You're going to get mixed advice from the people here. However, I'd offer this: I agree with getting the Ender 3 to learn the ropes. There's a massive community of Ender 3 owners out there, including printable mods etc. 1. Whatever printer you buy, DO NOT commence with modifying the printer until you've learned how to print well with the machine and have learned it's strengths and weaknessesby obelisk79 - General
Why do you say ABS is MUCH better than PETG? Tensile strength is similar between the two materials. Carbon fiber PETG regains most of the tensile strength difference compared to PLA. ABS has better impact resistance, but 3d printers shouldn't experience a lot of impacts. Is the recommendation based on melting temps regarding operation inside a heated enclosure?by obelisk79 - General
I've been using the same x carriage made of PLA for two years without issue. If you are going to use a heated chamber, either figure out how to anneal it or use a different material like carbon fiber PETG. EDIT: Also, always keep a spare set of printed parts for your printer on-hand in case of any unexpected failures.by obelisk79 - General
I love it. It's an evolution of something other than the same regurgitated copies of copies of prusas, hypercubes and kossels. I also appreciate the concept of using the printer to make the printer better, which is a more common practice but you've certainly done a good looking job of it in my opinion. I assume it is working well for you. Thanks for sharing.by obelisk79 - Developers

Flex3drive is pretty much superior in every way. The nimble was always a copycat wannabe trying to leverage flex3drives design. The difference in recognition is due to marketing. I wouldn't pay more for an inferior product(aka Zesty Nimble).by obelisk79 - Reprappers

Annealing PLA is done at 60C: Ziplock bags are good up to 100C: foil would deform the surface of the print I still think a bad would be your best option.by obelisk79 - General
QuoteDust The potential issue is the sand may stick to the plastic... Not if you stick the part into a plastic zipper bag. Or vacuum bag. Then put into bowl and pack with wet sand to ensure more homogenous heating. I mean, in my minds eye I see this working pretty well.by obelisk79 - General
The sand idea may work. I would maybe place it into something like a ziplock bag to prevent the sand from texturing the part unless you find that a desirable possibility. I like Dust's suggestion too, but a fine sand would be easier to work with I'd be willing to bet.by obelisk79 - General
I'd only argue that the linear rail 'upgrade' was probably unnecessary. V-wheels really are an excellent linear motion system if assembled properly. You've done a lot to that printer, good stuff, and for what it's worth... Sometimes, I find doing things the hard way rather enjoyable and educational too.by obelisk79 - CoreXY Machines
Crude doesn't mean stupid. Just means simple or basic. Not basic like someone who obsesses over pumpkin spice lattes either.by obelisk79 - CoreXY Machines
QuoteMKSAAnd what do you consider a high tech, non rudimentary solution then ???? The unnecessary solutions people use like 2 and 3 motor bed leveling, mesh bed compensation, and quirky bed sensors like bltouch or piezo ones. Don't take my statements as implying that low-tech is a bad thing. Low tech means simpler, probably more reliable, and most certainly cheaper. But hey, like any other snakby obelisk79 - CoreXY Machines
QuoteMKSA If it is simple, it is not crude ! It is the smart way to do it ! CRUDE: constructed in a rudimentary way. Crude still fits. It's a functional, reliable low-tech solution which I use on my own printer.by obelisk79 - CoreXY Machines
If you anneal PLA it's temperature performance can exceed that of ABS. But there is a trade-off. The annealing process can warp your part. It also causes shrinkage that means you'd probably not want to go that route for anything requiring precise measurements. PETG is a more temperature tolerant material that is easier to print with an open printer although ABS is the better choice if you're ableby obelisk79 - Printing
If your bed isn't heated you can try using a piece of glass with some abs slurry. It's not the most ideal approach though.by obelisk79 - Printing
I think that may only be an issue with certain materials that have a tendency to stick to the nozzle such as PETG. But I'd be interested in getting feedback like you've mentioned. I recently watched an interesting test done by cnc kitchen on youtube regarding extrusion width: He also comments on impacts for quality/detail and you see illustrated the potential benefits of the extra surface areaby obelisk79 - Printing
I love the uv lighting you use. Are those led strips or something else. I drive my bed using two screws belted together with a single motor. It's low tech but I like the simplicity.by obelisk79 - CoreXY Machines
Couldn't you mechanically link up the two leadscrews with some belt and pulleys and get the same result? It's a bit crude but simple.by obelisk79 - CoreXY Machines
Suggestion? Look into Klipper firmware. Marlin is just clunky to work with and requires a reflash every time you need to modify a configuration and based on what you've said so far sounds like you'll probably be tinkering with configurations a good bit to get your custom Prusa style printer dialed in. 'Most' people who try it out notice an immediate improvement in their print quality. This isby obelisk79 - Extruded Aluminum Frames
I'm curious, what would be the benefit of using an airbrush nozzle over the e3D nozzle form-factor.by obelisk79 - Printing
I admitted in my response that the Maestro would work well. But in a simple 4 motor printer the benefit really comes from the software and not the hardware of the board itself. Like we discussed in the other thread where I brought up Klipper, it also allows for-on-the fly configuration changes. I seriously dislike firmwares like Marlin if for no other reason than the requirement to reflash to makby obelisk79 - CoreXY Machines
I mean your answer is to toss in a $130 controller into a $300 printer? You can get outstanding, reliable results with any widely available board. Then use Klipper, RepRapFirmware (its been ported to at least the LPC series architecture) or Marlin to get out of the closed source malarkey TronXY is pulling. Hey, it's your cash, the Maestro will certainly do the job and it should at that price buby obelisk79 - CoreXY Machines
So with Klipper, your Raspberry Pi connects directly to the host board via USB, so network related communication problems with the printer controller should be non-existent. I know I certainly don't have any. I do on occasion notice that I have to refresh Octoprint while monitoring it remotely. I'm not sure if that is a RPi issue or Octoprint Issue. If you find that Octoprint itself isn't yourby obelisk79 - Extruded Aluminum Frames

I think the choice of driver is a critical factor in managing heat with pololu style plug-in drivers. I can't think of one that will operate near full current with passive cooling. However with a heatsink and lower flow silent fan heat is never an issue with the setup I'm running. If you oversize your driver compared to max motor current you'd see heat be more manageable without active air flow.by obelisk79 - Extruded Aluminum Frames
I'm a budget/value kind of guy. There are some great arguments in favor of going with Duet. It's a high quality product with good firmware. That said, I prefer to use Klipper firmware and currently have it paired with an inexpensive Raspberry Pi 3B+ and inexpensive 32bit SKR board. It runs excellent, shares many of the same convenience features of Duet/RRF. UART configuration of TMC drivers,by obelisk79 - Extruded Aluminum Frames
