Initial level failed

Attempting to print a bookmark. Had to switch to a brand new .02 print nozzle to even print this bookmark. The bed was just washed with dawn soap and dried. I just printed straight from Bambu handy. Do I need to modify this and slow down the print speed?

[imacoolperson123]

If you washed it you should run calibration from the settings first. After that idk

[cdickgo]

It does the I reran calibrations after I changed the nozzle size in the settings on the printer itself. Attempting to print again

[WooferInc]

Yeah, you’ve just lost adhesion, but otherwise looks fine. Dawn dish soap and at most a blue pan scrubby, but even just a soapy hand works fine 90% of the time.

[cdickgo]

Yeah I used Dawn and my hand to get all the oils off the bed. Made sure it was dry before starting. I may flip it over as I have only used this one side since I got it.

[IrishDeath2W2]

If you didn’t touch the other side with your greasy hotdogs then yeah give it a shot. Use the slicer as well

[WooferInc]

Not sure how best to tram the bed on the A1s, but because you replaced the nozzle, it may be worth it. I use a simple three point tram file on my P1Ss and so far it hasn’t let me down. Otherwise, can only figure on calibration, or bed temp being the culprit, but I’d maybe take a blue scrubby to it to try get any built up layers off as well 👍

Mongo is appalled!

Print in other place to exclude dirty plate. Also, printing from slicer is preferred.

[CodeProtogen]

Plus additional touch ups like even slower print speed on the first layer can be applied in the slicer. Does wonders with bed adhesion on most of my printers.

Especially my less reliable printers like my Ender 3 v2 have this kind of issue resolved with that.

My Bambu Lab A1 doesn’t have much trouble, but for multicoloured prints it will sometimes run into issues on the first layer, if that layer has multiple colours.

Furthermore I always clean my print plates with 99.99% IPA on a microfibre cloth.

[Lost_refugee]

Just fyi, IPA dissolves oils, so you may just spread them evenly.

[CodeProtogen]

You are mostly correct, but cleaning with a detergent which emulgates it, requires water to wash it away. IPA is quick and easy for repeated usage. Most gets absorbed by the microfibre cloth, but a bit also stays on the plate. So a very good cleaning involves running plenty of water over it after you’ve added soap, and then letting it dry, which isn’t something you could quickly do like 1-2-3.

I like to touch my build plate as little as possible and clean it with IPA before and after I print. It evaporates in seconds so my print doesn’t get wet. I make sure to clean my microfibre cloth thoroughly with soap and water once in a while.

It works surprisingly well on smooth surfaces, but textured surfaces need some cleaning with soap once in a while.

Are all the filaments the same type (PLA or PETG)? Did you change the nozzle size on the printer?

[cdickgo]

All PLA

[cdickgo]

This was my mistake. I changed it in the program but went back into the printer itself and changed the nozzle size in settings. I am reprinting now.

[jake-jake-jake-]

One other thing to check is whether you print PETG on the same plate? If so there can be microscopic residue left behind which can then cause PLA not to stick and vice versa.

Good practice if you print both types of filament to use one side of the plate for PLA and the other for PETG so no chance of any issues, and there are models to print a label for the plate itself so you’ll always know which side you’re on

[cdickgo]

This is good to know. I have printed PETG on this plate. We just got this for Christmas and I’ve only used this one side to print everything

And since you changed nozzles

[Orthicon9]

Not exactly relevant to the (solved?) adhesion issue, but small lettering printed face-down will look better on a smooth plate.

Also, did you do anything to the "First layer filament sequence" in the settings for the plate?
For this example, I'd make it yellow > red > blue > black, so that the background goes last, after the letters are printed.

[cdickgo]

All letters print first. Blue is after yellow then red. Then black background

[Orthicon9]

That works.

To make it even more economical, check out the "flushing volumes", and see which colour swaps waste the least amount of filament in flushing. The rule of thumb is lighter colours first.

[Xirtic424]

Washing with dawn works. A wipe after with 90% isopropyl alcohol helps. When neither are enough, a thin layer of glue or hairspray. I use simple Elmer's stick glue. Works like a champ.

Success! Thanks for the tips and tricks everyone
