Bltouch setup need help

Elvis0z

Can I post a video here of what it is doing?

JoergS5

@Elvis0z most people make a youtube video and post the link here. Don't know whether you can post video directly, I suspect not.

Elvis0z

Ok I will try That

Here is the video of what is happening

JoergS5

@Elvis0z maybe its the
M203 X6000.00 Y6000.00 Z180.00 E6000.00
setting, because Z moves with maximum 3 mm/second, which will take forever at this distance on the video. Please set higher and try again.

PS the video was very helpful, this was a good idea!!

Elvis0z

should I put the same as x and y?

JoergS5

@Elvis0z you have trapezoid at Z, the stepper turns 5 rotations per second, your trapezoid has 2 mm for every rotation, so 10 mm/s, the value for Z should be 600 mm/min. The stepper could run 16 rotations/s maximum, but better be on the safe side.

Elvis0z

Thanks for your help.

Elvis0z

So just to make sure I have to home z before I can do anything else?

Elvis0z

Ahhhhh gets to the same point and deploys probe then nothing like in the video

JoergS5

@Elvis0z please see above, take 600. 6000 ist too much for the stepper.

the printer want to have homed all axes before it proceeds.

G28

Error: Z probe was not triggered during probing move
Error: Homing failed

Just keep getting this error

JoergS5

@Elvis0z can you make a M122 after the G28 test please and show?

An does G1 Z10 and G1 Z-10 move as expected when you run this commands directly?

When I do a G28 command once z probe deploys the console just spins around and I can't put any commands in till I restart control board

JoergS5

@Elvis0z first sorry for my G1 Z-10 and G1 Z10. This will not work because Z is not homed. The correct commands are G1 H2 Z-10 and H1 H2 Z10 to move even when the Z is not homed. Just to check Z can move at all at this position.

I was searching what this fast white LED blinking means, but I can only find fast red blinking (which would be eg white and black cables switched).

Can you please make an image of the wiring of the Duet Wifi and the cables at the 5-pin connector of the BLTouch?

G1 H2 Z-10

Yep moves up and down with new commands

JoergS5

@Elvis0z I have no more ideas.
Two things I found in my research:

often it was a wiring problem. Wrong wiring, wiring or connector broke or disturbance by heat or magnets
on reddit was a report of a damaged charge of BLtouch 3.1. But you tried 2 BLtouch, I think probability is low for this reason

I have only one idea left: please recheck wiring and connections. And the other idea to find out the reason for the error message of M98 P"config.g".

If I have a new idea, I'll tell you.
