sonable but the black cat was
very light. I think I need to back down the velocity as it is moving over
the pure black area too fast to do anything.

for the number to use with the M67.

Thanks.

wrong? The laser is PWM between 0 and 5v.

- Is there an example of how to do this?

that way. Edit tool table or change tool number for
successive passes.
Spring pass as necessary.
Chip removal: compressed air or vacuum or both like the dental hygienist
does for cleaning. OK for one-offs but production needs a better idea.
That's my tuppence; machining is an adaptive a

invaded your shop. ;-)
Where is the can of murphycide?

Weird! Is it repeatable? Did the program use R or I,J? Just fishing? ;-)

Good luck.

I do industrial integration and have been doing it since 2003. I have

But
ll solution. In electronic terms
lathe spindles are pretty slow and have a lot of angular momentum. Most
lathe spindles
rpm range is not a lot over 5-6 binary bits.

I've actually considered putting a disc brake on the spindle. Not
exactly joking.
