Program Event or Function Call for 3D Printing Extruder Control

#11
Hello Patrick!

Thank you very butch for sharing your workflow anf scripts for CS8 controller.
I have the similar model (CS8C TX60 robot) and I can not deal with MoveL commands and RunOnRobot mode at same time. The MoveL working good while I upload to robot, but when I run on robot, gives me an error (soflimit reached). The MoveJ command just working good.
How did you deal with this situation? I tried all posts and I have installed HSM Machining on SC8C so I tried the machining post as well. All of them working the same - giving me fault at MoveL.

Bests,
Eduard

Hi !!
Please help I put the program in the postprocessor

Code:
def ekstruder():

   # This script shows an example to integrate an extruder with RoboDK
   # We need to add this script to the RoboDK project ot trigger sending the E value (Extruder parameter)
   # This script meant to work when we are running 3D printing with the driver ("Run on robot" option)

   # Send the E_Value over Ethernet (ASCII numbers)
   EXTRUDER_IP = '192.168.1.15'    # The IP of the extruder
   EXTRUDER_PORT = 100            # The same port as used by the Extruder server

   E_Value = None

   import sys
   if len(sys.argv) > 1:
       E_Value = float(sys.argv[1])

 
   # Implement socket communication to send the E_Value over Ethernet/socket
   import socket
   BUFFER_SIZE = 1024

   # Build the byte array to send
   bytes2send = bytes(str(E_Value) + '\0', 'ascii')

   print("Sending: " + str(bytes2send))
   print("Connecting to %s:%i" % (EXTRUDER_IP, EXTRUDER_PORT))

   # Connect to the extruder and send byte array
   s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
   s.connect((EXTRUDER_IP, EXTRUDER_PORT))
   s.send(bytes2send)  
   s.close()
   

The program connects to the printer and sends the G-code I'll capture the extruder value

Code:
  if code.startswith("Extruder("):

   # Intercept the extruder command.
   # if the program call is Extruder(123.56)
   # we extract the number as a string
   # and convert it to a number

   self.PRINT_E_NEW = float(code[9:-1])
               
   sys.argv = str(self.PRINT_E_NEW)
               
   self.uruchom_ekstruder() ?????? !!!!!!!!!!!!!!!!!!!!!!
       return
   else:
   self.addline(code + "()")

How to call extruder () functions ??
The robot reports an error Am I doing it right?
Thank you and greetings

Code:
import sys
if len(sys.argv) > 1:
   E_Value = float(sys.argv[1])

code_E = 'G1 E ' + str(E_Value)

f_value = None

# Check if we are running this program inside another program and passing arguments
import sys
if len(sys.argv) > 1:
       
   f_value = float(sys.argv[2])
   
if f_value is None :
f_value = 0

f_transform = f_value * 60 * 1.5676 # mm/s in mm/min und adaptation for line crossection Q to fed filament Q/pi*(2.85/2)²

code_f = ' G2 F' + str(f_value)

The script reports an error

How do I assign the SPEED_MS variable to sys.argv [2] ??
Self.PRINT_E_NEW is assigned to sys.argv [1]
I want to read these two variables with sparks

Code:
import sys
if len(sys.argv) > 1:

   E_Value = float(sys.argv[1])

Code:
mport sys
if len(sys.argv) > 2:
  e_value = float(sys.argv[2])

if f_value is None :
f_value = 0

I can't pass SPEED_MS to extuder speed I want to send two parameters, speed and quantity of filamant

Thank you

Hello, it seems like you have resolved your issue.

I would like to ask you about our 6-axis FANUC robot. I encountered a problem where the robot doesn't move when I use the command robot.RunInstruction('RMACRO2', INSTRUCTION_CALL_PROGRAM). I suspect that it might be related to my online programming.

Our workflow involves using the arm through the FANUC robot's vision system for tasks such as gripping and grinding. The process is as follows:

Computer > ROBODK > FANUC robot > FANUC internal vision program > ROBODK control

Could you please provide any suggestions or insights on why the RMACRO2 instruction is not working for me?

I just got back to you on this question on your post from another thread:
