Looks like the $47 printers are gone from ebay now. They have an $80 Ender 3.
Neal,Good Day all,
Just found this forum and it is great to find some other crazies working with additive manufacturing.
6 years ago I discovered the tech, but could not find any reliable machines. Also, they were REALLY small build surfaces. 12x12x12 was HUGE then and very expensive.
I wanted a large build area and I wanted leadscrews instead of timing belts for the axis drives. No one offered one for less than "WAY TOO FRICKEN MUCH", so I designed and built my own.
It took 5 years and 4 different designs to find what I wanted. And I thought building planes was hard and time consuming... But I finally succeeded. I now have a 24"x24"x18" printer with a heated bed. I am building a 36x36x18 now to join it. Both use the Azteeg X3 pro boards and leadscrew drives. I use 2 screws for Y, 1 screw for X and 4 screws for Z. I still have room for two extruders.
I have been playing with this model for a year now and have about 2500 hours on it. I have tried printing every thing except PEEK. My extruder can hit 500c and my bed 150c, so I know I can print it, just haven't had a use. The best stuff I have found so far is NylonX from Matterhackers. It is Nylon with 30% chopped CF fibers added for strength and stiffness. It is all I use now. Kinda expensive, but LIGHT and STRONG, so worth it. Also, don't even think about trying to print with out a 75c degree bed. and purple glue stick.
What I have found is that PLA. PETG, and PLA Tough are all "TOY" materials. Great for desk items, but maybe not really suited to our environment. PETG with CF is stiff, but brittle. PETG solo is just very brittle, not stiff. PLA degrades way too fast. PLA Tough is better, but it is still PLA and not what I would consider durable enough for an aircraft part. PETG is durable and will stick without a heat plate, but I have found it to be so brittle that a part broke just dropping it on the floor. I printed a wing core with NylonX and drove my van over it. It just laughed.
Sorry to ramble, just happy to find some fellow minds. I am anxious to draw on the experiences of others and happy to share my experiences with any newbies trying to find their way to the hobby's greatest gift. The wonderful (not) world of 3d printing.
I hesitate for you to put much time into it as I did the drawing very quickly....it is to scale ....if you want can go to Fusion 360 or send dxf or figure something out. I should spend lots more time to 3D model the male connector...Do you have a picture and dimensions? I have a little time while I'm waiting on some prints and might be able to conjure something.
are you going to get your money back?eBay pulled/closed all of the listings.
Nope! I resisted the urge and double checked the vendor.are you going to get your money back?
Hotwings what price are you looking for on an ender5? Is the previous version ok or are you hoping to find the newer larger one used? Reason I ask is many want to upgrade to the larger now and I could post on the FB group to see if anyone has one for sale. Also where are you located?"Nope" - as in I never gave them any money. Can't get back what I didn't spend
I tend to check out who I'm dealing with when the $'s get over about 50.
Thanks for the offer!Hotwings what price are you looking for on an ender5?

od of thread measures .45 but I do not see a M11.5 thread so it could be M12x.75 or M11x.75 or some special electrical part.
the joy of reverse engineering.
made 3d model and .stl file, now to see if you can see/use them
