Machine: ebay K40 with M2Nano originally
Board: cohesion3d mini v2.2
Firmware: Smoothie “Its a new board as have had it waiting to install for years! and I’m using whatever it came with”
I have installed the board and am having issues with the laser firing, the movement works great and have tweeked the settings to get this smooth.
Using lightburn when i run a job it puts the laser to full power every time even with power set at lower levels such as 4% etc. It is on even when moving between cuts…
I suspected the PWM period so have tried 200 and 400 but this makes no difference, so i then moved onto testing with the PWM tuning guide here: https://cohesion3d.com/knowledgebase/pwm-tuning-for-smoothie-firmware/
running the following moves the gantry but no laser fire…
- G0 X0 Z0
- G0 X0 Y10
- G1 X300 S0.8 F600
So i am confused as to what i have done wrong here, could someone lend a hand and help me out!?
I have attached pics of my setup.
Thanks in advance all!!!
