I have what appears to be a very similar machine, mine is a Model 810 built in 1980. I have set it up with Gecko 320's and the original PS rewired to produce 56 Volts.Currently it is running on EMC2 2.1.6 with a fourth axis, coolant control, and spindle control. The EMC gang at the CNC Workshop in Galesburg were instrumental in setting up the last two items along with a second Par Port. Thanks again to Chris, Steve, Jeff,and John for the big help. > I have searched the net and came up empty. > I have a Wells Index knee mill running Emc2 and the 80's vintage mill > uses magnetic starters forward and reverse. > I would like to explore spindle control for rigid tapping and I also > would like to retro a lathe with Emc2. You will need an encoder and connections for rigid tapping, check out the Mazak setup. I use an extension/compression adapter for non-rigid tapping which works just fine for my use. I also have a Hardinge CHNC with no control as a retro candidate. > 2.

My machine is running with an Athlon 700 processor through 2 Par Ports, at 56 Volts I can get 72 IPM at a high acceleration with the Gecko's.
