After loading the nozzle remains at 250c. Loading also has extra moves

I’m not really sure the best place to report bugs but this seemed like the best place.

After using the ‘load’ feature, the nozzle remains at 250C. I assume it is supposed to turn the heater off, like it does after the ‘unload’ (which is actually kinda annoying, as you’re generally always going to reload the printer straight away).

Also - when you click load, the nozzle seems to do a wipe… but then it kinda crosses the bed back and forth afterwards for… no reason at all? It almost looks like its going to the filament cutter, but there’s no filament in it at this point so…

Yeah, I agree this is annoying. What I do is just immediately tap the nozzle temp and input the temp for the next filament. I also do the bed while I’m at it to reduce warmup time.

The printer is having a private moment, you shouldn’t be watching … :wink:
I’ve always wondered about this, it does it on the X1C with AMS too. Very odd.

It eventually scrapes off the coating on the back of the plate. Out of print area, but still. Like WHY ???

Its cleaning the nozzle tip from residue that stuck despite the silicone wiping pad.

Ah HA! And here I thought they were just giving it a moment … :grin:

Thx Buddy!

Maybe to scan the QR code of the plate. This makes sense on an X1, but I think they haven’t it coded out for the P1P.

Found that with unloading, if you pull the filament back out manually after unloaded, it will turn off nozzle, but only if you seem to do it almost straight away.

No, that’s not it. The scan for that is the front left corner of the bed. The plate has it’s code on the part you grab to remove it. :slightly_smiling_face:

Then, I think, that move is really unnecessary. ( At first time I was really surprised as the toolhead moved to front and back for loading filament)

Yes, it is necessary, even if it appears a bit odd. As @Thrawn pointed out it’s for fully cleaning the nozzle. I initially missed it’s significance but then realized it’s importance.

The little wipe it gets on the Filament cleaner (that loud back and forth on the Teflon roller in the back left above the poop chute) is not enough to remove very hard stuck on debris on the nozzle. This motion does that.

Everyone loves the beautiful prints we get, well this annoying wait is one reason why. Having a fully clean nozzle tip is critical, not “unnecessary” to get flawless prints.

I fully agree it’s annoying tho’ :grin:

Why does moving to the front of the chamber clean the nozzle? It doesn’t touch anything (that I can see).

I’m not talking about the move it does before printing where it rubs the rear slot on the bed.

I could tell you, but then I’d have to kill you. :astonished: LOL

No bloody Idea. I know it checks the front left edge of the plate to identify the plate, but I know the move you’re talking about and haven’t figured it out.
