@ignacmc @jay_s_uk @Phaedrux @T3P3Tony @dc42

FINAL Update: I have updated firmware from 3.4.5 to 3.5.0 beta 3 and the error no longer happens, so it definitely seemed to be a bug in 3.4.5!

BTW, My Duet3 Mini5+ is a FYSETC clone.

YIPEEEEE!!!!!

@dc42 David....you are a father to me! It did the trick...

Stupid me, I forgot I have made that change a few days ago while researching here how to tune Stealthchop and didn't print since then so I was not aware of the problem I had just created.

Today in Spain is the Fairy Kings day, when tradionally Christmas presents arrived. This has been a very nice one!

Thanks for your outstanding support!

@jay_s_uk Noted! I would like to know the experience of a BLTouch Delta Printer owner just for curiosity....

@dc42 Yes, Now I don't have any problem with G32. the sensivity was probably a typo of the guy who send me the config.g. Changed to 0.02 and now it runs perfect

@jay_s_uk Yes, I have been printing with these config files for months without issues. I suspect some hardware problem. As I was going to replace my LDO 0.9 motors for OMC equivalents, I will do it and recheck all wiring at the same time...

@jay_s_uk Think I will be getting one and ditching the NTC100K....I suppose it does not have any disadvantage over a thermistor even at low temps

@arnold_r_clark Thanks Arnold...your very clear explanation adds to jay's one...I think is time for getting another SmartEffector. Or doing fully manual calibration with the nozzle tip ignoring the inductive sensor...

@dc42 Thanks David. I will order them inmediately.
The fact is that I have a Duet 2 Wifi installed on the printer and a Duet3 Mini5+ waiting on my desk. Wondering if 2209 vs 2660 worth the effort to do the transplant....

@ibash Wow! Thank you very much for your detailed explanation. It exceeds my expectations and I believe it sets me in the right direction to tune my delta. By the way and seeing that LDO 0.9 seems to not get along very well with TMC2209, I have ordered 3 OMC 17HM19-2004S1 for replacing them...I will report with my findings

@bberger My idea is something like this:

I can send you the Fusion360 files if you want. I intend to place some steel tape on the towers and some embedded magnets or magnetic tape on the enclosure panels

@Phaedrux Everything worked fine after clearing the cache (Chrome browser)...Who could have Imagined? Now the input shaping appears as a "Integrated Plugin" instead of a "External Plugin". Upgraded to 3.5.1 without problems...

Thanks you very much. Learned something new today!

@chrishamm Hi Chris

I am in standalone mode. How to do the reload? I tried by reinstalling RRF 3.5.0. but it didn't solve the issue

@chrishamm Did it and rebooted but the same situation persists

Cannot uninstall or reinstall

@jay_s_uk Yes. I read it too late. How can I get rid of the old one? I does not allow me to uninstall it

I have just updated to RRF 3.5.0. Everything went right and after the update I tried to also update the plugins. "Endstops Monitor" and "Object Cancel" went just fine but Input Shaping get greyed out and deactivated

Now I have tried to reinstall plubing by uploading the corresponding zip file, but no matter if I try "InputShaping-3.4.7.zip" or "InputShaping-3.5.0-b1.zip" I got an error message like this:

What can I do? tried to reinstall whole RRF 3.5.0 but it didn't work

@dc42 Changing to another 2510 fan (Sunon brand) solved all problems. Who could have imagined? I shielded all cables in vain

@apak What is this? hahaha.... Any real printer or mod?

@apak I am not using magnetic arms. Made a design in Fusion 360 based on one very similar that found on Thingiverse and then had it printed in ALUMINUM in China. Made the M3 threads manually.

But thank you very much for this info that I will keep should i ever go the "magnetic way"

@dc42 Yes. I was happily living with a SmartEffector v2 + E3Dv6 and zero fan problemas when I decide to change the whole toolhead to something more actual: SmartEffector v4 + Bambulab clone:

Here the problems started.....

Curiously I was concerned about the heater cables being very close to the PCB, but it didn't seem to affect it at all

@dc42 I have just ordered different 2510 fans to see if I am lucky and they make a difference. Aternatives to GDSTIME for that size are not easy to find....

I have also thought of wrapping the fan case with a very thin nickel strip (the ones used for spot welding 18650 batteries...will try tonight and report

Configuration-wise....Is there something I could do by lowering the speed or changing PWM frequency? You tell me I will generate more magnetic field by running slower? Is this correct?
