Home Sweet Home - Installed the HOME switches and tested them.

I am really excited about today's post. I've had the milling machine since about 2001 or so... and this is the first time I have completely retrofit it with a full set of automatic homing switches. I got some magnetic sensors which are impervious to dust, moisture, noise, and all the other "stuff" that usually would interfere with being highly accurate.

I can now tell the machine to find "HOME" and it will automatically move to the proper locations... not only that... but it has an amazing accuracy of about 1/75,000 inch or so.

That's 0.00075 inch or about 0,01905 mm give or take... a piece of paper is 0.003 inch. (0,0762mm)

I was hoping to get it within 1/1000 of an inch... so I'm very happy with this!!!
