Hi Tom, I'm Edgar from Mexico. I acquired the THC SD proma and I've installed a floating head for the location of the material, everything works fine. I had problems regarding the location of a reference point after making some cuts, as the THC SD LinuxCNC not communicated the adjustments made at the THC axis Z. This is a problem because there comes a time that adjustments exceed the value of the axis Z. I'll try to explain what is happening. I have installed a switch that tells me the value of a known point on the displacement of the Z axis, this point I use it as a reference to the end of a sequence of cutting locate this point and reset the value I need to commute to the next route cut. for example, start the cutting operation and assuming that the material is at -22 mm, there I set offset in Z, then put it to a height of 2 mm which is the height of cut in the coordinates of the machine would value at -20 mm, assuming the THC fits along the cut 2 mm, ie at the end of the cut the coordinates would end in -18mm, but since the linuxcncn not get this setting, interprets this at -20 mm the end rather than 18 mm as it is real. Thus adjustments are accumulated until the total exceeds valid displacement for the Z axis and at some point it will send an error that achievement does not reach the benchmark. annex the two functions I did for before starting the cutting sequence (pre-cut) and the other runs the fnal of the cutting sequence (recut).
I tried that sequence will realize home after each cutting sequence to reset the reference point has moved. Any idea that you can send me I'd appreciate it very much.
