**Collets are much better than a chuck. An ER12 collet chuck would be better than the cheap dremel style, but needs a decent sized motor shaft.

*Solexious' stepper drivers could be used, though not with reprap controls. Might also be a good target for grbl. | *Solexious' stepper drivers could be used, though not with reprap controls. Might also be a good target for grbl. | ||
== Proposed roadmap == | |||
It currently seems easiest, and possibly more reliable long-term, to fix rather than hack. I suggest we go with this until proven otherwise. | |||
# Check pinout of control board output. Will provide nessesary info on stepper voltages, wiring and spindle motor control, as well as verify controller function. | |||
# Presuming control output okay, obtain and fit steppers, wire in stops, test motion. | |||
#* If controls damaged, then move to other controls | |||
#* Check if brass wheel causes any motion difficulty | |||
# Fit new spindle motor (see manual page 26 for stock assembly diagram) | |||
# Make spindle bearing and collet holder (see page 25 of manual - this may be very very tricky. Many precision parts) | |||
#* Alternately make missing parts for existing spindle mount | |||
# Fit replacement table | |||
#* Pricing is hard to find, but many engraving machine suppliers sell replacement T-slot tables which will provide an optimum mounting solution. | |||
#* A temporary table made of MDF or similar should be enough to test function crudely. | |||
