A couple of days ago my grizzly 2hp spindle motor let out it's magic smoke. So now I'm waiting on delivery of a new 3 phase motor + variable frequency drive to power it. This will allow me to have better control of the spindle speed and I planned to upgrade eventually, however, I had hoped to avoid the cost until much later in the project.

While I'm waiting for the new motor + VFD, I plan to install the ballscrew for the table X-axis, which will replace the ACME screw, enabling smoother table movement with less friction and much less backlash than the crappy OEM lead screws.

I should have a decent amount of time to work on this project over the holiday as I have a week of vacation from work. I'll try to post another update next week.
