U, V axes not working
-
I have added extra U and V axes to my delta printer on drivers 5&6 using Duex5. They worked several months ago, but a few things have changed, breaking functionality somewhere along the process. I had to redo my config file from scratch, so I am assuming part of the problem is just using G-codes out of order or something simple like that in my config file.
I think I might be missing something simple. The axes show up in DWC, they "home" properly using homeu.g and homev.g. I say home in quotes because the homing files are extremely rudimentary right now:
G92 U0 and G92 V0 respectively.
I can attempt to jog the axes using DWC, but they don't move, and the machine status never updates to show the position the axes should be in after the move command. There are no errors displayed. The drivers work fine, because I can swap the X, Y, and Z axes to run off of the expansion board.
Here is my current config file:

Try adding M208 upper and lower limits for U and V.

Yep that totally fixed it. I didn't realize those were needed. Fantastic! Thanks.
