@Chad_Nuxoll , you’re a smarter man than most people I know that have jumped into 3D printers lately. Doing your research…such a novel approach lately. 
@ThantiK O well thanks. Just trying to learn as much as I can really enjoy the hobby and the idea of 3D printing. Always learning though :).
@Wolfmanjm Ok relays are not hard to put in. Never heard of a SSR though
After looking at the Azteeg X5 I think I might end up changing my controller. So going to be a noob here but on my last printer I never even heard of changing the jumpers. Are you suppose to match the steps with your motors
Yes those are what im using on my delta. They also offer the 1.8 deg motor as well for tge same price of 15.00 each.
As for resolution I love the quality of my .9 motors. They are the same price and do provide better quality than the 1.8. Maybe not to 100 precent of what they could be capable of but there is no cost difference. …
@Chad_Nuxoll Not sure which jumpers you are referring to, but on the X5 you can set the microsteps, and you can choose whatever you prefer, I like 1/32 because it is quieter and smoother.
On the Azteeg X5, this wiring diagram shows in the top right where to change the step size. at bottom is a table that shows which combination gives you how many steps.
@Wolfmanjm I bought a kit for my i2 and it came with a Sanguinololu 1.3a and it came with the motors. After looking, it only has one jumper and ive never noticed it haha. I was going to ask you it has built in stepper drivers so do you go into the smoothie firmware and change the current or how do you change that.
@Richard_Turnock Ahhh that would make it easy to change. So if I bought the X5 does that mean 0.9 deg motors is a good choice. In a earlier comment you said that wouldnt work together good i think is what you were saying.

Can get something to you fast.
@Chad_Nuxoll You set the stepper current in the config file for smoothie, no pot twiddling needed.
+Chad Nuxoll people buy the X5 to get the 32X stepping. Someone with experience using a 0.9 degree motor should answer your question.
I have seen comment on Google discussion forum where guys had 0.9 motors and had to change the stepper driver back to 16X
We are all pushing the limits of the technology trying to find the best combination of parts to make a reliable machine.
What ever you choose, just know that the innovation is moving so fast that what we write here now will be obsolete in 6 months.
The X5 is much faster than Marlin/Repetier. It can issue over 100,000 steps/sec compared to an arduino which can do 30-40K steps/sec. So it can easily handle the steps required to drive a 0.9° stepper driven at 1/32 microsteps.
