Re: New build what controller to use? - 11 years ago
I really hate to waiste my time and answer the original question, but : I like the Megatronics solution because 1. it combines the Arduino and Ramps into 1 compact board 2. you can use the 1/32 drivers (though, at first I was confused about how many jumpers to use)by Fitz - Reprappers
Re: Jumpers for DRV8825 on Megatronics 2 - 11 years ago
Thank you for your responce george4657. I missed the visible difference between the old and new versions. I do indeed have the newer model. The board does as described with 3 jumpers when using the Megatronics test firmware. I'm on to trying to figure out Marlin firmware configuation. Tanks again.by Fitz - Controllers
Jumpers for DRV8825 on Megatronics 2 - 11 years ago
I'm trying to build a 3D printer using a Megatronics 2 controller. I got Pololu DRV8825 stepper motor drivers for the 1/32 steps. My problem is the Megatronics 2 wiki. In one place it says that each DRV8825 needs to use all 4 of 4 pin jumpers and 2 sentences later it say "Pololu has released an updated version of the DRV8825, that doesn't need the fourth jumper". Does anyone know how I tell iby Fitz - Controllers
