Strange bugs 3.3beta2

[Dep]

Errors periodically pop up like in the screenshots:

I didn’t notice this before.

Also tell me when mesh compensation is on, should the bed move when moving along the axis?

The unevenness of the table is about 0.5 mm, mesh compensation is on, I move the printer head (by PanelDue) and there is no movement of the Z motors.

Thanks.

@Dep thats generally interference in the cable for the paneldue. how long is the paneldue cable, what type of cable is it and does it run past any motors etc?

[Dep]

Good idea! Thanks, I'll fix it.

The wire is long, it does not pass near others, but nevertheless it must be made with shielding!

All the same, what about the movement along the axes with mesh compensation enabled? Should the bed move?

Which Duet?

Have you confirmed using M115 that you really do have RRF 3.3beta2 running?

[Dep]

@dc42 Duet 3 MB6HC (MB6HC)

Yes:

The command N1912 M409 F"d99f" is valid, although I am surprised that there is no K parameter. Also the N1912 prefix would not normally be included in a "Bad command" message. So I suspect that the command actually contains a non-printing character right at the start. This could be caused by interference pickup, especially if the PanelDue cable runs close to a stepper motor cable.

[dc42]

The messages about M4 commands probably mean that the zero in M409 was corrupted.

What M575 P1 line do you have in config.g ?

[Dep]

@dc42 said in Strange bugs 3.3beta2:

PanelDue

PanelDue cable does not run near motors. But I will do it differently.

could you answer my question about the movement along the axes with mesh compensation enabled? Should the bed move?

I just can't figure it out.

@Dep said in Strange bugs 3.3beta2:

could you answer my question about the movement along the axes with mesh compensation enabled? Should the bed move?

Yes, but it's hard to see whether the Z motors are moving a little or not on most printers. For example, with 400 Z steps/mm @ x16 microstepping on 1.8deg motors, the leadscrews will turn only 1/10 turn for 0.4mm movement.

[Dep]

@dc42 In fact of the matter. I attached a long stick to the pulley. There is no movement and no sound.

And during printing, the compensation does not work.

[dc42]

Run M122 and check that it reports "Bed compensation in use: mesh" while it is printing.

[Dep]

@dc42
I usually do that.

The size of the table at the printer is 1x1 meter. And the unevenness is about 0.5mm. I usually see the Z motors move.

Should I try to install an older firmware? Or does everything work for you?

[Dep]

Another dangerous bug!

M558 K0 H5 A5 F120
Works as it should

M558 K0 H5 A5 F120: 120
Also works as it should

M558 K0 H5 A5 F120: 60
Broke today probe.
The bed goes up and breaks the probe. And continue to rise.

I checked it several times.

[Phaedrux]

@Dep said in Strange bugs 3.3beta2:

M558 K0 H5 A5 F120: 60
Broke today probe.

Why would you use F120: 60 at all?

To better understand why the mesh isn't moving the Z axis please provide your config.g and homing files so we can see what other commands are taking affect.

[Dep]

@Phaedrux thanks!

M98 P"/macros/Move/bed_level_points"

What's in that macro?

@Dep said in Strange bugs 3.3beta2:

M98 P"homex.g" M98 P"homey.g"

Can you share these as well?

Can you also share the results of sending M98 P"config.g" and share your slicer start gcode.
