Ok, I see. Thanks!

I also have the homing issue G0/G1: insufficient axes homed.

But it does not happen all the time. It can home fine, then it does not. I can't find a pattern, it can happens at different stages...

I'm using a Duet2Wifi.

Here are my congif.g and all homing files:

Thanks for you help.

@fma You need to put your M584 before M667 and M208. Look at the order dependencies here https://duet3d.dozuki.com/Wiki/Gcode#Section_M584_Set_drive_mapping. Also, it probably won't make any difference but M667 is deprecated and you should really be using M669 instead of M667.

fma

Ok, thanks. I applied all these corrections, but I still have the issue.

I tried to removed the U axis: not better.

deckingman

@fma Then I guess what's needed is some way of reproducing the problem - it's always difficult to diagnose when there is an element of "randomness" involved.

Unfortunately, I'm unable to help much more because I can't home my printer at all. Some of my end stops are on expansion boards and RRF 3 firmware doesn't yet work for homing with end stops on expansion boards.

M208 X-60:302 Y-100:305 Z0:320 U-1000:1000

I would propose as reason:
M208 X-60:302 Y-100:305 Z0:320 U-1000:1000
means X maximum distance is 362, Y is 405, but you home only 325 each in
G1 X325 Y325 F1800 H1
, so depending on your current position you reach one of the endstops or not, assumed, 0 position is not defined after turning the printer on. I would change to
G1 X500 Y500 F1800 H1
and the followong two also to be sure they reach the endstops..

If G1 X325 Y325 F1800 H1 reaches X immediately, M208 defines X/Y position as 302/305, but in reality Y may be at -100. So it will not reach the endstop with the following Y move, even when the first line reached an endstop. So better 500 for the following two lines also.

fma

The min values are wrong; I didn't noticed it because I home on max values. Anyway, total travel for X and Y is < 325mm, so the endstops are always reached (I'm using relative positionning). And in my tests, I'm close to the max positions, so carriage travels only a few mm before hitting the endstops.

And it was working fine with 2.02/2.03 firmwares; I just changed the S param to H param in the G1 moves.

fma

I confirm it is totally random.

Say I'm on the max position, both endstops X/Y activated. If I hit the homing button several times, I can see the machine homing X then fail, or Y, the fail, or none, or successfully home all axis.

But I find a workaround: I changed

G1 X-5 Y-5 F6000       ; move away from the endstops

to

G1 X-5 Y-5 F6000 H2    ; move away from the endstops

and it now works fine. If it can helps to find the problem...

Danal

This may or may not be related, I didn't completely follow all above... if it helps:

I have noticed that RepRap 3 on Duet 3 hardware gets "stuck" if the endstop is already triggered (physically) when a G28 is issued. Stuck meaning it won't successfully show as homed, and therefore won't G0/G1 (to move off the switch). Just won't move at all.

I've had to either manually back it off (forcing the steppers) or add something like an M564 (to allow unhomed movement) and a G0 back off of a millimeter or two (and then turn M564 back to normal), or similar, to my home... files. Of course, this back off would be problematic if the axis happened to be a physical max when the home... file was invoked.

Anyway, one of those two things is required to get that axis to move again. Not even a reboot will help.

fma

I though it was the case here, but even when I was not on the endstops, the problem occured (again, not all the time). And I was able to successfully homed even when starting from endstops position.

With the H2 param added on the mov away, it works all the time.

Interesting. Mine fails every time when already triggered.

Aha! Yes, I am on 3 HW (and of course SW). Therefore, my data point not relevant at all.

One other thing to try is adding M400's to your homing scripts to make sure that
moves finish before the start of the next move or the macro finishes.

fma

Ok, but the problem occurs inside the homexy.g macro. I will try to add M400 before moving back...

Yeah I understand that. The issue I was having (and still do to some extent) was that the moves to home both axes weren't actually finishing before the macro execution ended. When macro ends, it resets state so it was doing that before the moves completed and left things in a very weird and unpredictable state. The M400's inside the homing files helped (but haven't sovled the issue completely).
