Thanks a lot, this fixed it.

@jay_s_uk didnt really showed up when searching for it, the pinned macros showed up but they are a bit bulky

Merry Christmas Together,

Ive got around installing a SZP to my idex, since ive got a probe already on the primary toolhead ive got it installed on the Secondary Toolhead.

Got it all configured the probe works too.
My issue is that the Scanning and resulting Mesh is Rotated by 90° i suspect its because the probe is mounted on the U Axis instead X Axis, the mesh is also configured to use the U Axis instead the X Axis.

Running a Duet 3 Mini 5+ with 2 1LC Toolboards and the SZP Sensor
Firmware version for the boards is 3.5.3

Ive noticed that the mesh is off when ive started configuring the probe offsets and mesh size
in the Image Below ive set the Mesh to be larger than the Bed is in the X+ Direction, the Mesh shows its dropping in the Y+ Direction

The Scanning also happens towards the Y Direction instead of X Direction
When running the Mesh Misconfigured with the X axis instead of Y axis the Primary toolhead "Scans" in the X Direction

@jay_s_uk didnt really showed up when searching for it, the pinned macros showed up but they are a bit bulky

I where looking for a easy method to test how much Accleration i could potentially run on my Printer.
Klipper has that nice macro written by Andrew Ellis that makes it easy to run tests Automated so ive looked into creating something similar to test how far i can push the Accleration at a set speed

Resulting in the Following Macro

;-------------------Accel Test Macro----------------------------------------------
;this Macro aims to create random movements at set speed and set Accel
;There is a chance that this macro causes a Rapid Movement towards the Min Axis point the macro takes X0 and Y0 as Origin

This Macro takes the machine limits in X and Y (expecting Home to be at the Min point)
and then puts random movements within the Machine Limit at the set speed and Accleration
by default it doesnt increase the Accleration with each Iteration but can be configured to do so with a Parameter attached to the Macro Call

its not perfect but gave me useable results
might be helpful for others so i post it here.

Something to consider because of the Random Movements is that its not 100% repeatable but should give more realistic results due to being closer to actual print movements

@dc42 nothing, would guess that the probe draws to much for the 5v rail to actuate the pin.

I take the L on this one and look for a different solution for replacing the BL touch.

@dc42 powering up the system, cant command a self test manually, wont get executed after the initial selftest

the Silkscreen Print on the Probe itself matches what the Usermanual and the page from treamgloomy shows

ive used the teamgloomy page for reference, and to verify the correct order of colors.
https://teamgloomy.github.io/fly_e3_v2_bltouch.html
did compared the Original Harness for the BL Touch with the one for the Microprobe and both have the colors in the same order

will provide the other stuff shortly.
but i dont think its wiring related. Connecting a BL Touch with the same wires doesnt cause this issue.
the pinout of both probes is the same, ran the BL Touch for over a year on the Toolboard with no issues.

Here is a picture of the Crimps on the Connector facing the Toolboard, other side is facory Crimped.

Good Day,

I want to replace a BL Touch on one of my Printer with a Biqu Microprobe due to the smaller formfactor giving me a more favorable probe placement.
With the BL Touch connected everything is fine, connecting the Microprobe causes the Connected Thermistor to get lost, causing the hotend to go into a Error state.
The Printer where running with the BL Touch now for a few months in this Configuration

The printer is running as a Idex equiped with:
Duet 3 Mini5+
2 1LC Toolboards
2 Mosquito Magnum each running a PT1000
2 BMG-M Extruder
2 Roatating Magnet Filament Monitors
Running on 3.4.6

Changed the config from the Working BL Touch settings to:

; Z-Probe
M558 P9 C"^!20.io0.in" H7 F250:30 T8000 A20 R0.75 S0.01     ; BL Touch
M950 P0 C"20.io0.out"                                ; BL Touch Servo Pin
G31 P25 X-38 Y-3.8 Z2.12                        ; set the trigger height and Offset BL Touch 2.55
M557 X5:220 Y-17:220 S50                            ; define mesh grid
M376 H10                                            ; Taper height of 10mm (fade)

Deployprobe.g and Retractprobe.g got configured to support the new probe

M42 P0 S1
G4 P500

The Behavior i get with a BLTouch connected:

• Powering on the printer works
• Self Test of the Probe works
• Printer goes to Idle
• Pin Deploys when configuration is adjusted for the probe

The behavior with the Microprobe connected:

• Powering on the printer works
• Self Test of the probe Works
• after a second or two the Hotend Cooling fan of the Tool where the probe is connected to turns on
• the Thermistor reports 2000°C
• Pin of the Probe doesnt get Deployed when sending a macro containing

M42 P0 S1 ; Turn on pin so it deploys
G4 P500 

ive tried to see if the cable is the issue, but swapping in the BL Touch on the same cable doesnt cause the issue.
The pinout of both probes is also the same
