SmartBOB controllers and dedicated accessories / PMDX-424 PWM control for Laser
« on: February 15, 2020, 03:07:07 PM »
I have been using my 424 on my CNC for about a year now. I am trying to add a laser. The 7w laser has red, black, yellow. Red and Black are for 12v and the yellow is PWM.
I clone my Mach4 profile and created a laser profile so not to mess with router profile
Can the 424 control the pwm thru output 1 without a breakout board? If so, what are the correct settings in Mach4 and the plugin?
I have Mach4 spindle 0 min 0 max 100 feedback 1.00
on the plugin I have selected Spindle - pwm Output 1 and told it to report Estimate RPM from pwm/pulse frequency.
I measure with a meter on the 424 output 1 voltage is almost 5V. It doesn't change at all when I slide the spindle speed up or down. And on the machine diagnostic window, it shows 0 true rpm no matter where the slider is.
I feel like I have missed something in the Mach4 setup not telling the PDMX-424 to control spindle. (Perhaps on the output signals tab)
What else do I need to do?
Many Thanks
Tripp
