I have the Makerfam 8 inch I put ABL together and reloaded the firmware to the latest Marlin software. I followed ZennmasterM instructions and also loaded the firmware following his YouTube video on this subject. I got the servo to work correctly. I tested the micro switch to make sure it was triggering. I then moved to the steps to set the probe offset and I found that the Z axis (when I tried lowering it in Pnterface) turns the Z motors VERY VERY slowly. You can pretty much count the steps. The X and Y work fine.

Can anyone shed some light on correcting this. My guess (and I could be dead wrong) is that is is software related becuse it worked fine before I updated the firmware (the Z axix I mean). I just have no dea where to look.

Your advice is appreciated. Thank you
Bill
