Every day is a learning day 😊 Well done for figuring it out. Look for tree supports as they can be a lot more useful at times.

Thing with Benchy however is that is should be printed without support as a test for the printer.

You can now print the add-ons like smoke and make yours even more special 👍

Hi Ed

You certainly are having a fun start to 3D printing. Can I suggest that the smell you are getting isn't from the new filament but the old filament that I think is still clogging your nozzle. The increase in temp you did is likely to be burning the clog. I did suggest to you before that the breaking filament was caused by the remains of your original clog in the nozzle. 210C is to be honest a bit high for standard PLA. There are plenty of guides online showing you the best way to remove/clean your nozzle & hotend.

With regard to your bed levelling where you used a sheet of paper & got better prints - paper is an insulator & also burns... if needing to use a spacer under the bed, please use aluminium foil. This will not only not burn but will allow better heat transfer to your bed, which could save you having to bump the bed temp like you did. 😊

Cleaning the bed is really important too - I use IPA but a good clean with soapy water does work too. That might improve your adhesion.

Hope this helps a bit & don't get sucked into the hole where people tell you to change everything on your printer.. the Ender 3 is a good solid printer out of the box. Constant learning will come with being an owner 😁

Aren't 3D printers fun...

As you have had a clog & cleared it with the wire tool, the chances are that your breaking filament is caused by... a clog. The tool only opens a small hole but the actual nozzle/hotend is likely to be full of filament and restricting the flow. As you didn't have the bowden tube locked in place(blue clip) it is likely that hot filament oozed out between the end of the tube & the nozzle. This will take a bit of patience to clear out.
As a starter, I would do what is termed a "cold pull". Turn on the printer & select the pre-heat printhead for PLA (I assume you know where that is if you have levelled the bed), while it is warming up, remove the blue clip & unscrew the bowden connector. Once up to temp, pull the filament sharply out of the printhead. With luck you will not break it and will pull out a nasty lump of plastic on the end of the filament. Cut this off. If this worked then re-insert the connector, push the bowden tube right in, pull the wee bit up and put on the blue clip. Hopefully that works or you could be looking at taking the nozzle off for cleaning (done warm too).
I also advise getting yourself a new SD card as the one supplied is junk and will cause issues with your prints.

Are there any members going too the Ship Show in Edinburgh on 11th June 2017 ? it is a Sunday and I fancy going if we have nothing else on that day, is there anyone else interested in going ?
