Check S-value max in Device Settings.
In the console check $30, $31 and $32
These are;
$30 - Max Spindle Speed and should match your S-value max in the Device Settings
$31 - Min Spindle Speed. Should be 0
$32 - Laser Mode. Should be 1
I do have a voltmeter, but im not sure how to use the thing. I will go watch some basics on you-tube. Can you give me an idea of test point locations I need to focus on? I know this sounds dumb but I am a newbie and don’t want to overlook anything stupid.
This is my laser module, you might have to find your to get some kind of reference for your laser module pinout.
Most of these have only three connections. Don’t worry about Temperature.
ground
power
pwm
Yours might or might not have the same pin out.
If you measure from ground to power you should read full supply voltage to the laser.
From ground to pwm, is a ttl signal (0 to 5V) that is used to fire the laser. When it goes high the laser turns on, when low it is off.
You don’t need the laser module powered up, so you can do this from the connector if you wish… For the PWM reading you need to send a job to the machine at a specific power percentage.
Don’t short any of these lines to any other.
With a voltmeter you can measure 50% pwm at about 1/2 of the 5V supply… The percentage power you send it will be a percentage of the 5V supply control. 20% is 1V… 60% would be about 3V… 50% is usually pretty easy.
If you have the supply voltage and a valid pwm, the laser should fire…
