@dc42 Thanks again .. machine is back and functioning well .. may even have solved titan extruder problem .. woo hoo..

If I have read correctly, no extra flyback diode is required on Fan 0 (already protected by board) for a part cooling fan ? It is a 12v brushless that cab take 230 or so mA.

Yup ,, Its a 2 .. TMC2660 Chips .. and I see Duet v1.02 on the Board..

Thanks

Hi,
Beginning to think that I have a Duet 2 not 0.85.. I have 5 fan pins like the 2 docs instead of four like the 0.85.. I tried to login to the old account but no luck with login or changing password.. I purchased on Aug 2, 2017.. Do I have a Duet 2?
Regards

What size difference between the boards ?
Are the dimensions listed somewhere?
Thanks and Regards

Hi.. Thanks.. Thought that would be the case.. I am running it off a 12V power supply so a 12V-2 wire print fan it is..
Thanks

Just double checking what I need here, a 2-wire 12V print fan for the Fan 0 (PWM) connector or am I reading the wire diagram wrong? I have 4 2-wire print connectors but it also has three jumpers below then again, it appears to be jumpered as VIn (12V).
Am I reading this all correct.. I wasn't expecting the jumpers or are they for something else?
Regards
