[url][/url]Hi all
i try to explain what I need.
I try to control a co2 laser via UCCNC soft and hardware.
I use the UCBB breakout board with the UC 400 ETH
Everthing work fine except I cant get a propre PWM signal to control the power.
What I did , I took two outputs. 1 I use for sending the M3 signal to the power supply to say ok please start up your pcb power supply waits now for a signal of the PWM or manual with pot meter.
With potmeter I can control the power no problem but cant get the signal.
I used the second output from the BB but the problem (so far I think) is that all the outputs are NEGATIVE powered and the signal I need for the power supply is possitive.

This is a picture of the classic power supplies for CO2 laser.
Is there somebody who can point me in the correct direction.
Please dont talk to technical about electronics because I don't understand If I need special extra hardware please tell me.
Thanks already
