LinuxCNC homing twice in Axis SImulation

I'm having trouble understanding why my "axis" simulation is getting "Cannot home while shared home switch is closed". This happens once I click "Home All" twice. I'm wondering if I have something setup incorrectly.

My end goal is to be able to do this via python. I have attached my current python code (which I don't think is the issue) and I get the same issue.

Thanks

Simulated switches so you have to move all axis to be able to home again.

Thanks for your reply tommylight. Sorry if this sounds stupid but I selected each axis (X, Y, Z) and click the +/- buttons to move it in that direction, but it still doesn't seem like Home All works. It only seems to home the y axis (so j = 1).

Im still getting errors for j = 0 and j = 2

I do recall getting the same thing sometimes, but i never really bothered with why it happens, it is a sim and i use it only to check the gcode sometimes, not for anything important.
If you want to test on a real machine but with no machine attached, use the parallel port configs, so will work even with no parallel port, but it is a real machine so nothing is simulated. You will have to use immediate homing for it though.

I think what you experienced is expected behaviour. Once an axis is homed, it can't be homed again unless its unhomed. I did notice recently in a axis sim that the unhomed menu was not enabled...
