Jim,

I am not sure what code you are comparing, but I would guess the time savings would be in the time for the operator to restart the program. Am I right?

In our code to cut the dowels used to make our cue shafts. We actually make 2 passes on these, so there is no rapid back to the start. With our taper passes on the cue shafts, we also make multiple passes with each session on the machine, but we also end at the other end on some of them, requiring the rapid moves.

I am curious as to what the time savings comes from?

The biggest time killer that we have is the load and unload time. When we are taking parts off and replacing them, is the biggest down time we have. My next big machine project will eliminate this down time. The machine will always be cutting parts!

Royce,

sounds like you need to add a pallet changer system , with a simple airlock lots of after market companines
that would prob work for you

almarktool,

Believe me, my machines are way to simple to be compared to the big machines that operate with pallets and pallet changers.

But it is an interesting idea! I just couldn't afford it. Making a profit in the pool industry is not an easy thing to do!

Royce, I figured that you made two passes most of the time. I was curious if part of when you do rapid back to home, is the next shaft loaded already? If so do you have to wait for the operator to hit the cycle start button? It shouldn't be too hard to add a trigger to automaticaly cycle start after a part loaded button is pushed. By the way, I was tring to prove out wheter simulanious movement as actually running faster than commanded feedrate. When both motors are running at the same time, then both move at different feed rates unless they move the same distance in which case they actually run faster than commanded feedrate. I think though that Mach3 still locks down the feedrate to commanded. I hope this makes sence. Anyway, if your system is maxed out and you move faster than max feed rate such as G00 the stepper could loose pulses.

By the way, I believe that you met Mark, almarktool, at the US. Open. He is a handing guy to know. If I needed a special machine part made, he is the one I would ask.
