Is the cooling fan mount supposed to be so low. It is just above the hotend position, which is fine, but the bed bolt at the Y extent is in the way. I lose about 20-30mm of Y travel with the current design. I already had to remove material from this part to get it to mount higher than the hotend. . But just curious if it is meant to be higher still.
Hmm no the part isn't meant to be that low! I'll have to look into that but there should be about 3mm of clearance from the bottom of the fan to the print head. Are you using an e3d or e3d lite?
I'm using a knock off hotend but it is dimensionally identical.
I think the issue is this :
It was very misaligned. And I had to remove material from where it wraps around the gantry.
I did check against the delaminating x gantry that you had printed and it was the same. So must be the just the blower piece. I'll try printing one off and see if it's the same or comes out differently.
I too had this problem with the fan shroud not lining up / sitting too low on the gantry. I had to use a small file to grind away the lip so it would slip under the gantry properly.
I've run into this exact problem. I didn't know if it was something I did wrong, or if it had anything to do with when I printed the fan duct and X-gantry out. I'll probably file the duct down as well. The main problem I'm running into right now is that the hot end sticks out too far. The build platform hits the nozzle before the z-endstop clicks. I'm not sure if this is due to using an off-brand hot end (that's probably it), or if printing dimensions where things line up are off. My bet's on the knockoff hot end. My E3D should be in soon though.
Did you crank the leveling screws for the bed all the way down (springs fully compressed) first?. That should give you plenty of gap between the bed and hot end. Otherwise maybe it is a dimensional difference with your hot end?
