Last night, I hooked up my MP3DP to power, steppers, and end stops. Using Octoprint (not an LCD which I have not hooked up yet), it moves, but not properly, and suspect the problem is firmware related. I ordered all the parts from V1Engineering the beginning of October last year (2018). It is a completely standard, no mods, no double end stops. The controller board is the Mini-Rambo. The hot end is the MK8 with the Swiss throat and nozzle. Reading the forums, posts from September 30, 2019 indicate that Ryan has created new versions of the firmware, but the GitHub repo hasn’t been updated in 8 months (which is still newer than would be on the Mini-Rambo). There is a preconfigured MP3DP version of the firmware, but for the Aero, not the MK8. Is it the same? Where is the new firmware to be found? I saw reference to Ryan creating a new repo in relation to some licensing issue. Also, is there a guide for updating a Mini-Rambo’s firmware, that you could recommend?
The MP3DP moves in the X, Y, and Z access, but only in one direction, away from the end stops. It thinks it is homed at 0, 0, 0.

The end stops are wired NC, but show all triggered. I tested the end stops with a multimeter before installing them. I used Ryan’s Mini-Rambo end stop connectors and while probably not critical, made sure the GND was connected correctly to the end stop connector.

It is probably something stupid. Any suggestions would be appreciated. Thank you.
