I just realized that my previous post on this topic is in the Turkish RepRap user group. Woops. The original post is here: [reprap.org] I also posted the question here: [3dprinting.stackexchange.com] The long and the short of it is that uncommenting the JUNCTION_DEVIATION_MM setting doesn't appear to do anything. When I power cycle the controller (SKR 1.3), I have to go through the printer's menus (Configuration > Advanced Settings > Jerk > Junction Dev), and the setting is "0.00" When I start prints with this setting, there is a FULL stop and start of the motors on every angle change. That sucks. When I manually set "Junction Dev" in the printer menu, the problem with motor motion goes away until the controller is rebooted and the setting gets reverted. My Marlin configuration files are on github heer: [github.com] and here: [github.com] Is it possible that this is a bug in the SKR (or maybe the TFT24)? Any help or input about things I can try will be appreciated! https://reprap.org/forum/read.php?13,862036,862036#msg-862036 Thu, 14 May 2026 03:28:29 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,862036,865816#msg-865816 https://reprap.org/forum/read.php?13,862036,865816#msg-865816
There was a bug between the SKR V1.3 controller and Marlin that has been resolved. I'm not sure which commit did the trick since I hadn't merged changes from Marlin's bugfix-2.0.x branch into my local copy for a couple of months.

The answer to my post on Stack Exchange gives a more thorough answer:
