Hi Dave,
I am only too pleased to share any info I have. All I know about CNC has come from you guys sharing your info.
Another piece of information - When the laser is operated at 2 Volts it produces a faint beam which is ideal for focusing because there is no loom and the beam can be adjusted to the smallest spot then it only lases when the voltage is increased to 5 Volts - pretty similar to the operation of the laser cross hair pointers we use for the tool positioning.
Couple more pics. - The Mach write wizard allows GCode to be created without Z moves which is ideal for experiments - This little laser cuts through 4mm high density foam (the stuff I use to protect RC servos and receivers) too easily, in fact it scored the surface during the fast G00 moves. It also makes short work of pvc electrical tape too.
