The TMC3in1 has been replaced by the functionally equivalent WarpRunner.
The WarpRunner is almost a drop in replacement for the TMC3in1. The WarpRunner takes less space, uses bettor connectors, has more indicator LEDs and made the J6 Inputs more user friendly. The WarpRunner can do anything that the TMC3in1 could do, only better.
The TMC3in1 is a Torch Height Controller that plugs on top of the ESS, and commands velocity based up and down moves for your Z axis to achieve the optimal cut based upon your settings. This is also a BOB (Break Out Board) that provides 8 additional outputs (for up to 4 motors/axes) and 2 additional opto-isolated inputs.
The TMC3in1 samples the divided tip volts from your plasma unit over 187'000 times per second, and then using DSP filters that down to obtain a stable voltage which is used to command Z velocities to the SmoothStepper 2'000 times per second! This results in very responsive Z motion to help you achieve the best cut quality possible with your hardware and materials.

Other than this documentation, we won't support Mach3 with the TMC3in1. It is not worth our time or your time. Please just believe us and use Mach4 and SheetCam with the TMC3in1. Click here for more info on why.
