@mac said in I could use some help:
This the first effort to home X and Y.
OK X is behaving very strangely.
But as to Y:
Is the Y endstop at the front of the machine or the back?

@mac I see that the Duet Mini 5+ does not have on-PCB pullups on the IO pins.
You need to go to the RRF configurator and select "Active low with pullup" if you are using normally-open switches connected to ground as endstops.
Without a pullup, every time a stepper motor starts moving, your machine will start to get signals indicating the endstop switch is being pressed.

@fcwilt it’s at the back.

@alankilian sorry to disappear, texting on this iPhone 8’s a bitch. I’ll make that change and post a video of the results do you can see the results.

So you have a moving bed.
To get to the max end of Y the bed moves toward the front?
To get to the min end of Y the bed moves toward the back?
But stepping Y by minus 10 caused it to move toward the front?

@fcwilt yes, that is what’s happening. The bed did touch the endstop and then back off; that’s an improvement.

Here's the problem.
When you tried jogging Y by -10 it went toward the front? Correct?
But the homing moves were supposed to be:
- a minus move
- a plus move
- a minus move
Based on the jogging test it should have moved:
- toward the front
- toward the back
- toward the front
I think there are two problems:
- the normal/reverse setting for the Y stepper is wrong (see M569 P0...)
- the steps per mm are wrong - too few (see M92)
I would like you to:
- change the M569 setting from whatever it is to the other setting
- try the home Y test and observe the movements
- try the jogging test and verify the correct directions
- if the directions are correct find some means to measure a move of, say, 100mm and see if a 100mm jog moves that distance.
Thanks.

toward the frontSince it's a bed-slinger in Y, isn't a PLUS move going to move the bed towards the FRONT? (Move the head towards the +y part of the bed.)
I may be confused.

Correct (about the move, not about being confused).
But according to mac a minus jogging move was moving the beds towards the front. I can only go by what he posts.

@fcwilt Y homes like it should. None of the + moves work. When I -10 it moves FORWARDS.

I understand about the jogging move.
And since it is wrong you need to change normal to reverse or vice-versa in the M569 for the Y stepper.
That should get jogging going in the right direction.
IF it does try homing Y

@mac That's where the code for my Duet3D Mini 5+ is today. Thank you to @droftarts , @fcwilt , and @alankilian for all their valuable contributions to this effort.
