I’m setting up the lowrider v4. The z and y axis are not stopping when being homed. They hit the endstops, but the gantry continues to click and try to move. (The x axis is the only one working). I’ve checked the endstop wires in the control board, and the green lights are on when running. I’m using fluid nc on iPhone to run the tests.
Thanks for the help
Open the terminal in the webUI and run the command $SS.
The top few lines will show what firmware version, 3.9.9…etc.
it will also tell you what config is loaded, mpcnc or LR as well as what board version.
You can cut and paste it here or screenshot.
Double-check the endstops section for the jackpot1, here, Jackpot CNC Controller - V1 Engineering Documentation Most frequently missed is, they only actually work when homing, not just moving.
Usually the endstops are mixed up then, swapping one Y for one Z or something like that. 
Agreed, but of particluar note is the need to use $Limits command to check the endstop phasing.
The endstops being swapped between the two different dual axis steppers is a common problem.
We should be explicit about offering help rather than just saying “Read the instructions”
Exactly.
Sorry, I totally agree. I have already said to use $limits in an email and suggested it would be easier to post here so I can quickly link the instructions sections that show this. For future readers I should have reiterated the previous steps.
Thanks for all the advice. It ended up being a simple mistake. I had the wires labelled backwards when I first assembled the unit, z wires labelled for y, and y wires labelled for z, so the endstop wires were in the wrong place in control board. Thanks again
