An interesting read!.

The Roland should respond to something like "VS 1,1" added to the top of a
HPGL print file, (ie Velocity select #1, for pen #1). Is this not an
option?.



Thanks for reading. :)

It does respond to VS commands as low as 2 and that definitely helps in
slowing it down, but it's not quite slow enough.
I have to do multipasses on some materials to cut them.
Also I'm pushing the limits on the whole current vs torque issue.
As I slow down it down, it has a bit of a problem with torque or
overlapped stepper motor pulses (I haven't investigated yet) and so has
repeatability issues.
But I'm just a hobbyist here and it's a good start.
I may end up ditching the motors and electronics and starting off with
something better, but it was more along the whole "can it be done?"
thing than trying to end up with a piece of reliable production
machinery.
