Need help - Duet 3 mini 5+ and Prusa Mk2 - how connect z-probe?

polygon

Hey all.

My Prusa Mk2 controller board died so I got a duet 3 mini 5+.

I followed this tutorial: https://www.cnckitchen.com/blog/prusa-mk25s-duet-3-mini-5-conversion

And everything is working except the z-probe. I have no idea how to setup that up or how to test it. The tutorial was written for an MK2.5 and it has a different z-probe with 4 wires (Black, Blue, Brown, White) and mine doesn't have the white.

I tried to do a bed probe but it just crashed into the bed.

What's the proper way to wire an MK2 to a Duet? How do I test if the z-probe is working (without trying to probe and crashing into the bed)?

Any help would be very appreciated.
Thanks!

Can you give us some technical details about the probe you have? Not everyone is familiar with the Prusa line.

Pretty much any probe can be made to work.

Also please post the results of M122 and M98 P"Config.g" as well as your full config.g and homing files so that we can get a better picture of your current setup.

This is the z-probe: https://www.prusa3d.com/product/pinda-probe-v1-no-longer-offered/

I couldn't find any other specs or wiring data

Here is the M112 snippet: https://www.codepile.net/pile/54qY9x4P

Here is the M98 P"Config.g" :

M98 P"Config.g"
HTTP is enabled on port 80
FTP is disabled
TELNET is disabled
Error: Filament error on extruder 0: noFilament
Error: in file macro line 171 column 8: M18: expected number after 'E'

And here is the full config.g file: https://github.com/CNCKitchen/PrusaDUET/blob/master/SDCard/config.g

Thanks!

You'll have to identify which wire is signal, ground, and input voltage.

You can use the Z probe input, and I believe the pinda uses 5v, so you'll need to source that from another connector. Possibly the paneldue connector if you don't have one of those connected already.
