The controller you need depends on your current needs and/or future needs regarding number of axes, number of IO, and max step-frequency. In general, there are a number of important things that decide the choice of controller. With this overview, we hope to help you understand a little better the different options we offer.
Interface, USB or Ethernet?
The interface to the controller is of course essential. As this determines how
- Easy to connect
- Can also supply power to the board
- Limited length between PC and Controller
- USB interface of PCs are often more susceptible to external interference causing disconnects (buffer underruns)
- Wiring the enclosures with the controller incorrectly can cause ground loops or other EMC/EMI related issue,so make sure you take basis precaution like seperating low-power wires from the high-power cables etc.
- CNC310 (+Ethernet license)
- CPU5B (with ethernet upgrade)
How many axis do you need?
How many axis do you need ? Well most basic machines would need at least 3 axis, X,Y and Z. But wait, sometimes you want to have 2 motors on the X or Y axis (master-slave configuration)...so that means you will at least need 4 axis X, Y, Z and A. If you want in future also add something like a tangential knife you will need another extra axis.
We offer 3, 4 or 6 axis controllers
