Looking for a proper firmware for my prusa i3

I have a prusa i3 based printer, it's specs are these:

Arduino mega 2560
Ramps 1.4
Lead screw for Z-Axis (8mm diameter with 2mm pitch i think(I measured distance between two threads and it was 2mm)
Nema 17 stepper motors
MK8 compact extruder
And 2004 LCD with onboard SD card slot

I tested the marlin firmware that the vendor gave me (it's here [uploadfiles.io]) but it has a problem in Y-Axis and I couldn't solve that(when I push Y+ or Y- in pronterface it acts weird different in any time ...goes forward, back, etc) ! Also extruder doesn't work. Also D08 and D09 doesn't work (I connected heatbed to D08 and extra cooler fan for ramps board to d09 but they don't work! only D10 works)

I am loocking for a good firmware

issue with Y axis is probably hardware, not enough current going to steppers (ie you have adjusted your vref)

I suspect same issue with your extruder...

D8 will only work if you have power on the 12v 11amp circuit
D9 should work... could be firmware, could be dead mosfet on ramps, could be you plugged the fan in backwards



test your ramps with the ramps test firmware [reprap.org]
NB it makes all motors move back and forwards ignoring endstops and turns the mosfets on and off, so if you have heaters attached it will get hot.

I would check the y-axis motor wiring pairs with a multi-meter.
[reprap.org]

Make sure the A pairs are next to each other on the ramps pins (same for B pairs)

Thanks guys. I solved the problems (by socketing again the connectors)

The only problem that remained is D09 and D08 pins that they dont work! so I have not heated bed!!!
