How am I doing? Day ???

I started these Havana 608 seeds inside in late march/early April. Transplanted outside near the end of may. Everyone seems real happy except the middle guy who I suspect is being robbed of sunlight.

In Utah, zone 7b and I’ve never grown tobacco before. Starting to research harvesting and curing so if anyone has some good resources I’d love to read them!

Hotend Issues - Update w Pictures

I posted a few days ago, but have photos now and a bit more info.

I have an Ender S1 Plus running Klipper. I print mostly in PETG and hadn't had any major print failures until recently, when an overnight print went wrong and I woke up to a huge block of hardened filament around the hot end. I painstakingly cleaned it out, but the thermistor wires were destroyed in the process, and I was lucky to even get the bolt heads clear enough to remove the hot end.

I figured this was a good excuse to "upgrade" to the high-temp all/bi-metal hot end from the S1 Pro, so I bought this one on Amazon which — funny enough — looks identical to my old one aside from the steel nozzle. Perhaps the previous owner had already upgraded it? I ran PID calibration in Klipper and set my printer.cfg for a higher (300°C) temp.

Right off the bat, I had a hard time feeding filament all the way through to the hot end, At first I couldnt get it past the gears of the extruder, but after a few treis and some iwggling I got it past them only to get stuck right at the top of the copper throat of the new hot end. I took the whole thing apart to look for a blockage, but nothing was in there. I fed filament through the extruder, heat sink, and hot end (nozzle off) individually while disassembled - confirming each part was unobstructed. I put it back together with the filament still fed through and I got one successful print. But the next one failed, "printing" but extruding less and less with each layer until nothing extruded at all - the extruder wheel was skipping the whole time. I adjusted the tension bolt, but even fully tight it wouldn't push filament.

Taking it apart again, I noticed the PTFE tube I've seen in tear-down videos was missing (the one on the "cold-side" that runs through the extruder to the heat sink). My theory is the filament is exiting the drive gears into an unsupported gap, missing the throat bore, and buckling. and without the tube inside, the gears aren't grasping the filament properly.

So my question: DO you think I am on the right track, and any idea the length of PTFE that was supposed to run through the extruder? Pretty sure it was 4mm OD, 2mm ID tubing from my research, but I would love to know the length spec.

Any advice appreciated.

Hotend Issues

I have an Eder S1 Plus. It's my first printer, I bought it used and installed Klipper on it. I've tinkered and learned a lot in the 4 months or so of owning it. I print mostly in PETG and hadn't had any major print failures until recently. I had an overnight print go wrong and woke up to a huge block of filament hardened around the hotend. After painstakingly trying to clean it, I basically gave up. The thermistor wires got destroyed in the process and I was lucky just to get the bolt heads clear enough to remove the hotend.

I figured this was a good excuse to "upgrade" to the high-temp hotend from the S1 Pro, so I bought one on Amazon, and I haven't been able to print since. Right off the bat I couldn't feed filament all the way through, so I took the whole extruder apart to look for a blockage. Nothing. I then took the heatbreak and hotend off and fed filament through the extruder, heatbreak, and then hotend (nozzle off) individually, and put it all back together (which sucked, but proved the path was unobstructed). I was able to print something after that without issue, but the next print failed and the extruder wheel was skipping the whole time.

I took it apart again and noticed the PTFE tube that I see/hear mentioned in teardown videos was missing. I'm thinking I probably misplaced it when I took the extruder apart the first time. I cleaned everything up and tried again. Still can't get filament to feed all the way through, and I'm getting zero extrusion when I try to see if the machine will just pull the filament through itself (tried M83, G1 E100 F60 with it heated to printing temp).

Now I'm wondering if A) the hotend I got isn't actually compatible with the Plus. It looks exactly the same as the old one, save for the steel nozzle. B) the missing PTFE tubing is causing the issue, or C) a combo of both. Does anyone have any advice for me? Also, is it possible I already had the "full metal" hotend? The standard version seems to have a silver (steel?) throat, whereas both my old and replacement one have a copper throat.
TIA!
