Title: THC and Z axis floating head once agine
Post by: marcinpl on November 30, 2008, 04:16:44 AM

Hi
I bough THC300 and all works perfect without one thing
When I have code G28.1 Z2 (I try with Z-5, Z10, Z3 and another)  Torch start going down touch material floating head press switch ZHome and nothing happend torch still go down.
I have NormalOpen switch when torch go down in diagnostic screen ZHome is off next switch is presset and Zhome led start lights but torch still go down.
For me it looks like G28.1 don't checks Zhome input signal
I read more topics about this problem on forum but I can't fix the problem.
Regards
Marcin

As I know, and correct understand you, Mach don't look at home switches when work, just when verify home position!
You may ON the soft limits.

Sound Logic solve my problem.

"Make sure the the  pin you use for Z home is not used for anything else.
In other words if Z home is on port 1 pin 13 make sure port 1 pin 13 in not used anywhere else in the config."

I have to check reversed on Z axis in home/limit setup.
THX again Jim
