@Phaedrux I also changed the cure versions but nothing to do. Thanks

CURA 5.3 does not load the plugin
@Phaedrux Can anyone help me I installed cura 5.3 and I installed the 1.2.10 plugin but it tells me that it could not be loaded because it is not possible to configure it and I also tried 1.2.9 and I tried many older versions up to 1.2.4

@T3P3Tony said in instant extruder speed:
@paolozampini1973 unfortunately not, this display relies on information from the newer firmware.
OK

@droftarts said in instant extruder speed:
@paolozampini1973 It has been added to RRF, I think it is this: https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x-Beta#reprapfirmware-350beta1
Added floating point field move.currentMove.extrusionRate (returns the current total extrusion rate in mm/sec)
We are testing internally a version of DWC 3.5b1 that shows volumetric flow:
But you should be able to see it through the Object Model.
Ian
it is possible to have only the upgrade of the instantaneous volumetric part of the extruder and without upgrading all the firmware because I don't want to have problems and by the way everything works fine now

@Phaedrux said in instant extruder speed:
@paolozampini1973 It is available now.
https://github.com/Duet3D/RepRapFirmware/releases/tag/3.5.0beta1
Thanks for the information. Here I understand that the instantaneous extruder velocity function has not been added as @dc42 said

@dc42 said in instant extruder speed:
@paolozampini1973 I hope to release 3.5beta1 next week. It's currently in the testing and bug fixing phase.
Good morning when will firmware version firmware 3.5beta1 be available ?

@oliof said in Spindle nema 34 duet 2 wifi:
@paolozampini1973 Duet2Wifi will not be able to fit new features due to space constraints.
thanks for the answer can it be clearer please Thanks

RE: UPDATE VFD TO NEMA
@jay_s_uk said in UPDATE VFD TO NEMA:
@paolozampini1973 what @Falcounet said. And the firmware doesn't support continuous rotational axis. And you can't move an axis that isn't in sync with others
Thanks for your answer

RE: Spindle nema 34 duet 2 wifi
@dc42 said in Spindle nema 34 duet 2 wifi:
@paolozampini1973 @CNCModeller if there is enough interest then I can look at providing the option to run a stepper motor as a spindle in a future version of RRF. However, it's likely to be a Duet 3 feature only because of lack of flash memory on Duet 2.
reading on the forum I saw that there are people particularly interested in the DUET 2 WiFi As for removing plastics with a cutter, I have a lot of experience and also with turning, over time I have understood that high speed has many disadvantages It is better to work at low speed with some strategies you can achieve excellent results without lengthening the times excessively

RE: Spindle nema 34 duet 2 wifi
@dc42 said in Spindle nema 34 duet 2 wifi:
Will a stepper motor provide sufficient speed and torque? Stepper motors are limited to a few revs/second due to back emf.
the stepper motor provides high torque at low revs which the vfd motor does not and this brings many advantages for my experience that I have done some technical tests
-
RE: Spindle nema 34 duet 2 wifi
@dc42 @CNCModeller @jay_s_uk
a stepper motor can reach 3200 RPM WITHOUT step loss tests done by me personally (nema 17 , 23 , 34 ) and as we know the advantage is the maximum torque at under 500 - 800 rpm and working on the export of materials at low speed leads only advantages because:- the metal heats up little
- vibrations are very low
- high precision
- for most of the processes it requires very little lubrication and for other processes there is no need to lubricate
- working plastic parts at 200 RPM they work very well having a high torque
VFD motors WORK from 0-22000 RPM i ne or 2 types example: a 3kw at 50 Newton +or- and a 1,5kw disadvantages: - high current draw
- below 1000 rpm very low torque and does not allow to do some machining especially at 200 RPM
- it takes a lot of lubrication I'LL STOP HERE BECAUSE THERE'S SO MUCH MORE TO SAY ABOUT THE DISADVANTAGES
I CLOSE BY SAYING THAT THE LOW SPEED IS THE BEST IN THE END EVEN IF THE PROCESSING TIMES LONGER
OR I READ THAT THERE ARE NUMEROUS PEOPLE INTERESTED
I ASK TO ADD TO @DC42 THE FOLLOWING FUNCTIONSIN DUET 2 WIFI, IN ME THE MOST SUITABLE:
MILL :- AXIS FOR CONTINUOUS USE MILLING (ROTATIVE) WHICH HAS THE SAME FUNCTION AS THE VFD
LATHE: - A OR B OR C AXIS FOR THREADING AND TURNING
I'M SORRY IF I WAS LITTLE SYNTHETIC IN THE EXPLANATIONS AND THANK YOU EVERYONE FOR PARTICIPATING
@DC42 I WOULD LIKE TO HELP

@JoergS5 said in Spindle nema 34 duet 2 wifi:
@paolozampini1973 no, no, I don't mean that you do it, but one of the developers of RepRapFirmware. I meant this with wishlist: there is a list somewhere what features are wished to be added to future versions.
A simple requirement, a single continuous axis without synchronization, which is useful for many users have a much higher chance to be implemented than the other ideas I wrote.
now i understand in the function wishlist But where is this list where you have to make the request?

FreeRTOS
thanks for the answer But honestly I don't want to start writing a program to make a function that in my opinion was a very very very simple function

RE: Spindle nema 34 duet 2 wifi
@dc42
firmware from what I understood from the various posts it seems that it is not possible to have with a stepper motor the same functionalities of the vfd motor because the firmware cannot handle it is it possible to implement this function please -
RE: Spindle nema 34 duet 2 wifi
@JoergS5 said in Spindle nema 34 duet 2 wifi:
Firmware organizes all axis movements in time frames (X moves n mm in 0.1 seconds, Y m mm in the same time etc.). A continuous movement doesn't have a time frame (because it's infinity time), so it's a problem.
A solution could be to add a separate FreeRTOS task which makes the continuous movement for a (stepper-)motor by generating own stepper signals without any time frame planning. It would run isolated from all other movements, but this needs to be added to the firmware, something for the wishlist.
thank you

@droftarts said in Spindle nema 34 duet 2 wifi:
such a 'spindle' mode for stepper drivers could be added to the firmware wishlist?
yesI believe, we've asked infinite rotation as FW feature before.
But there was a good reason, why it's complicated to implement. Can't describe it with my own words. Brain is frozen -
RE: UPDATE VFD TO NEMA
@jay_s_uk
why is it not possible on the lathe is it possible instead for milling is it not possible ? -
UPDATE VFD TO NEMA
I would like to have THE SAME FUNCTIONALITY OF THE VFD SPINDLE WITH A STEPPING MOTOR (NEMA) HOW SHOULD I CONFIGURE DUET 2 WIFI ?

@dc42 Good evening, I wanted to have some updates on the firmware for the instantaneous speed of the extruder
