General Mach Discussion / THC Settings in Mach
« on: September 23, 2011, 12:13:27 PM »
Hi;
I'm about to build a height controller for my router. I'll be routing plastic that is irregular and need to be able to follow the contour. In reading a number of posts, the only way this is likely viable, at an acceptable feedrate, is by using the THC Up/Down inputs to Mach.
I'll be using a shoe that slides on the surface that causes a linear resister to change value (I'll be using a HotPot from Spectra). This will be processed by an Atmel AVR that is then interfaced to mach.
I'm trying to find detailed info on the process flow that mach uses for the THC. There appear to be a number of settings and inputs/outputs that relate to the THC control, but I can't seem to find any in depth explanations. An explanation of the settings and how they interact would be truly appreciated along with any thoughts from the more experienced Mach gurus.
Of course, I want to implement an easy to use system that utilizes Mach to its best advantage. I'm open to any thoughts, suggestions, pitfalls or wild ideas
.
Thanks in advance.
