Hello, I noticed this old thread and was wondering if anything has changed:
https://forum.duet3d.com/topic/2985/current-position
We are currently doing a long probe move where it would be very beneficial for us to query the machine position. Thank you!
@dc42 I should clarify that when we use the move.axes[N].machinePosition in Gcode it works well. When using the rr_model with HTTP, it does not seem to have the same functionality.
@dc42 Hi, thanks for the reply.
Yes we have tried that, unfortunately it only returns the position that the machine is heading. It does not output the current position.
Hi all,
Does anybody know of a way that we can pull the current machine position through HTTP requests such as rr_model? Currently , if we use rr_model we are only able to see where the machine is going, not where it is located. Right now, we are finding our machine position through M118 telnet messages imbedded within our gcode. If we could do this externally it would be ideal.
thanks in advance!
@dc42 We are using a Duet 3 MB 6HC with the latest firmware, 3.3 I believe? Alan's answer was perfect, it is exactly what I was looking for.
@alankilian That worked! Thank you very much for the help. I will run with it from here
@alankilian so I used the following line to try to connect to the machine:
sock = socket.create_connection((duet_host, 23), timeout=10)
I am getting this response: [WinError 10061] No connection could be made because the target machine actively refused it
Is there a security setting within the duet that is causing this to happen?
@alankilian Hi thanks for the quick reply. To be honest I am not really sure what I am doing.
Yes I am running the python script from my PC.
I was under the impression that the Duet would send a message to the specified port on my pc. I am obviously mistaken. Let me try to connect to a telnet port on the duet and see how that goes.
Hi all,
I am hoping to read basic telnet messages sent through M118. I am running my Duet in standalone mode and it is directly connected to my pc. I am trying to use the socket library in python to listen for messages, but I am not having any luck. My basic config.g file contains the following:
global g = 0
M586 P2 S1 R23
M553 P255.255.255.0
M552 S1 P192.168.2.80
I am using the following macro to try to test the telnet messages:
set global.g = 0
while global.g < 20
M118 P4 S"message"
set global.g = global.g + 1
G4 S3
And I am trying to use the following super basic Python script to listen:
import socket
import sys
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('localhost', 23)
sock.bind(server_address)
sock.listen(1)
while True:
print(sys.stderr)
print('waiting for a connection')
connection, client_address = sock.accept()
If anybody could help me out I would definitely appreciate it. Thanks in advance!
Thanks for the reply. I will play around with it!
We are just trying to pull the analog readings from our I/O sensors. We have them setup for a linear scale.
Hi all.
We are trying to pull analog data from our I/O pins as quickly as possible. We are currently doing that with the machine/status HTTP request in a Python script. The script pulls the full machine status, isolates our important sensors, and then saves that data.
Is there a faster way to do this? Potentially a method that would not require an HTTP request? We are currently running our Python script from a raspberry pi that is connected to the duet.
Thanks for your help.
Yes that is what we are trying to do! We are not having success with rr_model.
Hello,
I am hoping to replicate the functionality of M409 through an HTTP request. Our successful M code looks like this:
M409 K"sensors.analog[7]"
We have successfully pulled all of the data off of the board using an HTTP request that looks like this:
However we are hoping to only pull relevant sensor data, if at all possible. We have tried playing around with the rr_model function without luck. Any help would be greatly appreciated. Thanks in advance!
We are using the most up to date version of reprap along with a Duet3 6HC
