Spindle stopping when warming up!!!!

[dubliner]

While I'm messing about in the shop I warm up the spindle, I'm running SB 3.6.5 and after about 5 minutes, it seems like its always 15k, the spindle will shut off, no error messages whatsoever. I have the spindle control installed. It doesnt ever happen when I run the machine or cut a long 3D file, just when its sitting & warming, any ideas? TIA Dubliner

My does the same thing. I been trying ti figture it out yet, but working on it. If you find out let me know. It didn't start this till I installes 3.6.5. So it may be in the software.

Neville...
You are using a version that had some issues. There are less in the newer versions. Try 3.6.14

tx Gary, as usual. I owe you a few pints :-)

Free Pints?
If your buying, I'm stayin...........
I have random days when my colombo spindal cuts out mid program 10 times in one day!
Then, it does not happen again for 4 months!
What the heck?

Any sugestions?

[frank134]

I have install 14 and still have the same problem. What I do how is start the program and start the spindle and warm it up from their. gary from 5 up it has done this.

Gabriel, what I suggest is that I meet you at the Maker Faire in SF, and leis ceol, caint agus craic we can figure it out :-)

I've copied other peoples warmup programs that have been posted on here in the past and they just don't work on my new style Alpha.

It won't recognise the speed changes after the pause unless I put a SO,1,0 to stop the spindle, a 10 second pause, the TR command for the new speed and then the SO,1,1.

If I just try the usual TR xxx, PAUSE 120, TR yyy it either ignores it and carries on at the same speed or stops at a random interval.

Works fine when cutting jobs but then I don't tend to change speeds during a single file.

I've tried all the 3.6.x versions, I'm currently on 3.6.14 and it still does it.

It's not a big deal to me as the warmup file I use now works perfectly, it's just a bit weird that it doesn't work the way most peoples do.

Spindle warm up.......
Could this be accomplished with a heat lamp?
Are we talking ambient heat or is something else going on requiring spindle warm up?

Chuck,

Before you start creating chips and sawdust you need to make sure the bearings in the spindle are warm. Putting side loads on the spindle without proper warmup shortens the life of the spindle bearings.

Thank Don!
I get the picture which takes me back to my earlier question of an exterior form of heat source.
I've learned all about B-10 bearing life in my former life.
Perhaps preheating the spindle is no big deal with regards to time but the shut down thing for no reason is curious.

I'm amazed at the amount of things users report here that cause the bot to run contrary to the operator's desire.
One of the CAD program I own has a list of all the error codes the program can produce, a brief explanation behind each error code and possible solution for resolving the dilemma. In my case, most of the error codes are operator error. However, the ability to look up the error code and educate oneself on why the error codes exists in the first place gets you back running.

Does something like this exist with a SB?
For example, very few of us know the ins and outs of the vehicles we drive. When they mess up, men, who used to be able to repair anything are reduced to dragging the car to the dealership to plug it in to find out the error code means mice nests in the air cleaner.

Seems to me a code book needed with an "IF This" "Check This" section.

My 2¢.

Dr ShopBot is a project that we hoped would serve that purpose. It's been a struggle to keep it up-to-date but does help solve a lot of the more common issues that ShopBotters come across.

Thanks Bill!
Didn't know about Dr. Shopbot.
I hope my comment read as productive and not critical.
A hammer and chisel in the hands of some people can produce works of art.
In others, gravel.
Perhaps the same with a bot?

When I am stuck I send off a email to the villains. No sooner do I push send when I figger out the problem...and it is mostly operator error.

Hey Chuck,

Don't worry...it was taken in the spirit it was given.

FYI, there's a webpage that lists a bunch of ShopBot-related resources and projects that might be interesting to check out:

Upgraded to 3.6.14 today and my spindle warmup routine stopped working. Don't know why but I'd like it to work again so I don't have to manually up the spindle speed after each 120 second pause.

I've sent an email to Support.

Don, that sounds exactly like the problem I'm having. I did report it to support a while ago but haven't heard anything back yet.

After a lot of experimentation I wrote a working warmup file that I've attached. I'd be interested to know if this works for you to as it would definitely confirm we've got the same problem.
