i bought a plastic scribbler, it was my second 3d printer purchase, first arduino. the drv8225, one of them were malfunctioning, screwing up my prints. plastic scribbler just sent me a new ramps and arduino board, thinking that solved the issue. i am still confident the stepper motor driver were the culrpit.
anyway, i purchase the stepper motor driver, realized it was a a4998, after waiting almost two months from china, i finally got it; to only realize its not responding @ all.
now, i've read that you can use the a4988 into these ramps, but i don't know if i have to remove all of the drv8825 with the a4988, also read that plug it the wrong way and you can screw it up. SO.....
the question is, how do i make the a4988 compatible with my ramps how do i install it the right way, if i can make it compatible.
don't want to purchase the drv8825 and wait another month. i'm losing my mind without my bigger printer, which is down.
