Greetings from Indiana! I am a long-time lurker of this thread in particular, it has been so helpful! Thank you all (Benedikt in particular) for your great work on this controller!

With that said, I do have a few questions I hope someone can help with, I am using this controller with a custom built X-Carve.
1) chriscnc mentioned something about a new factory firmware version, 2017-03-04-87NOR Does anyone have a link to where I could download this from?
2) I've got my unit configured to use inches instead of mm, but this poses a problem: my Z-axis requires 24000 steps-per-inch because I'm using a Gecko G540, which by default has 10x microstepping. My machine jogs in manual mode fine, but when running under a program, I have inconsistent depth issues with the Z axis, due to this setting being far higher than the max of 10000. I thought I could fix this issue by changing to mm, but while that fixes the Z axis issue, it creates the same issue on the X & Y axis, as they're belt driven, and the steps-per-mm comes out to 33.33, which is way lower than the minimum of 100. The controller literally won't let you input anything less than 50. Any suggestions here? If I can't disable microstepping on 1 axis of the G540, I may have to get a different stepper controller for Z.
Thanks for any input!
