/Suggestion about current manual delta calibration process
-
Hi,
I am currently working without a Z-probe so am using the manual method as available in the most recent firmware 1.19 RC1.
It works well.
However I am using "mag ball" mounts for my effector plates and for manual calibration I swap in a plate with a dial indicator mounted on it. This indicator is accurate to 0.0005".
When doing the manual calibration the up/down Z increments are 0.10 mm which is about 0.0040".
Would it be possible to add two addition up/down buttons with 0.01mm increments?
If so, could the manual calibration process benefit from the increased accuracy when it came to getting the dial indicator to read zero?
Thanks.

Command the print head down in small steps until the nozzle just touches the bed or just grips a sheet of paper. You may need to send M564 S0 to allow movement lower than where the firmware thinks Z=0 is. You may also wish to create a macro to lower the head by e.g. 0.02mm to get greater accuracy (G91 followed by G1 Z-0.02).
Found this in the calibration wiki.

I don't think the current (1.19 firmware) manual calibration routine will allow me to access a macro but I will give it a try.
The current routine pops up a dialog with a couple of buttons to move up/down by 0.01mm until it just touches the bed.
That dialog may prevent access to the macros.
Thanks.
