Re: Spindle Motor for Bridgeport Series 2 Interact II

Oh, Boy, Jay! I'd avoid that thing like the plague! Chinese, aluminum windings (for sure, painted to look like copper!), under-wound, under-rated, cheap-o bearings. You name it, they HAVEN'T got it on those imitation-just-like-OEM motors. You'd be better off, and spend less to have your motor comple...

Re: Teco FM50 to all in one dc

Jake, there ARE good reasons to stick with it, until you're ready to spend some real money. CNC-sed, "Personally, I would not recommend doing that. Using the 0-10V analog speed reference from the All-in-one DC to control spindle speed through the inverter is much simpler and more reliable. Why use t...

Re: Charge Pump

Although I have not seen any schematics or code to support this, I have the sense that the Ajax board has a "keep-alive" signal that counts on periodic communications from the console computer/Centroid software. I've seen a number of situations where the Centroid control was halted (for whatever rea...

Occasional problem with communications

Scott, et al, I have an infrequent but recurring problem with lost communications between the PC (yours) and the CNC11/AIO. This only ever seems to happen when the system is sitting idle at the main screen, waiting a job start, or after finishing one. I do not remember its happening during a job. It...

Re: completed installations

Wow... sorry... I'm so seldom on-line, I missed this. Actually, no problems, even with the old-style Bridgeport Textron PWM system, except that it was as noisy as heck. It "SANG" all the time, and would nearly drive you out of the shop. The new servos I put on are AJAX's best, still driven PWM by th...

Re: A 'resume point' feature?

Scott, I'm a long time responding to this, although it's been of great help. We've been running the conversion about 35 hours a week without many incidents, most of which were user-caused. (I'll post elsewhere about one problem that recurs fairly frequently). There's one issue with Resume that is tr...

Coordinate rotation system -- a boon!

For those who don't have it, and who do a lot of work with their machines, I didn't know just how much time would be saved by the CSR option until I broke open my chained-shut wallet and bought it. I can tell you - from the standpoint of someone who's mill runs 4-6 hours a day - that the CSR option ...

Re: vfd drive

We converted our R2E4 to single-phase with ease (even BEFORE we bought the Centroid control, when we were still running on the BOSS-9 control). No need to keep that roaring converter going!

Re: Z axis brake

In that same vein, is there a way to only engage the brake after a fixed time delay after spindle-off? Although it works, we don't like the R2E4 spindle brake. It's just too violent. Yet, we need it for tool changes. So, we leave it completely manual. But it would be nice if one could time the appli...

A 'resume point' feature?

I've looked for a way to do this, and not finding one I (naturally) assume there isn't one -- which may be wrong. We work in an area with thunderstorms EVERY afternoon during the summer. Although we can reasonably adequately protect minor electronics like computers and their ilk, we cannot effective...
