Funny story. I bought a printer for my kids this year. An Anycubic Mega Zero with a magnetic base. It stays pretty calibrated but I have struggled with base adhesion once a few prints have been through it. IPA and abrasives have not fixed it...maybe I will get around to some other things...there have been a few random failures, but not many. We printed a few novelties items that came out OK. The real learning curve i…

Have you tried covering the build plate with a glue stick? Always worked for me, at least for PLA.

> FYI a 3D printer is super affordable nowadays This seriously cannot be understated enough. When I was in my final year of high school (2012) my shop teacher was the first person in the entire school board to get a 3D printer, one of the cheapest machines on the market (I can't remember the brand, or the name, only the number at the bottom of the invoice - $11,374.38). He got the machine in February and tasked me to…

>When I bought an Ender 3 V2 around November This is 100% my recommendation for a first time 3D printer. I bought a wanhou i3 about 4 years ago and it was endless frustration. The Ender 2 V2 has been a completely different experience. I have probably 200 hrs of prints through it and just a handful of relatively minor issues. I did have trouble with Octoprint however. I stopped tinkering pretty quickly but IIRC there…

I switched my printers over to Klipper and have been overjoyed with the change.

It’s a different style of firmware where all the gcode interpretation and motion calculations are done on the more powerful raspberry pi* and only the motion control pulse generation is done on the printer’s board.

You get very precise step control as a result and with no start-stop blobbing within a layer.

If you don’t want to go that far, look into max resolution settings in your slicer** to reduce tiny moves which might be overrunning the printer’s ability to process. Note that this is still useful with Klipper as well.

* I’m using zero-w Pi, which is still way more powerful than a printer board.

Nice! thank you!

I have heard of this and it is on my list of things to try. It seems counterintuitive to me that the glue wouldn't simply become a runny mess. Thank you for confirming it works. Just confirming we are talking about 'Pritt-Stick' when people say glue stick, are we?

is that a normal experience in all of the US or only certain states? sounds all kinds of fucked up. the random passerby ratting you out. cops showing up over a handgun, which as far as I know are legal to own in all states unless you're a felon. doesn't sound like land of the free at all.

Yep, that's what I've used with success as well

I got a 3D printer earlier this year for no other reason that it was on sale. I cannot even begin to describe how much fun I've been having with it. Funny enough, I've had to print some of the things on the list. I have a pile of ~10 keyboard legs right next to me on the shelf, they often take a hit when I'm angry at something.

Years ago I owned and worked with tons of different FDM printers. They were always needing a height calibration or nozzle unclogging or something else. Does yours seem to work reliably? Honestly I got to the point where I just thought FDM would never be a reliable tech but I would love it if I was wrong. If yours is reliable, can you tell me what brand it is?

Just get a Prusa, they're so good and reliable and the quality is amazing. You can either buy it in pieces (takes about 8 hours to assemble) or pay a bit more and buy it already assembled. I've had a couple of Ender 3's and they start out great but end up deteriorating in print quality after a while so you have to keep tweaking stuff which can be an exercise in frustration. Just my experience.

Don't think op is in US. Nobody would say "phone engineer" in the states.

I love 3d printing, but I really desire to have the ability to print metals. As a simple dij solution not feasible at this point. I really wish to print replacement parts for my old exotic cars. Bearings, wishbones etc

Suspension parts may be a bit much, but I've had good success with smaller parts for my race bike. Like brackets for a CO2 regulator that would have been difficult in metal due to angles necessitated by the curve of the fender. http://www.daves-speedshop.com/CO2brackets.php Making my own velocity stacks for the throttle bodies allowed me to add mounts for a sensor and the airbox tray. http://www.daves-speedshop.com/graphics/FT550/sparkPro2.jpg I couldn't make those out of metal without a full CNC mill.

I use elmers glue sticks (the purple ones which dry clear), but Pritt should work as well. It's slightly messy, especially since the purple color comes back if you wet the surface. Then again, this helps to make sure you got all of it off. The underside of the print is slightly tacky, but nothing a wet paper towel can't fix.
