Problem with X axis going to side and extruder moving too fast

[Duncan]

Hello!
I was working good but suddenly my printer starts doing strange things... I have a Duet 3 Mainboard 6HC with a Toolboard and usually (the printer is big, 1x1x1 meters) I'm not in front of it and don't have a camera recording, only one to see if something goes wrong...

I've been having problems last week and today, I saw that while it was printing the X axis goes suddenly to the top right while extruder is doing a lot of noise like retracting fully... then it goes back to where it was printing and continue... but this is repetidly doing sometimes until the hotend is blocked because of it....

I cleaned all the board, I put a new SD card..., but problem persists... I really don't know what is the problem... it was printing really good and with no changes it's doing it now...

Any help?

Thank you

Firmware version?

[droftarts]

@Duncan If nothing has changed on the printer, and these are new print jobs, I'd suspect a change in your slicer settings. Try printing an old job that you know works correctly.

If you have changed something, eg configuration or wiring, look at what you have changed.

Unfortunately, you haven't provided much information, so it's hard to diagnose. For what information to provide, see https://forum.duet3d.com/topic/5909/guide-for-posting-requests-for-help. Ideally, config.g and M122 report, as a minimum.

Sorry for the missing information.

I haven't change anything, even slicer software is the same and old files are working wrong also.

Firmware version is 3.4.0. in a Duet 3 Mainboard 6HC with Toolboard 1LC with the hotend, extruder and 3D-Touch probe connected.

It's a cartesian printer.

Tomorrow I'll go to the place I have the printer and will upload config.cfg and M122 report.

The strange thing for me is that I was printing a lot of huge parts for a couple weeks... I change filament and put an old file again to print and starts failing suddenly.

I think tomorrow I will update firmware, what do you recommend? go for latest stable 3.5.4 or the last 3.6 RC3?

@Duncan said in Problem with X axis going to side and extruder moving too fast:

go for latest stable 3.5.4 or the last 3.6 RC3?

I'd start with 3.5.4 and see if anything changes for you. 3.6 final won't be too long now.

Hello,

this is my config and M122 results.

Anyway, I'm going to update now and test

Hello again,

I updated to 3.5.4, it seems to be all working but I'm trying to make the mesh for the bed with the tool and when I hit the option to start the mesh with G29

The printer moves really slow... like 0,5mm/sec, and I can't find where is the problem, because normal moves are ok, homing is ok and when I use G30 is also ok...

My new config.g is this:

@Duncan slow movement is usually caused by the slice rinserting M201 and/or M203 commands into the GCode file. Configure your slicer not to do this. It is totally unnecessary for slicers to insert these commands because there are other parameters and commands to set speeds and accelerations for one particular print.

[Duncan]

@dc42 thank you, I located my mistake... the speed in M558 was T100 by default and I didn't change it... I put 10000 and now it's doing the mesh leveling.

After that I will try to print again my old files and see if the problem I was creating this thread about it's still existing or not.

Thank you!

[Duncan]

Hello,

I still have the problem, after update, change SD... no idea what's the problem... still going to the right and extruder moving so fast while it goes and return to print...

[droftarts]

@Duncan I'd think that some Gcode is being sent from somewhere, if the job is interrupted with this strange movement, but then returns to where it was after the interruption, without losing position.

I think you have a PanelDue connected? Try disconnecting that, and see if the printer runs correctly. It's possible the cable between the Duet and PanelDue is picking up interference, or something is pressing on the screen of the PanelDue and triggering a macro. What firmware version are you running on the PanelDue? Check the 'Setup' screen on the PanelDue.

[Duncan]

@droftarts Hello!
My paneldue was in 3.4.0, just updated to latest firmware.

I updated also Orca Slicer and I'm doing again the gcode files.

Also I recheck all wires and try to avoid any interferences between data and power...

So let's try again.

Thank you!

[Duncan]

Hello!
Last part was printed ok, so I put another one this morning and hope nothing fails again...

It's very strange because I really don't know what is or was the real problem...

Because of the updates I notice that the Tool 0 is not activated on power up and I have to press the "toolzero" in browser...

My last config.g is on my previous post... the line to activate the T0 is

M568 P0 R0 S0 ; set initial tool #0 active and standby temperatures to 0C

I also tried with the old line on my previous config.g

G10 P0 R0 S0 ; set initial tool #0 active and standby temperatures to 0C

But problem is the same... any ideas?

[fcwilt]

@Duncan

To activate tool zero you need a T0 command - you can put it after the other tool commands in config.g if you want.
