RE: [CAD_CAM_EDM_DRO] Re: EMC stg2mod.o and problem with homing

Asim,

I think you should try Jon's suggestions first with
HOMING_POLARITY. If that does not work we can check
on index latching.

Please understand that there are two Servotogo cards
in use with EMC:

Servotogo model 1

Servotogo model 2

Which is yours?

The index problem was with the model 2 board only. I don't
think the fix was in BDI 2.16.

I saw this exact problem with a 2.18 BDI with my Universal Stepper
Controller,
which looks exactly like the STG cards to EMC at the motion level.
What we did was reverse the direction of the homing motion
(HOMING_POLARITY) in the ini file, and approached home from the other
direction. This worked fine.
