Supposedly some sort of people asking for STLs situation caused it this time.

But honestly, I think the real reason is that Reddit doesn't want 3d2a anywhere on their site. It's the only reason I can think of why they keep banning 3d2a subs for "rule 7 violations" when all of the subs are very clear that anyone who asks for files will get banned. If reddit was operating in good faith they'd allow the sub mods to follow their own rules and issue bans before leaping to nuking the whole community.

I can say that my Q2 has been a joy to use. Every issue I've had with it so far has been user error. (Polymaker recommends no fans on their ASA. No, the ASA yearns for the fans, at least when your chamber is heated.)

And if you're posting here, you probably want the option to print with high end engineering filaments. The P1S "can" print PA6CF, but you're gonna need to upgrade it. And if you want to run something like PPACF? Gonna need even more mods.

The Q2 handles everything short of PEEK/PEI like a champ right out of the box.

But the Q2 is a brand new printer released three months ago, so don't expect it to go on a good discount any time soon. But honestly, $650 isn't a bad price for what you get. So yeah, I'd say go for the Q2 if you're posting here. The Q2 is probably dollar for dollar the best guncad printer around.

Note: I can't speak to how good the Box/Qidi AMS is. Because I ordered the Q2 Combo on week 1 and they still haven't sent my box yet, apparently because they just released a new revision that fixes the big pain points of the design and they're shipping that out instead of the v1.0 Box.

You mean a PDW kit? Most people associate pistol carbines with stuff like the Urutau or DB9 or stuff like that, not with chassis for handguns. PDW is the tearm most people use for what you're looking for.

Anyway, I've never made one, but the Super Patriot has STEP files, so you could remix it for a Hellcat slide as long as you've got the measurements right. https://guncadindex.com/detail/Super-Patriot-PDW-Blank-Series:e

MA should probably be red because our state doesn't just specific recoil mode of operation, but anything designed to mimic fully automatic fire.

Qidi Q2. Hands down the best 3d2a printer, dollar for dollar.

280x280 build space. It's got the heat to handle anything short of PEEK with a 370c nozzle and 120c bed. It's got the heated chamber we want. It's got a bed probe that isn't degraded by heat, unlike most leveling sensors on the market. Like most modern printers, it has hardened steel nozzle and extruder components, so it can handle CF out of the box. It has quirks and isn't perfect - I dislike how the poopchute is almost always open rather than almost always closed, which makes the chamber heater slightly less efficient - but for the price it's impossible to beat.

Mine has been a joy to use.

What kind of PAHT-CF are you talking, though? Each brand is different stuff. Siraya PAHT-CF is PPA. Elegoo is... PA612CF I think?

On paper the CC can handle PPA-CF since the hotend gets up to 320 and it's hardened bimetal. It's a good machine too from what I'm told. I've never used it, but everyone I talk to likes it.

That said, the Q2 is probably going to be a lot better for this hobby than the CC because of the heated chamber. That one I have used - I've got a Q2 and I love it. It has a couple extremely minor pain points and if you're going to be printing CF filaments you really want a 0.6mm nozzle instead of the stock 0.4, but it's a seriously excellent machine and it's basically ideal for guncad purposes. If you're seriously looking at engineering filaments, the Q2 is the one to get. Heated chambers do so much for layer adhesion, and it feels like layer adhesion is always the first thing to go when a print starts failing in use.

I have no idea how well the box works with the though. I bought the combo and they haven't shipped the box yet. They said within two months and I bought it on week 1 so hopefully soon.
