Certainly! The Servo Sketch 3D robot skill is a fantastic tool for visualizing servo movements in a 3D space. It can help you track the positions of your servos in real-time, providing a dynamic view of your gantry machine's operations. Here's how you can use it:

Setting Up servo Sketch 3D

1. Add the Skill to Your Project:

   • Open your ARC project.
   • Go to the Project tab and click on Add Control.
   • Navigate to Graphs and select Servo Sketch 3D to add it to your project.

2. Configure the servo Ports:

   • Click on the gear icon of the Servo Sketch 3D skill to open the configuration menu.
   • Assign the servo ports for the X, Y, and Z axes:
     • X-axis: Assign to servo V1.
     • Y-axis: Assign to servo V60.
     • Z-axis: Assign to the servo controlling the up and down movement.

3. Adjust the Global Max servo Positions:

   • Ensure that the global max servo positions in ARC are set to accommodate the range of your servos (e.g., 130,000 for X-axis, 100,000 for Y-axis, and 140,000 for Z-axis).

4. Visualize the Movements:

   • As your machine operates, the Servo Sketch 3D skill will plot the positions of the servos in a 3D space.
   • You can rotate, zoom, and pan the 3D view to examine the movements closely.

5. Interactive Controls:

   • Rotate (Orbit): Left-click and drag to rotate the camera around the servo tracking area.
   • Pan: Right-click and drag to shift the view smoothly.
   • Zoom: Use the mouse wheel to zoom in and out.
   • Preset Views: Use control commands to switch to top, bottom, left, or right views.

6. Control Commands:

   • You can use control commands to interact with the skill programmatically. For example:
     • controlCommand("Servo Sketch 3D", "Clear") to clear the current scene.
     • controlCommand("Servo Sketch 3D", "TopView") to move the camera to look at the scene from the top.

Benefits

• Real-Time Visualization: See the servo positions in real-time, which helps in debugging and optimizing performance.
• Dynamic Trail Tracking: Visualize the path taken by the servos over time.
• User-Friendly Interaction: Intuitive controls make it easy to explore your robot's movements.

Feel free to experiment with the Servo Sketch 3D skill and let me know if you have any questions or need further assistance!

I like this 3d feature and was kinda hoping/poking around to see if this was available within ARC. Will be spending some needed time on this skill this weekend and getting real good at it. This has many beneficial attributes that I can already envision using. 3d compared to 2d now we're talkin, thanks.

I was trying to calibrate my gantry this morning

That’s not what the error means. Without seeing the code it’s impossible to diagnose

DJ is correct. That error message is not what you think it is. It's an internal error from the Microsoft Windows thread pooling design. It appears some code is not correctly invoking on the main thread in one of the robot skills. Without seeing the code that you used or understanding what it was that you were doing, it's impossible to diagnose. Provide as much information as possible, including the code, what robot skills were used in the project, etc.

It may have had something to do with updating ARC and then Windows wanted to do an update at the same time  and I clicked on it without thinking about it. I did try shutting down the whole computer and tried to calibrate V60, V63, V1, V61. For V60 V63 it calibrated just fine but on V1 and V61 it gave me this error. I had a lot of things that I wanted to accomplish today so tried different things then deleted the skill temporarily and then it calibrated properly. I was using the Stepper servo skill. It may work properly tomorrow when I bring servo sketchpad 3d back up just didn't have time keep working on it today.

I noticed an update was done to the servo sketch 3d. I think there was a fix in there for a cross-thread call. If you update the robot skill when you load arc, it shouldn't happen again.

Today's project was to cut 9 stringers for stairs. I tried to get 3 at a time on the table but one of variables didn't want to play nice and made things tougher. Will get 3 at a time in the near future. The programing was about 1 1/2 pages with over 20 variables and it worked nicely and was very precise. It takes about 13 minutes per stringer
