Just a quick finding. Sometimes the Terminal window goes into "Minimize Limbo" and cannot be brought to the front when using the minimize button. In the past, it would go to the dock and you could bring it back up easily. Even shutting down MC and restarting, terminal would startup but be lost in the background. I could see it running in mission control but clicking would bring back the main GUI for MC.

A temp fix if others encounter this. Go to System, Displays, and resize your display. Pick a resolution that forces the terminal window to come back back to the front.

What may be happening, is when either moved out of the way, (I.E. to the bottom or off screen), or minimized, it somehow goes past the native screen display setting and gets locked there. Older revisions of MC used to send the terminal to the dock as a separate icon, but it looks like terminal is now hiding behind the main MC icon on the dock.

Spoke with dev. and apparently they plan to move it within the main MC app.

Hope it helps

Got it sorted Unlimitedbacon!!!

Think it was an issue of me using T and T1 (instead of T0 and T1) Second issue seemed to be that it needs to be linked to an extruder. If not, both hotend mosfets will turn on together.

Here is a copy of the Extruder and Hotend section of the config.txt only for those that have the same issue.

Here is a link if allowed (http://pastebin.com/rib12XYD) of the full config.txt i stumbled upon.

All mosfets now switch on respectfully and all temps are showing correctly. Hope this can help others with the SBase that are trying to setup dual hotends.

Thanks unlimitedbacon for the help.

Yes sent M105 and get back all responses in mattercontrol...really strange.

Been messing around with it last night, Not sure if it might be the SD card or config in some fashion. Another problem cropped up in conjunction while investigating. The mosfets that turn on the heaters for the hotends (specifically 2.6 and 2.7) seem to turn on together even though they are mapped seperately.

Working on a mac with TextEdit might be messing up the format as I seemed to had an issue with setting arm_solution to corexy when doing the initial setup. For some reason it rejected reading that line and kept loading as a cartesian. So the next step I can go about is using the config from my Delta Sbase I have to see if the board I am working on is the issue. Then will focus on the hotends to rule out a SD, config.txt or board issue.

Will post a log tomorrow if I cant work it out. If I hopefully figure it out, will post my detailed findings in case someone else happens to run into the same issue.

Hi all,

Working with a smoothie (MKS Sbase)

Looking to get into dual hotends.

Kinda trying to figure out an issue with my second hotend thermistor not showing up in the GUI (shows 0 contstantly) I did swap out the connections to check for operation, and all good. I also ran pronterface to rule out a damaged board, and all three temps (heatbed, hotend1, and hotend) show up. The heatbed, along with the thermistor for 1st hotend is all good in Mattercontrol, Just the second hotend not reporting in the GUI.

Many thanks is anyone can help
