I've never had a problem with moisture getting into the bags. Just don't put the filament in over your sink. I squeeze as much air out of the bag after I put the roll in. BTW, you should be able to get the bags at your local grocery store. I get mine at Publix. Get the thickest bag you can...

I keep my filament in 2 1/2 Gallon zip lock bags with some desiccant (most likely silica gel). You can get desiccant cheap at air conditioning supply houses. They use it for commercial refrigeration dryer/receivers. Most of the desiccant they sell changes color to blue when it is wet., pink...

Hate to disagree, but I have personal experience with belts. With the Prusa, I was getting layer shifting, even the y axis belt was fairly snug. I put a tensioner on the y axis belt, and much of the layer shifting went away. Inexpensive 3D printers SHOULD NOT require constant tweaking. Yes...

It's still a notched belt drive. You can see the belt in the just underneath the extruder. I hate notched belts because they stretch and needed to be carefully tensioned. The old plotters I helped design used flexible steel cable around a pulley with a spring tensioner. Neat design. 3D...

Perhaps Prusa printers are much higher quality than the Chinese printers, but I wouldn't know. All I know is that I had a bad Einsy board and needed some additional Y rod mounts before the thing would come together. I also had to shim things a bit to get them to align. I don't know the...

Yes, that is 18 Gage speaker wire. Unfortunately, it doesn't have polarity markings, so I had to use an ohmmeter to properly wire them. The panels are polarity sensitive. I use a adjustable bench power supply to test everything. I got the panels here: https://www.goldmine-elec-products.com/...

As per popular request, the front view. I just stuck the LED panels on to see how they would light up the printer bed. I got the panels from a surplus house. The panels run on 12V, so they are wired in series. These are left over from another project. I'll permanently mount them when I find...

Well, I finished my new Octoprint box using a RPI2B (had one around), built a case for it, and have it running off the 24V printer power supply. I added two big LED lights to light up the printer bed that I can control from Octoprint. Here are some pictures. I designed the case using Alibre...

Nope. What will happen is that the belts will snap, or at a minium will stretch and/or the stepper motors will burn out. You can't throw that extruder carriage around like that have not have something happen. The old plotters I designed used really heavy servo motors (Slo-Syns) and very...

Sorry, but I'm not taking anything out of context. Depends what you define as "fun". Perhaps this is the wrong forum for me to be in. RE: Color Management The very thought of these words means that you are not satisfied with the colors you are getting on your printer. You take a picture...

Depends what material you make the toilet roll holder from. Using Alibre Design Expert, I could model a toilet roll holder in about 10 minutes so you can 3D print the pieces, but then, I am very familiar with a powerful tool. 3D design can be VERY difficult or not so difficult depending on...

You might look at FreeCad. I have been playing with it, and it's not bad. It does feature-driven modelling, which means you build up a model feature by feature (features are the things you add to a model, like circles, spheres, solids, lines, etc.). Then, you can go back and edit a particular...

Congratulations on getting your printer running. I'm still waiting for the return of a defective motherboard for my new Prusa I3MK3/S. I still have the Flashforge Creator Clone (Monoprice Maker) running fine. I'm curious what design software you use? I did a commercial project and have...

Two totally different things. To do color management well, you need to be able to profile your monitor and printer. For that you need a colorimeter or spectro. Then you need a monitor that can be profiled (many of then cannot). Expect to spend at least $1200 for a monitor that can be...

Thank you. I have put quite a bit of thought into a large 3D printer from an engineering standpoint. I have a small Chinese Prusa-type printer in addition to the Monoprice clone, and that printer is a piece of junk. I have modified the Monoprice clone and it works fairly decently now. I...

I have posted here before, but I'll introduce myself. I am an electrical engineer with a great deal of knowledge in programming, system design, and network design. I also do some mechanical work and like to design things for 3D printing. I use the Alibre software for design, and Simplify 3D...

1) EE is an Electrical Engineer. I have a Master's in Electrical Engineering. 2) The CR10 is about as big a printer as you can make using the RepRap design. Look at the reviews on the TRex, which is 500 x 500. Problems scaling up a printer are: Frame stability-You need a different frame...

Perhaps there is little 3D printing on the forum because there are lots of forums dedicated to 3D printing.

How do I post things? I was considering getting a Creality CR10, but I wanted something that I didn't have to futz with. 3D printing is not my hobby, making things is. One day, I am going to build a 2' x 2' x 2' printer using commercial closed-loop motion control stuff. I have come to the...

Perhaps no one is having problems. I try to figure out my 3D printing problems myself. I have an ancient Flashforge Creator clone from Monoprice, and have just ordered a Prusa i3Mk3S. I use Alibre for design, and Simplify 3D for slicing. I make parts for stuff around the house, and the last...
