I'm glad you're getting good weather there in Germany. We're starting our few weeks of warm weather with green foliage. Soon the grass lands will turn brown, which is still pretty, but I prefer green. I am not a developer,but... I think Stepconf is more convenient when you have data for the driver card from the manufacturer available. Otherwise, you end up doing what the manufacturer would need to do, which is test, and cut and try all the parameters to come up with the operating ranges for each parameter. Of course the stepper driver manufacturer is in a much better position to come up with this data. If you don't have the data, then you may be better off editing the config files by hand. I believe, one feature of Stepconf is that it starts fresh each time and overwrites the previous config file. If you want to save the previous file, just rename or copy it with a different name. I think this has been an issue, and may be enhanced in the future. What driver card are you using? Do you have a description and/or pictures of your setup? ---------- Kirk http://www.wallacecompany.com/machine_shop/ ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
