Delta Z triggered height
-
Guys i need some help for tweaking my deltas.
First of all i was wondering about the procedure to measure triggered heights by smart effector. So my question is a mathematics one sort of.
On the documentation is says that i need to specify the triggered height for the center of the bed and then every point on my bed config.
So the H parameter says it is triggered height at a point minus the triggered height on the center of the table .That means that if i have a triggered height -0.10 on the X0Y0 and -0.30 at a specific point X0Y128 the nnn is -0.40 ? Am i doing it right or i am on a wrong path ?

Can you point me to the page you're seeing this please?

part of the benefit of using a smart effector is that the nozzle is the probe so you should not need to set individual trigger height offsets for each probe point.

i am trying to fine tune my deltas and as far as i know i have to go trough the process that documentation says. i am printing alright but i want to go after for that perfect thing.

Have you actually measured a variance in trigger height based on XY location?

i am not sure i got what you asked. in every bed point of my 10's i got a different triggered height.. even in one spot ( let's say the center i got a different triggered height every time . on the X0Y0 there is a variation of one thousand of a milimeter no matter what i do ...!

Do this test at multiple points on the bed. Test each point multiple times.
Do you have variance over multiple probings at the same spot?
Do you have variance between different XY points on the bed? -

This is the procedure i follow. done this hundered times on each of my printers.

Yeap....

Yes

Can you share your config, homedelta, bed.g, M122, etc?

Is it meaningful variance? You've previously referred to it being "a variation of one thousand of a milimeter no matter what i do"
If it's a conventional delta, 20 tooth drives, 2mm pitch belt, 400 step motor, 16x microstepping, one microstep is six thousandths of a millimetre, so getting one thousandth repeatability is remarkably good, and I doubt can be improved.

What do you have in config-override.g?
