Do you have a voltmeter?
It’s much more difficult to help you if you don’t answer our questions.
sorry i did see the message. hand held yes but not on the machine
No need for a voltmeter on the machine.
The IN or the Ruida LPWM1 output will read a percentage set on the layer. The ttl signal is 5V, a 50% pwm will read 2.5V at 20% it will read 1 volt…
The laser is fired by the L input going low… Both of these can be measured with your voltmeter…
Just tried to upload a short video of the material test but it won’t allow me to send to you
Post it on something like Google drives and post a link… You can’t upload anything over 4MB…
I will have a look tomorrow as I’m off to the dr’s soon.
Well, at least I am working ish. Thank you so much. deeply grateful of your time
Ian
