***Liam said it took a straight DC motor. So proably PWM speed control if that's the case.
 
−
* a way to fix the drill to the x/y platform.
 
−
** Spindle is an interchangable module. Any arrangement with the same OD of housing will fit. Will however need round-profile drive belt and motor pulley. Emco unimat spares may be suitable.
 
−
* chuck for the drill.
 
−
**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. There may be something more suitable for auto toolchange (one day)
 
−
* small drill bits.
 
−
** As standard does not take drills but "gravers" that go through the whole spindle for precise depth adjustment
 
−
** It would be nice for it to actually be able to still engrave/mill rather than just drill holes when repaired.

* some rewireing to fix endstops etc.

At the moment the engraver comes with an embedded computer (386FX!), which powers up and works fine, and is connected to a control board that has 3 x [http://imshome.com/products/im481h.html stepper drivers] and a [http://www.onsemi.com/pub_link/Collateral/MC33035-D.PDF brushless dc motor controller] on it.

−
== Choices ==
 
−
 
 
−
We've got 3 main choices:
 
−
 
 
−
# Use the existing controller, but we'd need to give it the steppers and drill that it expects.
 
−
# Chuck the existing control board and use an arduino or something to talk to the [http://imshome.com/products/im481h.html existing drivers]
 
−
# Chuck all the electronics and do it all our selves.
 
−
 
 
−
The first may be the quickest, but we'd need to get identical parts - the manufacturer may sell them, which might make them more expensive.
 
−
 
 
−
The second will involve some hardware reverse enginerring to work out the pinouts to talk the existing drivers
 
−
 
 
−
The 3rd might also be fairly easy - presumably we can use the reprap style electronics with it??
 
−
*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. Not much use for immediate goals though.
 
−
# 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.

This is a project to convert a CNC engraver to also allow it to operate as a CNC pcb drill. The Engraver is a Dahlgren Wizzard 2000 ST.

Currently, the engraver is actively worked on by Martin_p, and for the time being lives on the floor in the arts/crafts corner. The original roadmap/discussion has been moved to discussion for this page.
