I'd say you've helped more than I could have expected. My board is evidently the older version, because there is no jumper for pin 13. Thanks a bunch.

Does that mean adding a resistor externally? The probe did work, by the way, when it was connected to pin 11, and none of the remaining input pins were being used (all the limits de-activated).

This isn't the probe from Keling, by the way. Theirs does look a lot nicer than the one I bought.

Actually, the probe is N/C. Touching the probe breaks the circuit. That's somethng else that's always been a puzzle to me. According to the board instructions, the input pins require 5v to create an input. Another board that I have connects the input pins to ground. The probe instructions say to connect the probe between an input pin and ground.

I'm trying to use a digitizing probe, and it won't respond using pin 15. Pins 11,12, and 13 were hooked up to limit switches, so 15 was the only one left. The probe would only work when I used it on pin 11, but then I couldn't get the limit switches to work on the remaining pins. For that matter, pin 15 doesn't work at all when 11,12, and 13 are being used.

Thanks for the help. That's the first piece of the puzzle solved. Now if I can figure out why it's tripped.

Can anyone explain the cause of the message "Probe ignore, activated at call for probe" ?

Has anyone had any experience using the C10 breakout board from Keling Tech?

G-Code, CAD, and CAM discussions / Z axis crash

« on: November 23, 2011, 04:36:13 PM »

I am using Bobcad's postprocessor. It inserts the following line into every program "G53 Z0.", which causes the Z axis to plunge down into the table until it crashes (the top of the part is supposed to be zero). What's the purpose of this command? I have to go through every program and delete it before I can run the program.

No brains. I don't even know how to use them yet.
