Considering a build based on Avid Pro frame 4x2. My current CNC uses a Windows machine with UCCNC and a custom screenset by , which I moved to after bad experiences with Mach 3. I’d like to liberate myself from Windows and proprietary software, plus moving more of the motion control into a dedicated controller makes sense. I’ve heard good things about GRBL for all these reasons, despite its limitations.
I’m interested in anyone’s experiences here. Which combined controller and stepper motor driver boxes to use, which software has worked well. My current setup works well, so I don’t want to move backwards, but it has its limitations as well.
I would call and ask them directly. I use their motors in all of the products I make (even the tool carousel will use 3 of them) but I can’t sell them directly so I just funnel everyone over to them. Pick up the phone and somebody will help you better than I can.
You would be using the Teknic SDSK line which do not offer that function. The GrblHAL boards and most low cost controllers do NOT offer closed feedback communication, just step and direction. You have to get into their Meridian line of controllers before you get things like G-Stop and spline based smoothing. All of that is rather expensive.
You can set the SDSK motors up to report extra data using their HLFB / Status pin and use an Arduino to interpret the data. It offers things like torque and revolutions (one tick per) etc but nothing that would improve your accuracy.
The SDSK are probably the best steppers on the market, period. But they are expensive.
Yes, you will tear up the pinion gear real quick if you don’t set things up correctly. Unlike a ball screw, that rack and pinion can slip and when it does it will chew off the teeth on that pinion gear.
