0-10V output is maxed at 2.25V

I am trying to use the 0-10V PWM to power an extra laser I had from the Febtop 3 in 1 machine and I send the m3 s command to give it full voltage and only get 2.25VDC. My 0-5V checks out at just over 5V.

Any ideas?

post your $$ output from grbl here.

Grbl 1.1f [’$’ for help]

$$
$0=10
$1=255
$2=0
$3=4
$4=0
$5=0
$6=0
$10=115
$11=0.020
$12=0.002
$13=0
$20=0
$21=0
$22=0
$23=3
$24=25.000
$25=750.000
$26=250
$27=1.000
$30=1000
$31=0
$32=0
$100=40.000
$101=40.000
$102=188.976
$110=8000.000
$111=8000.000
$112=500.000
$120=500.000
$121=500.000
$122=50.000
$130=790.000
$131=790.000
$132=100.000
ok

and changing 32=0 to 32=1 doesn’t change the output voltages

You are using grbl 1.1f for you laser work. I really don’t recommend that, but if you really want to run 1.1f you need to read this document.

I added a mosfet module that had a 12v output and it works now.

Thanks
