Hi recently I bought a second Ramps 1.6 (ramps 1.4 with mosfets and stuff) to have a spare and oh boy did I bought it right in time. My last board (same as the new one) shorted out while trying to figure out the vref on DRV8825 drivers.
I changed the board, drivers (it fried two of my TMC2130 drivers), cables all just not the extruder motor. On this new board I cant get 1/8 stepping and idk why. I checked the board for solders and it looks OK. I removed the MS3 jumper, even tried different jumpers but it seems like I still get some incorrect stepping.
Previously, before shorting out the first board my settings were: 1/8 stepping, 1900 steps and it worked perfectly.
Now i get horrible under extrusion which seems to be the problem of wrongly used microsteps. I have set the stepping to 1/4 and 1900 steps and it still underextrudes by about 10-15%.
Can anybody tell me what the hell is going on ? Both of the boards are clones ...
