A lot of people have negative things to say about Mach3’s performance and reliability (or lack thereof…) and not just on the Tormach, so it must be sensitive to installation and setup environment. I’ve been running Mach3 for 9 years now, and for a little over two years, I’ve been running my Tormach and Feeler lathe CNC conversion on HP t5720 thin clients with Mach 3.043.066. The t5720 boots off 512 MB flash drive (quickly) and has 256 MB RAM. I’m running at 35kHz kernel, and on the Tormach at 10000 steps/inch my rapids are 90 ipm which it does handily. I bought five surplus t5720’s for $20 each so I have spares. If I could run Pathpilot on the thin client I’d give it a try, but I’ve never had a glitch using Mach3. I haven’t done any probing however so I can’t speak to that…
But every time I shut down I need to re-establish machine zero so the Nomad wins hands down in that department!
