Laser and CNC

I am new to 3D printing and we purchased a ZMorph VX 3-in-1 printer, laser, CNC device. It comes with a really lousy slicer and it almost unusable, so I am going to try Simplify 3D. My question is, has anyone tried using Simplify 3D for any laser cutter, laser etcher or simple CNC? I saw a post from 2016 of someone asking, but there weren't any replies.

Simplify3D isn't designed for CNC or laser. It's strictly for slicing solids. A lot of times, the tool you use for design will have the capability of generating the tool paths you need for CNC or laser. I know Fusion 360 does.

OK, thank you. I am new to Solidworks, so I will look into using it to get the Gcode for laser and CNC. Appreciate the info.

Yes, you can use Simplify for Laser and CNC movement, if you have a setup to do it and know how/what you’re doing.
But, Simplify won’t generate the Gcode to do it. It only does what the Gcode tells it to do.
Thus, you need to generate the Gcode either by Hand coding or by using other software (preferred).

I have done it with both Simplify and Repeater to confirm this but I have a CNC machine so, it was only a demo (though I designed fixtures to attach to the Extruder to hold a Dremel tool for show&tell...).

• The Gcode for 3d printing is not the same as the Gcode for laser/CNC.
• You’ll need to Generate the Gcode either by Hand coding it (easy example below). Or, generate the Gcode using a program that does it (such as FreeCad).
• If your 3d-printer /other-machine has a Laser or Milling head attached to the Extruder, then Yes, you can use Simplify to control it too.

Example below is simple hand-coded Gcode demo using Simplify to ‘Preview’ Gcode [File>Preview Gcode]

The Hand-Coded Gcode:
G1 Z25.0 F500
G1 X25.0 Y100 F1000
G4 P4000
G1 X100 Y110
G1 X25 Y110
G4 P2000
G1 X100 Y110
G1 X25 Y110
G1 X100 Y100

Previewing in Simplify Click image to see video, I hope

Added the following video of Simplify running Gcode for Milling a test block of wood.

Gcode generated in FreeCad and I did not fuss about where to place the block so, it’s not on the bed...


Useful Tip:

Gcode files often have different filename extensions. But, all are simply ‘Text’ files.

For Simplify to recognize the file, it must have a .gcode extension.

Thus, after ending up with a satisfactory gcode (however you generated it), simply change the filename extension and Simplify will load it...
