CNC Router Electronics

[jimmyzwoodworks]

I just finished my first cnc router. Wood frame, Arduino uno, 20mm rods for x and y axes, 12m for z axis, 2 linear bearings for each axis, Nema 23 stepper motors, power supply, and tb6600 drive controllers. During testing, the y axis failed and determined that the drive controller for the y axis was bad.

After some research, I beame aware of the potential problems with these drive controllers and a myriad of alternatives, including alternative drive
controllers and integrated "shields" that include the controllers.

I am a newbie. Not terribly electronically or mechanically gifted. I built this machine to do woodworking - cut out parts, pictures, etc.

What is the general concensus of what I should do if I go away from the tb6600. I've seen suggestions to make my own drive controller (THB6064AH) ,
boards with integrated A4988 or DRV8825 chips, gShield, and g540 from gecko, to name a few.

Money, up to a few hundred dollars, is not a constraint.

Appreciate any recommendations. I am frustrated and just want to get my CNC up and running.

Thanks.

Jim

You need to spend money to get good performance.
At a minimum, I'd look at these drives.

They should perform as well as a G540, for a lot less.

I'm not familiar with any of the Arduino stuff, so can't recommend anything to interface with an Arduino system.

x 2. I have not used them but have had a great run out of Longs Motors DM542a's on NEMA 23's and small NEMA 34's.

I'd try these ones:

Hello.

May I suggest JMC drives? Some models include the power supply internally thus reducing the cost and complexity of wiring the electric cabinets. And also some models allow to fine tune their operating parameters so that you can get smoother and quieter operation.

In my case I use 2DM2260 units and have not yet needed to modify the factory settings. I only use the external DIP switch for current and microsteps.

The motors I use are NEMA 34 1600 oz-in which are surely too big for your application but other alternatives are available.

Regards.
