[machine pos topic is not updating] #120

Open wildanxgifari opened 1 year ago

Hi Flynn!

I enjoy your work very much, I use it to control my delta printer via joystick

I want to get feedback for the robot position however echoing from /cnc_id/machine_position does not output anything

What may cause it to happen?

Thx, Wildan

Thank you for creating your first issue on this repo! Give me some time to review and respond to your problem.

Hey @wildanxgifari! Glad you enjoy this package. I'm traveling right now but will look into your issue when I can soon.

flynneva commented 1 year ago

@wildanxgifari so this repo I believe uses actions, which feedback on the current position should be sent back to the action caller.

Let me double check that it's functional on my bench and get back to you.

I get the position display when I use ros2 topic echo /cnc_001/machine_position in meters. x-45mm Y45mm x: -0.045m y: 0.045m
