Expectation fault or actual fault

[Garfield]

So I've been setting up a coreXY and pretty much all going swimmingly except the XY gantry behaviour.

If for example I send a command from the DWC for X of +50 the extruder moves diagonally - surely the Y stepper should also be rotating - I did not ask Y to change so why is it ?

Consider that these axes have never been homed, I don't have the end switches wired up yet.

Even so if I ask for +50 X via the DWC dashboard I don't expect to get +50 Y also. Are my expectations correct ? - why is only one of the X Y steppers turning ?

All steppers are fully functional and rotation tested.

The printer is defined using M667 K1, it is usind a Duet 3 and RRF 3 RC2.

@Garfield See https://duet3d.dozuki.com/Wiki/Gcode#Section_M667_Select_CoreXY_or_related_mode

[M667] is deprecated in RRF 2.03 and later. Use M669 instead.

If the config tool put M667 in, let me know.

M669 fixed the problem, and confirmed I wasn't going nuts ....

Much appreciated.

Some of the stuff kicked out by the configuation tool isn't so good - needs some work I think.

@Garfield said in Expectation fault or actual fault:

M667 K1

The configurator gave you M667 K1? M667 S1 would have still worked. M669 K1 is the newer format. Odd that it's a mix of new and old.

Just tested the configurator and when choosing Duet3 and rrf3 and corexy I got M667 S1 ; select CoreXY mode which is still valid.

[Garfield]

I changed the S1 to K1 because documentation said that S1 was obsolete - I need to go look where - I think it was in the place where the differences between V2 and V3 are detailed - I'll go see if I can find

[Garfield]

Well my bad I found the location - I read the K1 but failed to spot that 667 had changed to 669 so this is definitely a PICNIC problem

No worries. The configurator should probably be updated to use M669 now anyway.
