Training and Documentation

---

The Procix PC has both V-Carve installed as well as Mach3 to control the CNC.

Mach3 has an optimized, custom screen set installed, although if you wish, you can change it back to teh traditional screen. Just remember to return it to the custom set when you are finished.

Hold down method: The hold-down table has a grid of threaded T-Nuts that can/should be used to hold down your material. If you wish to make your own sacrificial / holding system, simply prepare to fasten it down to this grid pattern. Use the 1/3-20 screws (or bolts if you are gentle).

The spacing of the threaded nuts is 4.861" (123.63mm) on both the X and also Y axis. Wtf is that spacing? Why not a nice round English or Metric spacing? Well, that is the spacing of the T-channels in the underlying bed. Get used to it and make your templates.

The T-Nuts can be damaged by either over-tightening them, or by pulling them off vertical. Please be smart and not too aggressive.

Machine history

The Precix CNC was originally pitched by Scott Y. on Feb 7th, 2020. It's purchase for the spaced was voted on during the Feb 20th, 2020 meeting.

The machine arrived at Protospace on Mar 26th, 2020.

Over the summer the machine was idle due to the 2020 COVID-19 Pandemic.

During this time Members Connor G. , Danny P. and Zachary J. started to work though the machine and evaluate it's condition and begin it's acceptance work. This work is documented on the admin google group post "CNC router planning/build thread", authored by Zachary J.

Going though the machine it was found that the X and Y motors were both burned out and had to be replaced. The encoders on all axis were replaced and the motor drivers were also all replaced. The controller computer, and interface cards were also replaced at this time due to poor/wanting/or no documentation on parts or interfaces.

Motion system breakdown (there is a error in this image, it should be G320X not G520X)

On May 8th 2021 the CNC made it's first official project, a 4' x 5' art piece that is hanging somewhere in Protospace (can you find it?).

The controller was changed in Aug due to the Galil DMC-1803 card not wanting to register in the system. We have moved to a Smoothstep board with a C25XP integrated card mounted to it.

Motion config (As of Aug 29/21) is as follows

The first training session has yet to be held at the date of writing (06.01.2021)
