Thanks. That's what the problem was. Updated iap4e.bin and then applied the duet2combinedfirmware.bin. It worked as expected. Thanks for the help.

My Duet Wifi board is currently

Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 1.21 (2018-03-21)
WiFi Server Version: 1.21
Web Interface Version: 1.21.1

(FROM DWC)

When I try to update to Firmware 2.0, It says the firmware is being updated. When the firmware finishes updating, It still only shows Firmware version 1.21. I've been using the Duet2CombinedFirmware.bin. I'm not sure if i'm doing something wrong. Any help would be appreciated. Thanks

@DjDemonD:

@NYT - whats the content of your clear heater faults macro (I am just being lazy)

I personally use M562 P1 is what I use (only one extruder and never had a fault with the bed heater)

There is probably a move command to move the printing head up in the z direction in your ending script in s3d. I believe the DWC reads the last move command in the gcode that specifies an absolute distance and uses that for the layer calculation.

@SpeedyDad:

Here's mine:
M207
Retraction/un-retraction settings: length 2.00/2.00mm, speed 1000/1000mm/min, Z hop 0.00mm

Does that mean it is retracting 2mm instead of the 5.5mm I set in my slicer?

It depends on the slicer and if the slicer has firmware retraction enabled. If firmware retraction is enabled in the slicer, then your retraction settings are what is output by the M207 code (assuming the slicer enables g10 / g11 commands for retraction). If slicer does not have firmware retraction enabled, it will be using the settings from the slicer. I was curious to see if firmware retraction was being used and if someone put in a bad R value in the M207 command line.

Rnnn positive or negative additional length to un-retract

Are you using firmware retraction? Also, can you type M207 into gcode console and post the output?

I have a Cartesian printer with dual z screw on a duet 0.8.5. Right now I have them wired in series to the z stepper. If i want to control the 2 z screws with independent steppers for each z (one connected to the z stepper and one connected to the e1 stepper). would i use the following code in my config.g:

M584 X0 Y1 Z2:3 U3 E4?

Are there any other modifications i need to make to the config.g or other files?

Any help is appreciated.

Thanks

@elmoret:

1.) Yes, though it might possibly need a load on the 5v rail to hold steads 12v.
2.) Yes
3.) As many will fit in the provided ferrule.
4.) Use the ground wire. -12v is 12 volts below ground reference. If you used +12v and -12v you'd get 24v, but -12v is only rated for 0.3A.
5.) If you want to, sure. I'd probably coil them up next ot the power supply with heatshrink on the ends.

Thanks for the info…..I connected the PS sense line to the lead it was coupled with in the ATX connector.

Exactly there info I was looking for...Thanks

I have a 600w ATX power supply (EVGA 600B) with the following specs
+5V@20A, +3.3V@24A, +12V@49A, -12V@0.3A, +5VSB@3

I would like to use this to power the duet but have a few questions first.

1. Will this Psu work?
2. The 5v standby, ps-on and a ground lead from the ATX PSU to the external 5v connector next to main power in?
3. The main 12v power in, how many 12v leads (yellow wires from PSU) should / can I bunch together for the + terminal in a terminal block?
4. For the - terminal on the main power input, should I use the ground wires from the PSU or the single -12v lead on the PSU? Does it matter? If I use ground can / should I bunch a few together in a terminal block?
5. Do I need to keep any additional spare 12v leads and ground for future expansion?

Thanks for any help you can provide
