SCARA-3D virtual animation

Hello everyone. I had a problem using virtual SCARA animation. I'd like someone to give me advice or some information.
My goal is to use SCARA to draw the same model as the trajectory。



target

==============================================================================

The final "tk"


============================================================================
=============================================================================
What I got was different from what I wanted.。

QUESTIONS：At first the tool was too far from the trajectory.

I want to know how to adjust the position of the trajectory.

I want to know how to adjust the position of the virtual SCARA3d animation

Thanks

you shoudt update to the 2.9 master there is a better way to get vismach to work
and there is a complete new scara traj

Thanks . I have one more question. I use "net" to connect the motor to the axis of 3D animation. Do you know where there are tutorials? I feel like I'm linked, but I can't be sure.

Do you understand the meaning of this sentence, "net j0 axis.0.joint-pos-fb scaragui.joint0"?

In my opinion, "axis.0.joint-pos-fb = > J0 = > scaragui.joint0". Do you think that's right?

I didn't find such a description in the LinuxCNC documentation, all the links with "= >, < ="

look the picture

scara_sim_4.hal file

This section describes it very well.

Thank you. I've already read this file.

<optional arrow> is the bit you seem to be missing.

Really? I'll read the document again.

thanks my friend.

Nothing to read.

The arrows are optional.

Hello everyone.
Until now, I haven't figured out how to use the 3D virtual module to draw the correct pattern.
I have learned about "world coordinates", "tool coordinates" and "basic coordinates" these days. I guess I need to modify the world coordinates and the basic coordinates. Who can give me some advice, please?
