Camera joggle cause nozzle lift

[Pavlin Stoyanoff]

Greetings! I have a small issue here. When I work with the machine everything is fine, but when I try to joggle the camera -> Move camera to position of the selected nozzle or vice vesa, the openpnp software sends command for lifting the nozzle to possition 0 and then it moves the head. How can I prevent lifting the nozzle? How to stop the first command?

Thanks!

I think that is the move to safe Z feature. If you check your log you can verify that. It will have some entries that say "move to safe Z", then you will see it send the command.

There is no way to disable it. I did at one time have some custom build that removed it, but that was back in V1.

Bert is right. No way to disable.

However, in the new motion regime I'm developing there will be virtual C and Z axes mapped to the camera, so even though it cannot move in Z it will remember the Z. So when you toggle back from the Camera to the Nozzle, the Nozzle will go back down in Z to the original location you had before. This way it will be both safe and repeatable.

Discussion here (it's a bit confounded in other issues):
