The bed.g file is needed only to do G32 bed probing, not for homing Z.

Have you tested the Z probe and it configuration as described at https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe ?

@David

Thanks your advise and tested the voltages with multimeter as follows.

Voltage when Jumper header on VIN : 28.3 / 28.3 / 28.3 / 15.6 / 0 (always-on / always-on / PWM0 / PWM1 / PWM2)
voltage when jumper header on 5V : 5.6 / 5.6 / 5.6 / 3.2 / 0
voltage from PSU : 28.3 (It should be 24volt but figures on multimeter 28.3)

Now I understand my PSU supplies some high voltage different from rated voltage and it made the fan out of order. In this case what can I do?

I think one option is just use 5Volt fan OR change PSU. Any other options?

In the meantime, can you advise why PWM2 on Duetwifi and all 5 PWM pins on DUEX5 shows 0 voltage, and shows 15.6volt on PWM1 on Duetwifi? PWM voltages varies depend on G-command in config.g file?

Thanks.

Sorry to hear of your problems. What I meant about putting a "T" command in the start code was basically just to make sure that Slic3R had selected the correct tool for the object you want to print. If you don't assign a tool (extruder) to the object then Slic3r will default to not putting a "T" command in the gcode so you can get the situation where you try to extrude with no tool selected.

I find it's easier to enable skirts in Slic3R (not brim), to purge the hot end at the start, rather than using all those manual extrusion commands.

Thanks so much for your quick response and wish my understanding is correct on your recommendation.

4 z-motors : one to ZA and one to ZB pins separately and another 2 motors to Y-pin in series. 2 y-motors : E0 and E1 pins separately.

And endstop is Makerbot mechanical endstop and found instruction on Duetwiki.

Makerbot Mechanical Endstop v1.2
Connect it to the Duet endstop connector as follows. Note: the pins on the Duet endstop connector are not in the same order as on RAMPS!

Unfortunately the pin markings on the Makerbot endstop board are hidden underneath the connector. Pin 1 is next to the long edge of the board that does not have the microswitch on it, and pin 4 is nearest the edge with the microswitch.

These devices produce an active-low output, so use the S0 parameter in your M574 command.

So I guess voltage is correct 3.3v but need to do re-crimp as pin order is adverse and set S0 at M574.

End.

Appreciate for your confirm whether above is correct.

Thanks.
