we now have 4 machines on Linuxcnc (3x Laths all hardinge , 1x VMC
leadwell) soon to be 5 (will be a 2nd VMC) all around 1985up machines ,
these machines had good solid Iron (something some of the newer ones
lack), with only a few needed serv

LinuxCNC isn't the problem. The old iron is. And it has nothing to do w/

Are you talking about retrofitting LinuxCNC to a used CNC machine here?
Many old CNC
Used cnc machines are so common and fairly inexpensive, retrofitting
with EMC doesn't make that much sense once you factor in the amount of
time it take to do a retofit. However, if a replacement machine cost
hundreds of thousands, or if you are doing 10 or 20 machines, then
retrofitting can proba

I think it depends on what you mean by "retrofitting".
Converting a manual machine probably does't make much sense in many
cases.
Well dk, this is part of my tasks starting on monday...
I do indeed already have some experience as mentioned on this list and
elsewhere and I have in fact not decided yet what to think.
