Issues homing X and Y axis

Ace1992

Hey Guys,

I apologize if this has been answered already, but I could not find an answer that would help me.
I am currently trying to setup my ultimaker 2 (Cartesian axis) with a Duet 2 wifi. Here is the firmware list:
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1 (2020-05-19b2)
Duet WiFi Server Version: 1.23.

I am having issues with homing X and Y, and most likely Z, but it wont let me home Z until I home X and Y. I have my endstops set as active low, because I think that the ultimaker uses normally open switches. When the switches are pressed the LEDs by the motor ports light up. However, when I press the Home X or Home Y, all that happens is the Z axis drops a little bit, then I get a G28 error saying "Failed to enable endstops". It almost appears that the X and Y axis don't try to move.
To trouble shoot the issue, I tried switching the endstops to active High. When I did that the Z-Axis would drop a little and it would say that the X or Y axis was homed. I am guess due to the switches being open. It would then allow me to move all the axis with the movement part of the web-control, and everything moved in the correct direction. I have compared my config file to a few others and I can seem to find the issue.

If you have any information, that would be great.

Thanks,

Andy

post the output of M119 without endstops beeing pressed and with endstops beeing presses.

Your M574 commands are wrong for RRF3. Instead of this:

M574 X1 S0 P"xstop"

Use this:

M574 X1 S1 P"!xstop"

Similarly for Y and Z.

Hey Guys,

Thanks for the quick responses.

With my current settings. When I use the M119 without the endstops being pressing it says X: no endstop, Y: no endstop, Z: no endstop, Z-Probe at min stop. With the end stops pressed I get the same response. X: no endstop, Y: no endstop, Z: no endstop, Z-Probe at min stop.

I then followed dc42's instructions on turning all M547 commands back to S1. Now when don't have the switches pressed I get X: at min stop Y: at max stop Z: at max stop Z-probe at min stop. When I have the switches pressed I get X: not stopped Y: not stopped Z: not stopped Z-probe at min stop. Which is the opposite of what I need.
For the wiring setup I have each sensor on the 1st and 3rd pins of the end stop plugins. Is that correct?
Here is my new code after updating as dc42 instructed.

@Ace1992 note the exclamation mark in DC42's command pin name. That inverts the pin which is what you want

Oh ok. Thank you for clearing that up for me. I completely missed that. I will give that a try tonight.

Thanks,
