Error when starting up Two Trees Sapphire Plus for the first time

[rongee]

Hi, I've been talking with the folks at two trees, and after some diagnosing, they've decided to sent me a new "thermal". Now, I don't know if that means they're sending me a new extruder and cable, or just the thermistor or what. And, yes, apparently, the Err2 is indicating there might be break in one of the wires that goes to "Extruder head 1 thermal" on the motherboard. Yeah, I found that error message as well after a bit of a treasure hunt.

Ah, so I need to feed the filament through the dual drive extruder and through the longer tube all the way into the extruder. I get blocked after pushing a bit into the dual drive extruder, so I hoped maybe that meant the filament tool would activate the motor on it and push it the rest of the way. I get I need to loosen up something in the dual head extruder.

On leveling...my printer came with 2 z-axis limit switches as well as a "3D Touch" unit and cable. The cable not only had the wrong connectors but it wasn't long enough, so I just ended up making my own cable. Then I found out that the 3D Touch uses the same motherboard plug slot as the z-axis limit switches, so you can only have one or the other. So, right now, I put the 3D Touch aside and am just using the z-axis limit switches. Haven't tried leveling the bed yet.

Browsing around the menu, I also found that the movement buttons don't work, but I chalked that up to the effects of the Err2 message. There's also a chance that those buttons are actually making micro movements, and I just can't see them. But I'm pretty sure they're just not doing anything at this point.

Thanks for the info. Much appreciated. I'll post more as I find out more.

I haven't bothered using the using the BLtouch either. I just homed and manually leveled the bed using a piece a paper for now. But as aardvark mentions, the Bltouch should definitely be able to be wired up without having to disconnect the Z limit switches.

As for the Err2, mine has now reliably gone away after noticing the connection for the wire going into the Hot 1 Interface on the motherboard wasn't tightened very well. Tightening it solved my issue. And yes, after Err2 is gone, the movement tool and all the menu options now work properly.

I think I'm all setup for my first test print, but unfortunately my computer doesn't have a micro SD card slot. Waiting on an external one to arrive so I can begin testing.

Hmm, I'll go back and recheck those connections. The cable to the extruder was already connected when I got the printer, so I hadn't paid much attention to that.

Isn't there a slot on the side of the printer where you can plug in the SD card? Just to the left of the USB plug on the right side of the printer?
