thanks for the info guys, everyday is a school day!

   So are we sitting in the front with the nerds and thick glasses or in the back with the cool people? I am starting to think the nerds were having fun all along! I wear contacts now so I can look cool. I had great eyes in school. Guess where I sat then?
I want to die in my sleep like my grandfather, not like the passengers in the car! :-)

I did some more reading today, as i just found out cs labs have released an english manual for the ip/a. Previously I had not enabled index homing. I assume with this enabled i will get much moe accurate homing???

this works fine on my Y&Z axis, but when i try to enable this fo the x axis, i get an error when homing that machine
"index distance not allowed in range..."

waht is odd though is that the x and y encoders are the same with 1250 pulses per revolution, so why should one work but not the other??

Could be your index is very close to your switch closing and thus it is not being seen until the next revolution. If you can just remove  the belt and turn the motor 180 degrees and then engage the belt again and see if that helps.

Thaks hood,
I've solved this issue now, I moved my home switch slightly along it's axis, i guess it was not in nd ideal place for the encoder.

So hopefully now I should have mouch more accurate homing??

Would I be correct in assuming that havig a higher speed for homing the mahcine will not make it any less accurate at homing?

Ok moving the switch did the same job as rotating the motor :)

Yes your homing will be much more accurate than using the switch alone, it should be extremely accurate now :)

The speed of homing should not really make too much of a difference in accuracy with the Index Homing.
