Hello,
I'm lookin for some help in setting up my Tool Setter in Mach3/MSM.
I have :
Win XP SP3
Mach3 .066 (Licensed)
Using CNC4PC C10 Rev 11.1 board for inputs
I Have a 5v DC power supply, (saw online that 5 to 24 volts will work)
Using the SK-66A-KC Tool Setter with N/O contacts for tool touch (Red & Grey wires) = Works OK
(Blue & Green wires) N/C contacts for Over Travel = Works OK

But I'm curious as to how the (Brown & Orange wires) are to be wired/used? Is there an built in LED that would light up?
I have the wiring diagram (see attachments) but by no means am I an electrician???

Thanks, MegaMoog

Hi,
Well, the schematic is not real clear. It ***may*** be an opto isolated output for the NC contact. The schematic does not use the usual symbol opto coupler, though it's similar.
I suggest that you contact the vendor of the sensor for more information and support.

I'm sorry, but decoding 3rd party schematics and interfacing a non-documented Chinese device to a different vendors breakout board is and electronics design task, which makes it not something that we consider to be part of free MSM support.

Hi Larry,
I've just bought a very very similar unit; it arrived last week. $65 shipped I think.
Includes the air blast. I first saw this functionality on the Tormach one, but it was too pricy ($900-ish I remember).

Mine did not have an LED; but this is not important to me.
Mine was just 4x wires. Two NC switches. One at the top of the travel. One at the bottom of travel. Planning to wire the overtravel switch in series with my 3rd e-stop channel (with all axis over travel switches, and thermal cut out to spindle). And wire the main switch as an input to Mach3. Should be really simply.

I'm planning to wire it all in in the next 2 weeks + write the macros to do the air blast + auto TLO within MSM.

I installed the relays + solenoids tonight, so that's the hard bit done.
I'll make a short post when it's all complete and working - shouldn't be too hard.

Hello,
Thanks for looking at the schematic even though it did not scan well!

I kinda new/figured out that the (Brown & Orange wires) connect to the same pin outs as the (Red & Grey wires) do!
I just could not see the LED come on with only 5v. I turned off the light above my work bench n pressed the tool setter down n I could see a very dim light.
I might get a 24v power supply n use that for the Tool Setter n Probe. Use some resistors on the home/limit switches for the X, Y, Z, A, & C. (Not that I need the light but I thinks it would be kinda KOOL!)
That's one of the reasons I like using the MSM screen in that it has the second pp port on the setting page which helps in setting the pin outs for the connections.
I will be using the pins 2 - 9 and 10 - 15 for inputs on the C10 board via my second pp port.

Now I'm workin on getting the Z axis trammed n will be mounting the A & C axis trunnion...

Time to get back to the Lab n do some experimentin.....!!!

Not sure how to add the air blast just yet but if ya get something put together Dan maybe I can get some help on that?

Thanks n hope this helps somebody thinkin of using one of these or similar units.

You want to look at the "Pre and Post AutoTLO Measurement" section of the user manual.
