@jay_s_uk

Thank you.

I've also just noticed something in my config.g that I thick, with looking in the dictionary ,is causing conflict. In M950 shouldn't my bed heater be H0 (H zero), rather than T0 (T zero), and my nozzle be T0 (T zero) instead of T1?

So far so good with using the ethernet, and without fully commissioning I ran a G32 once with no problems, no running a second scan for unknown reasons and no network error.
Without further testing I can't say if this was linked to the previous board, found to have an sd card issue or not.

Sorry "I thick" , * I think.

@norder

Thank you for your detailed guidance. I've tinkered with your example code, but not had a good chance to test it (I've got a lot on at the minuet).
I have had to omit the G92 Z0 in the homez as this resets the the settings previously entered for the trigger height in config.g.
I appreciate you have different z probes, and what you've sent above is an example. Thank you, It does help a lot.

I'll try and get time to test/tinker/play tomorrow, but it may be at the weekend until I get good chance to do so.

Dizzwold.

@Dizzwold

Yep, a clone Toolboard and clone Hemera.

I'm disabled, and on UK benefits due to health, so after purchasing the original and authentic Duet3 6HC, I couldn't afford the authentic Toolboard or Hemera, so please don't hold that against me. I will over time manage to afford these as original products.

@mandragora @Norder @jay_s_uk @deckingman ,

Thank you guy's, these are all very informative and valued information. This give me a lot to consider, and decide upon which way to go with this.

I've added a photo below. Sorry, I should have done this in first post so you all had a better understanding.

@Norder I already have a second floor/partition, but this directly above the "built-in" soundproof chamber. I was planning on using this as my filament storage. When I say built-in, it's breeze blocks and plaster. I've already had to strap one side with an addition joist in the loft to take the extra weight of the TecSound soundproofing and soundproof plasterboard as this was unsupported and above a stair case (it did have small notched joist, but not enough for the addition weight).

I'll have to take some temperature reading in the partition above. I suppose I could have it in an enclosure (in the above partition), and have a fan and duct in the timber above the door if needed. Then run cables to the paneldue, that will hopefully sit to the right of the door on the cable trunking.

Thank you again guy's for your time and advice.

@droftarts

Hi Ian,

Thank you again for your help and input.

I figured the above out in the end (or I hope I have).

Here is my example from the terminal. Maybe this will help others.

@norder

Thank you again for your help, I'm very grateful.

I'll have a look at the home all and homez files.

@norder said in NPN Inductive Z Probe:

This is not necessary because the G29 command that does the MeshBedLeveling has already calculated this offset.

I'd been advised in a previous thread that this wasn't calculated and had to allow for this myself, but was also told that the probe would just report "Unreachable", and continue.

I'll go and look at the files and see what I can do.

@jay_s_uk

Seriously, a big Thank you for your help @jay_s_uk .

I'm really grateful for your time and guidance.

Hi All,

So it looks like I'm swaying toward the Duet 3 Mini 5 as few have commented on. This way I can also upgrade ‘if and when’ needed.

It looks like I'll have to wait a few weeks before any more Duet 3 Mini 5's are ready, No Pressure David. LOL

I am most grateful for everyone's input and advice.

No doubt I'll be back again with yet more questions, but for now I think I have a bit of reading to do, to familiarise myself better with the Duet system.

Also any more comments and / or suggestions are very welcome.

Thank you,

Dizzwold.

Hi Guys,

I had just written a reply stating that I still hadn't quite figured it out, but I think I've kind-of grasp both your ideas, although they need tidying up they both work;

Thank you both again for your help, I'm really grateful. You have the patience of saint's.

@jay_s_uk

The thought I had was to use 6mm deep magnet and leave 2mm on top, but with your failure it maybe best just to go with the large PEI sheet.

As @deckingman has previously commented and written-up on, and currently uses, you can always use a glass plate on top.

@dc42 @oliof

Hi Guys,

Thank you for your replies and confirming.

Very grateful.

Dizzwold.

@oliof

Okay thank you for your advice.

The part in the documents that states;

"sqrt(2)"

Does this mean, the square root of 2, ie 1.41421356237, ?

Regards,

Darren.

Hi Guys,

I'm considering setting up StallGuard on a couple of Nema23 motors using TMC2160 drivers.

In the documents it states;
Hmin = full_steps_per_rev * rated_current * actual_current/(sqrt(2) * pi * rated_holding_torque)

Is "sqrt(2)" the square root of 2, ie 1.41421356237, ?
Then x (multiplied) by pi,then x (multiplied) by holding torque?

What's the best way to determine the actual motor current?
I think this is where the Duet3 will come in, or would I just be better off buying the TMC2160 evaluation kit?

I'd be very grateful for your input, more so as it is rather Off-Topic/Forum.

@T3P3Tony @jay_s_uk

Hi Guys,

Thank you for that.

Ah, okay, so I'm taking the information for the sensor from the S2 part of the config.g rather than the actual board input connection "Temp1".
Edit.
Which I beleieve means changing;
M118 S{"Message to Show: " ^ sensors.analog[1].lastReading ^ " C"} L1
to
M118 S{"Temp 2: " ^ sensors.analog[2].lastReading ^ " C"} L1
Thank you again for your help and advice.

Dizzwold.

@jay_s_uk

Okay, thank you.

Hmm, It's working but seems to be reading the wrong sensor. Temp1, which is what it is reading and documenting, is this T1 in my config.g?
It's basically reading the nozzle temp in the log at around 203˚C. I have the sensor I want to read in-between the fan and the heatsink on my Matrix extruder, "(he chamber heater below). In the graph it shows as around 40 ish ˚C ?

I have the following in my config.g on my 6HC board;

The very bottom "sensor" temp1 chamber heater is what I'd like to read.

But hey, I'm printing again and with my cast toolplate with pei sheet and mains heater. Hip-Hip-Hooray
It is printing so sweet.
It's not fully trammed yet, as I can't afford the new framework yet to enable doing so, but it's the best I can do for now.

Hi Guys,

Thank you for your direction I'll give them a try.

I'd already promised previously to look into the BtnCMD, but I really just haven't had the time. This is actually going to be my first print with the Cast Toolplate I've been on about for the last 2 if not 3 years.

Daemon.g;
I know very little about this, but with a quick goggle I understand it's to do with running a clock from the MCU in the background.
So this has to be called "daemon.g in the /sys directory?
Can you have more than one daemon.g in the /sys directory as I've seen it mentioned before with something else I read, and would you just number them?
daemon1.g
daemon2.g
etc

I don't even know if your need more than one to be fair, just asking?

Hi Guys,

I appreciate this is an old thread and I'd like to do something similar, but not sure I fully understand it.

What I would like to do is take temperature readings every 20 seconds (or so), from a thermistor on (temp1), for the duration of a print and save them to a log/file or something like the heightmap.csv to look over at a later date. I only really need the temperatures.

I've tried putting both the suggested lines above in Config.g but all that seamed to do when I clicked save was immediately creat the file in /sys then start then stop a log.

Can I ask for your advice of what should actually go where or if there's another method to use?

Hi Guys,

I'm relevantly new to the Duet 3 boards (a year or 2), and have a friend looking into purchasing a Laser Engraver mostly for etching images on wood.
He's had a bit of a bad experience with trying to purchase an American or Canadian unit, so it crossed my mind that between myself and my friend, we could build one use a duet board.

I've had a little look around on the forum regarding laser engraving with the Duet series of boards, but there doesn't seem to be a great deal of people on the forum regarding this.

Would a Duet be a good choice of board for controlling a laser engraver?

Hi Guys,

This is following on from the end of my thread "Cast Toolplate Bed Progress ?", the last 8 posts within.
https://forum.duet3d.com/topic/34461/cast-toolplate-bed-progress/34?_=1704187570604

I have a Duet 6HC with a NC Emergency Stop Mushroom type button switch. When I press the emergency stop button, it stops everything as is should, but when I disengage the switch I have to manually click the RESET MACHINE radio button on DWC on my computer screen.

I've tried various methods and combinations using the triggers, but nothing eliminates having to physically click the radio button on my computer screen.
The triggers and the switch have been tested and all function correctly.

I now believe it's something in the actual program in C++;

From line 144-219 is regarding the M112 command and how it is reset. I think?
Lines 188, 189, 205, 206 prevent a perpetual reset?

DWC on Computer Screen RESET MACHiNE from Emergency Stop
https://forum.duet3d.com/topic/34675/dwc-on-computer-screen-reset-machine-from-emergency-stop

@deckingman
Going back to the toolplate bed, I'm going to use the following connector mounted to the bed frame. The idea being that I can disconnect the cables so I can remove the bed (the printer will be in a cupboard, tight on space, so less weight with moving the frame in and out).

Being that this is now a Mains 240Vac bed heater, and I have spare pins on the connector, I'm thinking on the grounds of safety and running some kind of signal loop (5/12v on a relay), so when the connector is disconnected, the break in the (5/12v) signal loop will disconnect the mains with the relay (if I've not already done so), so there is no loose Live Mains cable floating around.
At the moment I have a1 SSR controlling the 240Vac mains bed switched directly by the 24v O/P from the Duet 6HC.
So I'm looking for ideas.
Should I use a mechanical relay in series with the mains from the SSR, or is there a good chance this will weld closed?
Use another SSR, again in series with the switched mains;
