Hurco KMB-IS CNC update

The only problem with step/dir is that you are adding the "base thread"

This is only true if you are using a parallel port for step/dir, if you are using a hardware
stepgen (Pico, Mesa etc) you only need a servo thread

Leith,

Pete is totally correct, I was referring to the parallel port driver and messed up about the Mesa hardware driver. That is why I am glad Tom and Pete check behind in case I screw up.

I have to run to a jobsite, but will be back later... have to go out of town tomorrow, but will try to get more info for you tonight.

Leith,

I couldn't get on until now.. have been busy, plus some rough lighting again. I have to cut it short unfortunately and get in the bed. I will be back tomorrow night as I will be out of town during the day...

Definitely have replies to make on things I saw... I believe your MPU is different from my original board from what I remember. I have it boxed up, but going to find it so we can compare the two... pretty sure mine had 2 or 3 connectors. Not the AMTS board, but the original Hurco OEM board.... plus I should be able to fine the part number on the board to see if they match.

Also, I would try making a offer to some of the people on Ebay for a used servo that matches up. There was some on there the other day that were exact. That would be the easiest for bolting right in, and stay cheap for the fix.... well that is if they took a cheaper offer. But if you wanted to move on with new setup, then you could keep the Max 430 as a backup for the other 2 still in use.

Also, no on RS-232... going to backtrack after seeing and say its the indexer output. Will get with you... after seeing it makes more sense what you were describing... I was thinking it was like my plug but with the Opto22 cut into the wiring. But no that is Hurco all the way.

Anyway, will catch you tomorrow night... sorry couldn't keep going, not enough time in the day...

No eBay APP ID and/or Cert ID defined in Kunena configurationThe broken motor is Electro Craft part number 0703-02-089.

There are currently three similar motors on Ebay. Part numbers are 0703-02-039 and 0703-02-049.


I suspect all these motors are very similar. But I don't know what the -089, -039 and -049 suffixes mean.

The good news is, my -089 is just a motor generator. The encoder for this axis is on the screw. The Ebay motors include encoders. These can either be removed or simply left unconnected in my application.

So the big question is, does anybody have a 40 year old secret decoder ring for Electro Craft motor part numbers?

LOL you ain't joking about the secret decoder ring... probably stashed at some Tibetan temple in the mountains of Nepal
I just got back in town. I still have some work to do but will be back.

Yes that is the exact auction I was referring to back a few days ago. When you make a offer, I would put in the message to him about the wear, and emphasize that they could be pretty wore already and if the price is high, then you can just put that money to a new setup. Some people are steadfast in their prices and other think about what you state and work with you. I would say it in a nice way like...

"I've been on the fence about making a offer as I have one that is bad... .but hesitate as they are probably like mine and very wore. So I would be throwing good money after bad and could just put that towards a new servo, but I wanted to make this offer as I would go this route if you accept... and if you are not wanting to come down to my offer then I understand and will move on and not bother you."

Most of the time you will get a better response of why you are offering cheap, and not just trying to low ball them.... hopefully it's not setup with a set price and automatic decline as I hate when people setup that way as they don't read your message... then you have to email and hope for a reply.


Will post more in a bit,
Robert
