I am building a Kyo C-Beam Sphinx. Mainly for wood some aluminum (building plates out of mdf then using the machine to make the aluminum plates). I had originally wanted to design a machine that I could use to carve aluminum molds for lead fishing lures as well as various wood projects, but quickly realized that would not be doable on my 1k budget, so am settling for something that can handle simple alu plates and wood. Originally my plan was to get nema 23 high torque with the tinyg or the cnc xpro (not sure which yet). I like that I can plug in directly to Mac and don't need a secondary computer and that I can use free open source software and it has pwm for my spindle controller. When I finished designing the frame and looked into the electronics I realized that the tinyg can't drive the 3a the nemas needed. So I considered the DQ542ma from the part store but this is out of my budget because I will need 4 of them which is another 160 dollars and I am already at my 1k budget with the nemas and the tinyg. So I thought ok ill downgrade to the 170oz nemas, but I see they need 2.8a so the tinyg still doesn't work. So I started searching around and found some sets that have the motors, drivers and the power supplies, & controller. Like the wantai motors on eBay and the sainsmart sets. Problem is the wantai comes with a serial port controller so there goes using my Mac, I would have build a linuxcnc machine to complement the cnc which I do not want to do and no spindle control. The sainsmart sets all come with a mach3 board so that means I would have to buy mach3 thus negating the savings. So I researched some more and found that (if I am understanding correctly) I can use either nema23 with the tinyg it just won't receive more than 2.5a but it won't damage them. So my question is should I use the tinyg and undercut the nemas or does anyone know of more affordable driver options that I have not found? Because everything that I looked at that can drive the nemas is out of my price range. After the frame and the spindle I have about 330 to spend on the controller, power supply, steppers and drivers if I need them. thanks for the help and if I missed a post with these answer I apologize please share it and ill read it to see if it helps.
