Hi:
I want to useRoboDK to generate an offline program, and then copy this program to the teach pendant achieving 3D printing.

Currently, by modifying Programe Events "Extruder(%1)" as theinput and output instructions,I can save the E value in the LS file.

When the LS file is executed, theE valuecan be sent to the robot controller.


I wonder if we can use a similar method to save the printing speed as theinput and output instructions (viz. as(%1)).


Thank you very much.

Hi Loaferhit,

I'm not so sure to understand your question.
If there's a set speed in the G-code you are using, it will be transferred to the robot controller via the LS file as each motion has it's speed command.

What kind of integration are you trying to achieve?

Hi Loaferhit,

I assume that you are talking about the F value of a G1 command (it's called feed rate) ? If so, I believe this parameter is also taking care of by RoboDK's program events. If I remember correctly, it will create a "setSpeed()" instruction with the F value.

Hi JFCh,

Yes, I think he got confused a bit between the robot speed and the extruder feeding rate.
Here's another one of his posts.

Maybe you can take a look to make sure I didn't say anything stupid.
I know robotics, but 3D printing, not so much.

Hi JFCh and Jeremy:

我想把机器人的进给速度(即Fvalue of a G1 command) and the extrusion speed of the extruder to the PLC at the same time. we want to use PLC to synchronize these two speeds. Now I don't know how to convert the robot's feed speed into I/O instructions.

As JFCh said, can "setSpeed()" be used to convert the feed rate? I tried it and don't know how to create a "setSpeed()" instruction with the F value.
thank you very much!!!

Hi Loaferhit,

The feed rate is already converted to setSpeed, this is automatically handled by RoboDK. You don't need to do anything about it.
For the extruder speed, as we already said, RoboDK will transfer this information as a program call "Extruder(extrusion speed)".
You then need to create a program on your controller called "Extruder" to catch the extrusion speed and send it to your PLC.
There's not much more I can say about that.
