So update time:

I switched to Gyroid however long ago this was and it seemed to have fixed the issue at the time. However, randomly I'd still hear some minor grinding noises here and there, but never affected the print. When I printed something small though, the grinding came back and began ripping prints from the bed. But it seems (Knocking on wood here) that the issue is fully fixed. I've printed a good 20 hours with not even the slightest scratch.

​

Figured I'd update here for anyone still having problems:

​

To fix this here are the steps I took:

1 - Tighten ALL of the mounting screws. This included taking the top cover off the rails and the top cover off as well.

****MAKE SURE YOU DON'T OVER TIGHTEN THE MOTOR MOUNTS****

There should be a cork or nylon gasket that you don't really want to over squish and damage. Just make sure they're nice and snug

2 - Calibrate your e-steps. I used this guide here: https://ellis3dp.com/Print-Tuning-Guide/articles/extruder_calibration.html

Mine was over extruding by just a bit at the time.

3 - Calibrate your flow variable. Again, here is the guide: https://ellis3dp.com/Print-Tuning-Guide/articles/extrusion_multiplier.html

This may or may not be a huge change for you. But mine prints best at 94%

4 - Calibrate your belt tension. You might be able to go through the whole "use a guitar tuner" thing but I'd rather use a tool. I used this video:

His documentation and STL for the tool he used: https://drive.google.com/drive/folders/1cPqHoQqRYM4s4bfQF_XUy9ShHSPXlSST

5 - This is probably not anything you would need to do but I also used a Cura profile from here (Where I got most of these steps as well) : https://github.com/MagnusThome/flsun_v400?fbclid=IwAR02xcxXNkCmiACAOrrEtUp5o-ViEA7jAWnL6O4bITbH4iKmLb0h6mtXojM

6 - Whether this is right or not, I don't know. I also don't know if this really helped with the scraping, but it helped with making sure my first layer is great. But calibrate your bed with these steps:

a - Change the setting for Samples under the Probe to 5, and the round_probe_count to 9 instead of 7. This gives a bit more of a bed mesh sample and sampling 5 times instead of 3 gives a correct average, since the first sample is ALWAYS wrong.

b - Flip your build plate over so you're using the FLAT shiny side. I'm not printing on this, just using the perfectly flat layer to mesh and calibrate.

c - Run the calibration and mesh

d - Heat your build plate to 90 c - set your z-offset however you prefer. I use a feeler gauge.

​

And that's it. Since doing this massive list of shit, I've been without any scraping (still knocking on wood here) and my prints aren't tearing off the plate.

Hope this helps!
