Hello,
can you please help me to choose electronics for my CNC. I was looking all over the internet about that and the more i read the less i know. Everything looked so easy at the beginning, but now looks like nightmare. I already spent half of my savings so i can't return now or quit.
I already bought mechanics for my CNC. Table size would be around 1200 x 800 x 300 mm.
I was thinking to buy nema 34 motors. Motor specifications are: 5.6 A/phase, 4.1 mH/phase, 7.7 Nm or 1090 oz-in, rotor inertia 1700g-cm2, 4 wire.
Drivers for that are DQ860MA, and power supply 350W, 60 VDC for each motor.
Can you tell me is that ok? Is the motor strenght enough for table with dimensions from above? I would like to mill in wood, aluminum and other soft materials. Can you also help me with driver settings. All those microswitches... i don't know where to begin. What current, how many microsteps...
Sorry for grammatical errors, i am writing from Croatia.
Regards, Domagoj
