My pick is that a quality USB cable will fix it though, worked for me.Ĭlick the link to add information to this solution: I have your USB controller sitting here and want to control it with something other than PlanetCNC control software? Alternatively you may need to sheild your limit switch, estop and or motor cabling. In the first instance try to use a quality double sheilded USB cable, hopefully this will fix your problem. Additional Information: Additional Information: Additional Information: The planet cnc controller can be prone to electrical interference and has been known to cause such problems. The price combination is much higher than the USB controller with planet-cnc, but will work with Mach3. Second, if you have a laptop, or really want to use the USB as the main interface for controlling the machine, you will need to get the smoothstepper board which works with mach3. If you have a laptop/notebook computer, this will not be possible. There are two main alternatives if you want to use the mach3 software: First, get a parallel port card and add it to your computer and get a parallel breakout board. The planet-cnc software delivers instructions to the microcontroller on the board and the microcontroller will send out the pulse trains needed to move the machine correctly. This software is well made and will provide great functionality. The USB controller will only work with the Planet-CNC software. Where do I connect that on the controller board? If you use this method, you'd essentially wire the e-stop as a limit switch.Ĭlick the link to add information to this solution: I recently purchased 3 axis electronics with the USB controller board. Our website datasheet for the USB board is at and shows how to configure the switches for each set up. The wiring would depend on whether and how you might be using limit switches (single or multiple switches normally open or normally closed). Alternatively, you could use an input pin on your USB board. Here is a diagram showing how a customer wired such a switch on their blackTooth laser which you could adapt to your needs. The simplest, and arguably the most certain, way is to wire the switch into the incoming power so that throwing the switch kills all power to every part of the machine.
There are many ways to wire an emergency stop switch.
