If the C axis rotates from a position of C-23.0 degrees to a position of C-60.0 degrees, then it is moving in the negative C direction. Let's say that is CCW from your viewpoint. Then when the C axis rotates from a position of C-60.0 degrees to a position of C-23.0 degrees, then it is moving in the ...

If the asterisk is always visible while you move the axis up and down the scale, then yes: you should try swapping the polarity of the index channel wires.

But, since he has defined INP6 to be a normally-open probe-detect input, and has set P18 = 50006, the software should recognize that the probe is not available to be tripped when INP6 is open, and in that case ignore the state of INP7.

If you have +24VDC wired to your input bank common, I would call those "sourcing" inputs. The input sources current; the sensor wired to the input sinks current. If you have 0VDC wired to your input bank common, I would call those "sinking inputs. The switch or sensor sources current;...

If you are not using M8 for Flood coolant, and you want ready-to-use PLC support, macros, and VCP buttons, then just call your air-blast output "Flood" and go back to using the factory-supplied files.

M26 /X Q1 G00 X0 M26 /Z Q1 G00 Z0 Of course, if you power up the machine and run this sequence while the tool is overlapping stock in the spindle, then it will crash. Also, if the currently active tool offsets do not match the tool that is currently in position, and there is stock in the spindle, t...

What is the brand and model of those replacement X limit switches, and where did you find them?

Looks good.

At the MDI prompt, you can use the up arrow key to recall previous commands, so you don't have to retype them.

The C axis positions are positions, not incremental distances. If all of the work happens to be on the negative side of C0, then all of the C coordinates will be negative, even though the C axis does move in both directions. This is for the same reason that all of the Z coordinates are negative, eve...

I think his machine has the original HNC/CHNC configuration, with the encoders mounted to the ends of the ballscrews. Since the reasons CNC12 needs to to know "motor revs/inch" are really to know how many encoder revolutions to expect in an inch of travel, his would be set to 5.0000 regard...
