"G28 Error: G0/G1: insufficient axes homed" after months of use

[ignacmc]

Hello to all

Today I was going to print in my Predator Delta (Duet3Mini5+ with optical endstops) but just after start up and connecting to the network, when I try to home the axes, the motors didn't even energize and I got the error "G28 Error: G0/G1 insufficient axis homed". What can it be? I have not touched anything in the wiring or electronics for months, and I have not upgraded the firmware since 3.3.0 release. I have been printing all this time without problems.

Did the way you call G28 change at all? There are different macros for G28 X, or Y, or all of them, etc. Maybe one of your macros is not playing nicely with a new slicer start g-code.

[ignacmc]

@bot No, in fact if i just issue G28 from the console, the error appears

Hi,
If you didn't touch anything (and before was working) it sound as the endstop are not read correctly.
Try to clean all of them. Look if the red light are operational.
Have you checked all the endstop? Try a singular independent move to see if all of them work regularly:
Testing the motors and endstops individually
https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareDeltaPrinter#Section_Testing_the_motors_and_endstops_individually

Not related now because you receive the error soon as you try to move, but it could be useful in future: When the head was placed on the extreme part of the bed and try to home is also happened that in the home.g this line had the X Y Z parameters too small and received your same error:
; Move all towers to the high end stopping at the endstops (first pass)
G1 X640 Y640 Z640 F2500 H1

I'm at shortage of other ideas... hope some more expert can provide more suggestions

[Phaedrux]

Can you check your endstop state with M119 and post your full config? Also please send M98 P"config.g" for good measure and share the results?

[jay_s_uk]

@ignacmc post your config.g please

[ignacmc]

@phaedrux

[ignacmc]

@jay_s_uk config.g

Here you have it...sorry for the verbosity of my comments

[jay_s_uk]

@ignacmc nothing i can see if your config file.
can you post homedelta?

[ignacmc]

@jay_s_uk homedelta.g

[jay_s_uk]

@ignacmc nothing in there either that would cause issue

[ignacmc]

@jay_s_uk Yes, I have been printing with these config files for months without issues. I suspect some hardware problem. As I was going to replace my LDO 0.9 motors for OMC equivalents, I will do it and recheck all wiring at the same time...

[dc42]

@ignacmc here's the problem, in your homedelta.g file:

G1 X0.01 Y0.01 Z0.01

Either add H2 to that line, or replace it by:

M17 X Y Z ; enable motors for stealthChop tuning

M17 is implemented in RRF 3.3 and later.

[ignacmc]

@dc42 David....you are a father to me! It did the trick...

Stupid me, I forgot I have made that change a few days ago while researching here how to tune Stealthchop and didn't print since then so I was not aware of the problem I had just created.

Today in Spain is the Fairy Kings day, when tradionally Christmas presents arrived. This has been a very nice one!

Thanks for your outstanding support!
