Hello fellas. I am interrior design/industrial design student from turkey.(almost graduate, im in my last semester.)

1 year ago i decided to build my own cnc machine and till today i constantly searched how it's made.(at my free time) i learned arduino a bit. investigated cnc types, base and electronic parts etc.
-------------

I'm short for budget(about 700-800$) so, i will built my own cnc instead of buying kits. Didn't design the machine yet.(i will post wip here in distant future)

-------------

planning to build base from plywood. ( i will design it in solidworks. i have access basic woodworking machine tools like drill, tablesaw, handsaw etc. but probably will cut the parts in a local furniture firm's cnc machine. dont have access metalwork machine so machining parts from aluminum not an option. and fabricated aluminum profiles also not an option because dollar have higher value than turkish lira. they are too pricy.)

im thinking the design will be more like buildyourcnc's greenbull machine. > https://buildyourcnc.com/Item/cnc-ma...reenBull-v4-5X
atleast i will be need 2500mmx1250mm active working space. since i wanna build furniture prototypes, i think that will be enough for cutting plywood, mdf etc. and also im gonna make product prototypes from this machine so i will cut plexy styrofoam and ocassionaly aluminum.

since this will be my first machine not need extreme tolerances. (everybody says start with a small machine but i dont wanna)

------------------------
till last week i was thinking to buy chineese electronic kits longs motor or wantai etc. nema 23 425oz 3axis kits with drivers here ebay link
i dont wanna buy tb6560 kits because if one part broken, i have to buy entirely new one. other kits more reasonable cuz if 1 part is broken i can change that for much less price.
i think they will be enough. i aware of gecko drive kits. but its too pricy for me. if i buy gecko than i dont left much money for cutting machine parts from cnc and other stuff.

----------------------

and last week i salvaged a bit of automatic sliding door parts from construction site i worked. and that got me thinkin if i can work my cnc with them.

all parts that i salvaged are: (photos below)
-12x U groove wheels with bearings yellow (rolling pretty smooth)

-12x U groove wheels with bearings white (a little sticky but can work)
-2x pulley belts each 4m long
-1x pulley gear wheel +2 on motors
-various metal fixes for wheels

-1x geared 24V DC 70W motor with encoder. whiterose brand (turkish product couldnt find much info on site. i think its single phase bldc motor but im not sure) has 7 wires on it.> // 2 power red and black // 4 encoder: brown, white, green yellow.// 1 is earth.//
-control box from whiterose motor. i dont think im gonna use that board since its for sliding door purpose, im planning to salvage it's microprocessor for other projects.(arduino related)

-1x geared 80W motor with encoder. dortex brand (idunno voltage, couldnt find info on site i think its 3 phase bldc) has 8 wires on it> //3 power: red, black, white// 5 encoder: yellow, green, purple, brown, orange(pinkish)//
-dortex one has'nt control box.

here are the photos; couldnt upload the forum some reason.

AND Here My Questions:

1. if i wanna drive whiterose 70w motor can i run that with this driver? Brushless Dc Motor Driver BLDC-5015A or any alternative one? i find gecko branded one it matches its pins but its too pricy as i said.
im asking this because that motor have 2 power cable and the driver has 3 on it's specifications ( dc+,dc- U, V, W) im not sure what are they
also encoder cables dont match either i have 4 cable on motor (E+,E-,S,S) written on that motors control board pin. but the driver's hall sensor part has 5 pins (Ref-Ref+HF, HW, HU)

im guessing lefting blank each one driver pins like; motor: U pin andhall sensor HU pin might work but i dont know since im not experienced this stuff i might be wrong entirely that dc drive subject either

2. also can i drive other one 80w dortex branded with same Brushless Dc Motor Driver BLDC-5015A?
this seems more possible because it has 3 power pins on it and matching encoder pins either.

3. if i can drive these motors from any drive, will it enough for any cnc axis?

4.im aware im gonna need atleast 1 more axis motor and controller so are whole thing worth trying? should i give up trying work these sliding dc door motors and just buy 3 axis stepper motor and driver kits?
right now im convinced myself that i cannot control effectively these dc motors. but if you fellas help me to find a way i can try

5. if sliding doors doesnt work, does 3axis nema 23 428 oz motor enough for 2500mmx1250mm workspace cnc machine? or should i go for nema 34 kits (reminding that i dont need too much precise and speed)


unreleated and other suggestions about design, electronics, material selection production and pro tips are wellcome too, right now im considering everything. :=) appreciate any answer.
