You are probably sick of hearing this but the Gecko G540 is the way to go.
The kit from CNCRouterparts.com with the 380ozin motors a good option. He offers good service and a well matched Driver, motors and power supply. His kit is also plug and play so no wiring knowledge is needed.
It may seem expensive but if you skimp on the driver you will end up with a machine you will curse. It is also the one part you will be moving to your next machine and make no mistake, there will be a next machine. There always is.

If you want to understand why the Ebay option is not a good idea.
The TB6560 driver is one of the cheapest and most complained about driver on this forum.
The motors supplied with this driver need a voltage of about 60 volts so 24 volts isn't going to cut it. The motors will run slow at best.
I'm not sure what Mach3 free offering means but it costs $175USD if you were to buy it, so I suspect it will be the free trial version limited to 500 lines of Gcode, which you can download yourself.


The reason the question on what you are building is was asked is there is no point trying to drive a heavy gantry machine with an undersized motor or a mini machine with a huge motor. First you plan your machine then you select your motor and driver. A lot of people do it the other way around and wonder why their Ferrari doesn't run well with the lawn mower motor they bought on day 1.

If you shop around you will find other solutions providers. In this case though I would suggest to the original poster to not buy anything until he understands the technology better.

The issue with the TB6560 is ( to me anyways) the fact that the manufacture doesn't support the product or revs it properly. Fixes to some of the problems with this driver have been known for years. A manufacture that can't rev a product to meet customer expectations isn't worth any bodies time.

By the way there are cheap drivers that can be had if one is electronically inclined and wishes to do the assembly work and engineering work to get them to do the job.

Everyone doing a budget machine should at the very least consider LinuxCNC. Of course setup is an issue and you get no support.

That last bit was phrased much better than I did. The original poster did respond and indicate a rather light duty machine. So in that respect I don't have any problem with a G540' but your point should be taken to heart, buying to much in the way of steppers is a waste of money.
