Way skirts question for Iggy

Ig, the other day, I replace the front and rear way covers on my r2e4, because they were cracked.

I selected 1/16" neoprene, medium soft, and the rear one snagged under the lead screw covers -- and tore.

I can't see any significant difference between my cover and the one that came off, except perhaps that the old one is a tiny bit (0.010") thicker, and just a little stiffer.

Your base casting is almost identical to mine. Did you use the flexible skirts on yours (or not change them), or did you install bellows covers?

Maybe you could use thicker neoprene, I think that I use 1/8" rubber. I think that coolant can damage neoprene.

I changed one cover only, the one between the knee and the column.

There, I just used a sheet of rubber. At least I think that it is rubber, I was given these sheets by Mike Henry and I think that he told me that the harder ones were rubber and the softer ones were neoprene. I can take a picture if you want. So far it seems to work fine.

"They" say that neoprene is oil resistant, but I didn't check on vegetable oil!

I think the softness and thin-ness combined were responsible. A stiffer, thicker skirt could not have gotten pinched like that.

Expensive lesson, it was. That darned stuff was almost $50. It lasted two hours.

Not as expensive as crashing bits, though. I've taken to wax-proofing all my parts on the first run of some new code.

OH!

I have a quandry. I have absolutely NO programming information on the Boss-9 extended codes. I'm good up to 89, but there are some 70s codes and a lot of them over G100. Although I've seen a few sample code snippets using them, so far they don't produce the part expected.

Am I stuck with RS-274 codes, only?

Anybody got a programming tutorial that explains the Bridgeport Boss-9 extended codes? The only Series I programming manual I can find stops at Boss-8, and the G170s aren't in there.

Might also be the way it folds and unfolds as the table moves.

Sux!

Whet EMC2 gives me in this regard is toolpath preview, it helps quite a bit.

I think that the BOSS-8 *may* still be using stepper motors as did the BOSS-3 through BOSS-6 and that was controlled by a LSI-11 CPU. (And yes, that was properly spelled with all upper case -- an acronym for "Bridgeport Operations System Software" according to the early manuals.

When they moved to servos they must have had to change the CPU, and probably had the ability (and experience by then) to add lots of extra features.

I wonder whether Iggy's collection of scanned Bridgeport manuals includes the programming of the BOSS-9.

Good Luck, DoN.

No. His collection came from the same sources as my first pass on finding them. Some are incomplete. Some are only two to four pages from

100. All are for earlier machines than mine.

Excepting that my boards are a bit newer than the schematics I have, I do have a pretty complete collection of .pdf and original Bridgeport BOSS-9 R2E4 Series I literature. But I do NOT have the "programming" manual. I found one _called_ that on .pdf, and it turned out the be the Users' Manual -- not the same.

Dry runs over the part with Z inhibit on are a good idea as well.

No, the BOSS 8 is also a servo machine, and uses a Motorola 68000 CPU. Really, a totally different system, with a CRT instead of a row of LED displays. I think that is true of the BOSS 7 as well.

O.K. Thanks. I knew that at least the BOSS-6 was still stepper, but had no idea about when the transition to servos was.

And I like the Motorola 68000 series of CPUs, so I think that would be a nice one to have.

Enjoy, DoN.
