[Geschlossen] slight warping (from the bed)  

RE: slight warping (from the bed)

You'll have to give us more information:

• Filament used?
• Print settings? (temps, brim, etc.)
• Bed cleaning (or other preparation) procedure?
• Part geometry? (preferably with pictures of the warped part?
• Environmental conditions? (Room temp, air drafts etc.)

Your question as it is can just be answered by stating the obvious: Parts can warp, certain measures can prevent warping. But I guess that is not of much help...

RE: slight warping (from the bed)

PLA from prusa

215/60 on bed

i use 91% iso to clean

warped part wase the base of the millennium falcon (the 2 halfs that get glued together, so rather large section of flat PLA

75-76 in the house with the AC on (I am in FL)

Thats the best I can do for now, I do NOT have an enclosure onthe printer yet..

RE: slight warping (from the bed)

Try different cleaning of the bed. Many people here would recommend water with dishwasher. Or try using an adhesive like gluestick or hairspray (i use 3DLac).

Try using a brim

• A dirty PEI print surface. Even if you don't think this is the cause, it's always a good idea to make sure your PEI surface is clean before trying any other fixes. If it's a smooth PEI sheet, take it to the kitchen sink and give it a good dunk with Dawn (original formula, no vinegar or hand softener variants) dishwashing soap or your local equivalent (e.g. Fairy in UK). Use a clean paper towel to clean it off, and another to dry it. Avoid using any sponge or cloth that has been in contact with grease. Above all else, avoid touching the PEI print surface. Once it's good and clean, you should be able to use 91%+ isopropyl alcohol between prints, 100% acetone when that fails , and another dunk when acetone fails. Worst-case, use a 3M 7445 ScotchBrite pad or equivalent on smooth PEI to give it a very light buff, but only infrequently. If you've got a textured powder-coated PEI print surface, the official instructions are to use 91%+ isopropyl alcohol on it only. Rumors persist that some tribes deep in the jungle have had good luck getting started with these sheets by giving them a wipe with 100% acetone and a dunk with Dawn. Either way, there's no real warranty on these sheets. YMMV.
• If you have not already done so, try using Jeff Jordan's "Life Adjust" procedure for calibrating your Live-Z setting. It is much easier to use and understand than the on-board routine. It's much easier to make mid-print adjustments accurately with. In general, start high (less negative) and work lower (more negative) in large increments (e.g. 0.1mm) until the filament starts to stick on its own. When you've got your Live-Z setting adjusted properly, you should be able to gently rub the extruded lines on the PEI surface without dislodging them.  Then start lowering (more negative) the level until there are no gaps between layers.
