Hello Johannes,

Thanks for your help, I would like to know if there is a way to anticipate "x" seconds a Custom KRL command.

Basically i want to turn off the extruder "x" seconds before the supposed position to avoid excess material extrusion because I have a pellet extruder.

Or there are other strategies for this?

Hello Johannes,

I used the extrusion mode "D6" but now i want to change all commands DO6=FALSE for the "Custom KRL" component DESLIGAR_EXTRUSAO() and DO6=TRUE for the "Custom KRL" component LIGAR_EXTRUSAO().

How can i do this?

Perfect.

Now I want to connect to the digital output to the robot. I have two functions saved in the robot "DESLIGAR/EXTRUSAO" AND "LIGAR_EXTRUSAO" that are the procedures for turning the extruder on and off and I want to call them in the code.

I attached the file that I did for this and I would like to know if this is the right/best way to do it. I have a lot of doubts. I would appreciate your feedback.

I changed the extrusion mode for "D", and I noticed that it inserts the digital output in the code.

Just to confirm. The command determines whether the extrusion is positive or negative and adds an on/off command accordingly?

Best regards

Hello Johannes,

Thanks for your help, that was what I was trying to do. Dont get me wrong, for sure im not the best person to judge what its easy and not.

Now I'm trying to use the g-code import command and I want to convert the E value to a on/off command of my extruder.

Any advices or there are some examples that i can check?

Once again, thank you for all your attention.

Hello Johannes,

Thank you for all your help, it's been very helpful.

I dont want to have a zig-zag infill plus a perimeter that start and end at the same point, I want that the end point of the first contour ( first layer) be the start point of the second contour (second layer). I think that's not hard for someone who have skills in grasshopper, that's not my case.

I attached a scheme that represents what i'm trying to do.

Hello,

I attached the file.

The geometry is a simple rectangle with a zigzag structure inside (infill). My goal is to have continuous extrusion and for that i need that the end point of the countour command of the first layer be the start point of the second layer and so on. This way i can avoid the travel movement from the end point to the start point every layer.

If there is another way to do this?

Best regards,

Once again, thank you Johannes.

I have another question, I have a simple tool path obtained through the contour function. But I wanted that the last point of the first layer become the start point of the next layer and so on, so the extruder doesnt travel to the start point. Any suggestion?

Best regards,

Hello Johannes,

Thank you for your attention. I already sent an email.

About the strategies used for design the infill in this kind of process, there are any tips or examples how its normally done?

Best regards,

I´m new in this world of using grasshoper and kuka_prc for 3d printing with a kuka robot.

I would appreciate if someone could give me some tips.

First of all i´m interested in importing G-code to kuka_prc, I read that the feature is only for members. There is a way i can get a temporary license to try that feature? There are some tutorials about this subject?

Other subject that i'm interested is about the strategies used for design the infill in this kind of process. Any tips, examples or tutorials that can help me?
