Extruder calibration problem

@boxprinter said in Extruder calibration problem:

Unless you have very specific reason, you should stick with x16 with interpolation.

Thank you very much for your answers!
I don't know why but my Slicer settings were set to 2.85 mm filaments instead of 1.75 mm......
Now my calculation is a good approximation. I only have to fine tune the feed rate.

@droftarts I am using Cura, but not yet the latest version. I will check what you suggested.

@Veti OK, but why? I will try it nevertheless because I now have the problem that the printer stops moving during a print and does not react any more. With M122 I got:
Tasks: NETWORK(ready,456) HEAT(blocked,1136) CanReceiv(suspended,3804) CanSender(suspended,1472) CanClock(blocked,1416) TMC(blocked,72) MAIN(running,3468) IDLE(ready,200)
So the Duet thinks the nozzle is clogged? Is this the reason why to use x16 for the extruder?

if you have set all drivers to 256 microstepping you are overloading the cpu

@droftarts Maybo not so important any more since the changes:

FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC v0.6 or 1.0 FIRMWARE_VERSION: 3.0beta12 ELECTRONICS: Duet 3 MB6HC FIRMWARE_DATE: 2019-11-02b1

But I know that I schould update the firmware. I just finished the cabeling today.

@Veti Would x128 for XY, x64 for Z and x16 for E be ok? Say for ~ 120 mm/s

Veti

start with x16 and interpolation.
once you have your printer up and running, then you can experiment with other values.

you should update to 3.1.1
Beta firmwares are not supported anymore after the final release

boxprinter

@Veti Unfortunately I do not seem to be able to update via the Web interface.
Under Settings, I upload the new binary file and I get asked if I want to update.
Then this message appears:

M997 S0 Firmware binary "Duet3Firmware_MB6HC.bin" not found

But when I go to the System Editor Tab I can clearly see the file.

Veti

just upload this zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2and3Firmware-3.1.1.zip

boxprinter

It did not work either.

Veti

@boxprinter

you might have to go to 3.0 first
try uploading
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet3iap_sd_MB6HC.bin
and then upload
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet3Firmware_MB6HC.bin

and then try 3.1.1 again

boxprinter

Unfortunately also nothing. Should I try the USB methode?

Veti

@boxprinter

yes probably easiest to do the bossa restore

This came to late, I already upgraded via Bossa.

Everything seems to be ok now with the exception, that my PanelDue 5i does not communicate with the Duet 3 any more. I thus also updated it with Bossa from v1.23.2 to v1.24 but it stil does not work.

The paneldue baud rate will need to be defined in config.g M575 P1 B57600 S1

boxprinter

Thanks!
Is there any possibility to choose which four macros are displayed on the control page?

Phaedrux

Yes. Macros in the root of the Macros folder will show up in the short list of 4 on the PanelDue. You can use a prefix number to sort them how you wish.

Ex:

0_preheat
1_center nozzle
2_turn heaters off
3_etc etc

the prefix will then be hidden.
