@engikeneer said in considering update from 2.x to 3.x:

but also meant I understood my config a lot better.

Which is one of the reason I do not recommended becoming dependent on the configuration tool.

@Co3get, here is my heater section of config.g:

; Heaters

M308 S0 P"bedtemp" Y"thermistor" T100000 B4200 ; configure sensor 0 as thermistor on pin bedtemp
M308 S3 P"e2temp" Y"thermistor" A"bed sense 2" T100000 B4200 ; configure alternate or second bed heat sensor
M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
M140 H0 ; set bed heater to heater zero
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M307 H0 B0 S1.00 ; disable bang-bang mode for the nozzle heater and set PWM limit
M308 S1 P"e0temp" Y"thermistor" T100000 B4200 ; configure sensor 1 as thermistor on pin e0temp
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
M143 H1 S280 ; set temperature limit for heater 1 to 280C
M307 H1 B0 S0.6 ; disable bang-bang mode for the nozzle heater and set PWM limit
M308 S2 P"e1temp" Y"thermistor" T100000 B4200 ; configure sensor 2 as thermistor on pin e0temp
M950 H2 C"e1heat" T2 ; create nozzle heater output on e0heat and map it to sensor 2
M143 H2 S280 ; set temperature limit for heater 2 to 280C
M307 H2 B0 S0.6 ; disable bang-bang mode for the nozzle heater and set PWM limit

It's been a while since I set that up so am not too sure what all was done.
I do know that in order to display the second bed temperature on the graph in DWC, you need to go into the 'Extra' bit of the 'tools and extra' pane and flip the 'show in graph' thingy.

Hope that helps.

Yes, middle of bed for the sensor, offset a bit to not be directly where the bed wires go into the heat pad. I don't think it makes much difference exactly where it is located as long as it is somewhere in the middle-ish.

There is little difference with respect to reliability; thermocouples are more noise prone but needs a daughter board. PT1000 are preferred for the Duet3 but a 10k or 100k NTC will work just fine as well.

You can't rely on the colors of the wires with stepper motors as there is no standard. You will need to identify the phase pairs and wire accordingly.

For the Duet 3 you'll need to use the provided crimps and shells for the larger Duet 3 motor plugs.

If the old motors was 1.8 degree and the new motor is 0.9, you will need to double your steps per mm.

@Turbo I used to think the same thing, but you'd have to have EXTREMELY low jerk and accel values to not reach 100 mm/s on print moves larger than a few mm.

For example, even starting from stand still, at 1000 mm/s/s accel, we reach 100 mm/s in 0.1 second, or about 5 mm of distance.

@Co3get said in looking for good starting gcode:

G28 Z10 ;move Z up

That is not doing what you want. Do a G1 Z10 F6000, or similar G1 command. That will fix a lot of things; do that first and adjust from there.

Looks like you are running incompatible versions of RRF and DWC. What version of RRF are you running? Send M115 to find out.

@Co3get Glad to see you got it working. while pondering your situation I remembered that some cables are just for charging thus no data flow.
