The area of concern, in my opinion, would be covered by the heat shrink.

I'll be needing to cut the heat shrink off of mine and inspect. But I expect they are OK because I have been running 65 deg print bed 205 deg nozzle on prints exceeding 24 hours. (high detail lithophanes)

Do these XT60's look ok? I sure wouldn't want a fire. Havn't a chance to do a test print yet. Was going to work on it tomorrow. I'll check the solder joints then.

[rifleman_btx]

I totally agree, thats one i wouldn't trust at all.

[fhhuber]

Keep an eye out for this!

Even the "OK" (by his grading) soldered ones actually have marginal to poor solder joints.

Nice prints! Oh my God what a job putting the Ender 3 together. Had to use YouTube for most of the build. Now I have to figure out how to work it. lol.

[Dirty Dee]

A few minor changes and I think I might have something usable :Cool:

[rifleman_btx]

LOL thats how i feel about my stuff as well hahaha

[Elbee]

Im thinking better firmware might be it, as they are both running .4mm nozzles.

That is my thought. Each time a upgrade to the latest firmware, the prints just get better and I know I'm not doing anything differently. LOLI'm just not that smart. Best, LB

LB, Funny you should ask, had to put that on hold because the Cessna went in and i have to reprint and replace a bunch of parts for it. And then i think im gonna go for the 64" Edge 540, then the PBY. After those are ironed out, i have the F86 myself. Man these printers given me the bug LOLon a side note the prints coming off the new printer seem alot more fuller than the ones off the anet. Seems to be an even brighter white

RMBTX, A difference in nozzle size or even firmware? Sounds like it's a good thing no matter. LOL Best, LB

LB, I did pick up the F86 as well so cant wait to see how yours works out

RMBTX, I know I am delinquent in the work there with my F-4 build. So far all parts are good, though again, these are PLA. I hope I do not regret that. Like you, I had some super thin walls and thought I'd back those areas with CA and .6 fiberglass cloth. I will need to research all the component parts as I have none: EDF, motor, retracts etcetera. How's the PBY coming? Best, LB

[rifleman_btx]

Yes indeed, what is nice about my unit is the control box is a separate unit to the machine itself. But even still with a 310x310 x410 build area it will need a very large box plus the 24v system vs my old one that was only 12v

My plan for an enclosure is to use coroplast for the main walls and top. Just enough frame to hold the lightweight stuff together and allow hinging a section of plexi as the door.
Very cheap materials except the door.

And I found you can 3D print the hinges and door latch.

Don't forget the enclosure DOES need air exchange with the room or air in from the room and ducted to exhaust outdoors. Its pretty easy to make an oven. The Kenner EZ bake just uses a 100 watt light bulb to bake cookies and small cakes. There's more watts of heat production in an Ender 3 than that.

I need to do that but now i need a really big box!LOL

[Dirty Dee]

I do. Here is a picture. Basically, it keeps out any drafts and helps increase the ambient temperature in the "chamber" to the mid/high-80s.

When I print with ABS, the cooling fan is disabled, but this does have a bit of a drawback. For any small sections, the sections can get a bit "melty" looking due to no cooling. To address this, I usually print parts in pairs or more. This allows a bit of time for the layer to cool before the next layer is extruded.

[Woodcock]

I'm using ABS. Havent bought any PLA in over a year. Acetone welding doesnt work on PLA

Hey Dee, did you have to box in your printer using the ABS?

Woody

[rifleman_btx]

Very cool! Once i get all these projects done im gonna look at doing that kind of thing as well
