    Is it possible to control the laser on my machine and if it is possible how do I go about setting it up?

    I'm using the HPGL protocol to communicate with the plotter

    It appears that the KnK Zing machine uses a custom protocol based on HPGL.

    The commands for operating the laser are:

    Laser on: SLN;

    Laser off SLF;

    Still trying to find out more about the protocol commands but realise that it might be good to have some user programmable buttons in the control interface to map to things like laser on/off. I'll add a feature request to github.

    To accompany the programmable buttons, if using a laser it would be good to have a way to offset the laser <> cutting head position. Normally in 3D printers / CNC's this is a simple x,y tool offset. Essentially the laser is the equivalent of a tool probe, such that once the job is 'probed', the origin is then set to current position + tool offset which effectively places the cutting head above the probed position.

    I'll raise another feature request :)
