  1. Buck converters work on the basis of using an internal oscillator that generates a nominal 'high' voltage frequency, which, when then rectified & regulated, produces a steady state output voltage up to the nominal rated current output, (as long as the source can supply this current) but will drop off if this is exceeded. So by using one, you will at least guarantee that the output stays constant, but by the nature that it works, it may be 'noisier' with switching artefacts imposed on the voltage rail, which may then have knock on effects of the equipment being powered.
  2. For regulators to provide a reliable steady output voltage, you have to make sure that the source voltage is at least 3 volts above the nominal output voltage, to ensure the internal circuitry works correctly. So if your source power supply is below, at least 15v, I wouldn't bother, and may well provide an additional drain on the source, limiting 'running' time.

  4. How do you know its causing a short ?? An old DRY toothbrush, very lightly brushed in one direction only, if possible with a vacuum sucking off any debris....
  5. Personally, before I went down the hassle of the annealing route, I'd rather get it right in the first place i.e. properly slice & print the parts, e.g. 0.5mm layer height & 80-100% infill. Strength wise I doubt you would see much difference, maybe not as pretty, and with salt filling in the threads, as pointed out in the video, meaning more cleaning up to do....
  6. Do you have any drawings to at least give us an idea of what you are after ??
  7. One observation, levelling the mount tripod doesn't matter as long as you have good polar alignment, also is all you gear properly balanced ??
  8. Hi Sophie, 1st off, if you release the clutches on each axis, does everything move freely ?? 2nd, and If your mount is the same as mine, then you should have the ability to drive the mount manually using the elongated flexible controls (with the clutches engaged) ?? 3rd, with the clutches disengaged, can you drive the motors with no over loading\stiction etc. ?
  9. usually a fuzzy, not too bright blob, is ok..... Let PHD2 decide what it wants to use to guide on !!
  10. Personally I always go for Noctua fans, for long life, reliability, being quiet, efficient etc, e.g. https://www.amazon.co.uk/Noctua-NF-P12-redux-900-Ultra-Silent/dp/B07C5KZX85
  11. What makes you think that ?? if so it may be possible to repair....
  12. Tried that one, but it won't install, as the installer routine doesn't see the supported hardware, and immediately exits.
  13. I've installed the latest version for the HD 4400 Graphics hardware (20.19.15.5144), but still no joy for the 'basic' starter.
  14. I hate to say it, but just running the default 'starter' still doesn't work & just 'freezes' the computer, I have to use Task Manager to kill it. Using the "Stellarium (ANGLE Direct3D 11 mode)" works ok. Win 10 Pro v2004 via remote desktop. Logs.zip
  15. FYI, If you plug in the USB interface to different USB ports, then the COM port will also change....
