elucubra@sopuli.xyzto 3DPrinting@lemmy.world•good results so far with Elegoo Rapid PETGEnglish2·6 days agoI really like elegoo rpetg. It really likes moisture, though. Not a problem for me with my redneck dryer, though.
I’ll be making a video with my setup soon.
I had a bunch of rolls of plain petg, and dumped them on a second hand market. Never looking back.
Also, Sunlu PLA+ 2.0. Great PLA.
I want to try Polymaker HT-PLA-GF. High temp resistance (150°C) right off the printer, more if annealed, and glass fiber. Should be a great replacement for many engineering filaments, but printable on vanilla printers without enclosure/filters.

It works wonderfully for some, a not at all for others. I have worked a lot with epoxy and plastics are always a “try somewhere else in the part” thing. Also, if there is grease on the part" forget it. Even with epoxy especially formulated for plastics.
If all you want is to use the epoxy as a filler, it may work.
I have searched aliexpress, and there are kits for around 17€. I don’t know what the shipping and customs are where you live.

elucubra@sopuli.xyzto Technology@lemmy.world•How to Get Hardware Transcoding BACK on Your Synology NASEnglish1·15 days agoGamer desktops tend to be power hogs. Running them 24/7 can rack up some hefty power bills, plus noise, plus space, plus other tradeoffs.
Better a used thin client.
elucubra@sopuli.xyzto Technology@lemmy.world•How to Get Hardware Transcoding BACK on Your Synology NASEnglish1·15 days agoIf you have a 3d printer, or access, o know someone willing to print for you, there are many free models out there
elucubra@sopuli.xyzto Technology@lemmy.world•How to Get Hardware Transcoding BACK on Your Synology NASEnglish1·15 days agoDefinitely an option, but for the price of a Pi with all the extras, case, power supply, etc, you can get a used thin client that is way more capable.
There is a guy on YouTube that often reviews these things, and discovers some models that are surprisingly capable.
elucubra@sopuli.xyzto Technology@lemmy.world•How to Get Hardware Transcoding BACK on Your Synology NASEnglish4·15 days agoSynology publishes a list of certified non-synology drives, and warns you that drives outside the list are not recommended, but, at least in non enterprise models, allows them to be used. I believe there is some rather easy way (some config file change or the like) to circumvent the limitation, but yeah, dick move.

elucubra@sopuli.xyzto Technology@lemmy.world•Reddit stock falls for second day as references to its content in ChatGPT responses plummetEnglish10·15 days agoTesla sells itself as a technology innovation company, but it sells hype.
Is that compatible with other brands? I believe most MMUs are only compatible with their own printers. That’s another advantage of INDX, and other toolchangers I’m sure are in the pipeline. I’m going to be installing an INDX in my heavily modded Ender 5 Plus, and if I ever decide to sell it, or retire it, I know I’ll probably be able to carry it over to another printer.

The question is: that thing is a tethered balloon. If they expect to have it float 10 Km up, it has to be tethered with a cable at least 10Km long, which should be able to withstand the forces created by wind resistance, plus its own weight, and be conductive, so some lightweight cable won’t cut it, metal will have to be involved, and not some lightweight signal cable, but hefty metal. Will that thing be buoyant enough to lift that cable?
elucubra@sopuli.xyzto Technology@lemmy.world•'Windmill': China tests world’s first megawatt-level airship to capture high windsEnglish2·22 days agoIs that thing going to be able to float itself and support the weight of the cables at the altitudes they talk about?
I may agree in a DIY setting, but for a business it’s a sunken cost fallacy. I’ve owned 2 businesses where productive equipment were integral. Replacing machinery where there is a substantial improvement does make absolute business sense. Also, if you allow a machine to wear out you are shooting yourself in the foot. It’s much better to unload them in the second hand market, and renew. I haven’t owned a print farm, but I’m certain that amortization is fairly quick.
The industrial ones may be tough, but the one in the video looks janky and the abundance of printed parts does not inspire confidence in its longevity. Also, it is an addon to an MMU, making the whole multi color set up closer to $500, and limited to bowden, which precludes flexibles. Once a tool has been swapped it must be heated to the proper temp for the filament.
I’m not intimately knowledgeable with subtractive CNC, but I own and have used a lot a hand router, so I’m familiar with the business end of the things. Reliability is not going to be the same with a dry tool or toolhead, than with an oozy nozzle.
The system is for bedslingers only, which are inferior to cartesian or CoreXY cube printers.
The INDX is way more capable, simpler (thus likely more reliable) made by Bondtech, which has a proven reliability and performance record.
The only scenario where I see this being equal or superior to a toolhead changer is, well, none.
If you have a print with supports, having a support filament that adds little extra time, compared to an MMU, is much more than nice. Being able to use rigid and flexible prints reliably in the same print is more than nice. From what I have read, flexibles in MMUs are prone to failure.
The swapper may reduce poop, but it looks like it won’t reduce print times.
Also, it looks like it has a ton of failure points. Tool changers are much simpler and faster.
Most MMUs are in the 300€ range. For that money you’ll soon be able to buy an INDX tool changer from Bondtech.
No Brainer.
Wild guess here:
Maybe your hotend thermistor is failing, but not dead, cutting out intermittently, which could cause the hot end temperature to be fluctuating, thus alternatively under or over extruding.
To see if your filament is humid, raise your Z, and with a magnifying glass look closely at the extruded stream while you extrude. If wet it will be uneven and/or have bubbles.
elucubra@sopuli.xyzto 3DPrinting@lemmy.world•Is there no good inexpensive CAD software?English2·25 days agoThat’s my take too. Also, while pre 1.0 development was kind of slow, it looks like it’s picking up speed. I guess releasing 1.0 may have given it much needed visibility, and probably attracted some developers.
I’m thinking torque rather than speed. I have converted an Ender 5 Plus to Hybrid core Y, with the Endorphin mod and I’m mulling adding an extra stepper on the X, and increasing power on the Y, either with a larger Y dual shaft or adding an extra stepper on the Y in series.
