@donkjr Hi Don thanks for your reply and thank you for all your work on the K40… I have attached the pictures and config files as requested.
Connecting are as follows as per above first posted picture. (no change is original wiring)
(as per above, no changes)
G -> laser on switch (no change)
P -> laser on switch (no change)
L -> Fire Switch (no change)
G -> no change
IN -> 2.6 negative terminal (blue wire)
5v -> no change
24v -> 12-24 input positive terminal
GND -> 12-24 input negative terminal
5v -> not connected
L -> 2.4 negative terminal (brown wire)
with it setup like this the laser turns on and off as expected but the power level when set as low as s0.3 in the gcode runs at 20ma and wont even cut through 3mm mdf when with the M2 nano it would cut the mdf at about 11ma. (test gcode below)
G21 ; All units in mm
G28 ; home all
G00 X2.762953 Y240.677863 F6000
G01 X132.762873 Y240.677863 F400
Using the M2 nano board everything worked correctly.
I really appreciate your assistance and when I can afford to I will be purchasing a real smoothieboard and donating you some money.
I think I’m rambling a bit here. let me know if I need to clarify anything. Thanks again
