@crpalmer There is a feature request for offsetting one individual endstop when using dual endstops. https://github.com/Duet3D/RepRapFirmware/issues/627

Ian

T3P3 created this issue in Duet3D/RepRapFirmware open Different endstop position for each driver in an axis #627

@mirellehgf said in Need Advice on Tuning PID for a Hotend on Duet 2 WiFi:

the temperature fluctuates slightly during longer prints- usually by about 2-3°C.

In what way does it fluctuate? If it is a regular oscillation then you can fix that by increasing the D parameter in the M307 command.

@jay_s_uk ok that got me there. don't know how that happened as i upgraded cura but didnt change anything there and it had been working perfectly

Thanks for your help

I found another article on setting up the DSF software and found that there is a reference to gpiochip4 in the file /opt/dsf/conf/config.json, editing the value of of following line resolved the issue:

"GpioChipDevice": "/dev/gpiochip4",

Changing this to /dev/gpiochip0 and restarting resolved the issue and I can now access the web interface.

@SPAX thanks for your report.

TBH although it appears that there is a bug in this area, we might not fix it for the following reasons:

Input shaping has been completely reimplemented 3.6 than in 3.5 and works much better. We have no reports of a similar bug in 3.6. It's likely that tracking this bug down would require substantial effort, which ultimately would be wasted because the 3.6 code is completely different. Delta printers typically have little or no need for input shaping because their resonant frequencies tend to be higher.

Of course, if anyone else tracks this down and supplies a fix that we can validate, we will gladly include it in a future 3.5.x release.

If you are brave enough then I suggest you try RRF 3.6.0-alpha.5 on your machine. Or you can wait for 3.6.0-beta.1 which I estimate is 2 weeks away.

The volumetric flow rate shown by DWC is the commanded flow rate before pressure advance or nonlinear extrusion is applied. Pressure advance only changes the commanded flow rate during acceleration and deceleration. For the steady speed part of a long move the volumetric flow rate should be the same as the value implied by the GCode command and the nozzle diameter, provided that the actual speed matches the requested speed.

One way to check the calibration of nonlinear extrusion is to use the Duet3D Magnetic Filament Monitor (or the MFM add on to the Roto Tool board) to compare actual vs commanded extrusion during a sequence of long straight moves executed at various speeds and corresponding flow rates.

@droftarts so here's my code after making the changes: (this is 3.5.3-rc.1 in standalone mode)

This all works and the brakes keep working. But if I unmap the brakes and re-map the brakes, or remap the drive that uses brakes to a different axis, the brakes... break. The only way to get them to work again is to reboot.

Also on the M569.7 command, if the S parameter is too high, it causes SPI issues in the DWC console.

@mirellehgf
Hi and welcome!

@Esteban Glad you fixed it. I updated your first post with translation and corrected links, and was about to look through your config to see what it was doing, so thank you for saving my time!

@dc42 said in Modify Panel-due:

@R006 https://github.com/Duet3D/PanelDueFirmware

Thank you!
Could you please guide me on which file I need to modify to apply these changes?

@Bridge-Of-Don said in Sporadic Temperature Changes:

We took the multi plug fitted at the themister apart and one of the two connectors just 'fell-out' and no real force to push back in, so hopefully that was the issue, only time will tell!?

Alan

Well several prints later and the temperature does seem to be 'rock steady' so another of the teething problems crossed off the list!! 😁

and all who are so inclined can now use Manyfold to host their own model repo and federate with others if they want

https://manyfold.app/news/2024/09/04/release-v0-77-0.html

@mike_b having the same issue in sbc mode. I wish there were instructions to manually upload firmware in sbc mode, instead of using M997.

@mikeabuilder Thanks 🙏

OK, the printer has won. I will rebuild the endstop. The Y homing works perfectly when the printer lays on its side. It miss behaves as soon as it is back on its feed. I think that the microswitch has a problem. Case closed, back to the workshop.

@Phaedrux That's exactly what I was thinking. I need some exaggeration. Thanks for the help. I'll get back with ya!

@Phaedrux Problem solved. Dont know why, seems chromium got bloques as usual when changing the printers fantasy name. Usually when this hapenned in the past, using this link on desktop asked you about a lock being present and giving you the chance to reset this lok. This time that never happened.

Manually removing the lock solved the problem:

rm .config/chromium/SingletonLock

Thaks

I rebuild the toolhead including the extruder and it seems to me like the problem is gone now. I will do some more test prints but I think that we can close the problem now.

Cheers, Chriss

@crpalmer if using the TOOL1LC then you should use the E3D converter. The TOOL1RR board for the Revo Roto extruder can drive the 5V fan directly.
