Electronics for Hobby-Line 6045 from Sorotec

[hardenum]

Hi I recently purchased a Hobby-Line 6045 from Sorotec and a Mechatron 1.5 kW spindle. It's gonna be my first time owning a cnc. Originally the kit is bundled with

AMB FME-Q 800
NEMA23 1.8Nm
Lichuan MC542 drives

I thought I'd instead get:

Mechatron HFSAC-8015 1.5 kW spindle https://www.mechatron-gmbh.de/typo3c...015-24_web.pdf
Nema23 3Nm https://cdn-reichelt.de/documents/da...3-03_DB_EN.pdf
UC300ETH-5LPT

After some research I decided to go with UCCNC. Cam is Solidcam.

I saw some recommendations to pair the UC300ETH-5LPT with UB1 BOB or a Gecko540. Honestly I have no idea what to look for. I mostly want to mill aluminum alloys, nothing fancy, the regular stuff you can get on ebay.

What about the drives? A DM542?
Breakout board?
variable frequency drive for the spindle?
PSU?

Thanks!
