Newbie: connect servo drive to computer cheap

Todd Zuercher wrote: Those Clear Path motors/drives (They are a motor with drive built in.) can be driven directly from a parallel port, but using a breakout board is advisable. If for no other reason than to give you an easy way to connect cables together. But isolation and voltage correction (converting a 3.3v signal to true 5v) are worthwhile benefits that an inexpensive breakout board can offer.

Silly me. Turns out my computer does not have parallel port. Lol, when those stopped being standard?!?
Breakout board its is. An recommendations?

I recommend using a break out board so your PP or computer does not get damage if something goes wrong.
I also recommend getting a power supply that will run them at full voltage 75vdc, I would get at the minimum of 10 amp so you will have some over head.
This is what I have. with the 5 and 24 volt option.
No since sending $$$ twice , Only if you want to.

Thank you for references.
Can you please elaborate why 1/4" shaft is proffered?
Also why 2310S moles is used vs 2310P or 2310D? Is it because of more torque?

I am using this one with 1/4 shaft for my "Z" axis And when I purchased it I saw that the 1/4 inch coupler is easier then the 3/8's coupler to get, The other two I have , have the 3/8 shaft, This is for X and Y. They are a different model #
The 3/8 shaft coupler will hold more torque.

Why the 2310S, Like you said, Yes more torque for the same $$$$$

You might have a 26-pin header on the motherboard but no back-panel parallel port.

Which motherboard is it?

If your computer doesn't have a parallel port (or a header for adding one), then you can add a PCI or PCIe parallel port card, or buy something even better, like something from Mesa.

I checked. There is no connector like that on my motherboard.
So I'm going to spend money on breaker board it seams.
from what I'm reading there are boards which connect to PV via USB, Ethernet and parallel port ( in which case I would have to buy some PCI or whatever card I guess). And there were some comments online that USB is less desirable because of some less real time blah. and I'm assuming ethernet is similar thing plus some lag maybe. And comments about LinuxCNC philosophy being to keep all controls and decision makings in PC as opposed to FPGA where control is outside, Yet I see lots of cards on Mesa which are FPGA and supported bu LinuxCNC.
I'm struggling to make sense of all this. Would you know which way is world going and what is the preferred way to connect nowadays or in the future? I got to figure out which card to buy somehow.
