@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,

In thermostatic mode, which is what I'd like to use, on startup the fan has a quick burst of full power.

Id' like to stop this quick burst.

It's for an extractor to maintain a set temperature within the enclosure, but I don't want this quick burst on startup. I don't want to completely disable this on the whole board or on all fans, just this one fan.

I've already set the 'B' Blip factor to 0.0, but this doesn't doesn't stop the full power on startup.

Hi All,

Is there a way to disable a fan connected as a thermostatic fan on start-up?

I know this sounds somewhat counter intuitive, but the idea if to have an enclosure fan/extractor fan (thermostatically controlled), to keep the enclosure at a set temperature?

Or would it just be simpler/safer to buy a separate temperature controller?

Hi Guys,

Just looking at power supplies and I have a question regarding the specs of my stepper motors.

This is a Modified Tronxy X5SA Pro CoreXY.

Here is the spec's I've been given from the manufacture;
SL42STH40-1684A-23电机图.pdf

With reading the documents on figuring your power needs you multiply the rated current by rated voltage. 1.7a x 24v in my case = 40.8W

Then add an addition 50% for driver loss and acceleration = 61.2W per motor?

Surly this isn't correct 61w per motor.

There's very little online about these motors either.

That said, I have just found this. Although I can't read Chinese, I understand it mentioning something about 3vdc, which sounds more realistic?

@jay_s_uk @jens55 @Herve_Smith

Yes, Multiple threads from the same person and I thought it was working correctly.
I've had to remove my printer from it's enclosure (as it were), disconnect everything, so I could work inside the enclosure. I needed to quickly print a few items for inside the enclosure before I can put everything back (not realising I need to print anything before removing it all). So I've connected it all back together on my work bench.
The part cooling fan was on 100% and wouldn't turn off, the tool heater couldn't be found, machine reset, all to name a few issues when I switched it on.
I isolated this to my emergency stop button that was basically putting the printer into a constant emergency stop.
Don't ask me why, it just did, when it worked fine before???

Yep following the guide below states to use 3.3v and ioxin, not ioxin and gnd.

I'll give the ioxin and gnd a try tomorrow.

Thanks guys for your advice.

Hi Guys,

I'm trying to wire a NC Emergency stop button, but can't get it working correctly.

I have the NC contacts wired to IO4, to pins 3.3v and io4 In.

Here's the code I've added, but does nothing?

; Emergency Stop
M950 J1 C"io4.in"
M581 P1 T0 S0 R0
M582 T0

What is the correct way to do this please?

Yet more issues with this emergency stop button.

I've had to disconnected everything an move the printer. Just fired it up, and no end of issues.

I've found that this was caused by the Emergency stop button.

I've tested the switch to check it's connected and working.

Connected to the NC terminals of the switch.

Wired to "io4 in"and 3.3v

With the following code. The machine runs as normal without the button press, but when I press the button, nothing happens. It does not switch everting Off?

; Emergency Stop
M950 J1 C"io4.in"
M581 P1 T0 S0 R0
M582 T0

If I invert the code its just in a perpetual emergency stop.

Any ideas?

@deckingman

This looks amazing. Well thought out and neat.

I'm very interested in your electronics/wiring, as I'm just about to start my mod's to my Tronxy X5SA pro (corexy).

Your DC Distrubution panel. Are each sections all connected with a busbar or something, ie the 5 x Red 24v terminals all connected together?

Can you remember what these terminals blocks are (make and model)?

Sorry, but the issue still persists?

I'd just made some changes to my config.g and clicked Run Config File.

If I click Restart MainBoard there's no problem?

@Phaedrux @chrishamm

I've just updated to 3.4.6.

M401 and M402 now work as they should.

When I type M98 P"config.g" I still get the following response and have to manually press stop on the paneldue;
Connection lost, attempting to reconnect...

Maybe this is a bug similar to the following thread;

@Phaedrux

Thank you once again.

This is where it gets a bit silly and one of the reasons for building my own cast tool plate/build plate.

The Tronxy X5SA Pro 330 x 330mm build plate I'm currently using has 2 independant Z Axis motors, left and right centre of the build plate.
It then has 6 bed adjustment screws 3 running along the front and 3 along the back, which fasten and adjust the bed from the bed frame.
The 2 leadscrews are 2mm pitch (confirmed by Tronxy) and the 6 adjustment screws are M3 at I guess 0.5mm pitch.

So its quite a painful experience after I've tinkered with things and have readjust the bed to get it within a reasonable tolerance.
1, I have to level the bed frame to the Y Axis top rails
2, Run a 3x 3 mesh bed probe, roughly where the 3 front and 3 back bed screws are (and along the centre line)
3, Adjust the screws
Repeat 2 & 3 many times (after tinkering or not used for a while)
Run a 12 x 12 mesh bed probe

Once the above is done, and if I'm using the printer the next day for example, I do number 1 with the engineering blocks, then run my Bed Adjustment Screws Macro (which just probes the bed centre and 4 corners), then set the Z offset (this was with the Tronxy inductive Z Probe).
I've not printed yet using the BL Touch.

So yes it's organised chaos.

I also hadn't answered your previous question. On power-up Yes the Z-probe does a deployment and retraction test twice.
