Hi all, We are using 'Marlin-2.1.1' with BTT Octopus Pro board and BTT TFT 5.0. 500x500 machine with Dual extruder. Both nozzles are having an offset of 66mm. PID value is given separately for both hotends. When heating T0 (Left), only T0 is heating. But when heating T1, both T1 (RIght) and T0 (Left) also get heated. It is physically heating. Any help is much appreciated. Thanks in advance. https://reprap.org/forum/read.php?415,891095,891095#msg-891095 Sat, 10 Oct 2026 20:17:52 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?415,891095,891104#msg-891104 https://reprap.org/forum/read.php?415,891095,891104#msg-891104
We checked with Pronterface. At that time the issue didn't happen.

Someone has already raised it in Marlin and it seems they have updated by Jan-22 itself.

May be the issue with BTT TFT?]]> selva_tvi Firmware - Marlin Tue, 22 Nov 2022 00:44:54 -0500 https://reprap.org/forum/read.php?415,891095,891100#msg-891100 https://reprap.org/forum/read.php?415,891095,891100#msg-891100
Use a control program such as Pronterface

use gcode to set the temperature eg M104 T1 S205

Check what is happening.]]> Dust Firmware - Marlin Mon, 21 Nov 2022 16:54:38 -0500 https://reprap.org/forum/read.php?415,891095,891095#msg-891095 https://reprap.org/forum/read.php?415,891095,891095#msg-891095
