I’m trying to get a Arduino CNC (cnc shield v4 with arduino nano) shield to work properly. But it seems that the shield has the MSx jumper pin connected to ground. This basically is useless since it seems that by default MSx pins are set to low, and need to be set to high to activate. I can make the micro steps work when i directly connect the driver to a breadboard and set the MSx pins to high.
My question is, can the MSx pins be changed to have default high ? this seems the be what the shield seems to be expecting. I read here and there on the web people stating that A4988 are normally high on MSx pins, but when i try it’s not the case ?
