Apparently it wouldn't be a bad idea to have Mach/EMC control over accell rates, as some of the built in controlers don't seem to. This gives problems/vibrations at corners/curves etc .

The more I read, the mor I thin EMC (which I use for my CNC) is the way to go . You just need to have a plan to turn the laser on/off ... Z axis pin outs are one solution , as long as you don't want auto bed height adjust/beam focus

I'm intrigued at the thought I don't need a dedicated PC to run the laser though... just a mem stick with the image files on ...this could reduce the over all cost by a couple of hundred (no pc needed) and the amount of desk top space each machine needs.

Obviously I am thinking for business use.. as for DIY/hobby it might not be an issue.

I'm planning on getting several machines running in the 'shop
