Support request using RoboDK for Additive Manufactuting
#1
Hi everybody,

For the past two years, we have been successfully using RoboDK to 3D-Print using an Industrial Robot.
We appreciate the ease of use of your software.
 
Currently we are researching, how tilting the nozzle effects tensile strength. Therefore we want to print tensile test specimens using different angles of the nozzle.
As a first approach, we want to print a specimen were the nozzle is tilted at a constant angle during one print, but: keeps the melt in front of the nozzle (see left part of  picture, case I)

With the current settings, we only achieve a constant switching between cases I & II, after each thread is complete. This is not desirable, as the melt is either dragged of pushed. But we want to isolate these two cases.

Here you find the files.
 
Now we are wondering, if you know an easy way to solve the issue using RoboDK.
I was thinking if there is some way to “bind” the angle of the TCP to the movement direction vector of the robot flange.
 

We would greatly appreciate your feedback.
 
Regards and many greetings from Germany,

Maurice

Hi Maurice, 

I took a quick look at your project. 
I think that you missed one of the crucial options for this to work:

   

But you will still be stuck with the mechanical limitation of the robot. 
Let me know if it helps.

Hi Jeremy,

thanks for your fast reply!
Thats the kind of stuff that takes 2 seconds if you know how, but hours if you don't...
We will try it out ASAP und let you know.
The simulation looks good...

Regards
