Hi there, I've followed the instructable to add a heat bed to the Type A Machines 2014 but I cant get the heat bed to work. According to this diagram the heat bed goes in "HB Out" and that is what I did. After changing the setting in Marlin I can get the thermistor to work and display the temperature but so far no success with the heat bed. My only chnge in Marlin's configuration is: #define TEMP_SENSOR_BED 11 Am I missing something in Marlin? Thank you for any help you could provide https://reprap.org/forum/read.php?1,686742,686742#msg-686742 Fri, 14 Aug 2026 05:01:05 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,686742,686854#msg-686854 https://reprap.org/forum/read.php?1,686742,686854#msg-686854 ggherbaz General Thu, 14 Jul 2016 19:14:03 -0400 https://reprap.org/forum/read.php?1,686742,686742#msg-686742 https://reprap.org/forum/read.php?1,686742,686742#msg-686742 I've followed the instructable to add a heat bed to the Type A Machines 2014 but I cant get the heat bed to work.
