Z Axis Home issue <resolved>

Post by viscoelastic »

This is a new install/upgrade.
I have enabled to home switches to: Home Switch
When I press cycle start I get:
407 Z+ limit (#50006) tripped
302 Movinq...
340 Z+ limit (#50006) cleared
302 Movinq...
457 Unable to find home
338 Job cancelled

It says it found the Z+ home switch then moves off of it and says it can't find it? That is confusing to me since it said it found it.

Thanks in advance

If your hitting cycle start, it by default looks at z, x, then y

That probably means that it failed to find the encoder index pulse within one turn of the motor after clearing the switch.

Are you certain that you have your encoder counts/rev value, on the Machine Configuration -> Motor Parameters screen, set correctly?

I should have mentioned above. It is seeing encoder counts and I confirmed they are correct + and -. I have the encoders at 8000 which seems accurate if I do one full turn of the motor.

FIXED! Thanks
@cncsnw I had my encoders set at 8000, they were supposed to be 20,000
