Mesa cards or parallel port? And where to learn about Mesa

Hello, 

First time poster so please go easy on me.

A friend of mine donated an industrial PC for my CNC lathe conversion. however, there was unfortunately some miscommunication and the multiple parallel ports turned out to be serial ports and no PCIe slot. 

There are a couple of Ethernet ports which I understand I can use for mesa cards. I had planned to use a parallel port for simplicity as mesa cards have been very intimidating (I can machine but electronics scare me) I would appreciate hearing people's thoughts, buy a new PC with a parallel port? or stick with this very nice  machine and go for mesa?

I would also be thankful if anyone could direct me to resources to learn about Mesa cards. I have found so much information but am struggling to find really comprehensive information at a beginner level.

Thank you all for your time any help would be amazing.



 

I prefer Mesa cards because of their reliability and lower demands on PC latency. Studying Mesa cards is difficult for a beginner. It's easier to write what you need here on the forum. Then you start studying the instructions of the recommended cards. The hardest thing is to understand the first Mesa, after that it's easy.

Go with mesa 7i96s
Nothing to learn initially.
Just build a config with pncconf

Thanks, that's very kind for you guys to suggest a card, I'm sure it's being asked before. @rodw suggested the 7i96s, would you concur? I've seen it mentioned a lot I've just no idea how it differs to other mesa cards in terms of it's capability.

For now I'm controlling 2 closed loop axis and the VFD however in the future will add a spindle encoder, tool changer and potentially coolant. Can that be done on the 7i96s or is another card, or expansion card required?

Thankyou

Thanks this is really helpful. Especially giving me the name of a PC, trying to search for machines with a parallel port has been pretty tricky.

Is there a learning benefit to starting with the parallel port? I have set aside a nice budget for this conversion so could spring straight for the mesa, I'm getting the impression I shouldn't be scared of it.

Beyond the card, power supply and cabling am I right in thinking there isn't any additional cost to it?

Thank you

I managed to bypass parallel port and go straight to Mesa.
There is a lot more gotchas between you and a working config than the mesa card.

Thanks everyone this has been really helpful, and I feel much more confident knowing there is a nice community willing to help. I'm going for a 7i96s.

I was just wondering if anyone knows a good way to get one of these cards to the UK, the shipping isn't insignificant.

Thanks again
