[Emc-users] DaDynamic compensation.

I think that EMC2 can become industry standard if it will oriented to the shop floor needs. I want to talk about of concept –idea new requirements to EMC2 as I can see. My point of view as a employee of big machine shop. 1. EMC2 must be able to do 5 axis dynamic compensation. I think it is sel

Kirk- If the DACs are $9 each you might want to look for alternatives. I've used some Sipex DACs before they were bought by Exar with good results. An Exar XRD5412 12-bit serial addressed DAC is only about $3-4 in small quantities. Almost the same pinout as what you are using, although 5V power

Kirk, A couple comments. You have the visible LED's in series with the LED's in the optoisolators. The threshold voltage of both LED's when on comes real close to the 5V from the driver chips. It probably works, but doesn't leave any margin. Would be better to route the visible LED's to ground th

Hi I am interesting in ZERO gage length capability of controller because length of tool is only on parameter of tool- length. Idea is create program on CAD/CAM and machinist will look for tool and whatever he finds –tool he measured put into controller and controller recalculate actual tool path. S
