Duet Wifi - Accel

[samu_87]

Hello, I'm going to update the firmware in my duet 2 wifi and I wish install the accelerometer on my printer. I must do some modification and I wish understand if i can mount the accelerometer not in permanent way on the head of the 3d printer. In other word, I can install and wire the accelerometer only during the setup of the printer or it's useful during printing? Thansk!

@samu_87 yes you can install the accelerometer temporarily. Its main use is to make it easier to identify the resonant frequencies to tune input shaping. Currently, RRF does not support any other use for it. It might be possible to use a head-mounted accelerometer as a Z probe, however the response time would be poor so a slow probing speed would be needed.

If you make significant changes to your printer hardware (e.g. you change the hot end for one with significantly different mass) then you may need to mount the accelerometer again so that you can re-tune input shaping.

@dc42 Many thanks! I'm going to made the update

[samu_87]

@dc42 I upload the RRF 3.4.5 and I had to update all the parameter that are changed, but I try to install the input shaping plug in without success. I follow this:

But return the DWC return me this message:

So I try to upload in System -> Upload System Files and do somethings but I can't se the plugin in the GUI.

Some help?

Thanks!

Are you uploading a single zip file or has the zip file been extracted first?

It must be a single zip file.

@Phaedrux I'm not sure plugins can be uploaded using the upload and start button in DWC so I think the wiki is incorrect

[chrishamm]

@jay_s_uk Yes, installing plugins via "Upload&Start" is supported so the documentation is correct.

@samu_87 Please make sure you are actually using DWC 3.4.5, the error notification looks like it is from an older DWC build. If you are sure that you installed it, try to force-refresh DWC via Ctrl+Shift+R or clear your browser cache.

[samu_87]

@chrishamm I install this:

Where I can control if the DWC is correct?

I have a lot of problem to migrate to RRF2 to RRF3 maybe is better that I delete all and make a clean and fresh installation? If yes how?

Thanks!

[samu_87]

@Phaedrux I upload the exact file that I download...

[chrishamm]

@samu_87 Yes, that's the firmware but not the web interface. Just upload Duet2and3Firmware-3.4.5.zip without unpacking it first, then the web interface is updated as well.

[samu_87]

@chrishamm Many thanks!!! now I see the plugins!

Can some one help me to adapt my config.g because cannot make the home correctly and if some one can help me to update the parameter. Thanks homedelta.g

[samu_87]

Here the big difference, the homing sometimes don't work well and return me the message "Position can't be reach"...

I have traditional optical end stop and I have the piezo probe.

[droftarts]

@samu_87 your M574 endstop settings should be X2, Y2 and Z2, for max end endstops. I assume this machine is a delta?

@droftarts Thank you so much!!! The problem was there, now I'm going to setup fans and heaters OMG

Hi, I think I configure Bed and Hotend well but the printer can't extrude:

Some help? Thanks!

[Phaedrux]

Your tool definition is missing an extruder drive assignment.

You must add D0 like this to your tool definition.

M563 P1 S"tool1" H1 F0 D0

This assigns the first extruder drive to the tool.

It would be easiest if you copy and pasted the text of your config.g here so we can see the whole thing at once.

You can also send M98 P"config.g" in the gcode console and you may catch some error messages.

[samu_87]

@Phaedrux Thanks! I Add M98:
I don't understand why drive 0 is not ok.
If I add D0 at M563 the tool 1 disappear...

[Phaedrux]

Please copy and paste the text of your config.g here so we can see it all?

[samu_87]

@Phaedrux Yes!
