Leadshine EasyServo Question

[JAZZCNC]

You can get to the encoder DRO's in Mach3, do a search in this document for them; http://www.machsupport.com/forum/ind...0;attach=27839
Then you might be able to write a Mach3 'Brain' to achieve what you want.

But only if the encoder talks to Mach3 and in this case they don't. The loop is closed at the drive and Mach never see's the encoder so that won't work.

Not sure if the drives will report encoder position thru the serial connection but suspect they will or could be made too.? In which case it may be possible to feed this to Mach3 then use a brain like Eddy suggests.?

Jazz if its possible to get the driver encoder position back into Mach3 or even use the build in soft DRO's in mach3 like eddy suggested along with the sensor output it would create some very useful possibilities to toy with like e.g. a contactless edgefinder for setting work-offsets. I might be totally wrong but my gut feel is that the mach3 soft DRO's does not always know where the machine actually is in real-time while moving if you use a controller that does buffering etc ?

If it does all come together this is a good video on Brains; https://www.youtube.com/watch?v=O8V7dZy02og

Thanks Eddy, that helps.

I've just read the servo manual and it looks like the only way to get at the encoder is via that RS232 interface.

Don't know if this is any use for your limits application, Hiwin - Intelligent Linear Guideway ( Page 4 ); http://www.hiwin.com/pdf/lg/linear_guideways_e2.pdf

Thanks Eddie, looks interesting! I wonder if its very expensive?
