everything is basicly standard from the configurator tool.

I removed the bltouch from my m3d quad and the one from my CR-10 Max including the cables.

but now after a complete weekend trying i gave up.

[jay_s_uk]

@jl-p is your bltouch really 100mm away from your probe in X and Y?
Your homing files look ok.

[JL-P]

@jay_s_uk no I tried something's. I though it was the location where it should probe because my bed start at 17. From the end stop

I also had problems with the BLTouch on exp.heater3.
I then connected exp.heater7 and since then everything is OK.
Somewhere in the depths of this forum or the Duet instructions I read something that could cause problems with exp.heater3.
Since it was all a long time ago, I can't tell you the reason for this and I just tried to find this info again... but without success.

If exp.heater7 is not yet occupied, it would be worth a test to reconnect the cable from exp.heater3 to exp.heater7 and to adapt the config.g.

Ich hatte auch Probleme mit dem BLTouch an exp.heater3.
Ich habe dann exp.heater7 angeschlossen und seitdem ist alles OK.
Irgendwo in den Tiefen dieses Forums oder der Duet Anleitungen habe ich mal etwas gelesen das es bei exp.heater3 zu Problemen kommen kann.
Da es alles sehr lange her ist, kann ich den Grund dafür nicht nennen und ich habe gerade versucht diese Info wieder zu finden... aber ohne Erfolg.

Wenn exp.heater7 noch nicht belegt ist, wäre es ein Test wert das Kabel von exp.heater3 auf exp.heater7 umzustecken und die config.g anzupassen.

[Phaedrux]

From your files it all looks ok, but you're saying when you send G30 the probe doesn't deploy? Where are your deployprobe.g and retractprobe.g files located? Where are your homing files located? They should be in the sys folder along side config.g. In the past I've seen someone have similar issues because the files they were editing were located in the macros folder, and the files that were actually being used were in sys.

@norder Thx that did the trick.

Stil no idea why the other one isnt working because the default deployment works fine.

Thx for your help

[Norder]

@jl-p said in Duet 2 and BL Touch:

Thx for your help

very gladly.

I invested another 30 minutes this morning to find this information to prefer the Heater7 in certain cases.
Unfortunately I couldn't find the info again.

The info is also a few years old and is therefore more likely to be found on the dozuki server than on the duet3d server.

It's just too long ago to remember exactly.
I'm also a bit older (grandpa twice)

Maybe @dc42 knows more about why you should use Heater7 instead of Heater3 for the BLTouch in certain cases?
It had nothing to do with an expansion board though as I don't have one and the Heater7 info concerned me.
There was also no RRF3 for the Duet Wifi at the time.

It's brain terror when you can't think of certain things and you know roughly where they are... but you can't find them. Grrrr

Nice that your printer is working again.

@norder I'm not sure if there was ever an issue with using heater 3! I have tested it many times, and never found an issue. The only mistake I have seen repeatedly, because the picture showing the connections isn't that great, was that users didn't connect to the heater 3 pin but to the pin above. It can look like the pin the yellow wire connects to is on the top row of pins, when it is actually the bottom row, in the picture below.

@droftarts when moving back to heater 3 everything works also.

No idea what happened.

Thx all

That's a possibility I thought of at first too, but then I realized why I don't use Heater3 for my BLTouch.

In my case, I have always checked the Board-Diagram for every cable that I have connected to the Duet over the course of time.
Back then... yes, it's been a few years... my BLTouch on Heater3 didn't work.
Then I leave this info and switched to Heater7 and everything worked as requested.
I rule out 99.9% that I took the wrong pin at the time, because I checked it very often when it wasn't working.

Presumably every duet has a soul or a life of its own... for some like that for others like that !?

I hope that someone finds this info text or can confirm it... otherwise people still think I'm crazy or a storyteller. LOL

Das ist eine Möglichkeit an die ich auch zuerst dachte, aber dann fiel mir ein warum ich Heater3 nicht für meinen BLTouch nutze.

Ich in meinem Fall habe bei jedem Kabel welches ich im laufe der Zeit an den Duet angeschlossen habe, immer auch das Board-Diagram zur Kontrolle genommen.
Damals... ja es ist schon einige Jahre her... funktionierte mein BLTouch an Heater3 nicht.
Dann laß ich diese Info und wechselte auf Heater7 und alles funktionierte wie gewünscht.
Das ich zu der Zeit einen falschen Pin genommen habe, schließe ich zu 99,9% aus, denn ich habe dieses sehr oft kontrolliert in der Zeit wo es nicht funktionierte.

Vermutlich hat jedes Duet eine Seele bzw ein Eigenleben... bei der einen so bei der anderen so !?

Ich hoffe das irgend jemand diesen Infotext findet oder es bestätigen kann... sonst denken die Leute noch ich wäre verrückt oder ein Märchenerzähler. LOL
