@droftarts Well it will definitely be one of my first places to check from now on XD

Its funny how easy it is to overlook that, that seems to fix the issue for now as my u axis is now homing correctly. I guess this goes to show what happens when your creating config files super late at night lol.

Thank you very much @droftarts

Cheers

I am trying to set up my machine with independent lifting tools. At first I could not home any axis as I would keep receiving and insufficient axis homed error, which I found ironic, which I fixed by adding M564 H0 to the config file. now my x and y axis home just fine but I cannot home the u or v axis as it ignores G1 H1 and G1 H3 commands and only executes G1 H2 commands.

Here are my config.g and homeu.g files. hopefully you guys can see where i went wrong.
