I am looking for someone that is very familiar with Biesse XNC programming. My scenario is this, I have a 1997 Biesse 336 rover with 2 work zones. I am running 1 program, (only using 1 router spindle) 200 times using both zones. I am wondering if it is possible to keep the spindle powered up (not turn off) after each program is finished rather than turning on and off constantly. With all the capabilities, and advanced programming that Biesse has built into these machines, it seems senseless that the router spindle has to turn on and off constantly. I might understand if it would possibly be a safety issue but if I step into a zone while the head is working in that zone the machine stops. Any insight would be appreciated.

If it's G code can't you just edit out all the M03's and M05's?

I have posted a simple routing program. What would you suggest to remove ? I don’t think it would be as simple as what you suggested. The fixed cycle (POFF) is what turns off the spindle and determines the end of the program.

That's not normal G code as I understand it.

Sorry.

I ran a rover 321 for 8 years. Ran it the way you have it programmed for years. Thousands of panels.

The POFF fixed cycle controls turning the router off. On your style machine, it was constructed with safety in mind, so there is no "clean" way around this. The machine views the POFF as the completion of that program and awaits the operator to select which origin he wants to execute that program in next OR which program he wants to execute next and which origin to execute that program in. If your router is set up correctly, you are talking about 8 seconds per cycle. Whatever you do never reduce the acceleration or deceleration of the router to less than 4 seconds.

Just change the L=POFF to L=PSU. It's a different end where i believe it does not turn off the spindle. I've done this before. Also you can if you know what your doing change the POFF sub routine. Those old machines were great cus you could change almost everything.

By changing the POFF to PSU that will only pause the spindle. It will not end the program and release the part to move on to the next program. Biesse says that what I am asking cannot be done but with the extreme flexibility of this machine program, I find that hard to believe. Perhaps the POFF fixed cycle could be modified, but in what manner. That’s why I am reaching out to all the people who have worked with these machines over the years.

I love this kind of stuff. You are correct. Your 10k router will last another 3 years if it doesn't have to turn on/off 10k times a year.If you wright one program. Left side first then L=PSU, then right side like its one panel. Then a conditional jump command like
N100 JM:1(B<100)
Your jump brings you back to the beginning starting with the panel on the left. The problem is how to get the panel off because there is no % at the end of program. You could easily put in some vacuum on/off valve to release the part. Reading this back to myself and I'm thinking I might be crazy or genius. Let me know if it works because I don't want to be crazy. Call me if you need help 909 606-0140

Mike, thank you for your tips. I remember speaking with you when my machine was first installed in 1997, and you still worked for Biesse. Anyway, after thinking about your ideas I thought about a couple of issues that I would have to solve. The program part of this issue would be fairly simple, I would just need the panel parameters long enough in the X axis to activate both zones for vacuum purposes. Locate the coordinates that would run the part in origin 1, then origin 4. Jumping the program as you suggested would make the program continue (as needed) The issues that I can envision are releasing the finished panel (that could be accomplished by creating a type of pry arm to lift the edge of the panel just enough to break the vacuum seal. The second issue I see is locating the incoming panels. Without having the ability of using the locating pins I would have to devise some way of locating the incoming panels. Thank you for your time, and assistance.

I wonder if you can choose mushroom clamps. This way the pedal activates the pin stops. The problem is the program must come to an end or does it.You could also wire in a simple 24vdc toggle switch to the pin stop valve.
