What I did was keep the power supply and spindle motor the same, mine was working ok and hasn't caused any
issues as of yet, I am not using the PWM spindle control or relay output to turn the spindle on/off. I used the cabinet too, I cut out the back side of the
cabinet and left an edge that is about 3/8" all around keeping the threaded holes
for mounting the cover. I then cut out a piece of 1/8" thick aluminum that mounts on the inside using #4-40 hardware, flat head screws up top
and pan head screws at the bottom. I also cut out reliefs for the cabinet screws that poke through when attaching the cabinet cover.
I mounted the G540 and spindle jack plus a 8 pin jack for limits and probe on the aluminum plate with the G540 above and other jacks at the
bottom. Along with the jacks is a fuse holder and a power cord grommet (power cord entry module would not fit). I re-used the X Y and Z 4 pin motor jacks
by removing the molex connectors and wiring jacks to the DB9's that came with the G540, this makes a short adapter (4 pin mic to DB9) that works fine and you
don't have to replace the motor plugs.
