Removing Crimps from Hotend Connector? My Ormerod1 developed a heater fault. When commanding the Hotend to 200°C it did not take long until the a fault developed: "temperature excursion exceeded 15.0C". Ok, I dug around a bit and I think I found the problem: [attachment 110951 HotendConnectorSmall.jpg] yes these wires are supposed to be yellow. it's one side of the hot end heater. During testing i noticed that the wires and connector to the hot end where warmer than expected. Now, any hint on which side I should poke something small in the connector to try and dislodge the crimps from the housing? If possible I really would like to have a closer look at the single crimps ... thanks for all your feedback auser https://reprap.org/forum/read.php?340,851225,851225#msg-851225 Fri, 04 Sep 2026 20:04:55 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?340,851225,856007#msg-856007 Re: Removing Crimps from Hotend Connector? https://reprap.org/forum/read.php?340,851225,856007#msg-856007 I have already replaced the connector so I believe it must be as a result of the connectors not making 100% connection with each other.
Both the wires are charred on my printer at the connector.

I discussed it with Sardi in his post here]]> Karoo Klong Ormerod Fri, 05 Jul 2019 03:38:40 -0400 https://reprap.org/forum/read.php?340,851225,851367#msg-851367 Re: Removing Crimps from Hotend Connector? https://reprap.org/forum/read.php?340,851225,851367#msg-851367 auser Ormerod Tue, 16 Apr 2019 03:54:35 -0400 https://reprap.org/forum/read.php?340,851225,851346#msg-851346 Re: Removing Crimps from Hotend Connector? https://reprap.org/forum/read.php?340,851225,851346#msg-851346 Got one out with staples and some fiddling, got impatient and sniped of the rest. Also ordered some XT30 connectors, ... for the moment it is printing again with the wires temporarily soldered together. now the leads stay nice and cool, let's see if the print will finish.
Thanks to all hints and tips!

It's difficult to remove the crimps without the proper Molex tool.

Difficult, but not impossible.

Neat!]]> dc42 Ormerod Mon, 15 Apr 2019 10:23:03 -0400 https://reprap.org/forum/read.php?340,851225,851301#msg-851301 Re: Removing Crimps from Hotend Connector? https://reprap.org/forum/read.php?340,851225,851301#msg-851301

(Just going off memory here, do check with the circuit diagrams. )]]> aniron Ormerod Mon, 15 Apr 2019 02:32:21 -0400 https://reprap.org/forum/read.php?340,851225,851243#msg-851243 Re: Removing Crimps from Hotend Connector? https://reprap.org/forum/read.php?340,851225,851243#msg-851243 dc42 Ormerod Sun, 14 Apr 2019 12:57:25 -0400 https://reprap.org/forum/read.php?340,851225,851225#msg-851225 Removing Crimps from Hotend Connector? https://reprap.org/forum/read.php?340,851225,851225#msg-851225 [attachment 110951 HotendConnectorSmall.jpg]
