BL-Touch to Alfawise U10

Phaedrux

It sounds like the BLTouch is not getting power if it's not doing a self test. Does it light up?

Pertti

@phaedrux
No light. I´ll check the wires.

Pertti

@pertti The BL touch wire connector was 1 step aside in the motherboard.
I´ll continue the experiment soon.

Pertti

@pertti Now it gets power! At the start the Bl-touch moves back and forth . After homing it twinkles red light.
I have no idea weather the BL-touch is supposed to be the z-endstop or not. Is my configuration ok?

@pertti do M401 and M402 work to deploy and retract the probe?

@pertti Do you have a Z stop switch as well as the BLTouch? If not and you want to use the BL for Z homing, you'll want to change M574 Y1 S1 P"ystop" to M574 Z1 S2 in your config and define a Z homing macro.

This blog post here give an excellent overview of the macros:

Remove the M280 command in the config, that belongs in the Pin Down macro.

M401

M401 deploys an d M402 retracts the probe.

Pertti

@lo-fi Yes I have a remainig z endstop. I do not know is it worth saving. Less moving parts sounds good. And if I changed the bed surface thickness then it is easier to handle with z probe.

Share your homeall and homez here and we can tell you if anything needs to change. In general though, to home Z with the probe you need a G30 command. And before the G30 you'd need a G1 X Y command to move the probe into position. Ideally the center of the bed.

I´ll check this, looks good. https://betrue3d.dk/bltouch-on-duet-wifi-configuratio-and-usage/

Remove those lines in homeall and replace them with

G90
G1 X150 Y150
G30

And in homez, remove those lines and replace them with the same.

@phaedrux
Thank You all! First testprints going on! So far so good. I removed the z endstop and replaced it with z-probe.
