Hi all, I’m trying to set up a laser using pins 11 and 14 controlling the Jtech 2.8 watt upgrade. I’m issuing the M03 and M05 commands using the macro function on UGS. When I do this, pin 11 only shows about 120 mili volts which goes down to 0 volts on an m05 command. Any ideas?
Thanks for getting back Justin. That command works! Can you tell me why it’s different to the M03 command? I guess I’ll have to edit all my Gcode to account for this do I?
Thanks ever so much for your help though.
So would you suggest that I get a newer GRBL version? I want to produce grey scale type work. Isn’t that where the pwm capability comes in? As you’ve probably guessed - I’m a complete novice…
You’ve made my evening - I’ve been on this all day!
