I appologize for the confusion when I think hardware PWM, I think in addition to current hardware, something else that I have to add to get the desired results. this is going to sound silly, but this isn't cut and paste in driver.h is it I need to m…

"I did some digging and I found this "marlin uses 490 hz PWM to control laser grey-scale" "Pwm,phase correct" I tried first on pin 58 on a ramps 1.4 didn't have any luck, I went with the recommended pin 44 and it works as it should. According to the…

I'd like to make a short video about it, maybe I am going crazy, they do say a picture says thousand words. Maybe all those laser fumes, but I swear up and down it's not working as it should. I do not know the specifics but constant analog voltage…

I forgot to mention, when I take TTL out of the equation, and use a vectored solution instead of raster output it works as advertised,using solely M03 M05 with G1 movements for Full power lasing. I'm trying to use a raster output.

Ok after playing around with the settings I decided to try a few different things. I'm using the latest Repetier firmware. A few things about my machine, I'm currently using D9 as the 12 V input for my laser, this controls the power on and acts as …

Ok I'll have to dig in to properly setting the laser PWM, Thank you

ok thank you for the input I will verify the path's are good !

Think I might have figured it out Have to enable Auto Level from the EPPROM Menu. Once I did noticed a very large shift at 20. Might be nice to include that in the firmware information...

what motherboard do you have ?

I would try to move the motors by hand, not retard strength. if they move and the machine is on (and the motors aren't commanded to off) you aren't getting the holding tourque (ie amps) from your steppers.
