Just curious does the pwm outputs of the masso spindle control system if set to VFD still function. Do they output a pwm equal to the percentage of the 0-10V that would go to the normal VFD or are they not active unless the spindle control is set to PWM. Just curious as I use a VFD on my cnc and I'm looking at adding a laser engraver to it and using pwm from the ccw output would be useful.
Spindle control outputs
- Thread starter greevous
- Start date
That could be a winner (wonder what the pwm frequency of those are, had a look on ebay and none showed a frequency that they operated at), so keen to be able to run the system with a relatively simple way of converting from spindle to laser and back without complicated steps (my Dad uses the cnc for his projects so it can't be too complicated if I've forgotten to return it to spindle operation).
bought this laser (hope it lives up to it's advertising)

discussed it with them and they have added to their description that it will work with 0-5V ttl so can do a voltage divider, and the amperage for it to function is <1 mA to the TTL/PMW pin since it has its own driver circuit with seperate +12V and ground connections.

I just bought a laser module, and am actually feeling well atm. I am working on a small Arduino project that I think might be the answer just bring all spindle signals through a relay and use a m64 command to switch between laser and spindle so when command is issued the spindle gets relay signals to go off and convert analogue to pwm and what ever signals other signals it might need but maybe with a confirmation (I am using a very cheap oled to display spindle and laser parameters) turning off the m64 will revert back to standard spindle control it would be easy to put command into the gcode and give an automated way of control. I want to use laser for all sorts but for marking boards for attachment to spoil board etc and marking placement of parts would be very helpful. what do you guys think, it is simple to implement and means that the spindle has proper signals even when off
