@fcwilt Yes, that's it. I connect to the firmware via http-request.

Let's say we have the following case: Someone processes a movement with a specific feed rate, for example F1000. Afterwards he/she wants to increase the value by 500, but doesn't know the last F-value which was specified in the first run. To increase the value by 500 I need to know the last specified F-parameter to add the increment.

THANK you very much!

@chrishamm Thanks for your answer. The requested speed is only displayed while a print or move is running. I need to know the last value which was defined bei G1 Fnnn.

Hello together,

I would like to know, if there is a possibility to read the currently set speed (as set via G1 Fnnn). While the machine is working the current and top speed is displayed correctly.

The goal is to change the speed by using an incremental value.

The max speed is readable at the machine properties page.

Thanks in advance,
Gabriel

Perfect, THANKS!!

Hello all together,

I remember a github page from chris hammacher which explained the connection between Web Control and RepRap Firmware. For example, he wrote how to connect via HTTP-Request (rr_status?type=001), which timeouts need to be taken account to and more. Unfortunately I can't find it anymore. Was it deleted?

I am about to create a LabVIEW based user interface.

Thanks in advance,
Gabriel

It works now as expected. Perfect!

@dc42 Of course, I completely understand. Anyways thanks a lot!

Thank you very much! This is the best support ever!

Hi dc42,

yes, just a single Z probe. It doesn't matter if I try G30 or G30 S-1. Firmware is

Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet Ethernet 1.02 or later
Firmware Version: 2.02(RTOS) (2018-12-24b1)
Web Interface Version: 1.22.6

Thanks for your fast answer,
Gabriel

Hello everybody,

I mentioned a strange behaviour.
My coordinate system is set in the center of the working space, because there is the pivot point of my goniometer stage which results in the u and v axis. When I use the command G30 to start a single probe, the movement direction is always in the direction of Z = 0. That means, if the nozzle is right above the goniometer stage at Z = -80, G30 moves the nozzle up. If the nozzle is at Z = 10, it moves down.

Is there any possibility to force the movement to go further minus?
My config.g

Thanks a lot in advance.
