I mean in the config.g file but as I mentioned I don't think this is a solution!

As T3P3Tony said there could be a tool change in the actual gcode.

Another problem could be that your customer set the temperatur for the first layer right but changed the temperatur of the other layers. I know this from the prusa slicer:

But then it doesn't make sense that the tool gets deaktivated...

Hi percar

Maybe this helps to fix your problem:

Hi there,
In fact you could run the mesh compensation with G29 S0 just once. After that the heightmap is saved. In your start gcode just then just need the command G29 S1 to load the saved heightmap. That's it, works perfect for me!
After some prints if you see that the compensation isn't perfect anymore you just run the mesh compensation again with G29 S0 and your good again.

@Nxt-1 You could use the existing screws on top of the motor to connect the ground with a connector like this:

Hi JV

Did you check if your disabled heater gets overwriten in the config-override.g file?

Hi there,

To move the tool just 10mm down from the actual printing position, you have to set the Z-axis with G91 to relativ movement instead of absolut. Then you can send a G1 Z10. After that you have to go back to absolut movement with G90. These three commands should be in the tfree#.g file of the RRF tool change files I guess.

I used both and will definitely stick with the Duet ABL!
The possibility to save a heightmap of your headbed alone is a big reason. This makes it possible to probe your bed just once and then load the saved heightmap before every print. Saves a lot of time and is much more convenient.
The ABL itself works great and stable, I can really recommend it.

Thanks a lot, I will try then!

Since there was no answer for a long time (and I was in holyday) I retry to find a solution for my problem. It would be a shame to trash such a nice board with just one component damaged...

Any chance that there is a solution to repair the board or tp get it replaced under warranty?

Best Markus

Did you test if enabling retraction reduces the amount of blobs or do you just assume that the blobs will get worse?
Because I could imagine retracting could prevent that too much plastic gets out of the nozzle after the print move finished and before the nozzle takes off to another location.

Another problem could be that your customer set the temperatur for the first layer right but changed the temperatur of the other layers. I know this from the prusa slicer:

But then it doesn't make sense that the tool gets deaktivated...

To change the standby temperatur of a tool you need to change the following code in the config.g file:

M563 P0 D0 H1 ; define tool 0
G10 P0 X0.0 Y0.0 Z0.0 R0 S215 ; offsets, active and standby temperatur

The R parameter is the standby temperatur and the S parameter the active temperatur.
But I don't think this is a solution.

Is it possible that your customer encounters some temperatur faults and there by the tool gets deactivated? If so there should appear an error message on the PanelDue or DuetWebControll.

Your welcom.

Yes a clogged nozzle with carbon filament = irreversible destroyed nozzle...

I don't know what filament brand you are using but I am printing with 245°C/75°C and print with the same printing speed as PLA.
It is importand that you have a hardend nozzle on your hoten!!

Hi Paul

Is it possible that your retractsettings are not right? Try a higher retract distanc to see if these blobs disappear.
I am printing a lot with colorfabbs XT-CF20 and don't have such imperfections. The right flowrate is also crucial for printing with carbon fiber materials. There has to be a slight overflow but not so much that it is visibel.
Here is one of my results with carbon filament:

EDIT: I have a extrusion multiplier of 1.2 and a retract length of 0.8mm with a E3D hotend.
