gantry mode issue

is there a way to lock y1 y2 before homing , so they can´t move individual and damage the machine in jog mode before homing? 

 

Short answer no, the system expects to be homed before jogging.
I've never had an issue with this requirement. I just power on and home all.

But this is Linuxcnc so anything is possible. 

In Axis 2.8.2-11 the UI will generate an error if you try to move joint 1 or 2 before homing.

Cannot jog joint n because joint is synchronized.

To test, set the increment to the smallest and try jogging joint 1 or 2.

Exactly.
PncConf generated config will not allow jogging of tandem axis before homing.

i run gmoccapy 3.1.3.8,  maybe there is a way to code it, a way where jog is disable when not homed

i just made a config of gmoccapy from PncConf, and i can still move y1 y2 unhomed 

Perhaps there is a bug in 3.1.3.8.

I just tried it with gmoccapy in 2.8.2-11 and I still cannot jog y1 or y2 before homing.
