I connected the boost inputs to the parallel port so that I could controll them via Mach 3. Haven't had chance to try them yet as I have been diverted on a bathroom project!

Just to say thanks again for all the help. After a short half term break, I now have my Starmill PC fully converted to Mach 3. I was able to reuse the existing spindle-motor interface board after making a few modifications (I attach the circuit diagram and a photo of the modified board). I had to re...

Thanks again angel-tech. Came out easily with a gentle tap. The 'drawbar' is just a 1 1/2" long 7/16 UNF bolt.

Excellent idea. Just had a quick look on e_Bay and seen a number of R8 Bridgeport Sidelock holders with 7/16" UNF drawbolt. At the moment I'm struggling to remove the existing Easychange holder, is there any advise you can give me about how to go about this? Is there a recommended drawbar torque set...

Many thanks angel-tech.

RE: My 1994 Starmill PC Mach3 upgrade. I attach a few wiring diagrams that I made over the weekend, as you can see, there are some differences to the Baldor Rack circuits. On close inspection, it looks like I should be able to re-use the existing spindle-motor driver interface board (Optimised Contr...

Many thanks for the pointers to the wiring and tooling links; it looks really helpful. I will take a closer look at it all over the weekend.

Hello, I have recently purchased a Starmill PC with a despatch date of February 1994. Unfortunately, the machine came without a manual, software, or any tooling. I do have a little experience of using Mach3 on a CNC lathe, so I would like to convert the mill over to this. I have read recent postings...
