For one of my RoboDK projects, I set the blending radius to 5 mm. However, when the robot moves vertically along a curved path, the motion from one point to the next becomes very abrupt instead of smooth.

I was wondering whether this could be due to too few points along the curve.

Could it also be because the printed object is very small, so the robot is not effectively applying the blending radius?

Please refer to the attached video for reference (it only shows the motion without extrusion).

As you can see all of the toolhead tilt for now is done in the A direction (about the X-axis). Currently this is being ignored in RoboDK. I can change the output of the CAM software if needed, I just need some direction. I've read through and watched several videos on the topic, I know I'm likely missing and older post and I apologize if I've missed it.]]>

To provide more information, I solve the transformation between each joint using the transformation matrix in the image attached, then I multiply the transformation matrices for each joint to get from the base to the flange. I don't have any additional tools on the robot, so I don't have any additional transformations to get to the TCP.

Thank you!

I’m having trouble using the Attach command. The object does not attach to the tool and stays in place during the simulation.
 Could you tell me what possible causes I should check?
The tool and object seem properly aligned, and the command is being called in the program, but it still does not work.
Any advice would be appreciated.

Best regards,
Keisuke Sakai

We have Fanuc M-900iB/360 on the floor and I am trying to create an offline simulation for it. I cannot reach one of the position due to J2 hitting its limit in simulation but I can reach it in reality. I tried to modify J2 limits but I couldn't. Joints I am trying to reach are -94.916, -59.457, -2.508, 104.866, -4.913 and -79.986. But simulation robot has limit of -44. How do I change that? Thank you.]]>

I would like to ask how, if it exists, where could I access this post processor? if not whats the closest thing I can use to generate my path from robodk as a GST file?


Note: I already sent an email but wanted to post here in case anyone has a solution.

Since the robot and positioner cannot synchronize the movements together. I would need to move them one after another but I want to make the positioner stay at a fixed position. In RoboDK itself I can set the weights in the Optimize External Axes panel to be 100,000 for the positioners to not move. But how would I export or modify the post processor for the script for the robot to use. Where the robot talks to the PLC to tell the positioner to rotate to it's angles then the robot continues with it's movement?

An example of the scripts flow would be like:

Code:
START
Rotate Positioner Axis 1
Rotate Positioner Axis 2
Robot Movement
..
Robot Movement
END

I have been working on a curve follow project using a UR5e to sandblast a rectangular (rounded corners) shaped component but the movement takes longer on the radius corners than on the straight paths leading to non-uniform finish and failed parts. When analyzing the generated code there are many linear movements generated at the rounded corners. I try to speed up the operation speed but I still have a speed difference between the straight and rounded paths. The path is 2D imported from SolidWorks using the RoboDK plugin. When I try to use arcs as the output I receive an error on the blending radius being too small. I’ve tried breaking the program up into separate curve follow projects but the robots interpolation between curve follow projects is non-uniform and leads to strange movements. 

Help or advice would be greatly appreciated, thank you!]]>
