BIQU Microprobe how do I set it up?
-
I am having trouble conneting a BIQU Microprobe, v. 2
It claims to be compatible with BL-Touch wiring. I have fully working BL-Touch connected to a Duet Toolboard.
The instructions that comes with the BIQU Microprobe warns that not having correctly configured software may damage the probe.
Checking the instructions on BIQUs site I understand it as for Duet board nothing needs to be changed.
However when I connect the BIQU probe I get an error message stating that the toolboard stopped reporting status and the hotend fan stops. If I disconnect it the fan starts again. I am suspecting something gets shorted.
Now I have probe number 3, and I do NOT want to fry something.
Fw version 3.5.3 on both Mini 5 board and toolboard.
Condig.g below.
How do I configure/wire this?

See here for microprobe config changes for RRF. It doesn't use a servo so you don't use an S in M950. You also need to change your deploy and retract macros.
Don't forget to invert the probe for the V2 as well -
I made the following changes to config.g (BLTouch config commented out below)
; Z-Probe M558 P9 C"^!121.io0.in" H3 F300:100:100 T18000 A6 S0.04 ; set Z probe type and the dive height + speeds M950 P0 C"^121.io0.out" ; create pin 0 for BIQU Microprobe ;M950 S0 C"^121.io0.out" ; create servo pin 0 for BLTouch ;M558 P9 C"^121.io0.in" H3 F300:100:100 T18000 A6 S0.04 ; set Z probe type to bltouch and the dive height + speeds ;################################### G31 P500 X-26.6 Y-18.6 Z1.99 ;Set Z probe trigger value, offset and trigger height.I crimped a new cable. Joined the two ground wires from the probe to the one GND on the toolboard.
As soon as I connect it the DUET halts. Disconnecting it, the DUET somewhat recovers. Restarting the DUET it is all fine again.Connected BLTouch with new cable and reverted the config, it all works as before/expected.
Can the probe have been damaged by the S0 in the M950 command?
I have several probes (BIQU Sale) to try with but only one compleatly ontouched/tested that I am saving until this has been sorted.

@fotomas I can't see anything wrong with your wiring.
I'm not aware of it being possible to damage when programmed as a probe. We do have a few users who haven't been able to get one working recently though. I've only ever tested a v1 microprobe. I don't have a V2.
