The raster bars and sensors of the printer are quite cheap, and some companies have started commercial use in this area five or six years ago, and the effect is very good. There is already a semi-closed loop 42 motor controller open source solution based on Hall sensors, but after a long search, I have not found a raster bar and sensor open source control solution for the printer. Is there? https://reprap.org/forum/read.php?1,873918,873918#msg-873918 Sat, 10 Oct 2026 19:57:02 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,873918,873918#msg-873918 https://reprap.org/forum/read.php?1,873918,873918#msg-873918 ctma1007 General Thu, 18 Jun 2020 11:44:32 -0400
