TOMO M4, 4×18650 Power Bank – fail!

I bought from China, quite neat looking powerbank on up to four 18650 cells. It has all the needed features (almost) and even more – what could go wrong?

It has:

  • Output Overcurrent Protection
  • Input Overvoltage Protection
  • Electro-Static Discharge Protection
  • Overheat Safety Protection
  • Output Overvoltage Protection
  • Battery Overcurrent Protection
  • Input Overcurrent Protection
  • Prevent Current Reverse

Nice! It can charge and discharge each cell individually, has two USB output ports with 1A and 2A output current.

You can read many other nice things about this powerbank on Internet. But the big problem is, it’s a crap! Why?

Infitary 3d printer HBi3 (aka old M508) – new Marlin firmware and settings

New Infitary main board HBi3 vs M508

So, after a year of using mention printer it’s high time to do some firmware tweaking (despite all additional, already printed goodies for the printer itself). My Infitary set came with SD card, on which came also Marlin firmware source code for this printer. Because of it, we have, let’s say „configured” firmware. It’s too old to use now, but all we really need is Configuration.h and Configuration_adv.h files.

Now just a quick info. It looks like Infitary came with slightly newer version of the printer, it’s now called M508. The main difference is in the board – it looks nicer, is more colourful and it is also Ramp 1.4 now. In git repository of Marlin we cane find config files for this printer – but they will not work out of the box for my older model. I’m not sure, if it’s a proper name, but let’s call it (like in the auction I bought it) Infitary HBi3 (Prusa). The other visible thing, that has change, is the case for power supply.
