@JayJay Just for the sake of clarity.

M280 commands are servo control commands. The BLTouch uses a servo to deploy and retract the pin. For the BLTouch you put the M280 commands in deployprobe.g and retractprobe.g

M401 and M402 call the deploy and retract macros. That's all they do. When using a BLTouch (probe type P9) G30 will call M401 and M402 automatically.

In the days before the P9 probe type specifically for the BLTouch, you had to manually deploy and retract the probe before sending G30. Using the base M280 servo commands was common, however M401 and M402 were added so that the firmware could actually keep track of the state of the probe as being deployed or not.

So yes, using M401 and M402 in your homing files when using a BLTouch isn't needed anymore because probe type P9 takes care of deployment and retract automatically. But behind the scenes it's still just using M401 and M402, which is just calling deployprobe.g and retractprobe.g which just contains the M280 servo commands.

I hope that gives some historical context and explanation on why things are the way they are.

@JoergS5, I sit corrected ... I will have to try this out.
Thanks!

@dc42 It solved it for me

@jdumoulin said in Error: M350: Driver 20 does not support x8 microstepping:

E0.20

Scratch all that. I finally found the typo. Im sorry to have wasted your time on this. I checked this thing over and over.
Extruder was listed as E0.20 instead of E20.0

@jay_s_uk @deckingman thanks for the info i will do that especially if the release is stable

@jdumoulin said in Cannot change can address with M952: Command is not supported:

So where do I find information on how toset up this tool board in the config file? It is not listed at all in the documentation.

Set up the fans. drivers, heaters etc. in config.g just as you would set up a local driver; except that the driver number on the tool board is 20.1, the high current (heater) output is pin "20.out0", the 12V outputs for fans are "20.out1" and "20.out2", the temperature sensors are "20.temp0" and "20.temp1", and the IO (Z probe) connector is "20.io0.out" and "20.io0.in".

If you want an example, you can find a config.g file for a tool changer with one tool board (at address 23) at https://github.com/Duet3D/RRF-machine-config-files/tree/master/E3D_Tool_Changer/dc42-duet3-centreZero-2Titan-2Hemera.

PS - the full list of tool board pin names, excluding the motor driver, is at https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Duet_3_Tool_Board_1LC_pin_names.

@Nuramori said in Tool board to Duet 3 wiring:

I followed danal’s directions, as I asked your question a week or so ago too - works perfectly. The key was the terminating resistor.

Thank you. It is working now

Needs to be built for cygwin if to be used on windows; for the pi its just git clone and make, no dependencies to deal with and the default image has the build tools it seems.

Not sure if the last command is needed to get the processor out of boot from ROM mode, can't test it. (and I just realized this was the wrong thread, but if OP has a PI...)

git clone https://github.com/atmelcorp/micro-sam-ba.git cd micro-sam-ba/ make ./usamba /dev/ttyACM0 erase-all ./usamba /dev/ttyACM0 write /opt/dsf/sd/sys/Duet3Firmware_MB6HC.bin 0x400000 #./usamba /dev/ttyACM0 gpnvm set 1

@jdumoulin Duet 3 with SBC? If you’ve tuned your heaters and saved with M500, it saves the heater tune M307 with empty parameters. Known bug, being fixed soon. Either that or you have no config_override.g file!

@jdumoulin
Hey
Can you share Tour g.code?
I have the same problem.
Thanks

@patel said in Duet 3 setup issues:

@bearer
Connection say out 0 and out 0
Why they call out put but in wiring Diagram say In put.

The flow of power on the thing called "Out0" is controlled under that name in configuration: "Out0". The thing called "Out0" is setup to handle a bed heater.

Physically, there is a way to get power IN to the Duet board for this whole bed heating system that is named "Out0", the middle two screw terminals.

There is also a way to get power OUT of the Duet board and on to the bed for this whole bed heating system that is named "Out0", the rightmost (in the diagrams above) two screw terminals.

Repeated another way:

The thing called Out0 in configuration switches the power that flows from screw terminals IN, through the board, to OUT.
