What year machine? running what control?
I run mine off a laptop with Mach3 and a controller I built. Total cost to retrofit machine is at about 1500-1800 right now not including the laptop.
I do not yet have the toolchanger working but I am getting closer.
I LOVE my CHNC circa 1980. It is the 5C collet superprecision model. it takes fantastic cuts. has a dead nuts spindle and is solid as a rock.
These machines are great, but the older ones have obsolete controls (mine was originally tape)
Got mine for 500.00 with no control. excellent shape, but needed a retrofit. I would buy another if I could fine one at that price again!!!
