Duet 2 Wifi + BL-Touch doens´t work, no Trigger-Signal

[Phaedrux]

I can't think of anything other than the probe not working.

Perhaps you can find something here:

the clones break easily.
happend to me as well. would not trigger no matter what.
i build a bfptouch in the end.

@Phaedrux Thank you for the link.. helpfull

@Veti yes it seems so as me.
Your bfptouch looks interesting, if you have no functional printer.. no possible to print one.

I ordered an origin BLTouch... and maybe next weeks I see more.
I hope the V 3.0 is much more stable.

[JustD]

I go forward.. temporary I switch to a Z-Switch, to adjust E01 for correct extruding.. done
I calibrate the X,Y,Z-Axis movement.. Works.... done
So my test Cube is 20x20x20.. but the heatbed seems to hot.. I couln´d remove the Object from the headbed... smile
It is as it is placed with superglue.. .. Filament is ABS-neXt from Eins3D.. Wow..

Sorry for my bad english, I´m not a nativ speaker and my last lesson is much years ago.

Try heating the bed up again to soften the plastic and see if it can be pulled off. I find it helpful to use something like glue stick to act as a release agent.

[JustD]

Now also the E1 is running..
WOW I´d never thought before, that so much differences between diverses PFT-supply pipes exist. WOW
In my case.. is 30% smaler inner diamenter.. and so .. at a bowden 3D Printer it´s much more power and pressure neccssary.
Too much for the filament.
I changed these supply pipes.. and all works fine..

I learn every day with this printer.

[JustD]

Glue stick as release agent??..
I´v read often, with glue stick some object have a better grip.. instead of better release.

I try it at first with a much lower bed temperature. but for today.. it´s a long day for me.. it´s finish.
I could remove the Object.. for today.. it´s damaged.. but for the first test..ok

Good result.. first probe is print.. and nearly works good.. the side surface are the best what I print ever.. I´m happy with this..
for the next day´s I wil spend my eye about the top cover.. that not so good..
But this is for my opinion a point of temperatur and speed.

At the Moment I print this with very slow speed and 245°c

[Phaedrux]

Yes the glue stick also helps it stick, but it keeps the plastic from bonding directly to the print surface.

If the bed is removable from the printer, try putting the bed+print in the fridge or freezer to help remove the print from the bed.

[JustD]

Oh, it´s this surface.. and I´m happy with this..

I playing around with diffrent surfaces at my first printer.. Aluminium+ liquid glue, or (i Don´t know the Word in english) Pertinax like elektronik boards... nothing was really good .
Also good conditions are Glass-Surface and it´s really good to remove the objects. But in 350x350x4mm, with 6 little holes.. gmm.. not easy to buy this .. and much expensive.

@justd Try 3DLac if you can get it in your part of the world. https://www.3dlac.com/

Hi, yesterday arrive the new BLTouch V3.0.. and .. works super fine...
But this one, have other dimensions (Length) as the old one.

Whats the best Way to calibrate the BLTouch mechanic?

[JustD]

OK.. is done.. hightmap is saved..

Now it´s working.. .. Now I tune some S3D parameters for different filaments.

Does anyone know the scripts for toolchange at printing time?
For print with 2 different Materials or different colors at one Object. I know, should be two objects in one printingfile a combined object.
What I´m searching for is, the scripts for Simplify 3 D.
Ok, it´s a little offtopic here

[dc42]

You can do the tool changing either in the Duet's own tool change files (see https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Tool_change_files) or in S3D. if you put the commands ni the Duet tool change files, then all S3D needs to generate is a T command to change tool.

[JustD]

Thank you, thats wil help a lot..
But for today I see.. it´s not soo easy to change tool during printing a object.
I try it yesterday maually.. only via WEB-interface.. retract, load.. etc.. and.. I see, I must find out, how much I need to retract for a good and working toll-change.

[JustD]

Whow.. These 3-Way-1Nozzle Header.. needs really 55mm for complete retract.
Puuh.. during a print for my feeling too much.

I see at a manual retract and load a new filament via E2 with a ABS with lower quality.. it could be a problem to change.
After I retract te cheap ABS, I can´t load the white, better ABS.. grr..

So I order a Diamond-Nozzle with 3 E3D and only 15mm retract.
I will see what happens next month.

What i think about:
How is it possible, only with the stock Duet 2 Wifi, to use 3 extruders??

Is that possible or do I need a expasion-Board? (it´s heavy expensive)

[dc42]

The expert on the Diamond hot end is @deckingman on this forum. See his blog at https://somei3deas.wordpress.com/tag/diamond-hot-end/.

It's easiest to drive if you add a DueX2 or DueX5 to your system, although that's not the only way.

Another Question: What are the right setuo in simplify3D for the Duet 2 WiFi??

Here my setup, but I´m not shure if it is right.

What I mean is the Setup in the Process-Setupp FFF the section G-Code at the left side:
x 5D-Firmware

• relative extrusion
  x the G92 E0 parametre
• autonomous Extruder Axis
• extensive M101/M102/M103
  x Firmware support sticky parametre
• use Tool-offset in G-code

Sorry I try to transplate from German.
