Check the motor connections for Y and E0 - they seem to be different to X & Z (which match mine). Or is that the non-standard motor wiring you mentioned earlier?

Yes, it's the non-standard motor wiring.

Did you see my reply to you - last post on page 4?  About power supply.

Yes, that's the intention but I'll check the config.g file.  Would it be best to connect the board via USB for power to check or would using the +5v_SB from the ATX PSU be alright?

Do you want to see whats in the config.g or test the probe? USB power wont power the board I think. I'm not using any 5V supplies so I don't know what it will power.

Anyone else know?

I want to see what's in config.g.

From the Duet Wiki:

The Duet operates on two power circuits: a 5V circuit that powers the CPU, WiFi, and web interface, (mostly through a 3.3V LDO) and a 12/24V circuit that powers the motors and heaters.

I imaging the +5v power in powers all the logic and processor.  Vin would power the motors, heaters, fans etc.

Snap!!

5v only from the ATX should be ok to see and edit your config files.

Should be alright to run it from the ATX PSU +5v_SB line then.

Signing off for now. I'm not being rude if I don't reply straight away

OK - here goes   If you hear a scream from "way down south" you'll know I have a problem!!

OK Dave - chat later

5v power applied - no smoke - no smell - just lights on

WiFi not working   Realised I could see what's in config.g from the files downloaded from the web based configuration tool.

Think I've found the problem with the WiFi.

Use the System Files Editor in the web interface to remove the leading ';' character in the M552 command in config.g so that the Duet WiFi will connect automatically in future.

But I haven't The ";" is not there in the line "M552 S1              ; Enable network".

WiFi connects fine with USB power.

Edited config.g from the web interface to change the Z probe type from P1 to P4, saved back and rebooted.  It's so easy (when it's working)

So...  Seems I have a power issue.  I'll put the printer back on the table and check the +5v_SB line.  I wonder if the Gnd connection on the Duet +5v IN, PS_ON, GND connector really does want connecting to the PSU Gnd.  Wouldn't have thought so.  I'll get my DMM...

How is the Duet getting its Gnd connection. Via usb?

The Gnd on the connector shows 0.2ohms to the POWER GND terminal and the +5v_SB line reads 5.089v.  Not that then.  One difference is that the LED labelled "Diag" was on before and now it's off.  Still no WiFi connection when powered from ATX PSU.

Found the problem.  Poor WiFi.  Put printer on my office chair and wheeled it nearer the router.  Plugged in to a nearby main power strip and powered up.  Web interface now working.  About 1.5m from router.  At 3m it didn't work.  On the laptop USB connection it was about 2.5m from the router.

Oh dear, it won't work in the workshop then without a WiFi repeater!

I think the tiny antenna on the WiFi module lets it down. There was a discussion on the Forum about having a proper connector & antenna but it puts the costs up too much. I think you may need a repeater or a spare router connected via ethernet.

Now to find out how I turn the printer on

Gotcha

Did that "made it so" and now have On and Off buttons on the page   Lower right-hand corner.

Clicked the green On button and the Vin blue LED came on and the hotend fan which is always on if the PSU is ON from the PS_ON control.

Now testing.  Hotend and bed heaters working fine (plus thermistors).  X and Y movement doesn't work - motors just buzz.  Z works fine except that the direction is wrong - that's soon fixed
