Hi all
Just finished most of my research on these chinese CNC machines. So far this is my conclusions
The electronics are bad... avoid at all costs!
The chassis of these chinese routers come with different weight. (avoid the lighter ones) (30kg) aim for the 50kg+
So have the idea to buy a chassis from yoocnc any opinions of it would be welcomed.
Then retro fit same size stepper motors (4.2 amp) nema 23.
4 x m542 drivers with 4 x nema 23
CNC Kit 4x M542 Stepper Driver 20V-50VDC + 5 Axis Breakout Board Adapter + Parts | eBay
Decent price... and 4 x 23 nema about 110 quid
4 Stepper Motor 3.1Nm Nema23 439oz-in 1yr Warranty CNC Milling Lathe Conversion | eBay
4th axis unit for the yoocnc.
A kress router unit or.. Hitachi sj200 VFD with 1.5kw watercooled (chinese) or preferably german, taiwan or america spindles (if anyone has a list of 65mm spindles please list them)
Power Drive Services - Electric Motor Specialists - Hitachi SJ200
so pretty much a much improved 6040 with better controllers, spindle and power supply.
If anyone else has suggestions on equipment please let me know
thanks
