I have already submitted a ticket on this, but wanted to know if anyone out there has experienced this before. It doesn't matter if the print file is sliced directly in Flux Studio, or in Simplify3D and brought in as gcode. The first layer prints just fine, and when the second layer starts, the printer slows down to a crawl, stutters, starts and stops, stutters, etc. Then, about halfway through the second layer, the printer picks back up again and behaves normally on the remainder of the print. It's just happening on the second layer. I've tried to run different files and get the same behavior. Again, it doesn't seem dependent on the slicer, and it's always the second layer. Strange, huh? Any ideas? I've run this on both my Mac and my Windows 10 pc, I've removed and reinstalled FS, I've rebooted the printer and reinstalled the printer and toolhead firmwares. No joy. Still behaves the same. BTW I'm running FS 0.4.2 and the latest firmwares. Went back to 0.4.1 which was working fine for me and still got this behavior.
