I figured to mount a 50mm fan blower on the back of the extruder so it can plug into a duct that will take the air under the extruder and around the hot end. I am working on the 3d model to add some tabs so it can hang from the 2 - 3mx45 bolts holding the bottom of the extruder back and front plates.
I have also added a bolt under the Z axis with the bolt head up about 1/2 inch above bed-base plate, so I can micro adjust the z end-stop.
I ran the Y axis cable chain up and to the bottom of the top back rail. (the extruder assembly hits it if you run it down like the manual says.
I moved the controller board mounting down and to the left as viewed from the back. This gave me more room between the power supply and controller board.
I ran all my wires down the right - rear vertical Extrusion so I did not have a big bundle strapped to that extrusion. Some wires went into the front slot, some went into the left side slot, and some went into the center hole (I drilled through the slot and into the center hole and ran them down and back out Then I ran them out a hole in the lower part of the extrusion, and through the side of the control and power enclosure.
I used a XT30 connector to make the top disconnect for the hot end heater wires, and one that I ran 3 fans into so I had one wire making the actual connection to the power supply. Running the 4th (part cooling fan) into the Fan connector on the controller board. I added a fan to the controller/power supply enclosure to pull air through it to help with getting hotter air out of there.
Dan : What do you do when you remove a print?/
Cork sheet, with aluminum tape covering it with kapton tape on top of that.
I made 2 glass / PEI build plates, so I did not use heat sink compound. It would be too messy to remove each time you had a print to remove from the bed. Unless I make a plate to set the 2nd build plate on to cool, and hold the build plate for removing the print once it has cooled. hmm I could have one on the bed, and one on the plate at all times... That might just work so I would not have to remove any compound from the bottom of the plate.
I do not see a way to attach pictures...or I would add some small pictures to show you.
