Temperature control in the N2(+) enclosure

My next mod project is to add heating/cooling to the N2(+) printer enclosure. I'll keep this thread going as a running log of the project. My printers live in the garage. It's attached to the house which tempers the thermal fluctuations, but between winter and summer the temperature in there can go ...

Re: Cannot get a good print

What are your printer settings for single nozzle? I tried so many with some being much worse, but very few changes improved the prints. When I get home I am going to try the couple of changes mentioned above. The slightly lower nozzle temp is the one change that had a positive change. I had increas...

Re: One extruder or dual-extruder?

Thanks zemlin. In that thread, people talked about the weight a lot. So, what is good about having a lighter extruder? The gantry carrying the extruder is capable of fast, abrupt movements while printing. There are also a lot of components in the system that can act as springs causing resonance and...

Re: One extruder or dual-extruder?

I've been doing the 3D printer thing for a couple years. I bought an N2+ in October and an N2 earlier this month. Both the machines I bought are dual extruder, even though I've only messed with dual materials a couple times. It's a $200 option, and if you bought the parts for a full hot-end you'd be...

Re: Cannot get a good print

Was hoping the speed and dual extrusion would speed up the process. Alas it must just be slow and steady. Have the slow trying to find the steady. If your parts are less than 25mm wide you might be able to run both barrels at the same time creating duplicate parts. I've never tried that. You need t...

Re: Dual extrusion Simplify3D

If you are printing two separate models, create a process for each of them - one process with the right extruder, one with the left. Then assign the appropriate models to each process. When you slice, select all processes.

Re: Mount for moving the Y-axis limit switch

When installing this bracket on my new N2, I discovered a mistake in the design. The pocket for the switch is not big enough so the switch doesn't fit down as intended. My apologies to the four folks who have downloaded the file. The STL has been updated with a corrected design.

Re: Clips for the glass plate that Never interfere with the nozzle

That's one of the things I addressed with my bed modifications. The clips are outside the 12"x12" build area. The platform I show in the photos is 12"x12" aluminum with ePC hold downs, but if I put a glass plate on the machine I have a 12mm border on the front for the clips. Tech...

Re: PETG Settings

Excuse my Ignorance, but why do i want to stick PEI onto glass ? I've always used PEI bonded to Aluminum, so I can't speak from experience, but I believe ABS would pull enough on the bed that it would not remain flat without a rigid substrate. PETG doesn't have nearly the warpage potential of ABS, ...

Re: Grounding out the filament guide tube

Are you talking about a house-zap, or a static shock? If static, that tubing is not conductive so grounding won't accomplish anything - those electrons won't go anywhere in a material that doesn't conduct.

If it's a house-current zap, you have other, more serious issues.

I've been using my N2+ which has the Dual Direct Bondtech and an N2 at the day job which has the stock extruder.

Re: New Acceleration and Jerk settings

Or do I have to calibrate the values? And if so how? It's not the sort of thing that has one right answer. Speed, acceleration, and jerk have a big impact on build times, part quality and appearance. You need to find the balance point for your prints and what's most important to you. For me it's be...

Re: My bed mods

Bed clips in the build area is a pretty common practice on desktop 3D printers.
I need to run a modified firmware to reach the limits of the build surface since I've extended the Y-axis travel, but with that I have printed a 12" circle.
