Thanks, I will give both of these a try. 215 degrees C is the PrusaControl settings.

Do remember that there is such a thing as "High temp PLA" that needs to be printed at 215 or above. Normally the packaging or on the website it will tell you the needed print temp. So it could also be the right temp.

@Granny that is very well possible, thanks for the addition.

<p>My low-tech solution is to smear on some school/craft glue-stick. This is so quick and so easy yet it has saved me so many times from going any further troubleshooting adhesion problems.</p>

@AndrewP, did you give it a go yet? I know it sounds almost too easy, but it works brilliantly.

<p>I am trying to print a model that has (at the start of the print) several small parts attached to the bed. Some of these parts have bed contact 2.5mm x 20mm.</p>

<p>After a few layers, if there are any imperfections in the previous layer, the hotend is bumping the imperfection and knocking the part loose.</p>

<p>I am using a genuine Prusa i3 Mk2s with Filaform PLA. I am slicing with PrusaControl and using the "Generic PLA" settings, which is giving me 215/210 degree hot end (first/other layers), and 55 degree bed. I have the fan enabled. The print bed is clean and dust free</p>

<p>How can I improve bed adhesion for these small parts, ideally without adding brims etc? </p>

<p>Thanks</p>

I also found out that using wet screen wipes to remove any residue from touching works really well for increasing bed adhesion.

Small part bed adhesion

# Small part bed adhesion

(Asked by: username_0 on 2017-10-18)

I am trying to print a model that has (at the start of the print) several small parts attached to the bed. Some of these parts have bed contact 2.5mm x 20mm.

After a few layers, if there are any imperfections in the previous layer, the hotend is bumping the imperfection and knocking the part loose.

I am using a genuine Prusa i3 Mk2s with Filaform PLA. I am slicing with PrusaControl and using the "Generic PLA" settings, which is giving me 215/210 degree hot end (first/other layers), and 55 degree bed. I have the fan enabled. The print bed is clean and dust free

How can I improve bed adhesion for these small parts, ideally without adding brims etc?

Thanks
