Re: Best practices / recommend mod list.

In my experience, many of the common mods ended up having trade-off's that outweighed the benefits, so they got removed. I realize that what I'm about to say will be blasphemy to some, if not most, of the veterans and newbs alike on here, but its still worth a mention if you ask me. I know everyone ...

Re: Printing in POM/Acetal/Delrin with the M2

If your 2 choices are an M2 and an ultimaker, I would immediately choose the M2. I have done some experimenting with POM, and its not a walk in the park to print with. It has refused to stick to glass, untreated MIC6 aluminum, and PEI so far. I had some success printing it on FR4 perfboard, but that...

Re: PEI Filament

I just picked up a small roll of the 3dxtech ultem 1010 filament, and the other upgrades (PT100, and FR4 perfboard) to print with it. Once I am done making my enclosures, this is next on the list to start working with.

Re: Fume-blocking Enclosure

I did my first print with my enclosure tonight, and it was with the bed at 90C and the nozzle at 275, and the air at the top of the case only reached 30C after an hour. So I am probably over-designing the heat exchanger.

I'll post pics of my enclosure in the next couple days

Re: Fume-blocking Enclosure

Well, after further consideration, I will be returning the HEPA filter and activated carbon prefilter that I bought for this purpose and I'm going to get a ULPA filter instead. They capture down to 100 nanometers, so hopefully that will be adequate for my filtration needs. Ed, with regard to needing...

The 2 blowers was in reference to the filtration enclosure.

Re: Fume-blocking Enclosure

Thanks for chiming in Ed. Unfortunately its not very realistic for me to give the rambo fresh air, but would it be acceptable to get some of those mini heatsinks for stepper drivers and raspberry pies and place then on the drivers and MOSFET's, and then upgrade the fan in the electronics case, and h...

Re: Fume-blocking Enclosure

After further consideration, I've decided to make mine a recirculating filtration setup, and just try to filter the air inside the case as much as possible. I'm thinking that if there are UFP's being emitted, that I'm probably better off keeping them contained within the enclosure for long prints, r...

Re: Fume-blocking Enclosure

I'm currently building an enclosure as well. My filtration was going to be single pass, with an arduino to modulate the fans pushing air into the enclosure with the filter situated at the top where the air vents out. My logic here was to keep the temp of the enclosure regulated, assuming that it cou...

Re: Irregular Wall Surface

might wanna confirm that your hot end doesnt have any wiggle to it, and that the bed isnt able to shift at all, meaning the print surface OR the heat plate.
