bltouch
-
So I'm quite confused now. Is the BLtouch working or not?
Does G32 work to run the auto calibration?
-
@Phaedrux yes on p5 everything works if instead I switch to p9 the g29 and g32 the probe does not come out
-
Can you go through this section and perhaps create a new beg.g

do you think the problem comes from here?

I'm not sure. You cna use this tool to generate a new one: http://escher3d.com/pages/wizards/wizardbed.php
If it all works with P5 then that's not the end of the world. I just don't understand why P9 doesn't work.
-
I don't have M401 in my bed.g How come? maybe that's why it doesn't work
-
@nemecek if you set P9 mode, I would set P value of G31 lower:
G31 P500 X-45.712 Y36.357 Z2.5
=>
G31 P25 X-45.712 Y36.357 Z2.5The 500 was an example in the G31 section, but P25 is used in most documentation about BLTouch P9 examples.

@JoergS5
ok and for this reason that did not work in P9? I'll try tomorrow thanks -
sorry how do you save the delta calibration?
when i turn the printer off and on again i lose the g32 i had made ...
what do you think you can print like this? or it is too wrong
-
sorry how do you save the delta calibration?
M500 will save the calibration to the config-override.g file and you will need to add M501 to the end of your config.g to load the config-override.g file at boot time.
I don't have M401 in my bed.g How come? maybe that's why it doesn't work
With P9 the probe should be deployed automatically when needed, so no need to manually call M401, etc.

ok thanks for the assistance I will try today as joerg55 told me to set P25 instead of P500. if even this attempt doesn't work, I stay at P5. the bltouch does not lose quality right? and equal P5 or P9
-
@nemecek P9 has deploy/retract probing for the BLtouch and if there are firmware improvements, I am sure P9 will include improvements for BLtouch, but P5 not, because P5 is used for other probe types also. But if only P5 works, you have to decide and maybe go on with P5 until you know the reason why P9 doesn't work.

yes the best solution
-
hi i also tried p25 without success. sorry but here it must be inserted on channel 2 and correct?
-
@nemecek Yes that combination should work and result in
; Z-Probe
M307 H3 A-1 C-1 D-1 ; disable heater on PWM channel for BLTouch
M558 P9 H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
M280 P3 S10 I1 ; deploy BLTouch -
You must also check your config-override.g for a M307 H3 command that would overwrite your M307 H3 A-1 C-1 D-1 ; disable heater on PWM channel for BLTouch in config.g and comment it out.

I finally found the problem if I understood correctly H5 means that the pin comes out at 5 mm from the plate so the z goes down too much before letting out the pin if I put H50 then it's fine
but now i don't understand why i have 2 M558 this from errors one and to H30
the other is at H5; Z-Probe
M307 H3 A-1 C-1 D-1 ; disable heater on PWM channel for BLTouch
M558 P9 H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
M558 H30 ;*** Remove this line after delta calibration has been done and new delta parameters have been saved
G31 P500 X-45.712 Y36.357 Z2.5 ; set Z probe trigger value, offset and trigger height
M557 R180 S20 ; define mesh grid -
