Hello
This is tricky but doable.
The main issue is that when the machine slows down to turn a corner, the laser has to be metered, as full output has to be lowered based on the speed.
The other issues are getting the beam over to the head safely and reliably, as well as the final issue, that the table isn't built to have a laser work on it - a proper laser table holds material up and has some vertical space underneath for fume extraction and to prevent burning of the table.
Depending on how good of a product you need, and how much time and effort you want to put into it, you can overcome these issues, but it might be best to leave your Techno as a CNC machine, and find a used laser system - might be cheaper than the time and cost to retrofit at the end of the day.
Regards,
Eric
