BL-Touch and the Duex 5
-
Please help me out.. any hints for Checks.. or solutions?
-
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?
-
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.

@justd If this is how you have the motors connected...........,
M569 P0 S0 ; X
M569 P1 S0 ; Y
M569 P3 S0 ; E0 (E1)
M569 P4 S0 ; E1 (E2)
M569 P5 S0 ; Z1/U
M569 P6 S0 ; Z2 V
M569 P7 S0 ; Z3 W
M569 P8 S0 ; E2....then your mapping should look like this
M584 X0 Y1 Z5:6:7 U5 V6 W7 E3:4:8

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.
"G28 ZError: Z probe already triggered at start of probing move
Error: G0/G1: insufficient axes homed"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.
Thats the relevant Config.g and Deploy.g/retract.g

Is there any Jumper to push/remove?
Why does the BLTouch don´t have Power? (LED is lighten)

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

@Phaedrux. No.. the BLTouch is absolute without any function
Now I have this..

Error: Homing failed"That error is likely because you haven't moved the probe into position before doing the G30.
You need something like this
; Homez.g G90 ; Make sure we are in absolute mode G1 X150 Y150 F8000 ; move probe to bed center. Adjust to make the probe be in the center of the bed. Note that X and Y must be homed first. G30 ; Do a single probe to home our Z axis G1 Z10 ; Rapidly move the Z axis to Z=10 G1 X0 Y0 ; return to home position. Adjust as needed.I don't think it matters if the heater unbinding comes before or after as long as it is unbound when the probe is called into action. I've seen people do both.
If the probe doesn't respond at all and appears to be dead that means that either the wiring is incorrect or damaged, or the probe is dead.
Can you temporarily setup the BLTouch without the Duex? Just to see if you can get it working that way to prove if the probe is dead or alive. It may also help to verify the wiring.
Can you post a photo of how exactly it is wired?
-
I have an spare BLTouch.. and for testing I connected directly
-
Did it work?
-
No.. not..
I still get this Errormessage" G28 Z
Error: Z probe already triggered at start of probing move
Error: Homing failed"I think it´s not a Problem of homing.. ..
For my viepoint it is a point at the PWM-Channel ..-- What I say.. after I connect the DUEX, the BLTouch never have the Light on.... in normal mode..I search at the Wiki.. but I see nothing.. to set a jumper. or so..
Also I try.. to switch to Heater 5.. or 3.. so.. Heater 3 is on PWM1 (right?)
Where is heater 5 assigned... to wich PWM Channel? -
@justd it saying that it is already triggered makes me think the probe signal needs to be inverted.
Does the web interface indicate 0 or 1000?
Can you try adding I1 to M558?
If that doesn't work tomorrow I'll try to duplicate your exact setup myself on the test bench.
-
Does the BLTouch run its self test when you power on the Duet? If it doesn't then perhaps it's not getting 5V power.
-
@Phaedrux: Web-Interface show´s 1000
But.. If I test your suggestion.. with i1 at M558.. the Value at WEB-interface is 0
@DC42: No selftest at power on, no Light.. nothing.... The original in the Mashine.. and the spare ... no function.
I try to messure with a mulltimeter.. the 5V.. at the DUEX.. no 5V.. no 3.3V.Thats what I mean.. is there any Jumper who should be set up?
-
@DC42 at a DUEX5 is there always 5V power at the PWM´s?
Or only if the Chanel is called?I checked now.. the general Power at the DUEX... I use the GPIO-Pin.. GND - 5V and 3.3V.. it´s all OK.. 5V and 3.3V are OK at this point.
But If I messure between GND (GPIO) and 5V at any PWM-Channel.. I get only 0.1VHmm.. any Idea whats going on there?
OH.. I check the Board-Layout.. and see.. the Jumpers at the Endstop-Voltage-Select is at 3.3V set.
Is it save for the Board and the BLTouch, if I switch it to 5V?My origin BLT who´s in the printer, is the newest on.. (normaly with 3.3V & plastic-pin), but the spare is a little older with Alu-pin and 5V.
But I´m wondering, that at the 5V-Pin nothing is to messure at the PWM-channel.. egual wich Channel....hmm.
-
No Ideas.. no hints for me?
-
New Info´s.. I found something out..
I read this Thread..
https://forum.duet3d.com/topic/10978/bltouch-isn-t-working-after-change-to-duex-5and test it at my configuration...
And I see..
If I start my Z-Axis for Probing.. my Heater 6 is going on (the LED).. hmm.. But What PWM is this Heater corresponding?I changed my Config.g to this
M307 H7 A-1 C-1 D-1 ; Disable heater 7 to free up PWM channel 5 on the Duex board.
M307 H6 A-1 C-1 D-1 ; Disable heater 7 to free up PWM channel x on the Duex board.Restart and I see.. no light goes on.. at Heater 6.. and If I start Homing Z, the Z-Axis go´s up.. to 0.. but.. the BLTouch have no light.. and no Pin-Down.. so it´s clear.. Z-Axis never stop..
There is still no light on at the BLTouch.. hmm..Now my question:
- How can I see, Wich Heater corresponding wich what PWM-Channel?
- and how can I check this with G-Codes?
- At what time-step does the 5V-Pin have 5V?
Ups .. strange. very strange!
After I try something with the Parameters and Heaters...
from M558 P5 H7 F500 T9000 X0 Y0 Z1:U1:V1:W1 I1
to M558 P5 H5 F500 T9000 X0 Y0 Z1:U1:V1:W1
or M558 P5 H7 F500 T9000 X0 Y0 Z1:U1:V1:W1 I1
and M558 P9 H7 F500 T9000 X0 Y0 Z1:U1:V1:W1
and back to M558 P5 H7 F500 T9000 X0 Y0 Z1:U1:V1:W1 I1Is not the same reaction as before...
Now .. the heater LED is on, If I try to start a Probe... but the BLTouch-LED is off.. and no deploy... .. means no pin down or selftest.. nothing.He Guy´s.. please help me.. I´m stucking.. with this one Point.. and I have no Idea at the moment.

and back to M558 P5 H7 F500 T9000 X0 Y0 Z1:U1:V1:W1 I1The M558 P and H values have nothing to do with the servo and heater pins.
M558 P is the probe type. BLtouch should use P9.
M558 H is the dive height for the probe to use when probing. 5 to 10mm is normal.M307 H7 targets the heater 7 pin, and would mean the M208 servo command would use P7.
