Review on Befenybay 10PCS 10Mm OD 25Mm Long Yellow Light Load Compression Mould Die Spring (Yellow-10-25) by Wayne Drakh

These springs appear to be good quality at first glance, but they are VERY stiff for manual bed leveling or projects that require a larger compression range. To level the bed, it is usually necessary to compress the springs as much as possible, set the Z axis to its original position, then go to each corner of the bed and loosen the springs so that they almost touch the nozzle . This means that with a higher compression range (i.e. lower coil resistance) you can fine-tune your settings. They practically do not compress. In the photo, I try as hard as I can with my index finger and thumb, and they barely flex 3mm. If you try to level your bed with it, you will create unnecessary mechanical stress on the bed and likely warp your slab. The thickness of the spring is 1mm and the height of the coil winding is 1.2mm. There are about 11 turns in a spiral coil, which is pretty tight. I had a different design of the clamping mechanism that required springs of this size, which is what I originally ordered them for, but now I have to deal with the return and search. spring with less resistance. It's my fault as a buyer in this case, but I also feel that the sellers should have included these qualities somewhere on their list. A little annoying.
