@dc42 @chrishamm @T3P3Tony and the whole Duet3D Team! Thank you!
3.5.2 Closed loop SBC Setup Duet3 6HC 2x 1HCL with Magnetic Encoder on NEMA 17 1.8° LDO Motor
I have the Closed Loop System running for a week now and have been printing continuously 24/7 on a job that I had to abort six times before. Without the Closed Loop System, I would not be able to print the job!
Thanks a lot for this! After initial difficulties in tuning the system, because the instructions were written for quadrature shaft encoders, I was able to achieve a high-performance tuning. The Closed Loop System even has a better print quality e.g. because the backlash is compensated. I can run the steppers at full current, higher accelerations, higher speeds and the steppers are even cooler.
Btw. the printer is loosing the position about every 15 minutes on that print, due to the material. It's our PA6 CF HT which is very stiff and strong, so even the smallest amount of residues will stop/crash the print head. The print takes around 5.5 kg, where the material is around 89€/kg.
Please find attached a picture in which you can hardly see the misalignments.
Chris, after the hard work you put in the SBC setup it runs pretty stable now not rock solid, as I can still crash it - but mostly solid
Keep up the great work!
