Dear readers ,

Recently I purchased a Colchester Tornado A50 lathe .
I have some basic experience in programming but I'm suffering some startup problems that I cant manage to solve .

The turret is installed with 4 cutting tools , 1 workpiece stop and 1 drill . I made a workshift Z0 value on the workpiece stop and made an offset for all the tools by cutting and measuring . However when writing a small program with a tool exchange to the drill the turret goes everytime out of range in the Z axis . In other words I can't switch to the drill in a safe position .

I only manage to switch to the drill by T1200 command (drill is in postion 12) without the turret moving in Z X axis . But then I have no offset / reference so then I enter T1212 and the turret moves out of range again or moves to - Z position to close to the workpiece .

I tried with the T0000 command but that doesn't solve the problem .
All the other tools seems to work fine whit the T0000 command or T01XX offset command .

Probably there is some mistake in my tool allignments/offsets but I can't figure it out from the manual how to do it right .

Any comment/help is very appreciated .

Best regards,
Kenny
