Since the answer to the OP question (Is Charter Oak Automation still in business) seems to be trending pretty strongly towards NO. Zero communications by email or phone indicates to me that they...

aaaahahahahahahHHAHAHAHAHAHAHAH!!! So much for the "Patience" part eh? ;)

Jeff, Ben,

OK, that makes sense since it could be anywhere along the shaft. This picture doesn't have the big aluminum block between the motor and the table so I figured that would be where it...

Thank you Jeff.

OK, after a bit more investigation into the "ball nuts" in this mill [it is an IH turnkey mill] I find that this mill can't possibly have what I interpret as ball nuts at all!? ...

I cooked the living **** out of the thing with a heat gun thinking the same thing. No joy. Managed to put a healthy twist in the short end of the hex key though.

It does occur to me that if...

Ben,

The same backlash exists when operating the table manually, at least in X, since that is the only axis with any means of turning the shaft by hand. The X-Axis is reporting ~.002-.003 in one...

Ben,

Yeah, I think the electronics are OK. Anything/everything I've checked seems to be normal and nothing about electronics explains the strange behavior I'm seeing.

Everything that I can get...

Yeah, I'm pretty sure it's mechanical. The control system seems to be working just fine. While it is connected through a parallel port I've not seen anything that leads me to believe it is...

Jeff,

Well after having spent the past week or so on this I'm somewhat at a loss, and wondering if there is any fixing this mill? So much for "just making chips". :tired:

There is some...

Jeff,

The C11 board is not connected to anything? The DB25 connector on the C13 board that wires to its input /output screw terminals has nothing connected to it.
There is nothing connected to...

Jeff,
Again thanks for your assistance. I have determined that this C11 board and associated wiring is not used at all for parallel port operation and I seem to have basic motion and can run some...

Jeff,

thanks for the help on the phone. I think that I have a much better understanding of the situation now and a plan of action.

This is another picture that I'd taken since the others but...

Jet,

Good luck,
Perhaps I just didn't indicate that I wanted to spend enough money with them?
If you do get in contact with them tell them to empty their voicemail box so people can leave a...

Jeff, thanks for the response.
I will try to get some better pictures and post them but these are some that I took initially.
C13 breakout boards on the rear panel of the controller cabinet.

Since Charter oak doesn't seem to be responding to either email or phone calls (mail box is full and not accepting messages), does anyone here know where I might find a copy of any documentation for...

I'm not certain he is making these any more?
