Need help setting up a lathe(Sherline)

I am planning on controlling a Sherline lathe with Linux CNC. I will be using the Sherline Nema 23 motors, and I have a computer. What else do I need? I see Sherline has a '4 axis driver box', but I think that is expensive.

Unless I am missing something, I only need 2 axis, but I am not really seeing much labeled as such, lots of 3 and 4.

I also see driver boards, breakout boards and power supplies, I am not sure which of these I need.

I am thinking I can just initially set up the motors to whatever to play with Linux CNC and when I get everything working connect them into the lathe.

Hi
you can go very low Cost
What budget do you got or expect
4th Axis is a standard board
in modern times a Ethernet woudt be best
there are a 7i92 Interface that fits the sherline
but with a PCI parport card at 20USD is also a good respons

do you need to build the box or is the sherline box alredy installed

You would need
Breakout card(there are some on eBay for as low as 6 dollars)
2 stepper drives(1 for each axis)
2 steppers
1 switching power supply( will support 3 drives some are adjustable for voltage)
Some 18-22 gauge wire.i used 18 for power and motor wires and 22 for limit switch.

Motor mounts,
Sherline has a couple CNC kits, I think they have one with just adapters for bolting up the steppers.

Also if the PC doesn't have a parallel port will need a paraport card, and cable.

I have only ordered the steppers at the moment, and have a computer to use for it.

I am trying to figure out what else I need. I am overwhelmed as it seems there are a bunch of configurations and they are all different. If the 7i92 Interface is a good option, I'd hopefully be able to use the ethernet port. What else would I need? I am guessing a power supply, but don't know about driver boards or a breakout board.

I have this one(one like it )
rover.ebay.com/rover/0/0/0?mpre=https%3A...2Fitm%2F282099594144

A Chinese power supply from Amazon
You could probably use a lower voltage one a little less expensive

if you are on budget high
use the 7i96 it brings all the needed direct connect
while the 7i92 is always a double component option and has the most side tricks to go on further mashine action

BUT you can go for the First and low cost setup on standard components

WHAT steppers did you order
and why dident you consider the 2Nm Hybrid in first place very tiny high speed and best precision

I have these, www.sherline.com/product/67127-stepper-motor/#specifications

I wanted those since I know the dimensions would work and other have used them while manually using the machine as well.

manually using the mashine while steppers/DYNAMOS are connected is quite a chellenge for the Drivers
Analog drivers like D542 may produce 150V towards the electronic while turning the Spindel manually

be aware of that you can get nice quick connects between them it is nor a good work but safe
and you will fast realy fast find out you mashine no longer needs manuell as of subs on the controll will get you fast into conture

I know I would need to disconnect them to do any manual work. I just want the option in case I need it. I am just starting out.

Do they sell the female side of that connection? It would make wiring it easier.
