This is what I put in homeall.g's place.

So you where showing me the code from homeall.g - I misunderstood.

That code you now have will work fine IF the individual homing files work.

You can strip it down to this:

; homeall.g
; called to home all axes

M98 P"homeZ.g"
M98 P"homeX.g"
M98 P"homeY.g"

But don't test it until you have verified that homing each axis by itself is working.

@fcwilt that's what I'm working on right now.

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.

@mac said in I could use some help:

@fcwilt it’s at the back.

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.

Since 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
