PCB mill

Hi yes it makes sense,
You could use you start gcode just for CNC files to do this.
-
Why do you need to reverse the axis direction? But yes that would work but would have the effect of reversing the direction for homing and all actions.
So to make sure everything is safe, I insert:
-
M569 P* S0 at the beginning after the homing procedure
-
M569 P* S1 at the end before the homing (if you have one).
Thank you

I'd depends how you want to use it. As it's a printer as well I should have homing and everything working with the axis I the correct direction and then just have the gcode "print" have the axis reversed.
Hopefully someone with more experience with generating gcode for pcb milling can say how they did it so you don't need to use this "hack"
-
Hmm… could we have the Z-axis inverted solely for a specific tool?
I assume that laser engraving would have similar requirements
-
Can we declare a tool with no heater and extruder, just a fan
-
I am getting ahead of myself, as my printer is almost done, but very interested in this.
My question is, can I use 2 SD cards, one for the printer and one for the Milling?
The latter is more like a cnc machine than printer and setting up a entirely different profile makes more sense to me. Laser engraving and PCB milling could be done with the same setup, just different gcode processing. -
Yes, you could, has long that you have the same version of the software installed on both chips.
Also, you might have to reinitialize them on occasion.

ok I did a few test runs, works great. Only problem is the PCB that I am trying to print is too tight… even a .2mm cutter is too wide (obliterate the trace).
So I am changing to laser cutting for the PCB...
Anyone knows if I can change something in my config.g files to run a 24V printer but to have an output of 12v at a specific pin?ATM, the laser is on constantly and I set up so when it moves the Z axis has to move 20mm which increase greatly the cutting time.
-
Switching 12V power to the laser control module constantly is a bad idea. Most laser control modules have a TTL level input for turning the laser on and off, and you should use that.
-
The laser doesn't have a TTL, it's an old highschool project, a black paper burner / match lighter I made with a laser diode from an old CD burner, I had built a Step down 12V to 5V.
I think that the simplest thing should be to build a new Step down for 24V to 5V and replace the older one.
Thank you for you assistance.
