Thanks for your reply but the command is not supported

@paolozampini1973 from my original post:

I think you can do that in RRF 3.4.0 by pretending that the fan is a motor brake solenoid.

so i should upgrade
The problem is that with my configuration I don't know what it means to me at What problems do I run into after what changes I have to make

am have RRF 3.3.0

my 3D printer now works very well however if I do the upgrade What are the changes I have to do next ?

@paolozampini1973 read the upgrade notes and make any required updates to your configuration: https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x#reprapfirmware-340

Other than adding macros for heater fault I did not change a single thing on my machine, but yours is different and may need adjusting.

Ok I will read And anyway I will make a complete backup of the memory in case I should have problems I can go back

oliof

@paolozampini1973 backups are always a good idea. I have my configurations under version control and stored on github for easy reference and to make sure that in the case of local catastrophe I have a copy available elsewhere.

I'll probably do this upgrade tomorrow as temperatures and speeds improve what your opinion is ?

I am running my printers very conservatively, so I do not go for maximum speed.

I believe that a printer once that makes 70 - 80 mm is more than enough important to have the accuracy is the quality

Ultimaker Cura Enterprise 4.10.0 I don't know if you've ever tried it but the prints are much higher quality and the processing takes about 20% less

paolozampini1973

@oliof I wanted to ask you but there is an algorithmic auto for temperatures because I don't like the one I have at all I would like that there would be an algorithmic auto that, based on the temperature that rises and falls, the rule automatically

oliof

I don't fully understand your request. Is this still about the fan to cool the stepper, or some other issue?

M307 H1 R2.300 C135.000:111.161 D12.60 S1.00 V25.0 B0 I0
I do not speak the regulation of the nozzle temperature I now have an algorithm that I created that is stable but when I suddenly increase the speed the temperature drops by 2 degrees even by degrees

paolozampini1973

@oliof temperature excursion exceeded 15.0°C this parameter can be changed instead of 15 degrees to have 20 degrees ?

@paolozampini1973 after you update to 3.4, you can try heater feedforward https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m309-set-or-report-heater-feedforward which raises the heater power for higher speed prints.
Alternately you can adjust the heater fault detection using M570 https://docs.duet3d.com/User_manual/Reference/Gcodes#m570-configure-heater-fault-detection but since this is a critical safety feature I would only use this as a last resort. It does allow you to adjust the excursion limit as you requested.
