Hi everyone,

So I just got myself a serial port pcie card and connected it to one of my EM806 to see what the protuner software offers. I'm glad it finally worked after million tries with a usb-serial cable but now I'm not sure how to properly tune everything and how to select the microstep and current. should the current be the same as indicated in zappautomation site? I'm supplying around 60v so I think it should be 4.3A as per the stepper motor page but I'm not sure. there is a guide for resonance as well but I didn't go through with it yet.

and btw should I wait until I finish my build and actually connect the motors to mechanical parts before doing any tuning?
