I have a ton of good cards from my go pro laying around that I switched too and that fixed it. I also decided to print on rafts only as they stick very well for me vs using glue. I have great first layer squish just a lot of my prints seem to be y?all for how lil bed they touch. I do like having the sensor just because I don?t want to scrub a print because I wasn?t there the second it ran out and it just kept going. Do they offer 1.75mm filiment in larger than 1 kilo rolls? I haven?t seen them just 1 and .5 k
