Z-Height

[Brouwi]

It is the standard Probe that comes with the QQ-P. It's a switch.

I see. So X and Y offsets of this are 0, so in bed.g H parameters should be 0 as well because trigger height should not change, why you have different H parameters there?

[Brouwi]

@aidar Good Question...
So I can set all Z values in the G30 lines to 0 (zero)?

[JoergS5]

@Brouwi No the H value, or remove H value, default is 0.
The explanation is in https://duet3d.dozuki.com/Wiki/Gcode#Section_G30_Single_Z_Probe

The probe is in fact very interesting. How is it removed after probing? (You want to print after probing, I suspect). Edit: I found the answer on https://www.youtube.com/watch?v=vWdklcVWtpQ&t=90

@JoergS5
Thanks!
Regarding the probe; the idea is that as the bed on a Delta stays stationary, you don't need to probe before every print.
As you can see in the video the probe attaches magnetically to the carriage.

Maybe I can ask you another question... I am getting an error message saying the height map cannot be loaded. Any suggestions?

Have a good sunday (Schöner Sonntag)!

@Brouwi thank you for your nice wished, Schönen Sonntag also!

According to https://duet3d.dozuki.com/Wiki/Using_mesh_bed_compensation you need to call G29 to run the probing sequence and save the heightmap. You will see an image of the result also, so you know how even your printbed is.

The complete Delta calibration is more complicated and has a few steps, they are described in https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer

@Brouwi You can load your already saved heighmap by G29 S1 in your slicer starting script for example. Anyway, this command can be used after homing your printer, so first G28 and then G29 S1. Assuming you have done G29 at least once before.
