Hey Everybody, i'd like to convert a mill to emc2 and still have an unused stg1 card.
Last Friday i had the machine so far that i could get all axis moving and homing, but i got no signal from the linear encoder's index pulse. I did connect the (undocumented) hal stg.X.index-enable pin to the axis.X.index-enable pin for all axes. And then I can see the different Xindex, Yindex, etc signals being driven high for the respective axis when homing starts. But the stg driver never puts them back to low again to indicate that the index pulse has been found. I also put HOME_USE_INDEX = YES, HOME_LATCH_VEL = -5.0 in the ini. The index pin of the Heidenhain linear encoder is active high, just like hal_stg.c expects it to be. Now i'd just like to see if anybody is homing on the index pin with a stg model 1 card before i dig in deeper to find out the reason. The encoder is 200 ticks/mm. Before this machine was working with an older 198X cnc controller, which is getting capricious out of old age. However the old controller did detect the index pin, so i'm guessing/assuming that the hardware of the encoder is fine, especially since i have the same problem with the stg1 card not finding the index pin on all axes.
