So I have purchased a RE-ARM board for my 3D printer. I want to use SPI Mode with TMC2130 Stepper Drivers and a LCD Screen. I have seen that there is an issue with conflicting pin usage on AUX3 of the RAMPS board for these two technologies. Because of this, I found that the Viki 2 LCD is actually able to be attached to the RE-ARM directly on it’s J3 and J5 headers instead of using the RAMPS board’s AUX4 pins and AUX3 pins. The question I have is that the RE-ARM looks to primarily be a Smoothieware Board but can be used with Marlin. I would prefer to use Marlin on this device. Are the J3 and J5 Headers that are directly on the RE-ARM board still accessible through the Marlin Firmware and allow the Viki 2 LCD Screen to work on them? Or is the functionality of these headers with the Viki 2 LCD only a feature with Smoothieware? I would rather not perform too many configuration changes to the pin outs of the AUX Headers and Servo Headers of the RAMPS board and being able to use the RE-ARM’s J3 and J5 headers would save alot of time and headache.
EDIT: I also need to attain information on how the Jumpers under the Stepper Drivers should be set for a RAMPS 1.6 Plus. It has a much more complicated Jumper setup. 4 sets of 3 pins and you can either remove the jumper or set it to bridge the left 2 pins or the right 2 pins. I have been unable to locate documentation on these Jumpers for SPI setups
