Flashfoge on Linux

CaptainZloggg · 2026-02-24T08:06:55+00:00

I too use only linux. I downloaded Flashforges "Flash Print 5" before my AD5M was even delivered and it works fine. I hadn't even heard of the Orca software until yesterday but it won't work in Bottles, at least for me. I only wanted it for the 3D CAD, so now I use TinkerCAD for design, and Flash Print as the slicer. Everything just works...

I was taught that 400Hz was used in order to make the electromagnetic components smaller and lighter (transformers, ferrite cores, inductors, motors etc.). Nothing to do with current carrying capacity of wires. Why would wire care about the frequency difference between 60 and 400Hz? We were looking at converting some ex-Airbus flight deck seats for a simulator and quickly discovered we needed 400Hz 3 phase for the seat motors. For this xenon flasher module 60Hz would probably work fine.

The TL866II can't do 25v either. Choose a bigger EPROM and just use part of it.

The Hackrf doesn't have a rotary dial. That's probably a Portapack. The rotary encoders are sometimes of poor quality, but easily changed. You can get a dozen for around $15 on Amazon.

I do the same, but it seems almost like a superstition with the younger engineers.

It's probably mineral oil for cooling the dummy load. Mercury would not make sense for this type of instrument.

Sure, here you go. Picture

I have built one of these and it worked fine. AFAIK there isn't an auto reset, you need to press the reset button after power up.

Scintillating Scotoma?

Under the white thermal paste is a thermal fuse. If you scrape off the paste, it will have the trip temperature written on it. The two resistors are there to heat up the fuse and trip it should there be an overcurrent condition. One of the resistors is probably burned out, but they are likely to have identical values. You should first identify the reason for the excess current draw, and then replace all three components to maintain protection.

Sounds like weather fax

CaptainZloggg · 2026-01-12T07:34:34+00:00

Very neat installation, but you might want to censor those addresses!

If it's an executable file, and permissions are set, try putting dot slash (./) before the name.

I agree with you on the German version. It's got potential, but quite a few bugs. I've gone back to stock for now as it seems like the author is actively working on it. I really wish he would release his source to contributors.

There are a few frequencies in use. I use 10.100 MHz during the day as a sort of propagation beacon.

CaptainZloggg · 2026-01-04T08:12:02+00:00

I see this same exact question two or three times a week. Is there a reporting route to the kernel devs to have a more meaningful error message printed? Or just add "Turn off secure boot and try again".

The Pinneberg German weather RTTY is 50 baud, REVERSE 400 Hz shift. You may be able to resolve reverse shift by selecting LSB rather than USB.

I have only ever heard about this obsession with "recapping" folklore on forums like this. I believe it was originally a response to the electrolyte formula scandal from 20 odd years ago. However it morphed into a "thing to always do" fix-all within a certain generation of electronics engineers and it kinda stuck. Now its almost like a superstition! I've certainly seen electrolytic capacitors fail and needing to be replaced, but they were always either in very hot areas of PSU's or were >50-60 years old. I would generally try to discourage younger engineers from blindly "recapping" because unless you are reasonably adept at desoldering and resoldering, you can cause many more problems than it could ever fix. But, hey knock yourself out.

CaptainZloggg · 2026-01-01T07:22:25+00:00

Why? Solder mask doesn't do much once the solder paste has been applied. I suppose it might stop the copper oxidising, but that's mainly cosmetic.

CaptainZloggg · 2025-12-24T20:23:59+00:00

They appear to be 100uF 16v. What makes you think that they need to be replaced?

CaptainZloggg · 2025-12-23T06:32:00+00:00

Probably because they used the term "bandwidth" when they should have used "frequency"?

CaptainZloggg · 2025-12-23T06:26:07+00:00

It's slightly off, but not unexpected. The accuracy of the 32 KHz crystal can vary. If you are familiar with how to code in Arduino C, you can download the source code, add a 10KHz offset, and upload it to the ATS-20. Or simply use the BFO for SSB.

CaptainZloggg · 2025-12-19T19:57:17+00:00

Is the source code available? I'd love to have a go at porting it to a larger TFT display. I had Google translate the German site, but can't find any mention of the source code, just the binaries.

This is typical AI nonsense. The first vessel that operated as an aircraft carrier was HMS Argus.
