Frage looking for pinning internal 26-pole header...

Hi,

I'm looking for the internal pinning of the Stepcraft. I think I saw a schematic somewhere on the forum, but I'm not able to find it.

Basically what I have found so far is:

1 Spindle on/off OUTPUT
2 DIR X
3 STEP X
4 DIR Y
5 STEP Y
6 DIR Z
7 STEP Z
8 DIR A
9 STEP A
10 Toollength sensor INPUT
11 Emergency stop INPUT
12 HOME X/Y/Z INPUT
13 HOME A INPUY
14 COOLANT OUTPUT
15 ?
16 ?
17 ?
18 GROUND
19 GROUND
20 GROUND
21 GROUND
22 GROUND
23 GROUND
24 GROUND
25 GROUND
26 +5V ?

I hope someone can fill in the gaps and/or confirm the signals please ?

Thanks in advance

Guess your labels are from PC point of view and not from SC header point of view, otherwise I and O are swapped.

SC Machine parameters

Hi,

Uhh, I think your right

I'll will double check, but do you perhaps know whether the signals are correct and/or what the missing signals are ?

Pin 17 (PWM) is used by the HF-Spindle to control the rpm (in my opinion).

You should look for the Arduino Shield in this forum there could be more information.

Hi,

Thanks, I'll look. I'm sure I saw somewhere in a thread more info... Should have marked it

You understand that the words written in orange are a link to a PDF listing the Pinout on page 2, first table?
