Need a little help on programming this lathe. I am trying to pick off a part from the main spindle and transfer to the sub-spindle. The problem I have is when I program a M17 (main chuck open) command, the machine simply stops and reads no further (cycle running light is still lit, and I get no error message).

The program looks like this:

M117 (Sub Chuck Open)
M203 S1500 (Simultaneous spindle start)
G0 H12.0 (Rapid Sub Forward)
G1 H12.75 F.025 (Feed Sub Forward)
M118 (Close Sub Chuck)
M17 (Open Main Chuck)
G28 H0 (Rapid Sub Back To Home)
M18 (Close Main Chuck)

Any suggestions?

Hi Jerryh,
Many moons ago i was on a bnc-34S (no live tooling).
We wanted to grasp with sub and pull out while chucks were revolving but machine
would not let us until we changed a parameter(no i cant remember what it was)
we rang our miyano agents to get it(the reason its not set as default is for safety)
try it with spindles at rest
hope this helps
