tool changer calibration
-
Hi boys im new her and i hope i get help i have a lot of research done but get nothing right working.
My case:
Duet 3 Mainboard 6HC 4x Tool board,
2x Z endstops stops on Z Max
mesh probe on my X Carriage for mesh probe.
and i want to make a Nozzle probe:
its a microswitch mounted on my Z (bed ) carriage close to my heated bed, i don't get the values on the Z
what i have to do if i want a fixed Probe for nozzles offsets in Z on my bed -

I'm afraid I don't understand what you're asking.

Hey i understand him. I think you want a switch for the different length of your nozzles. I am searching for the same thing.

This is a good way to start. He use parallel the bltouch. So it is a second z endstop. -
I have a tool changing system on one of my machines.
In that, I reference and level without a tool loaded, then have Z offset for each tool in the tool configs.
Once set, they should never need changing, or at least until you replace a nozzle.
To calibrate them, I just set the Z at zero in the tool initially, pick it up and measure the height the nozzle touches the bed, then put that value in the tool Z offset; done.
Check it prints OK and adjust the offset fractionally if it's not perfect.Accurately calibrating the X & Y offsets to be able to do multi-material prints is much harder - I've not done that so far, I'm still doing other tweaks on the machine.
