Been messing around with the Z offsetup when doing lots of test prints. So maybe it's so far out now.

I think I need to take a drink and start the setup from scratch again.

From my experience, when looking at how the filament is sticking to the nozzle I would say it is too far from the bed...

Best calibration tool I have found is this: https://teachingtechyt.github.io/calibration.html#firstlayer

Trying to print benchy the outline seems somewhat ok but then it moves to the middle and nozzle gets clogged up

Definitely too far, you can see the gap between lines, they should be touching each other...

 

[Werfetter]

Yup too far.

You mention having a BL Touch? Did you upgrade the firmware after installing the BL Touch? I installed from here: https://github.com/MarlinFirmware/Marlin/tree/bugfix-2.0.x/config

I assume it would be similar if not the same as my 5 Pro. Run the Z-probe offset wizard making sure that by the end the nozzles clutches at the paper, just like with normal bed levelling.

Then make sure to save your settings. I missed this step the first time, so after starting the next print or switching the machine off and on, the new Z-offset position would be gone, and the prints would not adhere.

Anyone here used mambawire?

The first role of filament I ever printed with. It was fine but I prefer cctree or funkiments. The prints just look better.

Courier dropped these off today....SBS filament, locally made by Fill-X. Bought through DaVinci Lab (very good service by the way!).

Some interesting points for me on this filament:

• Non-hydroscopic - so doesn't absorb moisture like PLA (no more dry boxes )
• Food safe - opens up a lot of printing options
• Can be smoothed using d-limonene (apparently for much the same result as ABS and acetone)
• No odour when printing
• Supposed to print at about the same temps and settings as PLA (I am currently going at 205C extruder and 60C bed - left all of my other settings as is from my PLA+).
• Longer/more filament on a roll. I noted now when loading it on the printer that the filament does feel much softer and lighter than the eSun PLA+ I've been using, so there should be more volume for 1kg. Will see how this translates into printing and the strength of the print.

Very interested in seeing how it prints. Busy printing a small vase now in 'vase mode' using the bronze filament.

Well took your guys advice and levelled the bed a bit closer and used some hairspray and got benchy to 80%. As I was watching it came loose and messed up the print. Disappointing but at least I’m getting there.



Any idea why it came loose after almost being finished?

Bed Temp?
Nozzle Temp?
Filament?

All these things affect the adhesion of your print...

Also ensure you spray the hairspray on when the glass is cold and then heat it up, works best that way.

Went with the default PLA settings on the printer, 200C nozzle and 60C bed. Should I increase the bed temp?

Do you have hugely fluctuating temps in that room? Like a door that's opening to the outside and letting a lot of cold air in? PLA shouldn't really suffer from those kinds of fluctuations tho.

What Filament brand and type is it?

I'd recommend going slightly hotter, especially on the first layer. Try first layer at 215 and subsequent layers at 210

I mostly print with PLA+ from eSun and the range is 205-225 with a bed of 60-80


I won't go higher on the bed as 60 should be perfectly fine.

Anyone want to try this?

You can also try glue stick "prit". Its the only thing I use as its easy to clean with just water and works with most filaments. Hair spray tends to build up on things from over spray over time so not a fan. But ultimately getting good adhesion comes down to correct spacing of the nozzle and takes a bit of time to get your eye in as to what works. Also set your slicer to use the same first layer hight for all print hights. (0,2 works for me can even go 0,3 if your bed is not very flat)
PLA can be printed on a cold surface and 60c is fine so don't worry about that too much.

This is sort of what you're after for a first layer
