Hello everyone.
I have a Duet Ethernet as well as a panel Due. I purchased this a few years back to build a printer I've yet to build however now I would like to connect it to my TronXY which has lost it's board. (Typical i3)
I think I have it updated, I went from 1.02 to 3.3. I'm trying to use the online config tool. I have a few issues still but I'll tackle them one at a time.
The machine won't home properly, I've tried changing the home files however it doesn't seem to respond to the changes.
If I press home X for example, the Z will move up a bit, the X axis will move about 10mm, then the Z will move back down. DWC will say that axis is homed even though it hasn't travelled to the endstop.
The X and Y endstops appear to be working, they light up the board when depressed and also seem to work during the fan test.I'm using the Ender 3 in the config tool as it is somewhat similar to my printer as a starting point.
I suppose I would be asked to upload the code, I'll have to go back and put a fresh one on there due to the changes I have made that may not make sense nor did they do anything.
Is there a special way to submit the code to this website so it shows up in a separate box like I see on other threads?
Thanks, al

Please post your config.g as well and let us know where your endstops are physically located. What kind of endstops they are and how they are wired.
You can send M119 to see what the endstop status is when the switch is pressed or not. That will give an idea as well.
Can you also confirm that -x moves left, +x moves right, -y moves head to back of the bed, +y moves head to front of the bed.

Thanks for your response, it's appreciated. The X endstop is located on the left, the Y endstop for the bed is at the back of the printer.
They are normally open and connected to the outside pins of the Xstop and Ystop on the Duet.-X moves the print head left, however -Y moves the bed back essentially moving the print head to the front of the bed. I suppose I'll have to switch the Y.
This is the result of M119 with the switch not pressed:
M119 Endstops - X: at min stop, Y: at min stop, Z: at min stop, Z probe: at min stopWith the endstops pressed:
M119 Endstops - X: not stopped, Y: not stopped, Z: at min stop, Z probe: at min stopHere is my config.g:

no your config is correct. The Y endstop is at the low end as your print head is at the front of the bed.
Since your endstops are showing triggered when not pressed you will just need to invert the signal.
Change this
M574 X1 S1 P"xstop" M574 Y1 S1 P"ystop"To this
M574 X1 S1 P"!xstop" M574 Y1 S1 P"!ystop"Adding
!to the pin name inverts the signal. -
@phaedrux That did it thanks!
I have a few other issues I'll attempt to resolve, I'll start a new thread if I cant!
