Linking two gantry joints with homing switches so it unracks on home

Any thoughts on the Following Error if the jogwheel is still active when you hit a button that invokes a g-code command? That's a red flag blocking the conversion.

No. In fact it has me very puzzled as it should wait until it is out of manual mode before running G-code. 

 

Hi, sorry I asked that question before in an other thread;
But this gantry problem seems to be more to the point;
@rodw  you said earlier:
But as an aside I don't really understand why we have to home a joint axis before it can be jogged. Linuxcnc knows which joints are tied together, why can't a jog request of a single unhomed joint jog its mate?

If Lcnc knows, then from where and how could I get that information out of Lcnc?
How can I find out which joint/axis is mapped to whom?

sorry again and thanks.
