Ok everything seems to be set up correctly on my boss 8 retrofit with
all in one dc and running cnc 11.
The x axis homes to its -limit switch as I set it to.
The z axis homes to its +limit switch as I set it to.
Now where the problem is the y axis was set to home on the -limit switch but when I shut
down the system and start it the machine wants to home which is the way it should be except
The y axis want to home to +limit instead of the -limit as I set it to .
What am I missing ? Any help is appreciated.
Thanks Jake

Re: Homing issue
Jake,
Create a file called cncm.hom in the c:\cncm directory. In it specify which direction you want each axis to home to. ex:
M92 /Z ;Move Z in + direction until home switch is tripped (specified in + Home field) and then back off until switch is cleared and index pulse is seen
M92 /Y ;Move Y in + direction until home switch is tripped (specified in + Home field) and then back off until switch is cleared and index pulse is seen
M91 /X ;Move X in - direction until home switch is tripped (specified in - Home field) and then back off until switch is cleared and index pulse is seen
M26 /X/Y/Z ;Home all axes at current position

Re: Homing issue
... and if you want to home the Y axis minus instead of plus, then use:
M91/Y
in your cncm.hom file.
If you run M91/Y, but the Y axis immediately moves plus (and eventually stops on the plus limit switch with a "Y+ limit tripped" error), then your Y- home switch is stuck open or has a loose wire connection.
