I remixed the files that another guy released as open source today. Sending to laser tomorrow.
It uses plumbing pipe and ordinary bearings for the guides instead of imported china linear guides, and threaded rod.
It however can be converted to use more robust guides quite easily.
I'll have a US source set up within the next few days to order the mechanical bits.
The electronics, if anyone wants, I can set up a control box and software for order.
This is a perfect entry level machine to do signs, and with upgrades, you could use it to make money taking more elaborate jobs.
