I downloaded a Mach 3 Laser Post Processor from some forum somewhere, but it doesn't use PWM - it's either on or off - so it's not great - I've since changed to an Ortur Laser for all my laser stuff - for the PWM
@@bobheadzeek If I remember correctly (this was like 2 years ago) the main problem was the computer would have had to do the PWM and while that's OK for a spindle, it would not have been good enough for a laser - the breakout board I was using for the laser is something like C10 I think amzn.to/3OB9vEb
@@HoarderOfHobbies hi..cnc router z axis drop occasionally while program running ….and normal movement move perfect but cnc router engraving happen you have any idea about this problem
@@mdsharook894 If the z axis is falling while you are in the middle of a job - it could be something like Idle current reduction - if the Z Axis is not constantly moving, it's possible there's a switch or setting that allows the driver to lower the current to save on power and keep the motor cooler - BUT that could also mean it's slipping because the lower current isn't enough to hold the motor in place with weight on the Z Axis... I'd look into your drivers and turn off idle current reduction for the motor and see if it still does it
Which post processor do you use. How will the laser turn on and off during the job process without PWM?

I see, which mach3 breakout board are you using. Does it have pwm on it?@@HoarderOfHobbies

I see, you just got a whole new laser rig.@@HoarderOfHobbies
Which type pc mother board need to connect mach3 interface cable
I'm using a board that needs a parallel port from the PC
Look for some old DELL computers.
Can you share laser and mach3 wiring diagram
Sorry I don't have a printed wiring diagram - best I can offer is about 9 minutes into the video I explain the wiring
@@HoarderOfHobbies thank you🙂

@@HoarderOfHobbies In x y z a axis motor, both x and y is getting heat more but all the axis has same dip switch setting with same current and voltage
