Tb6600?

[A_Camera]

Hello!
I've had some discussion on what kind of a driver to get and I've been recommended several. It was the debate between the dq542ma, and digital drivers such as the am882 and EM806.
I must say, I've become a lot more educated on the analog and digital driver's. But I'm a highschool student and I can't spend much on a hobby (not yet at least). I hate to sound cheap but is there anything less expensive, and relatively good (meaning it works) for hobby purposes?
I've been looking at tb6600 drivers on eBay and they can get pretty cheap. I've even seen quite consistent good reviews on some.
I'd love to advance to try out the previously mentioned drivers in the future, but they are a bit expensive for me currently. I'm always open to suggestions though too.

( I'm using a 3 axis cnc router with 3amp nema 23's and I was going to buy a uc300eth with some breakout boards) let me know if there's any other info necessary and relevant.

Based on my TB6560 experience I will in the future avoid and drivers based on an TB chip. It may be so that you will not notice any issues, but in my opinion you'd be much better off with the DQ542MA drivers than any TB chip based one. Even if the 6600 is much better than the 6560, I think it is still limited in capabilities compared to the DQ542MA, but sine I have no experience with the TB6600, I can't really say anything else than what is readable from the specs. Regardless of which one you chose, make sure you buy individual drivers for each stepper, and not one board with 3 or 4 TB6600 chips on it.
