A 25 pin parallel port is NOT an RS-232 port! Do not use it.

Serial ports and cables can be either 9 pin or 25 pin or a mixture, but generally serial/RS-232 ports are 9 pin on PCs.

Is your...

You should probably have a better thread title that is more specific and also include a lot more detail and at least a couple pictures

Your cabinet looks somewhat different from all of the Hardinge cabinets I’ve seen.

You should find serial # and then get the machine year.
You should also find the electrical diagram number and voltage(s) of your machine. (Should be on the outside of the electrical cabinet)

Google Maps will find it with either spelling.
They are on the east side of US-101 on Bayshore Rd off the Whipple Ave exit.

I have been checking eBay, but the prices are generally very high and the shipping is also very high.
I’ve also bern checking Craigslist, FB Marketplace, ...

Anybody know where in the SF Bay Area, or Internet with cheap shipping I can find some good deals on good condition surplus/used 3 phase panels, preferably with breakers.

Just for the sake of craziness and as a data point, here’s a 100HP ABB VFD soft starting a 200HP 3ph Toshiba motor using single phase household power.
240V 1ph stepped up to 480V 1ph then into the...

A pony is a good solution to solving the inrush startup current.
I have questions about your 50HP load motor though.
What are you driving?
Are you actually going to use full rated power and...

Yeah, I should have done that!
It was a lot of work even though I purposefully didn’t drive it all the way in and left a couple of feet sticking up since I knew I’d be removing it eventually.
I...

Triangle closed long ago.

Many of the surplus places with store fronts have closed up and/or relocated and are Internet only.
There is a place in San Jose called Excess Solutions.

Thanks!
I appreciate that!
I actually just found a 100W incandescent bulb while in the attic pulling Romex. :-)

Good points!
I like lugs too. As far as neatness, I like terminal strips, but I need to order some larger ones.
Eventually I may eventually sell, and you’re right about keeping it simple. Most...

Interesting!
I’ve never gone there. Too bad it’s closed.
I’m assuming you’ve been to Sims.
I’ve heard that metal prices are way down.
I’d love to find good sources for:

Yeah, I really appreciate how helpful this forum is, and the knowledgeable people who also choose to help!
I wish search on PM was better. I usually find my older/reference PM threads of interest...

Nice job!
Paint looks very smooth. What paint and primer did you use and how did you apply it?

Next things to do:
-fix X axis so it will ref/home (high priority)
-fix air leak near in/near manifold
-clean the machine
-make lots of chips!

-get spring steel BT40 retainer clip that goes...

I debugged and fixed the rotary phase converter problem.

After I spun up the RPC, I powered up the VMC and several times in a row I got servo faults after pressing the on button. I looked in the...

This thread has taken on a good, useful life of its own! Hopefully it’ll be useful for future reference.

Well, I debugged and fixed the problem, which actually turned out to be a loose connection;...

I’ll be the first to admit I’m ignorant of many things, but I am curious and have a thirst to learn and explore and experiment, and I am far from lazy.

I’ll post pictures and more details of the contactor after I’ve pulled it out and had a chance to inspect it.

I’m perplexed because it had been working great for over a year.

I’m going to...

Yeah, I’m going to pull the contactor out this weekend and inspect it, look for where it is damaged.
It has 115V AC coils, so I’ll energize each side and see how each side works.
I’ll try to figure...

Yes, I understand that.
