My cnc engine lathe (18x40) actually came with a rod that mounted in the outboard end of the spindle to serve as a depth stop. It was quite long and had...

Worth mentioning that you can buy just the pathpilot software from Tormach on a usb thumb drive. Many of the linuxcnc guys have done this and use pathpilot...

I can't find the model number outside of Jet 1340P but the serial number is 41086. I do have the wiring schematic but I'm still puzzled.

I had a speedglas for many years and recently got a Harbor Freight ArcSafe helmet which is far superior to the one I had. Mine was a older model Speedglas...

Skunkworks explained the math limitations of speed well. On your machine the speed is limited by the power of the stepper motors and their torque, no...

Solution worked out well. Personally I would have let my cnc "go through the motions" Such parts are easy and can hit any dimension...
