For empty spools I bought some of these: http://www.filabot.com/collections/frontpage/products/empty-filament-spool I realized by looking at them and seeing the stiffness of the filament that these would not work well for holding filament. The main issue is the hub size is too small. These spools ar...

Anyone seen this? http://repables.com/r/143/

Notice who made this model. When I get my machine up and running I may have to test these out.

Well, it powers up so far.

Update on JB Weld holding thermistor: When I hold my hand on the aluminum of the hot end (off of course) I can watch the temperature change on the NOZ reading very fast. So the sensitivity of the thermistor seems to be good. I am getting reasonable concurrence of temperature between my NOZ and BED ...

Since JB Weld and the glass thermistor are weaker than carbide steel, then I can just drill and re-tap the hole. The only reason I tapped the hole in the first place is because it a convenient way to roughen the surface for the epoxy. There is nothing permanent about it. In addition there is the opt...

Okay, this is weird. I ended up missing 2 x 1" Pan Head screws. What is really weird is this is the step where you mount the brackets to the display board. However, I have a bag with 2 x 1" Flat Head screws and 2 x nylon/steel nuts. So is this just a case of a screwy mix up? I don't need t...

Alright, I am going to try using JB Weld (2 part version) that handles 550F according to package. In places online it says 600F so I am guessing the 550F is a CYA statement on the package. 550F is 287C Celcius. So that should be enough. If not I will report back. Also, I took a 4-40 tap and tapped t...

don't trust it as an adhesive on it's own I am assembling my hot end (putting wires on it) and the thermistor popped out. I don't think the rtv is a good solution for holding it in. It is not act like it was "stuck" to the metal at all. I am thinking I may get some JB weld to hold it in. ...

Even better: get a MIG torch on there with a little computer control over the wire feed and have yourself a metal printer. Ooh, I will talk to my mechanical engineer friend and see what we can do. That does sound like fun! I did think of one thing running a non-standard voltage "might" be...

You are right. Maybe this is not a good application for this. I forget my plasma cutter is like %99 carbon steel tubing. Good point on the extra torque might cause issues with the framework. I am mainly electrical so I tend to assume some things. I thought I saw things on this like missed steps beca...

Such things people say...
...are turning out to be true these days...

A few years ago myself and a friend built a plasma table using a hand plasma torch, stepper motors, some stepper drivers (Gecko), and a 4'x4' metal table. We found out that running at higher voltages and low current (within wattage rating of the steppers) we could get more rigidity, speed, etc. We s...

The question is how is the patent worded? If it is specific to 3D printing (as in additive printing) and the software produces G-code then anyone could write software to create tool paths if they don't describe the end use (this avoids process patents). So software patents for 3D printing tech could...

Are you serious? Several thousands dollars for that? I would be better off buying a Taig CNC Mill, putting my extruder and hot plate on it and calling it good. Which is one option I looked at before settling on the Rostock. I would end up with a nice CNC metal mill and a 3D printer.

"It is important to remember the dimensions you designed your part in. Centimeters are not equal to inches." "We are working with Filabot to create a 50mm filament extruder. While this is not the final material to be used it does give you an idea of the brass nozzle we will use for th...

I vote some weird fungus or single celled amoeba that eats cardboard and then blows up leaving no residue while spreading is spores. Either that or an alien escaped its packing and is eating any biologics or biologically based material (poly). In either case: it is ancient, scary, and you need The D...

Thanks for the awesome welcome!

Getting closer on my build. Some parts were a challenge, but a really good instruction manual.

Number one: The news is mostly lies. Number two: One of the few companies actively complaining about the US government walking all over our privacy and tracking us is Google itself. They are actively working to defend digital privacy of individuals and companies. They speak out against the secret me...

Well I just switched them back. Was not that hard to reverse them again. Thanks for the info. I will remember when I get to building more of these. Of course I understand a new bearing assembly is in the works.

Okay, I got the inner plate direction of the cheapskate wrong on all 3 assemblies. The reason I got it wrong is because I thought the manual was telling me that I should line up the inner plate with the eyes pointing to the right, then attach the plastic piece to the front of the inner piece in that...

I used to do a lot of government nuclear work. A burp like that is really not that significant, but it always gets blown out of proportion. You will get way more uptake with all sorts of radionuclides at a coal fired plant. You have to take it seriously, but it really makes everyone run around like ...

Hello everyone! I am mid build on a Rostock Max V2. I do robotics engineering and controls integration. I needed a 3D printer to make custom electrical boxes for inside tight spaces. So I experimented with 3D printing services. Way too expensive so I purchased a Rostock. The more I research about 3D...
