@markz Thank you!

Is it possible to us the 'out6_buff' to fire a TTL CO2 Laser? We are currently trying to control an 45 watt TTL CO2 Laser using a Cloudray MYJG50W Power Supply using a Duet 3 Mini5+ Control board.

On the Cloudray MYJG50W power supply, the 'L' pin is a digital on/off >3 Vdc = OFF and less than .3 Vdc = ON. The 'IN' pin is the analog PMW signal.

We are ABLE to fire the laser using the 'out6_buff' pin on the Duet 3 Mini +5 control board when we wire the 'out6_buff' to the L pin on the MYJG50W.

We are NOT ABLE to fire the laser using the 'output6.buff" pin on the Duet 3 mini 5+when we wire to the IN pin on the MYJG5W. The 'L' pin on the MYJG50W is a Digital TTL on/off and the 'IN' pin is a analog 0-5vdc analog PMW signal.

Since the 45 watt CO2 laser that we are using TTL logic, I had to use a '!" to invert the output in the config. g file in the program to fire the Laser on TTL low.

; Tools
M563 P1 S"Laser" F0 ; define tool 1 Laser
G10 P1 X0 Y0 Z0 ; set tool 1 axis offsetsC
G10 P1 R0 S0 ; set initial tool 1 active and standby power to 0
M452 C"!out6" R255 S0 F3000 ; enable Laser mode, on out6 (F3000)

I'm not sure if this is a programming issue or a wiring Issue. Any advice to resolve the issue will be greatly appreciated.

@infiniteloop Thank you so much!

G93 was working, but now it isn't. I did update to 3.4.6 and now G93 doesn't work.
Thinking that the update made it unsupported, I went back to 3.4.5, still doesn't work. Went back to 3.4.0, still doesn't work.

Why was G93 supported, but now it isn't?
Does any mode support it?

Thank you

@dc42 Thank you so much

@dc42 Thank you!
I switched to the NPN NO sensor.
Am I still able to use this in the IO_3? Connecting the ground to the IO_3 GND, the power to 12/24v supply, and the signal to IO_3 IN? Still using the same config? M574 A1 S1 P"!io3.in"?

TIA

I have a Duet3 mini5+, using a PNP NC proximity sensor currently using the IO_3.in using the 5V_EXT, GND and IN pin.
The sensor has a light that is lit when not sensing anything and 5V is read from this. When sensing, the light goes out and it goes to 0V.
My config for it is M574 A1 S1 P"!io3.in".
The axis rotates according to the homea.g file, but never stops at switch.

I've searched for an answer but have not found any.

Anyone have any ideas as to why it isn't stopping at the home switch?

@dc42 Thank you!

I have a laser that has a frequency from 0-20khz. Is there any limitations from the duet3 mini5+ board that would keep me from using the full 20khz?

@markz Thank you!

I am thinking about getting the Duet3 6XD and I'm wanting to know what kind of software is needed?
The software I'm looking for is going to be similar to Mach3 or Mach4 or something like LaserGRBL, software that can be loaded with custom g-code and be executed. Thank you.
