First Layer Bubbles problem what you think?
Hi man!
I have this problem sometimes with my first layer and abs..... have u ever seen it?
Re: First Layer Bubbles problem what you think?
That looks like your nozzle is just a hair too close to the bed. I would try using Live Z and decreasing that number slowly in increments of .025 until it still has coverage but less of the random strings of filament. Personally, I'm ok with some globbing like that since as other layers are printed, you won't even notice it. Or at least I don't notice it once its all done.

Tnx for reply! It's work 😀 Less bubble but it's ok! 😀 Now i try z-abs Have you ever used it?
p.s every time i move printer from a different place Z loose or gain 0.3 0.4 😕 If u use y frame like a handle
Re: First Layer Bubbles problem what you think?
ABS you will normally need to lower your Live-Z by another .150 or more to start. I switch between two often. I stopped using Live-Z for the switch and added the switch to the gcode through Slicer. You can add an offset in slicer printer settings and give the printer settings there own name. I just used the default printer settings, added the offset from what was shown on my Live-Z and then saved them with the PLA or ABS in front of the original printer settings name. After that, I set my Live-Z to 0.00. You can still use live-z if its not close enough to the bed, but if its still too close, you would then need to change the Z offset in the printer settings to make the change.

Why are you moving your printer? Try to find a spot and leave it there. It is recommended to a full calibration every time it gets moved for that same reason.
Maybe you are going to shows all the time and I understand if that's the case but really just leave the printer in one spot.
Re: First Layer Bubbles problem what you think?
Agreed, unless it needs to be moved, best to keep from moving it.
If you have to move it around, then I would check all your nuts and ensure they aren't loosening up. I have had to move my printer on rare occasions, but never had a problem with it going out of alignment.
Also, if you have to move it/travel with it. Look up some printable parts that you can lock the XYZ axis's in place for the move. Prusa makes them for when they ship built printers, but haven't seen the files to print them.

Hi all 😀 I need to move From My room to outside..... i have a little terrace it's useful when i print ABS ...i'm still using HEPA Filter....

The shipping clips that come with assembled printers can be found in this thread - https://shop.prusa3d.com/forum/original-prusa-i3-mk2-f23/where-is-the-y-motor-stabilizer-stl--t2017.html - along with a couple of other bits.
Re: First Layer Bubbles problem what you think?
I put a black garbage bag over my printer when printing abs to maintain the heat. But I have never noticed the smell unless I stick my nose in there while is printing. Once it cools and I remove the bag there is no smell
