Hi terry i too am now using the HM2 setup and find i only need very small values on the tunning to get a some what stable system 0.2xx or so ( i have not finished tuning yet) find it odd how other people use very large values dont know if this is a HM2 or what. maybe some one who knows can point it out. i didt know if in my case as my servo amps have a preset loose gain this is why i was seeing lower values needed than normal.
as for the mark/index homing i have not enabled this yet i planned on playing with this tomorow if i get time been bussy setting up everything else on the mill getting it to function etc. but i dont belive there is anythink else needed.
