Laser power allways near 100%

[throbulator01]

Trying to get grblhal working on an esp32 with lightburn. The pwm output at 1% laser power does about 3.2 volts which is way too high. Ive tried fluid nc and that operates as expected.

Machine settings:

$$ $0=10.0 $1=25 $2=0 $3=0 $4=7 $5=0 $6=0 $9=1 $10=511 $11=0.010 $12=0.002 $13=0 $14=0 $15=0 $16=0 $17=0 $18=0 $19=0 $20=0 $21=0 $22=0 $23=0 $24=25.0 $25=500.0 $26=250 $27=1.000 $28=0.100 $29=0.0 $30=1000.000 $31=0.000 $32=1 $33=1000.0 $34=0.0 $35=0.0 $36=100.0 $37=0 $39=1 $40=0 $43=1 $44=4 $45=3 $46=0 $62=0 $63=3 $64=0 $65=0 $100=100.000 $101=100.000 $102=250.000 $110=10000.000 $111=10000.000 $112=500.000 $120=600.000 $121=600.000 $122=10.000 $130=200.000 $131=200.000 $132=200.000 $341=0 $342=30.0 $343=25.0 $344=200.0 $345=200.0 $346=1 $384=0 $398=35 $481=0

using the esp32 master driver im a little over my head in this whole thing. Im running an old nano shield with jumpers in the right slots. Everything ive researched indicates it should be correctly configured.

Which board map? And which version (output from $I)? My test board is working fine, even with 1000 Hz PWM ($30) which is, IMO, on the low end for lasers.

I set it to the bdring v4 map. Im really not sure what you mean by the $I output for the version sorry im not rly a programmer im just figuring it out as i go.

i just tried it a little earlier with fluidnc and i changed the pin mappings to imitate the bdring mappings and laser control was as it should be.

Also the first time i tried i used the generic mappings file and i couldnt get the laser to fire at all, could it be that the mapping file somehow points the firmware to a different control mechanism for the laser and I should use a different mapping profile to imitate a generic style laser pwm?

omg nvm i made a mistake, i had enable laser and pwm control pins mixed up :/ user error sorry for the disruption. Thanks for your time!!!!
