Extruder heat would go up with printing with heatbed I have face a weird issue, when i was printing my extruder temperature will drop to 215-219 as a preset was 235, but when i never turn on my heatbed, my extruder can go up to 235 & higher, I have put a relay on my heatbed but still having this issue, should i add relay to extruder or maybe have a spoilt somethings, anyone can advise???? sincerely appreciate any kind help...... https://reprap.org/forum/read.php?2,741913,741913#msg-741913 Sun, 12 Jul 2026 04:35:51 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?2,741913,743851#msg-743851 Re: Extruder heat would go up with printing with heatbed https://reprap.org/forum/read.php?2,741913,743851#msg-743851 evetanlm Developers Mon, 30 Jan 2017 23:53:35 -0500 https://reprap.org/forum/read.php?2,741913,743845#msg-743845 Re: Extruder heat would go up with printing with heatbed https://reprap.org/forum/read.php?2,741913,743845#msg-743845 evetanlm Developers Mon, 30 Jan 2017 22:30:19 -0500 https://reprap.org/forum/read.php?2,741913,741945#msg-741945 Re: Extruder heat would go up with printing with heatbed https://reprap.org/forum/read.php?2,741913,741945#msg-741945 Or maybe your wires from PSU to controller are to thin and cause voltage drop.
Another issue might be, the FET for the extruder is not fully ON, because the 5V rail is somewhere around 4.5V-4.7V. ( Happens mainly on Arduino Mega with Ramps and graphic LCD )]]> o_lampe Developers Wed, 25 Jan 2017 02:19:25 -0500 https://reprap.org/forum/read.php?2,741913,741913#msg-741913 Extruder heat would go up with printing with heatbed https://reprap.org/forum/read.php?2,741913,741913#msg-741913 evetanlm Developers Tue, 24 Jan 2017 20:23:35 -0500
