I wanted to change my Infitary HiB3 stepstick drivers with TMC2130, mostly to get it working more quietly but also because the perspective (meaby someday…) of other nice features of Prusa i3 MK3 where appealing. Sadly Infitary has all motor drivers SMD soldered so I had to get everything new. I ordered (what seems to be the best value-money choice) Chinese MKS 1.4 board and pack of 5 TMC2130 v1.1 stepper drivers. The only difference (except the price ;)) between Chinese 1.0 and 1.1 TMC stepsticks is that 1.0 are soldered to be used without SPI feedback data. You could change them manually from 1.0 to 1.1 (you would need to resolder 3 jumpers and change side of 4 connectors – see picture), but I assumed it’s too much hassle and I went with 1.1 directly Continue Reading
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.
