Got some infoormations for you, additional to Gregs wisdoms (experienced #2 waaaays to often btw.) I made some changes that got rid of all banding issues, that you can remove - so currentlly only having the "benchy hull line" apparent: 1. tightened the Bed leveling screws: a 400mm Bed on three m4 screws was not the smartest thing to do but still workking IF the springs are really compressed. 2. PID-tuned the Bed: Large AND thick aluminum bed with springsteel on top makes thermal expansion an issue and as the standard in Marlin is Bang-Bang, it really moves quite a bit 3. my X carrier rail sled was extra loose, meaning a possible wobble of <1mm hope these points might help others

Same here...basically commenting as a "metoo" thing and to keep this thread alive I hadthe issues with my HEVO, HEVO-RS and my BLV Cube (one printer, modified in hope of getting rid of this s**t) Images are from tst pieces placed in all four coners of the bed to maybe pin it to one part of the printer but nope
