Review on 🖨️ Comgrow 3D Printer Filament 1.75mm Spool: Additive Manufacturing Supplies in 3D Printing by Boss Spangler

I have Ender 3 v2 for 3 days. Before that I had no experience in 3D printing. I followed the tedious manual alignment instructions on YouTube and was able to print the dog and cat patterns that came with the printer using the white spiral filament that came with the printer. Then I switched to this black thread and had problems. The first line on the left side of the bed didn't hold either. As he drew the outline I saw the thread stick a little and then he started rubbing the bed as the head moved. Or the first contour is lowered but irregularly shaped, and the second line brings everything up. I tried higher temps (230/70) and managed to get things to stick to the rock, but then warped and twisted when done, or when it was high it detached from the board. I updated my printer firmware on JyersUI (on YouTube) and used the leveling feature to walk around and level the bed. I also made sure to heat the blade and bed while leveling. I used paper and adjusted it to pull the paper heavily (not tear) between the bed and the nozzle. I probably went through 5 or 6 times until they all got pretty repetitive. Adjusting one spring seemed to throw out the other, so it took a long time to fix. I also started using a raft. Suddenly it started working. I lowered the temperature to 200/70 and 0.15 layers and repeatedly got successful prints. I'm not thrilled with how the bottom looks on the raft, but as long as everything works I won't complain (much). I don't know enough to compare this thread to others, but I don't feel ripped off anymore. I think every "level the bed" advice was true, even if you think you've leveled the bed.
