3D Printer / CNC discussion thread

@Izerous If you have a Lowes near you the DVX12P-QTA model is $179, or can be ordered from Rona. https://www.rona.ca/en/product/dewalt-120-v-12-ga-55-hp-corded-portable-vacuum-dxv12p-qt-45585046

I've been looking for a quieter shop-vac and this is on my radar.

Good find thank you. I started looking at 1HP dust extractors and stuff and found https://www.busybeetools.com/products/dust-collector-1hp-570cfm-1-mic-bag-csa-ct053.html with a suppoedly siilar dB rating as the "quiet" dewalts, but the price and size of the thing is kinda unweildly to live in my basement the shop vac will fit under the table in comparison.

The rona on my way home doesn't have it listed as in stock but there is a lowes not too far out of the way that lists some as in stock. The shop vac was honestly to the point where I was using hearing protection being downstairs, even after proping some plywood and leftover foam from other projects around it.
 
The Rona stores have the DVX12P model, which is not the Stealthsonic model which has the -QTA on the end of the model number. You have to go to a Lowe's or order one. I'd like a proper dust collector but I don't have room for both.
 
I almost have the lowrider 3 cnc back together but took a bit of a break to see if I couldn't get this moded/used ender 5 pro tuned in a little since i didnt feel like messing with a soldering iron tonight.

All metalhotend/direct instead of bowden tube so I tried to be a bit aggressive on the retraction (1.5mm & 35mm/s) and it was a bit stringy but it was getting close popped off the build plate Trying to bridge over the window.

what is the least expensive / most affordable 3D printer that works well enough to be used like a STEM project for a 9 year old?

just read about this one on AliE for $77 USD, but the fact it emits such a bad smell when used you have to vacate the room kills it as an option right now. my sil has severe MCS (multiple chemical sensitivity). I know MCS can be controversial as to whether it's real or imaginary, but I've seen what bad cologne a real estate agent was wearing once. he went to emerge for oxygen and morphine...or maybe it was adrenalin.

Stick to FDM printers with PLA filament for the least obvious fumes. ABS filaments require venting, and I'm pretty sure resin (different type of printer) fumes are toxic.
 
In my experience, the cheaper the printer the more time you will have to spend fiddling with it and adjusting it to make it work properly. Which it will do for 4-5 prints then something will go wrong. Watch local FB marketplace or CL for a used one like an Ender 3, and ask them to do a "Benchy" (standard test print https://www.thingiverse.com/thing:763622 ). You don't have to wait for it to complete, just make sure it's laying down the first couple of layers properly.
 
Atleast the resin printer is working flawlessly since getting it back from the warranty repair.

The ender 5 I almost have dialed in. Still having some bridging issues which look to either be improvements needed in cooling or me having the tip too hot. Reduced the retraction all the way to 0.3mm @35mm/s helped a lot with the stringing.

CNC I still need to take the motherboard out, solder 2 resistors and put it back in then it is ready to go.

Aquila (ender 3 clone)... might try to sell it liking the ender 5 design a lot better.

being where I live, that's a not going to happen. I am far to remote for anything like this to ever come up for sale...and I've been watching for 6 years now. :(

Started making one of these and an enclosure for the resin printer, suddenly having adhesion issues trying to print it on the ender 5 though when I didn't really change anything. The enscloure with have an outside vent but i'm planning to only vent outside near the end of a print not for the whole duration. Mainly to air it out before opening it.
