No Z movement when THC is active
« on: March 28, 2015, 10:13:34 AM »
I am using a THC and the inputs are receiving the up/down and arc OK commands correctly (the thc lights in mach are lighting up) but the z axis is not moving. I set the thc limits to -.5 and 3". I can jog the axis with both the MPG and keyboard. Is there a setting I am missing? Any advice ya'll can give?

Figured it out. Great email support from warp9td (makers of smoothstepper boards).

USB Smoothstepper does not have the firmware for THC. The FPGA is smaller than the Ethernet version and is at 99% full. The Ethernet Smoothstepper has an option in the configuration Dialog that supports THC function in the Ethernet controller only:



Of to order a Ethernet SmoothStepper.
