Re: [CAD_CAM_EDM_DRO] Current CNC options for Lathes with encoders ?

on 2017-09-21 04:40:36 UTC

They seem to recommend a resolution of 2000-10000 cycles per rev so yes, if you have a low resolution encoder you might be better off changing that to a "better" encoder. You could always ask them if your particular encoder resolution is workable or not.

You just said it was for lathes, I'm not used to general purpose lathes having more than 4 axis+spindle.

110V US kit?

Power supply voltage to Acorn is 24VDC. The kit ships with one with such a power supply, it doesn't specifically say but I'd guess it's universal input voltage like 85 to 240. It does come with a US power cord which you'd need to replace though :-)

Not trying to convince you, just a bit surprised about your arguments against it :-)

I had looked at that one previously, but not sure about using it with
the low res encoder on the lathes. That and the 110V US kit is not
helpful in the UK ;) Also adding 5th axis is a problem ... just shipped
a 5 channel USBCNC system so ideally need more than 4 channels.

Looks like there are a couple of non Mach3 options to use with the
Pokeys boards which I'm looking at currently.
