There is no definitive documentation for the Sherline driver on the web, so we don't have the right values to use there. My understandign is that there are also several versions of the driver board, which may need different timings. If you search the EMC mail archives or on CNCZone, you should find a thread where someone posted (apparently) correct timings. Some work has been done to make it possible for stepconf to create Sherline-compatible configurations, but this is only available when you compile the TRUNK version for yourself. It's not a simple matter of changing a couple of numbers, the Sherline drivers apparently require incredibly long step pulses, which aren't possible with the type of configuration Stepconf generates right now.

The actual timing used will be limited by other factors though (to insure that there is enough time for other processing tasks). Hope this helps - Steve Hello Steve Thanks for your help It seems the values for 'Step Time' and 'Step Space' in the 'Sherline' option need to be transposed. So Sherline owners should select 'Other' and enter the following: 'Step Time' = 6000 and 'Step Space' = 1000.
