Hi Jay,
thanks for your fast reply. This workaround removes the error message, which is definitely an improvement!

From my point of view, as we use the Duet 3 in various machines as subcontrollers for axis systems, it would be desirable, that the webinterface only shows the axes which are defined in the config.g. Maybe it will be realized in future firmware versions.

@o_lampe thanks for your reply. It's a chain drive that is moving some parts in circle.

The supply voltage of 36 V is no problem, as we modified the Duet so it can be used up to 48 V. The thing is, the chain drive can also manually be driven without the plug put into the wall outlet. And this is even wanted!

Hello everyone,

just one short question:

• is there any possibility to destroy the Duet 3 6HC or its stepper drivers because of moving the axes manually in idle mode or when VIN is turned off?

I remember the LEDs of the stepper drivers of the Duet 2 turned on while moving an axis manually.

Thanks in advance and greetings from franconia,

Hello everyone,

I am using the DUET 3 for an axis system inside a climate chamber which has a carousel as x-axis to move parts in circle and a z-axis to get in touch with the parts every once in a while.

Obviously there is no y-axis configured but in the web interface the y-axis is shown anyways. Is there a possibility to just show the x- and the z-axis? There is the M584 P2 / P1 command but this doesn't hide axes located in between (normal order is xyz abc/uvw). So it is possible to just show the x or x and y or x, y and z.

So all in all the question is:
Is it possible to realize that only the x- and the z-axis are shown in the web interface? also I would like to avoid the error message when homing all axes, which indicates, that y couldn't be homed.

Thank you very much in advance and greetings from bavaria,
Gabriel

@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!
