Kitamura MyCenter Zero LinuxCNC Retrofit.

I attempted to repair my machine but I have found the simplest way was to just start fresh. This machine was state of the art in 1989. 28 years later we have better options.

In 1989 the electronics cabinet and the operator control panel where stuffed full. In 2017 I have ample room to work and allow for airflow.

I am using Delta servos on all 3 axes. The Z-axis includes a brake to hold the head up when not under power or during Estop. The spindle will be driven by a Delta VFD. These will be run via a Mesa 7I93 Ethernet and Mesa 7I77 cards. I also have a Mesa 7I76 (stepper) card that I may use to interface the Spindle VFD and use the extra I/O for the tool changer. All of these will be controlled by LinuxCNC on an industrial panel mount touch screen via ethernet.

Follow me on Instagram for in process updates. I ocasionally post videos to Youtube also.

Kitamura Mycenter Zero Mycenter-0 Manual

Kitamura Mycenter Zero Manual

For anyone who needs a manual for a MyCenter-0 see the above link. 

I purchased a 1989 Mycenter Zero in January 2017.

Now I am attempting to convert it to LinuxCNC control. I had to replace the z axis servo and amp. I did so with a Delta servo 750w with brake. I have also replaced all of the airlines as they were old and brittle. I pulled the Kitamura System 1000 with Fanuc O-M controller and have replaced it with a touch screen PC booting Linux.

I am currently working on getting the spindle and axis servos connected to the Mesa 7I77 so that I can get to the configuration portion of this conversion.

11×26 Lathe CNC Conversion

I have the 3 phase Leeson motor hooked up to the Teco L510 VFD. It is running strong. I suggest this modig=fication even if you do not intend to convert to CNC. You can hook up a potentiometer to control the speed from the panel or just adjust it at the VFD. I have the stand offs turned. Now I just need to machine the mounts for the steppers and ball screws.

Metal Furnace

I cast the refractory and cured my new furnace. So far I have < $150 in my entire casting setup. The biggest cost was the Bentonite Clay, mold starter kit, and Crucibles I purchased. I hope to be melting metal next week.

Hello and welcome!

My goals for this site is to have a place to share ideas and demonstrate how I accomplish so many of the tasks that I am faced with regularly. I had to learn many skills the hard way, then came the internet with free sharing of information. This is how I give back.

I plan to cover topics such as,

  • Machine shop operation
  • CNC and other automation
  • Machine design and optimization
  • Research and development
  • Foundry operation
  • Shop setup
  • Lean manufacturing
  • Promoting yourself in the digital age

Please feel free to comment. Especially if you know of an easier way to do something!
