@hauschka Alternatively, if you are likely to switch back and forth, you could create two (or more) configuration files and switch between them. Check out M505 https://docs.duet3d.com/User_manual/Reference/Gcodes#m505-set-configuration-file-folder

@phaedrux I'm using Simplify. I add new one gcode in Python DSF which set temperature for all beds and replace M140.

But I still don't understand why it's impossible to configure multiheater bed. For extruders it works nice.

@mjlew the speed and acceleration limits set in config.g are enforced regardless of where the movement command comes from.

@phaedrux OK, thanks.

@t3p3tony oh ok, stupid me, it gets copied in /etc/wpa_supplicant/wpa_supplicant.conf

So i tought my board stopped connecting because of that but obviously must have some other prob.

thanks.

@vaibhav-jain said in Dimensional Issue - (Hexagon side-to-side length):

do I need to delete the config-override.g before calibration ?

No, as long as you send M500 after the calibration the config-override.g file is re-created with the current values.

@phaedrux
all work. it was the motor mapping. Thanks you so much for your help

Could we use the heatsink as GND? that would make the slip ring much easier and reliable. The heatsink could rotate on brass bearings for better contact and heat-immunity. The way the 'heatbrake' looks, it has full contact to the heaterblock and the heatsink, no real heatbrake unless it's made from utopium

@o_lampe we continue to manufacture the Duet 2 mainly for our OEM customers, and they don't want any changes to the connectors because then they would need to change their wiring looms.

Flash memory is now full on the Duet 2 and RAM is getting tight too. In RRF 3.5 there are likely to be new features that are not available on Duet 2.

@wwak84 The problem with multiple nozzles is that it is almost impossible to prevent oozing filament from unused nozzles being deposited on the print or cooling and causing a head crash. I'm not the OP, but I'd guess that's what he is trying to avoid. Personally, I prefer to use multi input single output hot ends which have a single nozzle. The other alternatives are a tool changer or a multi-filament unit.

@jered said in Using Duet to control robot arm:

I can get hybrid stepper/servo drives that will work with the 1XD boards. That's what I use on my cnc.

The MB6XD board may be a better choice now, if most or all of the motors will need step/dir signals.

@chriswhiting Thanks so much for responding so quickly and providing A grade assistance

@dc42 ok, great

thank you.

Thanks for the update. We probably should have asked you to ensure all other hardware was disconnected and starting from that state. 😥

@feynman137

It appears the issue was incompatible firmware between the expansion board and my mainboard but I issued the M997 command and now I can turn on the heater.

@phaedrux Ok, thanks.

@lastmark It's pretty unlikely that RatRig would have gone to the trouble of creating and uploading a configuration file but it's easy enough to check. Option 1 with no power on the board, is to remove the SD card and put it in your PC. Look in the folder called "sys" - that's where confg.g will reside if it exists. Option2 is once the board is fitted and wired up, open up the web interface and look at the system files.

@phaedrux thanks, i revised my custom end gcode which is where those lines were coming from and seems to fix the issue.

@dc42 will try and let you know.

thank you.
