Engraver advice needed

[John S]

Looks like a candidate for a rip, gut and start again.

If you can identify the step and direction signals inside the controller you may be able to patch in the control wiring from a break out board and use a PC and control software of your choice.
Does the engraving head have full variable height or just up/down with pressure adjustment?
The spindle looks just like a mystery item which came with my Gravograph IM-3 pantograph.
