Y endstop getting no respect.
-
So … I have a Cartesian printer that I'm setting up with a Duet3dWiFi. Just by happenstance of wiring, X and Z are "forwards" and Y is "backwards"... so I have:
M569 P0 S1 ; Drive 0 goes forwards
M569 P1 S0 ; Drive 1 goes backwards
M569 P2 S1 ; Drive 2 goes forwardsThen later on I have:
M574 X1 Y1 Z1 S0 ; Set active low endstops
... now I've also tried Y2 there... but the Y axis (the printbed in this instance) slams against the Y stop and then proceeds to grind the belt for awhile. Now... the LED representing the Y stop lights... so what gives? How do I fix this?
For reference, here's the totality of config.g:

Please test your endstops as described in the commissioning tests at https://duet3d.dozuki.com/Wiki/Step_by_step_guide.
What type of endstop is it?
-
OK. I solved that, but I ended up with more confusion.
For the X, say, -ve X travells towards the endstop. Pressing "home" travels to the endstop and then sets the X position as '0'.
Y is backwards, but it's configured that way (see above). -ve Y movement moves towards the endstop, but after pressing 'home' for Y, and the bed travelling to the endstop, the Y value is set to 200 … so the bed effectively cannot move (200 is the max Y).

NM. Solved this problem. The web config somehow put in a y2 in the endstop list rather than y1. Odd that homing still went in the right direction.
