The 10K resistor goes from where to where? I have done some searching with no luck

Thank you

well i answered my own question after contining to search. The resistor goes between the plate and pin # 10. I have configured that as an input. Now where do i pull the +5 volts from?

I referenced this post for picking pin #10. http://www.machsupport.com/forum/index.php/topic,12742.0.html

The resistor is used to pull-up the voltage on the the plate to +5 so the resistor goes between the plate (pin10 ?) and +5 volts. You could get the +5 from a spare USB socket if you have a USB lead you can cannibalise.
When the tool touches the plate it should then make the plate (pin 10?) zero volts.

Pin 10 is what i found the other post. I assume I can use any in put pin? Or is there a preferred pint to use?  I'll scrounge up a USB to take power from.
Thanks

Craig,

Any input pin# is OK.
Whichever you choose has to be configured to Probe in Ports and Pins.

Ok, I have moved on to actual functioning of the setter. I have used Tweakias seggested script from another post. It moves the Z axis no issues. Now i have also tested that the led would either come on or go off depending on its active state which it DID NOT. I hought possibly my circuits were not complete (soldered properly) or wires to long. I have checked with a multimeter and all seem well less one. I have no continuity on the plate wire after the 10k resistor(it may be too large). I did try jumping to pin 10 after the resistor no change.

As an experiment i jumped pin 10 to what i beleive is USB plug ground. Doing this the digitize LED came on or went off when jumped depending on active high or low.

I feel i'm right on the cusp of having the setter work properly just a set up issue at this point. Suggestions are much welcome.

Thanks you again

Hi Craig,

Sounds like you are almost there.
Your current problem seems to be with GND. The cutter should be at the same potential as your USB GND, that way when the cutter contacts the plate the digitize LED illuminates.
The resistor does not go in series with the plate. The resistor just connects your pin 10 to +5 volts, then the plate connects to pin 10 as well.

Hope this helps,

Tweakie.

Does pint 10, +5 and have to wires in any particular configuration or just end end up together?
From what i could find per USB pinout Red is +5 and black is GND.

Well so much for going to bed. more work to do.
