can this be done (3 replies)

just a thought i put this in here due to the stepper on the extruder i want to be able to change the rolls what the wire does im no good with electronics but for instance say i wanted to do some light engraving i could take my print head of and swap it for a small rotary tool well a stripped down rotary tool in a modified head to make it interchangeable for instance like a laptop battery for example you have contacts on the battery and the laptop when they touch power can flow, so for instance on the interchangeable head and the extruder would have contacts on each and on the x carriage plate
so with the right software and hardware was combined to do this my be light milling and learning positions so, you could engrave your printed work dependant on height using bed jigs.
