Hi Bill,
Ok!
For the length of the temperature sensor, splicing in about any 24gauge wire or thicker should be fine,
there are 3 wires inside the sheath, 1 shield and 2 signal.
Try this version, should address all items I mentioned (including breaking up into smaller moves inside
driver):
Click here for file
Extract to some directory and then navigate to:
C:\Program Files\Common Files\ASCOM\Focuser
Rename GCUSB_nSTEP.exe to GCUSB_nSTEP.bak to back it up
Copy the new extracted file to this same directory
On W7 it will be the 'Program FIles(x86)' folder and you may need to set for 'Run as Administrator' for the EXE
No bother!
