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

Thank You

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

Is there any way to easily customise the DWC pages, without reverting to additional HTTP pages etc ??

I especially want to get rid of the ridiculous/superfluous three boxes at the top of every screen, two which are effectively displaying the same information !!

I suppose I'll just have to accept that DWC is crap in the usability stakes, and use it for configuration only, its a pity that there also isn't a simple control interface...

Other than that, I would probably have to dump the board & go for something else.

@Phaedrux

I don't have a spare Pi @ the mo, but I do have a Rock64 / Rock64Pro spare both running Mate, so will the Duet SBC software run on them ??

@jay_s_uk

I suppose it comes down to what the Voron recommendations were, also I originally tried a Duet2 ethernet (not on this 'Voron' but a previous iteration), in non SBC mode, which was an abject failure, so I was hoping that a Duet3-SBC, would be better....

@wdenker

I don't know if will help, but here's my motor configs & mappings

; Configure Drives

M569 P0.1 S1 ; physical drive 0.0 goes forwards - A
M569 P0.0 S1 ; physical drive 0.1 goes forwards - B
M569 P0.2 S0 ; physical drive 0.0 goes backwards - Z0
M569 P0.3 S1 ; physical drive 0.1 goes forwards - Z1
M569 P0.4 S0 ; physical drive 0.2 goes backwards - Z2
M569 P0.5 S1 ; physical drive 0.3 goes forwards - Z3

M584 Y0.1
M584 Z0.2:0.3:0.4:0.5
M584 E1.0 ; set drive mapping E (extruder on 3HC)

@wdenker Why 2 sets of drive mappings (lines 19 & 29) ??

@gloomyandy
no hardware changes, & just the normal software updates pre & post the problems ...

@gloomyandy
yes it used to work fine, and even now it can still produce some great prints !! but it also wastes filament & time when it just stops at some point during a print

@chrishamm

no motor cables come anywhere near the SPI connection, or any other cables, apart from the case fans, which come on/off at the start and end, of a print.

All 0v lines are bonded to earth, I don't believe the problem is environmentally connected, as I have multiples printers running concurrently, with no problems

@chrishamm

Hi Chris,

Yes everything is fully earth bonded, and I've also replaced the interconnections....

Warning: SPI connection has been reset
Warning: Lost connection to Duet (Timeout while waiting for transfer ready pin)
Warning: Lost connection to Duet (SPI connection reset because the number of maximum retries has been exceeded)

M122.txt Errors.txt
config.g.txt

I've been having a number of print failures with the above errors, but usually after a successful print (the same object), where the print just stops (all motors off) and the heaters are all switched off, but he SBC still shows the active temperatures....

To recover the machine I have to go through a full power recycle.

I've checked all connections, power supplies etc. and all good, so any ideas on what I can check for, before I try enabling diagnostic mode ??

As I said, I'm using Edge, that is already set for dark theme, there are no configurations settings for these pages ....

So it's not possible to undo this rubbish??

BTW, for me, even this page is virtually unreadable, unless I can't find the settings to be able to set a 'dark' theme...
