Hardinge Lathe CNC Retrofit/Conversion

[Neale]

Chaz - I expect you've fixed the "servo error" issue by now, but I've also been setting up a 3-axis mill system for a mate (project on hold pending him getting some mechanical bits sorted) and had all the SZGH kit configured on his coffee table for testing. I found exactly the same problem until all three servos were connected. I was a bit worried when I tried with just one and kept getting errors... Seems like a nice bit of kit, though.

Looking forward to seeing this lathe project progress - good luck!

I haven't had this issue but I'm using Absolute encoders and I think you and Chaz are using Incremental which might make a difference as the position is saved in memory and talks to the controller first so doesn't rely on the motors encoder to report back, however, every so often I do get one drive fault on start-up. Can be any of the drives, it's random, reset and it's fine never does it again no matter how many times you switch on/off.!! . . .It's a strange one.?
This is just on the bench still has I haven't had time to fit on the machine and It's probably because it's rough arse wired on the bench and running through a multiplug extension cable on a 13A plug with no Inrush or line filters but I'll be contacting SZGH before fitting to check but thought I'd mention it just in case anyone else is having similar issues.
