Hi! Based on my experience, here are the possible reasons for bed warping issue:
1. Bed temperature needs to be accurate
2. If printing large items (or just long items) infill matters a lot. Less infill or the hexagon/honeycomb infill really really helps with warping. A lot of my warping came from trying to print large items at >60% infill. If you get good layer adhesion, there really should never be a need for such heavy infill.
3. An enclosure of some sort. The piece I put on the top of the printer seemed to have made the biggest difference.
4. Getting a good first layer. Getting your bed leveling right makes a big difference. You want that first layer to push into the bed a bit, but not so much that it distorts your layers. Set the distance between nozzle and bed to about 80% of your first layer height. I use feeler gauges. I heat everything up and let it soak for a bit. Then I place my nozzle directly over each screw and adjust that screw. Then I repeat and repeat until it stops changing. Then I confirm by moving the nozzle to the center and if adjustment is needed, I adjust all four screws by about the same amount. Then one more pass over the screws.
Let me know if this will work for you. Hope this helps!
Please explain to me how to...
