Anyone got a good spindle and table warm up cycle/macro that runs for 15-30 mins. I'm looking for a cycle that starts the spindle at 1500 up to 8500 and cycles the table in circles at the same time. My machine sits idle 1-2 weeks at a time and I think it's a good idea to warm up the machine since it idles for some time.
Thanks
You don't need a macro. Just write your own program to move the xy full extent and z from top to some safe level and back. Meanwhile turn the spindle on and then step up as desired.
I have one that starts the spindle at 500 rpm and the travel at 40ipm. Steps rpm to 1000, 1500, 2000, 2500 and travels to 60, 90, 110. Mine runs for about 10 minutes, just long enough for me to get set up and ready to go. May not be necessary but it spreads the lube out over the full travel and gradually warms up the spindle bearings.
Great idea. I never thought of doing that.

I was actually writing a program today just for this same issue. It's not circles but it does move everything pretty good.

Sorry, just realized all my N line numbers are jacked up. I'll fix that and repost. Stand by
Now fixed.
Smokediver,
Why so many M9's all over the program?
You sure are turning off a lot of coolant every line. :confused:
Here's my warm-up program.
It moves the table in a 5-point star pattern while moving 'Z' up & down, and also warms up the spindle.
I use G59 as my warmup home location so I can just keep it in there permanently.
This program repeats 10 times (L10), so it runs for about 10 minutes.
Just change the 'L' value, and it can run as long as you'd like.

Because I'm a total newbie! Thanks for the heads up on the M9 - I forgot I put it in there. Especially since I do not have coolant on the system....Quote:

Nope, I was doing a cut -n- paste from some other known code. This was actually my first stab at manual programming. Ton to learn - took me 2 hours to figure out the whole M98/M99 thing! Like I said, "NEWBI" is my middle name..... or maybe it's my first name!Quote:

I have a 770 so I just adjusted my travels to compensate.

Mine is in the attached zip file. It is big & wordy, because it is part of a big set of subroutines.
N line number are unimportant and not need in a programQuote:

As for table movement on a machine like this if you move it around just to spread the lube that is all that is needed, having it run with a program more than 2 cycles would be just a waste of time, and serve no purpose
I'm thinking the same, but settled on 3 cycles per axis :-)Quote:

Yes that is all a normal machine needs for an axis cycle I would not waste machine time with any more thoughQuote:
