@oliof GRAZIE

Can anyone tell me why when I print any shape the internal part is narrower by about 8 tenths. I'll start by saying that the external part is perfect with an error of about 5 cents.
I wanted to point out that the prints are drawn at the pitch of the nozzle size

@chrishamm said in RFF3.42 display the extruder speed:

DWC 3.5.1
DWC 3.5.1 works of love to upgrade because I know there are a few things to replace I have the version 3.4.2
I'm not aware of how many things you'll then have to reset

@dc42 said in RFF3.42 display the extruder speed:

@paolozampini1973 RRF doesn't currently provide the instantaneous extrusion speed in the object model. I can look at adding that in RRF 3.5.

Currently the best you can do is to read move.extruders[n].position or move.extruders[n].rawPosition at intervals and calculate an average extrusion rate over the interval from the increase in value.

@dc42 Hi, do you remember I asked you two years ago to display the extrusion speed and you told me that you would insert it into the RF 3.5, did you do it then? Thanks

@oliof Thanks everyone for the information

@droftarts I also tried the other older plugins but the problem persists, the version I have, if you noticed, is the interprise; from the Street shot However, I repeat even with older versions of plugins and the problem remains

@dc42
I tried all the plugins but none of them work with version 5.3. How can you solve the problem, thanks

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

@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

GRAZIE

@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

@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

@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

@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

@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:

1. the metal heats up little
2. vibrations are very low
3. high precision
4. for most of the processes it requires very little lubrication and for other processes there is no need to lubricate
5. 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:
6. high current draw
7. below 1000 rpm very low torque and does not allow to do some machining especially at 200 RPM
8. 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 :

1. AXIS FOR CONTINUOUS USE MILLING (ROTATIVE) WHICH HAS THE SAME FUNCTION AS THE VFD
   LATHE:
2. 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
