Well done , similar to my DBot, but i've gone for the dual z motors. I like your print carriage \ cooling fan parts, have you published them anywhere ?

I tried a Titan Aero, but just couldn't get it to print nicely, so I've reverted to a normal Titan, combined with a Precision Piezo, which gives great prints.

It's by design of of the way IP networks operate.

When a device boots-up, if it has been given a static IP address, it will always use that address.

If it hasn't been given an address it will try and contact a DHCP server, which will give it an address, from a pool of address it has been configured for. Depending on your network configuration, but normally for home use, this will be the router that you use to connect to the internet, which unless you know how to make some advanced configuration changes, will be 'factory set' for the pool, to the local subnet of 253 possible hosts (computers).

So there are 2 ways to always get the same IP address:

1. Assign a static address in the DWC configuration, which could have knock on effects whereby the DHCP server tries to assign the same address to another device that connects to your network. this risk can be mitigated by assigning an IP address 'high-up' in the subnet range, e.g. if your IP address range is something like 192.168.1.1 through to 192.168.1.254, then assign an address in the 250's

2. Assign reservations on the DHCP server, such that when the MAC address of your DWC device requests an IP address it is always given the same address.

Try removing\comment out the

M574 Z1 S2 line, I found I didn't need it for my Precision Piezo z-probe , i.e.

M574 X1 Y2 S0 ; Set active low endstops

M558 P8 I1 R0.4 H5 T24000 F200 ; Set Peizo - P probe type, I Invert, R recovery time, H dive hight, T inter-probe-point speeds, F Probing Speed

DWC - Duet control web pages & sorry I should have taken in what you've written...

So I take it, that at the fourth point the probe hits the bed ??

FYI, as it looks like you are still on RRF2, if so, this was my setting for that version (which worked well)

M558 P8 I1 R0.5 H5 T24000 F250 A3 S0.08 ; Set Peizo - P probe type, I Invert, R recovery time, H dive hight, T inter-probe-point speeds, F Probing Speed, 3 Dives , S calculated difference

Thank You

For me, DWC is over blown showing the same info on multiple screens, where a simpler interface would suffice, e.g. the temperature chart being shown on most screens is pointless, as I've never yet altered temperatures during a print run.

No, I don't necessarily think Octoprint\Astrobox would be any better, unless they give repeatable acceptable quality prints, which after all is what the system is intended for, and currently the printer does not provide, hence my desire to at least give them a go...

And exactly the same model, printed using an older Prusai3 Mk2 (all settings the same, apart from printer volume), gives far superior results always

In answer to Ziggy, I always use PrusaSlicer, even though I also have & tried other slicers e.g. Simplify3D, and all running on separate workstations. As for the device trying to drive the printer, I've tried using a Win10 laptop, Pi3B+ and a Rock64, all with no joy.

I've included few pictures of what occurs during a print, as well as my config file etc.

Yes, everything has its own power supply (24v Duet2 etc.)with a common 0v\Ground, no earth loops etc.....

I've tried driving the Duet using an RPi3+\Octoprint & a Win10 with Yat & Octoprint server (a pain to install & get running)

I ask, as I'd really like to be able to actually to use the printer reliably, and would like to drive the hardware directly using something like Octoprint\Astrobox etc. without using the overblown DWC etc.

Currently using the USB connector, there appears to be a timer watchdog that that resets the connection every few minutes or generates an error stating that not enough axes are homed & sending G28 does nothing, and the only way to recover is to reboot the Duet....

Have you tried writing the code direct to the device, via the USB port, using Bossa ??

I've recently had to re-flash mine after accidently hitting the erase button

Silly question, but where are you buying them ?? I've had a couple permanently fail, and even though they were supposedly 'branded' items, I doubt they were as they were a lot cheaper than others.

Also try connecting them to a PC, whether Windows or Linux, & re-formatting them, I've resurrected a few that way....

Hi George,

Thanks for you suggestions. looks like I'll have to put my thinking cap on ....

All my servers have a local domain web server, so I'll have to look at putting something on one of those. I could probably do a simple selection menu, with sub folders for each remote host & dedicated config files so that nothing needs to be entered\saved in the browser....

My system is comprised of multiple printers\cnc machines, sited around the house, all SBC connected, apart from the Duet2 (hopefully will soon be connected to a Pi3).

All are hard wired to a GB network, with all the SBC's running some form of Ubuntu, mainly headless, and Octoprint, apart from the Duet....

I then run a number of Windows 10 workstations & 2019 servers, from which I then run everything else, not only for the 'construction' devices but also remote telescope \ astrophotography systems (another hobby).

So what I'm just after a simple web page, that can quickly show the state of any on-going process of any device on any non headless desktop, without faffing around, configuring each browser for each and any device... The browser in use are IE on the servers (still the only supported on), Edge\Firefox on the Win 10 workstations and Firefox on the ubuntu workstations. e.g. something like this, but even this is over the top, but is 'cleaner' as a quick view of what is happening....

..

Thank you getting closer, at least turning on polling means I can get past the initial config screen, but only for that session, as nothing is saved back to the json config file, including a change to the theme....

And some things aren't working, e.g. the webcam I have working in the DWC is not showing, how to configure separately ? & the height map isn't showing, and my case lights scripts are displayed but they don't work..

But as nothing is saved to the config file, does that mean I will have to re enter the config url for each browser instance I open, on each computer I try & open the UI on ??

Yes the file is in the /sys directory,,,,, If I enter the URL you posted, I get the config file which I can download\edit and I can also edit the file using the normal DWC sys edit tool....

But clicking on 'save' still does nothing, and looking at the json file I see no changes being applied, even if just for a theme change...

These are the class DuiUisettings in the json file, but one thing I noticed is that there are no settings for the local host and config json, is this correct ??

/*
class DueUISettings {
backend_type = "STANDALONE";
duet_debug_polling_enabled = 0;
duet_password = "";
duet_poll_interval_1 = 500;
duet_poll_interval_2 = 0;
duet_poll_interval_3 = 3000;
duet_polling_enabled = 1;
dueui_settings_dont_send_gcode = 0;
dueui_test_mode = 0;
theme = "Sandstone";
}
*/

As requested a picture of settings page (using Firefox)

On selecting a different theme for the page, the theme changes, then subsequently selecting\deselecting any of the 4 'red' buttons, highlights appropriate selections within the inspect window, and the refresh button refreshed the window...

But selecting 'save' appears not to do anything, and 'inspecting' pushing the button also shows no changes.
