Re: Duet WiFi with E3V6 dragging on plate

I suggest you check your config-override.g file again for G31 commands.

Either there is a bad crimp connection in the motor cable, or the stepper driver chip is faulty.

Re: Some PID Tuning Quirkiness

You shouldn't really need to run PID tuning when you change the temperature, unless you experience problems. It's better to tweak with M307 (see config-override.g for the M307 command that was saved when you ran M500): Reducing D improves responsiveness, but the temperature will oscillate if D is to...

Re: My printer has gotten an attitude.

More likely the firmware isn't smart enough to keep the motors in sync when it can't generate the steps fast enough.

Reducing the maximum travel speed may be a temporary solution until you get a faster controller.

Re: Duet Wifi Endstop issue

That type of problem usually means that you have a pair of motors or endstops swapped where they plug into the Duet. Please test the motors individually as described at https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareDeltaPrinter#Section_Testing_the_motors_individually to make sure that you ...

After a layer shift has occurred, run M122 and check whether any under-voltage events have been recorded.

Re: Duet 8.5 Groundwire overheating

The reason we tell users not to tin the wires themselves is that if you do, it is absolutely guaranteed that the solder will creep and the joint will work loose. Anyone who does tin the wires themselves will need to re-tighten the screws frequently until they stop working loose.

Re: Hot End Chattering/Bouncing Against Bed, Not Much Extruded (Bad config.g?)

If the supply voltage to the TMC drivers drops below a certain voltage (somewhere around 9V AFAIR) then the drivers shut down and they need to be re-initialised when power is restored. So when the firmware detects that the voltage has fallen below a slightly higher voltage (9.5V AFAIR) we shut the d...

Re: Duet 8.5 Groundwire overheating

Looks like the screw terminal because loose. This happens when you put high current stranded core wires into a terminal block without crimping ferrules on the wires first (that's why ferrules are supplied with Duet WiFi and Duet Ethernet boards). You can usually get away with it if you re-tighten th...

Re: E3d v6 thermister settings for duet?

According to E3D the thermistor parameters are unchanged between the old and the new types.

Note that it's not just the B value that you need to set, it's important to use matching B and C values in the M305 command.

Re: Cura 3.1

The lines that extrude 0.15m also have about 3mm of X or Y movement, much more than the other lines, so more filament needs to be extruded in them. When you select RepRap flavour GCode, Cura defaults to relative extrusion, which is what RepRapFirmware prefers. So use it if you have Duet electronics....

Re: Looking for auto-leveling recommendations for my Metal Max

Another possibility is to swap out your effector and arms for the Smart Effector and magnetic arms (see https://www.duet3d.com/DuetAddons/DeltaSmartEffector) but that's probably overkill if you are happy with the existing arms, effector and hot end.

The Duet WiFi and Duet Ethernet already support stall detection, see https://duet3d.com/wiki/Stall_detection_and_sensorless_homing. However, it is of limited use on a delta printer, because motors don't produce enough back emf at low speeds for stalls to be detected. On delta printers some of the ca...

You can also run the Duet WiFi in access point mode, without a router. That's about as simple as it gets! Needs firmware 1.20 or later, and of course a smartphone/tablet/laptop/PC with WiFi.

There should be a positive click when the SD card is seated properly, then to get it out you have to push it again.
