I want to ask, I use Hal in glade_ In gremlin, when G code is used for control, is the trajectory presented the value fed back by the controller or the current trajectory planned by linuxcnc itself? Does anyone know?
Thank you

depends what version of linuxcnc and what value you are talking of.

master is better a reporting actual gcode that is currently running.

Hello, I am using Linux cnc2.8. What I want to ask is, when I am running my G code, is the track in the UI formed by the return value obtained from the controller?, I understand what you mean. You mean he doesn't get the real-time position track from the controller, do you? It's the G code currently running, isn't it?

您好,我使用的是 Linux cnc2.8。我想问的是,当我运行我的G代码时,UI中的轨迹是由控制器获取的返回值形成的吗?我明白你的意思。你的意思是他没有从控制器那里得到实时位置轨迹,是吗?这是当前运行的 G 代码,不是吗?

My English is not very good, please forgive me

The graphics 'track' is drawn by linuxcnc's understanding of current position.
Whether current position is also exactly the actual machine position depends on your hardware.

Closed loop hardware would mean it's a least with the following error width.

OK, thank you very much for your reply. I use a closed-loop hardware. Does that mean that the UI interface uses the value returned by the hardware
