Parallel would likely be simpler as it would mean fewer HAL changes. 5I20 will give better performance (as it can do hardware step generation) but you will have to change to the new firmware/driver = HostMot2 and new HAL file. I would not drive the steppers through the 7I37 for speed reasons but either directly from the 5I20 (assuming your step driver is isolated) Or if you want to be a little safer, through a 7I42T I/O protector or 7I47 differential driver card. > > Is there any ini and hal file to use as a example for my needs? > (servo+stepper) > > Please any help will be very welcome! > > Arnold > > ------------------------------------------------------------------------------ > Check out the new SourceForge.net Marketplace. > It is the best place to buy or sell services for > just about anything Open Source. > http://p.sf.net/sfu/Xq1LFB > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users > Peter Wallace Mesa Electronics (\__/) (='.'=) This is Bunny.
