Hello, I am using Simplify3D with the stock R2 profile which was working great for awhile. All of a sudden however, I am getting these dimples in many layers and I can't figure out where they are coming from. - The blue example is with the stock 1.5 retraction distance and the grey one is with this increased to 4mm retraction which didn't help and might have been worse. - This occurred both before and after the move to the RoboOS 2.0 software. - This is after a service visit where the whole hot end and circuit board for the extruder was replaced. Any thoughts, anyone seen this? I didn't see anything on this page: https://www.simplify3d.com/support/print-quality-troubleshooting/#print-not-sticking-to-the-bed and it doesn't seem like simply increasing the retraction did anything and if anything made it worse. Thanks!
