Don,

I don't have ready pictures of my machines' cabinets and taking some is a real hassle now. Hopefully someone else could share. If you search the forum though you'd find quite a few. Hood, for instance, posted his photos on several occasions.

Hi Don,

18 gauge should be fine. I think it shouldn't have any issues up to some 10 Amps.

No, Don. I am suggesting you swapping the cables going from the Gecko drives to the motors.

Don,

What happens if you swap the motor cables (running from the Geckos to the motors) of X and Y axes? Does the problem follows or still remains the same on same axes?

Thanks Graham! Nice write up on sub routines.

Hmm... Don't know. The voltage should pull low - effectively 0V. Practically you'd measure something like 0.1V or lower.

I will give it a thought, but hopefully someone will chime in with an idea...

Don't know, Don, sounds like insufficient current. You will see it when you do the measuring. If the voltage drops noticeably when it is connected to the Gecko (probably to 2V or something) then you'll know the current is insufficient.

Ah... then it's easy. Just put an 'If' statement at the top of your M6start macro. Something like this:

If (Input12) Then

'Put your macro here

Else

Message "Tool is stuck in the spindle. Unable to complete tool change"

End If

Now I lost you Peter. You said you had the sensors connected to pin 12 of the PP and you were not getting any signals from them... ?

Don,

It is normal - when starting Mach it takes over the PP and pulls low all the pins. What is not normal is that you don't see the direction pin changing state when moving the axis in different directions. This is strange. You didn't have anything connected to that pin when doing the measuring, did you? I don't know why that would happen...

Where did the D-sub 25 connector go in? How did you plug into the PP DB25? Can you measure the voltage of say the direction pin while it is not connected to the Gecko and compare it to the voltage when it is connected to the Gecko?

Dan
