Hi All,
I have recently purchased a pre-owned Sieg SX2L Mini Mill. I very much want to convert this machine to CNC but looking through the forums I found that most of the conversions people here have done have been pretty expensive.
I know most people would recommend hardware from CNC Fusion and electronics from Planet CNC or some other good quality supplier, but I am investigating some more budget friendly options. I was hoping some of the more experienced members of the forums could offer some advice.
Here are the options I am looking at currently:
Controller: New products !!! 4 axis USBCNC with hand controller driver board-in Motor Driver from Industry & Business on Aliexpress.com
X and Y Steppers: NEMA23 270 Oz in CNC Dual shaft stepper motor/3.0A-in Stepper Motor from Industry & Business on Aliexpress.com
Z Stepper: NEMA23 425 Oz in CNC Dual shaft stepper motor stepping motor/3.0A-in Stepper Motor from Industry & Business on Aliexpress.com
Ball Screws: (need to check lengths but something like this) SFU1204 ball screw set : RM1204 L400mm with end machined +SFU1204 single ball nut + BK/BF10 end support + coupler for CNC parts-in Ball Screws from Industry & Business on Aliexpress.com
Stepper Mounts: Free shpping, Stepping motor NEMA23 Mounts bracket the installation Block-in Brackets from Home Improvement on Aliexpress.com
I figure if I can get these parts to work I can do the conversion for about $500 instead of over $1,000 using better parts. Aside from general concerns about quality can anyone tell me why this would be a bad idea? Alternately can anyone reassure me with some reasons why this could work ok?
Cheers,
Justin
