Extruder impacting Bed at Startup

What is the problem?

I recently updated a DaVinci 1.0 with Repetier 0.92 firmware to enable OctoPrint and 3rd party filament. Firmware update was successful. File was sliced with Simplify3D version 2.2.2 and uploaded to Octoprint. Upon startup the bed was raised to the max height. The extruder started to move and hit the bed while trying to adjust X and Y positions. Very loud impact and I hope the printer isn't damaged.

To troubleshoot I updated the Slicer to Simplify3D version 4.1.2 and ran into the same error. This print was my first attempt with the Repetier firmware and Octoprint.

Any suggestions would be greatly appreciated. Thanks,

What did you already try to solve it?

updated to most current version of Simplify3D 4.1.2. Also tried to connect directly with Simplify 3D to isolate problem and was unable to print via direct connect with Simplify 3D as well.

I am using a XYZ DaVinci 1.0 updated with Repetier firmware version 0.92 and simplify3D version 4.1.2

I was able to correct for this by measuring the Z - Zero point using the "MAINTENANCE/Zmin evaluation" This measured / established the 0 position on the Z axis. All is well and executing my first Octoprint trial as I type this. Great system, thank you!
