I have just completed my cnc router and cut my first job which is great.
My problem is the max speed I can get which is only 500mm /min.
The motors and controller I purchased from eBay the controller is a TB6560 ,power supply is 24 volt 15amp and the stepper motors are Nema 34(34HST9805-37B2) ,I have attached a spec sheet for the motors.
Currently i have them wired up as Bipolar Series which i will be changing to Bipolar Parallel to increase speed.
What I need help with is from my calculations on the motors is that if wired in Bipolar Series the motor will require 247 volts @ 1.4 amps for full power and if wired in Bipolar Parallel it would be 124 volts @ 2.8 amps could someone please confirm my calculations thanks,.
If this is correct I should be able to get a large increase in speed by changing my controller and power supply as my current power supply is only 24 volts and the controller can only handle 32 volts Max.
I was looking at the Gecko G540 but its Max voltage is 50 volts which is double what I currently have.
I would require a 4 axis controller as my X axis uses two Nema motors one being slaved .
My other option would be gecko G201x drive which can handle up to 80 volts but as far as I understand I would need 4 of them and a break out board which would cost a lot.
Any suggestions would be greatly appreciated.
