I need to know were to buy a new set of screws and the special nuts that hold the filament role holder down to the top rail on my Ender 3 Pro 3D printer. I had to take the filament role holder off the printer so the printer would fit in the box. The screws and special nuts were put in a ziplock bag for moving to the new apt. Everything for the printer (printer tools, filament roles and so on) arrived safe and sound except for the ziplock bag with the screws and special nuts in the bag. I have been looking high and low on the internet as to where to buy them with no luck. There is 4 ways I can go to clamp down the filament role holder. 1. clamp it to the table with a C clamp, 2. use wire ties to clamp it to the top rail, 3. use the C clamp on the top rail, 4. drill 2 holes in the top rail and use regular machine screws and nuts. #4 I don't want to do unless there is no other options that will work. I would rather buy a new set.

Thanks for the info. I did manually move the Z screw rod up in-order to make it easer to unscrew the nozzle so I could clear the nozzle. I guess I didn't screw the Z rod for the nozzle down far enough. Though I don't know how to tell when I hit the limit switch. I am still learning the whole process of 3D printing.

Ambassador, Since the last post with the error message I got Cura working and I have been printing STL files from Thingiverse until today. The filament got stuck in the nozzle. See the post (a problem with a stuck filament)

I was trying to change the filament and the filament wouldn't back out of my Ender 3 pro 3d printer in the normal way. I had to unscrew the nozzle because the filament was stuck in the nozzle. After unsticking the filament I screwed the nozzle back in and re-feed the filament in. The bed leveler program isn't printing right. See the 2D drawing (the drawing isn't exactly to spect's). Auto nozzle home is in red in the drawing. The blue circles and blue lines are where the 3D print is messing up, some of the squares and lines aren't staying stuck to the bed even with the glue. Before I tried to pull the filament the normal way and before I unscrewed the nozzle. The printer was working 100% aok. I have already 3D printed a few files. I messed up somewhere.

I would like to learn how to modify the file my self. To increase what I know.

I still have the Gateway laptop model NV570P-18U as a backup computer. But now I also have as my primary computer, a Gateway tower model FX-6840. The Toshiba Satellite L455-S5000 laptop kicked the bucket.

To GregValiant I have a bit of a head start. I have an AA degree in electronics and I used to install in car's and truck's/repaired car stereos, 2 way radios and so on, I also repaired tv's, stereos, vcr's, and computers. My 1st computer was a Commodore 64, then the whole commodore line, then MS Dos, then the Windows line starting with Win 3.0. I also know tube and early transistor theory. But I am not a computer programmer. Computer programming is new to me and I am a slow learner with dyslexia.

1st all the filament that I have is all PLA. 2nd All of the filament that I have is 1.75mm except for the 2 large gray reels. The 2 large gray reels are filled with 2.85mm filament, and I don't know what I am going to do with them. The eBay seller that I got the 2 gray 2.85mm reels from has a NO return policy (ASIS). And that is my bad. I didn't check the filament size before committing to buying them. right now I only have 1 large reel of 1.75mm filament, and that 1 large reel of 1.75mm that I have is multi color filament. Right now It doesn't matter if the prints are multi color. I am just practicing how to make prints and to use MS print 3D. There is 1 stl file that I would like to print. https://www.thingiverse.com/thing:4907266 But I need to figure out how to remove the person's ham radio call letters (that made the above file ) in the stl file and insert my ham radio call letters into the stl file before printing. I will buy a large reel of solid color 1.75mm PLA before printing this project.

The printer has a pause button built into it's menu. The reason I need the pause is to change the filament reel. I only have the small 1.75mm reels that came with the 3D pen. Those small reels don't hold enough filament to print 1 project that I am trying to print. I tried using the pause built into the printer to change the filament reel and when I unpaused the printer. The lines after the pause weren't sticking to the base that was already laid down, there was lines going everywhere. So I aborted the print.

I have 2 large 2.85mm dia gray filament reels. Can I use these reels on my (stock from the factory) Ender 3 Pro 3D printer? A 2nd question. Is there a way to pause the print to hang more filament when the 1st role gets close to running out.

I found the Paint 3D prog when I installed Win 10 Pro on the new/used used tower that I just got. What a dog, pushing that tower into place on the rug next to the desk, BIG time ouch!!! on my joints. 😞 I plain to buy a strip of plastic to put under the tower. It should make it easer to slide the tower in and out.

I know PLA is biodegradable but I am sure not going to eat it nor would I feed it to my dog. I was just curious as to what happens to the used left over PLA. At the rate that I am 3D printing I will be in an assisted living home before I fill the 1st box with used left over PLA. :-)

At this time I don't have a lot of left over used filament. But over time it will build up, what do I do with it? The local recyclers don't take used 3D printer filament and the Benton County land fill will charge me to dump the used filament.

I found under the "P" programs. Thanks
