BL-Touch and the Duex 5

JustD

I try something around.. and testing if Heater 3 & PWM1 is better..
But I get this Message if I start the Alarm Release + Pin Up-Macro

Same Result as bevore... the BL-Touch do nothing.. no error-message

wonder if you have an older probe that is 5v only and you are connecting to a 3.3v set of pins for the probe. I used a resistor in order to reduce the voltage slightly

JustD

Oh no.. it´s a brand new origin Probe..

But the Cabeling is from the China-Probe.. and they doenst working..
Is that a Problem?..
I will check ist.. and remove the resistor.

But before I change to a DUEX5, this works with the same new origin probe.

JustD

I have check it.. without Resistor.. no differences... still no function.. hmm

What I also see.. if the X or Y a little far from 0-Point and start homing x / Y .. thats a little curous.

normaly . the Z-Axis have a short movement aroubd 10mm down, before homing X/Y .
My front left leadscrew (1) is running as long as X or Y is moving to the Homing-Point.
The Leadscrew (2/3) do what they should.... go 10mm.. and stop at self.

My question, is it better to switch from the origin Z to another driver (maybe one at the duex)??

JustD

strange.. I´m wondering..
I thougt about.. why my BLTouch have no power.. it seems so. (No LED is on)

I check with my Multimeter and I messure nothing at the duex PWM1 - PWM 5 hmmm..
I double check the two connectors of the Endstops at the Duet.. E0 & E1... and .. oh wondering.. both has power on.. 3,3V to Ground. !
Why the Hell this Ports and not at the Duex?

I thought about the flat-Cable wich connect the Duet with the DUEX.. maybe not OK? Hmm, I think it´s ok, in order to the two Z-drives at driver 6 & 7 are working normal..

Another Test to the extruders shows.. ohh. something goes really wrong!
Instead of any extruder.. folloing situation:
E0 = no reaction..nothing
E1 = the front left Z (U) is flatering not moving
E2 = the rear middle Z (V) is flatering not moving

Hmm.. I thing I have a bigger Problem at my config.g and maybe other files.

I Thought I´m near at btrue´s wiki for 3 Z-Axis & BLTouch
https://betrue3d.dk/bltouch-on-duet-wifi-configuratio-and-usage/#configuring

Additional I check the Btrue´s blog for the BLTouch.. and I see, I have the newest Version of the origin Antclabs BLTouch with the plastic Pin.. and.. 3,3V !!

So my question: Is it rigth to connect the BLTouch with the PWM- connector completle.. incl. the 5V??
Or is it better and correct, to use in this case, the 3,3V vom the Z-Probe Connector from the Duet-Board?

What I also see.. at the WEB-Interface.. is the value of Z-Probe .. allways at 1000.. hmm.

JustD

Push.. no Idea?

Phaedrux

What is the PCB revision of the Duet? You can see the version number on the PCB itself. If you have a v1.03 or v1.04 board, you don't have to worry about 3.3v versus 5v.

The web interface shows 1000 most of the time because the trigger time is very short before the pin retracts, so it's not easy to catch it changing.

JustD

It´s an rev. v1.04
Thank you for this... but I´m stucking with:

my 3 Z-Axis & the 3 Extruders..
the BLTouch.. without any function

I play somthing around with different drivers for teh Z-Axis.. and BL-Touch.. and my last version of Config.g is this.. but don´t wirking right.

I don´t know if it´s really right to have U,V And W.. or not...
Or ist it usefull, to all Z-Axis at the duet (5-7) and no use of the original Z?? I dont know

Nobody can show me really the connection between Heater and PWM.Channels as a Table..(not Pin-#)

I´m sorry.. I´m not a programmer.. so it´s possible I dont know.. what anybody knows.. who can write programs for ... 3D printers...
for the Moment I´m at the end of my Knowledge.. but I want to understand what I do.

Phaedrux

@justd said in BL-Touch and the Duex 5:

M669 K2 Z3 ; switch to CoreXZ mode and multiply motor movements by 3 for the Z axis

Is this a CoreXY or CoreXZ?

I'm not sure what part you're getting stuck on for connecting the BLTouch.
https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Duet_2_WiFi_Ethernet_with_Duex_2_or_Duex_5_expansion_board

Have you tested the probe using this? https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe

JustD

uups.. yes.. this is one of my test and play around..

It´s an Core XY Printer and I actually delete this line. and use the Line above as CoreXY

Thats what I mean with.. "1. my 3 Z-Axis & the 3 Extruders.."
"Another Test to the extruders shows.. ohh. something goes really wrong!
Instead of any extruder.. following situation If I try to extrude (if the Nozzle is hot enough):
E0 extrude= no reaction..nothing
E1 extrude= the front left Z (U) is flatering not moving
E2 extrude= the rear middle Z (V) is flatering not moving

Yes I know this two Links.. and I tested it... Thats what I describe.. I can´t test the Deploy or retract, if the BL-Touch doesn´t working correctly.. means .. the normal LED (red in my).. is not lighting.
Nothing.. so you can do no function test.
I checkt the Cabeling twice and more.. messure from the connector up to the connector at the BLTouch... it´s ok.
I messure the Output of the board.. nothing to messure.. = no output.. I describe it above.

JustD

Additional some information.. maybe.. who knows what one of the problems.

How can I check the DUEX-Board.. for correct function or is it enogh, if the Z-drivers working?

JustD

Please help me out.. any hints for Checks.. or solutions?

Phaedrux

Sorry, but I'm having a hard time following what the issue is at this point. Can you restate the problem as clearly as possible?

JustD

The Issue is..

the BLTouch doesn´t work .. nothing.. no light.. no function (check on E3/E5/E7, all the same connected with DUEX5)
the three Extruder don´t work... instead of the Extruder working... Z-Axis (connected over DUEX5)wobble/vibrating .. . one Z-Axis in order of one Extruder... (E0 [Duet-E0]->Z1[Duet-Z] /E1 [Duet-E1]=Z2 [DUEX-Dr6] / E2 [DUEX-Dr8]=z3 [DUEX-Dr7]) to each corresponding Z-Axis.

....then your mapping should look like this

JustD

Hi Ian, big thank you.... thats the problem with the extruders..!!
One Problem solved..
Next the BLTouch.. I will check it later...

Now I´m checked the BLTouch again and again.. Check wiring.. and setup as Betrue to it.

If I try to Homing Z, I get this Message.

Sometimes.. for a very short while.. the Value of the Z-Probe at the WEB-interface depends on 875 and switch quickly back to 1000.

Is there any Jumper to push/remove?

Why does the BLTouch don´t have Power? (LED is lighten)

Phaedrux

@justd said in BL-Touch and the Duex 5:

Error: G0/G1: insufficient axes homed"

https://duet3d.dozuki.com/Wiki/FAQ#Section_I_get_this_error_message_Error_G0_G1_insufficient_axes_homed

You'll need to modify your homing files to add S2 to any G1 moves that attempt to move an axis before it is homed.

Can you post your homing files please?

M558 P5
Please change to P9 to use the BLTouch probe type.

When you first power on the printer does the BLTouch pop the pin in and out?

samlogan87

Not sure if this matters at all but should the

M307 H7 A-1 C-1 D-1 ; Disable heater 7 to free up PWM channel 5 on the Duex board.

come before or after the

M558 P5 H7 F500 T9000 X0 Y0 Z1:U1:V1:W1 ; Set Z probe type 9 to bltouch (P5 as Betrue3D) and the heater (7) height + speeds (+ B1)

or does it not matter. Currently it is after.
