Hi Guys,

I hope I put this thread into the correct forum. If not, sorry.

I want to change the Z-height. If I enter G1 Z0 the nozzle is 0.6 mm above the bed. I want to have it on 0 (= the nozzle scratches a piece of paper).
What do I have to enter into the config or the config-override file? As far as I understood you need the currect information of M665 and M666, correct?

I have a Anycubic Predator.
Firmwarename: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Elektronik: Duet WiFi 1.02 or later
Firmware Version: 2.0(RTOS) (2018-06-05b3)
WiFi Server Version: 1.21
Web Interface Version: 1.22.6

Config.g file
M665 R227 L440 B185 H455
M666 X0 Y0 Z0

Last code in config.g
M501

config-override.g
M665 L440.000 R227.230 H453.007 B185.0 X0.199 Y-0.293 Z0.000
M666 X-0.850 Y0.932 Z-0.083 A0.00 B0.00

If you need further information, please let me know.

Thank you

Hi DC42

thank you for your help. I was able to make the G32 and the G29 and get a relative good result.
One more question
Is it possible to increase the probing points, so the mesh is tighter?
xmin,xmax,ymin,ymax,radius,xspacing,yspacing,xnum,ynum
-180.00,180.10,-180.00,180.10,185.00,20.00,20.00,19,19

I would like to have 10 mm spacing between the points if possible.

Is there a tut how to increase the probing points?

i did it according to the calibration tutorial. The bed seems now to be "better"

But this doesn´t help me with the change of the Z height. Everytime I home the towers, the Z0 is above the bed. This can´t be correct?! I need a correct Z height before I can calibrate the bed correct, or not? And of course to print afterwards on the correct height.

How I change my Z0:
Home all towers
Move all towers down to +1,65 mm (bed scratches the piece of paper)
G92 Z0

After homing the Z0 is again on +1.65

What step is wrong?

@oliof: then the homing should not work correctly, right? But it´s working, so the endstops on the top for the axis should be ok (?).

Other problem (maybe part of my general problem).
I´m homing. In the webinterface I see the headposition: x0 y0 z455
this seems correct.
then i move the printer head down to 1.90mm (this is the correct z0)
I change the z=0 hight with G92 Z0 to 0mm
after homing, the Z0 is again on 1.90, not 0.00 mm
Why is the homing changing the Z0 height?
How can I set the Z0

Hi Guys,

I´m trying to autocalibrate the bed for my Anycubic Predator, but I´m failing. Maybe you can help me with explaing what I´m doing wrong. I have a Pertinax 1 mm added with Tape to the bed. I´m using the microswitch probe of the Predator.

I got the files from a buddy who has the Predator and the Duet Wifi 2 too. Maybe there are errors I can´t see.

This are my steps how I try to calibrate:
Home all
nozzle down to bed to a distance of ~0.10 mm
G92 Z0
G1 Z25
adding the probe
G30 Z1
Adding the distance to the config.g (line G31)
restart as the config is eddited
homing g1 25
adding the probe again
G29 for probing
M500
leave the probe on the nozzle
G32

0_1559466263667_config.g
0_1559466283874_config-override.g
0_1559466292368_bed.g

Any help is appreciated.

Sorry for my bad english

Best regards
Sascha
