Lecacy Homebrew CNC upgrade test

First test of my CNC upgrade to the Legacy ornamental mill. I'm using 387oz. NEMA 23 steppers which don't provide enough power in some situations in the test run: 1. the Z-axis stalls when moving up. 2. The A-axis will stall if too deep a cut is made.

In the video, I'm taking about a .125" depth pass. I know just enough about mach3 to make this happen, and I'm using my z digital indicator for reference.

My goal is to turn 1.5" diameter dowels, then thread them to 1"-5. So far, I'm taking two passes on my 1.625" blanks to get down to size, then I run up my A axis motor speed settings and run some sandpaper over the dowel while doing an A100 command. I wouldn't say that I'm doing anything awesome, but it works.

So far, so good, but I sometimes have problems with raising the Z, which is not so bad when turning the dowels round. I'm more concerned with the threading; if an error happens there, my dowel will be ruined.

If anyone wants to share some advice or ask questions, i'll do the best I can to answer them.
