CR-6 SE E3D V6 Mount

thingiverse

A mount for an E3D V6 All Metal Hot End to fit on the CR6-SE. I had found another but it was built for a clone, and the geometry of one I have appears to be different at the top where the mount would go, so I had come up with something on my own. The cooling situation is still not ideal as mentioned below. I've only been doing CAD and 3D printing for a few months and this is my first shot at this. But, the scad file and stl are both included if you need adjustments (please ignore what is probably some terrible looking scad code). And, use at own risk. I'll try to provide as much info as I can here to help. All I can say is; it is working for me. This uses the existing screws and is a single piece. I printed in PETG with supports on the build plate at 0.2mm layer height and 100% infill using Cura 4.8 on the CR6-SE. The PLA prototype I printed snapped when trying to get it around the top of the heat sink. Could just be the cheap PLA I have. But, based on that I wouldn't really recommend that. Once printed it, it was quite snug around the top of the heat sink and once screwed in place it is holding fine and isn't moving at all. In addition to double checking that it is tight. Once in place and wired back in and turned on I recommend double checking that the blue light for the strain gauge is not stuck on solid blue and that it does light up if you nudge the hot end toward the daughter board. If not, you may need to tweak the potentiometer on the board. The mount shouldn't interfere with this, but sanity checks are good. Another thing to check after is that this hot end is taller than the stock one. It wasn't long enough to interfere with the optical end stop in my case. But, verifying this seems prudent to avoid smashing the hot-end into the build surface. Also, not sure if it fits in the stock fan shroud, haven't tested that. I'm using this: https://www.thingiverse.com/thing:4669393 And lastly, I printed a spacer which is also included in the files to increase the length of the parts cooler tip so that it doesn't blow directly at the heater block with the added height. Might need to revisit that later. Since it is angled, it moves it both down and forward. Though, in general I would say that the position might actually be better for parts cooling by a bit than the original. I just finished that though and haven't printed with it yet. Need to see if it poses a melt risk to the tip. [update] Added a v2 of the fan spacer. While I like the positioning of the original one, it was so low it would bump the locking mechanism for the build plate and was just too close to the print surface for my comfort. The updated one reduces the spacer by 1.5mm which still leaves it is a better spot than without it, but doesn't get in the way any more. Also, I needed to use the side cutters to trim off the corners of the screw holes that go into the blower fan. I may introduce a v3 at some point with that included in the design.
