Duet 3 end stops and z probe not working.
So, I’ve been trying to get the end-stops to work but when I home the x y or z axis the printer just keeps going into the switch and doesn’t stop. I’m pretty sure it’s my wiring but I could be wrong. Also when I try to manually move the axis, I can only move them about 200mm and I don’t understand why it’s only moving that much.
Please post your config.g and homing files.
What firmware version are you using? Should be 3.1.1. Send M115 to find out.
What kind of switches are they?
What kind of printer is it?
@Phaedrux here it is. Also, i'm using mechanical switch (3 prong) for the x, y, z axis connected two wires both outer prongs and using an inductive probe to level the bed(not sure if i can use a mechanical switch for the top and probe for the bed). The printer is a Cartesian i built it myself. I'm using 3.1.1 firmware.

Hi, please post the results of M122.
Also send M98 P"config.g" and post the results of that as well.
When you click the endstop switches does the endstop status in the DWC machine status page change?
@1997alex said in Duet 3 end stops and z probe not working.:
I can only move them about 200mm and I don’t understand why it’s only moving that much.
Are you sure the steps per mm for the X and Y axis is 200?

By the way, the heater for the bed and hot-end is disconnected.

Ok, that all looks alright.
If the status of the endstops is actually changing in DWC, the only thing to change for the endstop config is to remove the
!from the pin name.
; Endstops M574 X1 S1 P"!io3.in" ; configure active-low endstop for low end on X via pin !io2.in M574 Y1 S1 P"!io4.in" ; configure active-low endstop for low end on Y via pin !io4.in M574 Z2 S1 P"!io1.in" ; configure active-low endstop for high end on Z via pin !io1.in
As for the probe, your homeall is set to use the z max endstop. This is fine, but before printing or creating a heightmap, you should establish the Z0 position with the probe using G30 at the center of the bed.
@Phaedrux Oh, I see so they are working but not the right ones. The issue I'm seeing now is that when I move the connector to a different io pin it keeps the switch i don't want powered on and doesn't power the switch I want to work on that same io pin. I have two pins on the x axis and I'm trying to make one of the end-stops switches to work and not the other. From what I understand, I can only use one end stop for each axis. I added the other end-stops before finding out I could only use one.
@1997alex lol, fixed the last issue, it was a wire that was loose. thanks for the help.
I don't really understand what you mean, but if you've got it figured out, that's awesome.
