Stepper 4 in the 5i25 can be used for the C axis, actually A/B/C depending on how you have it sitting on the table, that would be on the P3 connector on the rear of the 5i25, just load the correct config to make it wherever its sitting. That will of course push some of your I/O over to the P2 connector. This is something I would like to see as a ". filename.ini" in the main .ini file as it would greatly simplify the house keeping required to keep 3 configs synchronized for the first 3 axis's commonly used, adding the 4th one as appropriate for the job at hand. All 3 A-B-C . configs would still use the identical .hal file. Something that would be one of those "nice to have" options. In fact, it seems like the best place to put that loadup would be in the machine menu pulldown, under load A, load B, load C entries, all of which could be defined as [4th axisA] [4th axisB] [4th axisC] stanza's in the main .ini file. Much simpler than maintaining 4 or 5 otherwise identical configs IMNSHO. Don't mind me, I'm just thinking out loud about ways to simplicate the configuration of the machine according to the job at hand. To me, that would be at least as handy as bottled beer or pre-sliced bread. Could it be done, say for 2.7.1?
