I know there are only a handful of smoothie modded lasers running, and they are mostly here. I guess my question then is, which method is preferred?
I’m perfectly ok with the one wire solution, that is Unless power regulation is also becoming the rave.
I mus say that i expressed myself wrong before. I meant a pwm capable pin. There is still much debate but lately many are going for this one wire solutions are there is no good reason to go any other way
PWM capable power IN pin?
I know that on my ramps I have D6 connected to IN on the LPSU for PWM intensity control.
Don’t let me confuse you. Where I said Mosfet I meant pwm pin
Why you rascal ! Now you’ve got me totally buggered up.
There is so much info, and so little time to study. I try to prevent myself from immersing 100% into it until I’m sure I’ve found the right path to follow. and now you go and mess me up!.. lol
Ok, I was under the impression that the L line was used to cycle the beam on and off and the IN on the LPSU was PWM’d to control the current (mA) of the beam. If I understand you correctly the smoothie now controls the burn by mixing duty cycle of the laser beam with rate of beam travel across the workpiece?
If so, the max mA is preset on the POT and if the controller wanted to burn through the piece it would just fire the beam longer and travel slower? as opposed to the stock way of having a set rate of travel and a set intensity combination where only vector work could be achieved,
Pot will stay in place and be used as a hardware max mA . Whatever you put on POT will be 100% . The L will be pwm by smoothie to control intensity in that range. Also note that one of the great features of smoothie is that it also controls power on acceleration and deceleration.
well, I thank you for all of your help… Im sure Ill have more questions later, but for now I’ll just watch the clock until I can get back to the lab…
