I’m hobbyist and I need your support to convert a Brideport into a CNC milling at the lower cost possible. The backlash on my BP is 0.005.
I’m planning to buy AC servo motors with drive from aliexpress. I think I’ll go with 750 w for X and Y and 400 w for Z (see the spec below / about 1000 US$ with drives and cables and shipping include). I’m not sure what I need between the servo drives and the pc (I’ll use an old laptop) and I’ve never had a cnc machine. This CNC world is new to me and I can’t wait to explore it. Thanks for your advices.
