I didn't, DC42. That must be it. Thanks much (and enjoy your holiday)!

Thanks for the info, Snowcrash!

Enjoy the Vacation!

Quick question for those of you in the know. I bought an expansion board for my WiFi to add additional extruders and just hooked it up w/ the supplied ribbon cable. When I turn on the machine, I get an error stating the additional drives on the expansion board are "shorted" and in "over temperature." Is this normal? Will I get this error until I actually hook-up extruders or is there something wrong?

Thanks in advance!

Mystery (Apparently) Solved.

First a big thank you, as always, to DC42 for such great support!

I believe the problem was with a Windows 10 update. This morning, I noticed that the machine had recently updated so I uninstalled/reinstalled the update. Everything is now working fine. Just one of those things we (or I) don't normally check. So, lesson learned.

Impressive!

Some additional information:

I just remembered that for the past few days, my Duet WiFi has been randomly disconnecting several times during various printing sessions. The print continued, but the connection was lost several times and I had to manually reconnect. Bad WiFi module?

Here's hoping for a simple fix. When I tried to start my Duet WiFi printer today, the computer couldn't find the http I use for my printer. When I plugged my Duet into the computer via USB and started YAT to see if I just needed to turn on WiFi again, I got the following message for the com port on which I have the Duet:

**Terminal Error

Unable to start terminal!

System error message (System.UnauthorizedAccessException):
Access to the port 'COM6' is denied.

YAT Hints:
Make sure the selected serial COM port is available and not already in use. Also, check the communication settings and keep in mind that hardware and driver may limit the allowed settings.**

I get the same error message regardless of which COM port I use. I'm assuming it's a problem with the WiFi module. Any help would be appreciated!

Thanks in advance,
Tony

I had a similar issue and it turned-out one of the Z-motors was going bad. Just a thought...

All axes homed and on to tuning. THANK YOU ALL!
