Is there maybe some tool that can convert PostProcessor from Fusion360 to CamWorks? This could also be helpful.

Thank you

Hi,
Any idea where can I find PostProcessor for Duet firmware 3+ for SolidWorks (CAMWorks)?
I have tried using grbl postprocessor, but it has no G, M, T in front of every line, so it's pretty much unusable.

Thanks in advance for any suggestion!

Best regards

Hi,
I tried 3.2beta2 on Duet3 with Rpi but nothing really works for me. I was unable to make a print, the Z axis moves very slowly, and the start of the print is not done correctly. The head and the bed seem to go their own way .... until the bed hits the head.

I am running Duet 3 on a CNC machine, and I have observed similar behavior exactly after updating firmware. Any idea why is this happening?

Btw, thank you for instructions how to downgrade. Now it's working just fine!

Best regards

You could try sending the command via the PanelDue serial port. Caution: it uses 3.3V signal levels; 5V will damage the MCU.

Duet 3 Hardware Overview web page says: "The inputs will tolerate up to 30V. The outputs are 3.3V signals levels with 470R series resistors."

I would like to know how can you damage MCU with 5V if input is tolerating up to 30V?

Best regards

I stand corrected. On Duet 3, PanelDue connects to the IO_0 connector, which is indeed tolerant of 30V on the input pin. On Duet 2 and Duet 085 it tolerates 3.3V maximum.

Thank you!

@radiomodell said in [3.01-RC10][Duet6HC] Spindle pwm 10-90%:

Thank you for your answers!!!

As dc42 sayed, it is no good idea to run spindle from config.g

I have no intentions to run spindle from config.g. It was only a suggestion to set pwm output to some minimum % in config.g and then spindle would have been controlled later by g-code (by turning on digital outputs, and setting new values for pwm).

Escon 50/5 is Maxxon Brand? If yes, did you try ESCON -Studio software to reconfigure board not to raise an error under 10% PWM when spindle is switched off?
I used EPOS-Studio to configure similar motion control devices. Each I/O was freely configurable.

Yes! I have used ESCON-Studio software to configure spindle, but I can't seem to find where to disable error if pwm is under 10%? Although, by later examination I think this error is reset upon setting enable signal high. Not sure 100%.

If you want to follow your solution,I would try to define "out9" as standard I/O pin, eg. P0, and assign a PWM value with M42 command.

Ok. I would have to modify post-processor for this, but not a big deal.

From my experience in CNC-Mode this is used for DWC Tool display only.

Yes. This was the original intention for this line, to be able to see spindle rpm on DWC.

M453 S0 C"out6+out7" T0 ; set machine to CNC mode with out6 for CW and out7 for CCW spindle signal

A M3 S255 command would output 100% PWM signal at "out6" , a M4 S127 commad 50% at "out7" simultaniously setting "out6" to 0%.

Ok, I have misunderstood g-code explanation completely on this one. Thank you for clarification.

Thank you again for clarification!
Best regards!

@dc42
Hey, I appreciate your product and everything you have done for Duet.

But, please, you don't have to answer forum questions if you don't have a good answer, just so you can mark them as "answered". You haven't even read my question, then you have sent some reply that is not helpful at all. And then you ignored my follow-up question.
Please, try to act more professionally.

Other users, if anyone can help me with this, I would very much appreciate your help.

Best regards

But, M3 will also trigger CW enable output? I would like just to set pwm not to turn on spindle.

Thank you for any suggestion.

Hi,
I was looking through g-codes, but I am not really sure my logic is ok for how to set spindle pwm to be 10% at machine start.

My spindle VFD is Escon50/5 board that requires three digital inputs: one pwm for spindle speed, and other two for spindle CW/CCW enable signal. VFD requires pwm input to be between 10-90% at all times, otherwise reports an error.

This is my spindle configuration in config.g:
M950 F0 C"out9" Q100 ; create Spindle control output as Fan0 on pin out9
M563 P0 S"Spindle" F0 ; define tool 0 - Spindle, use fan F0
M453 S0 C"out6+out7" T0 ; set machine to CNC mode with out6 for CW and out7 for CCW spindle signal

Provided that this configuration is ok, can I use M106 to set default PWM value in config.g?

Thank you in advance!
