thanks alot dc42 that fixed it right up - its working like a charm now, added to the config.g the P4 I1 which is necessary for the probe type and set the G30 in the z and all, and everything is working fine now.

Yes it does, as the whole x axis lifts from the microswitchs once the nozzle taps the bed with an activation distance of around .91 mm

It works like this https://youtu.be/eFywzPM9lfA

I am trying to use them as a microswitch probe, as outlined in the z probe settings, is this not possible with duet?

Have you looked at the NES-350-24 mean well - its what i just ended up replacing the internal power supply in one of my printers with. or are you looking for a completely enclosed unit?

it is what Robo used originally as a z probe in the marlin firmware. it triggers once the weight of the x carriage is lifted from that microswitch on either side of the carriage.

So I decided to replace everything in the robo3d except for the chassis and most of the steppers/switches. I changed the system out to a 24v power supply and hooked up a duet wifi with an SSR to run a 110v bed heater. I hooked everything up for the motors and endstops originally with the Z endstops (there are 2 microswitches installed in a "floating" z axis mount as you can see here https://help.robo3d.com/hc/article_attachments/115003728811/End-Stop.gif). When I hook the microswitches in as z endstop and home everything is working fine.

After getting everything working that way, I changed the endstop over to the E0 endstop header and updated the firmware to use the zprobe as the endstop for the z axis. I then ran the commands M558 P4 (also tried P6 incase I screwed something up) and looked in the machine properties and manipulated the endstop manually to verify that it triggers. and it did under endstop 3. I also verified in the Probe box that it reflected the P4 command (as well as running M558 to get current settings). Once all of this is completed i hit home Z axis and the printer drives into the bed (and I have to hit emergency stop to not damage the printhead/etc). Am I looking at things wrong here - I tried following the instructions on the https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe page modeling it after mode 4.

I am running 1.21 firmware on the board currently.
