BL TOUCH NOT WORKING.

[oldironjunkie]

@droftarts there is a jumper between pins marked "5V INT" and "5V AUX" . the header is between the endstop E2-E6 headers and the thermistor E2-E6 headers

[oldironjunkie]

@droftarts I also checked the voltage manuall with a meter and I have 4.96V dc

[droftarts]

@oldironjunkie Can you post pictures of how it is wired now?
Can you send M98 P"config.g" and post the response from the console?

Edit: check the continuity of each of the wires, to make sure all of them are making a connection.

@droftarts Thanks for the response. I id find a bad connection in the tiny 5 pin factory connection on the BL touch. I fixed it by replacing the harnes with a known good one. Rechecked all and it is ok. The probe now expends and retracts with the M401 and M402 commands as it should. I did the calibration set up and I can home all axis. @ questions.How do I get to home the X and Y at the endstops in th upper right corner (where it is now) but I cannot get the z to home to the pin unless I run a G30 from the console. Also at the same time I would like to probe the z in the center of the bed (A150 and Y150) as this is where most of my prints start. Below are my homeall.g file and homez.g files. I only added the commands I need. Not sure what I need to add or comment out. Also once I get it al working correctly where do I enter the offset from the Bl touch to the nozzle. It is a consistent .59. Sorry about the questions but I am completely at a loss at this time.

@oldironjunkie 2 questions

1. why are your macros called extendpin.g and not deployprobe.g? Likewise for retractpin.g and retractprobe.g...
2. Why are you not using M401/M402 but M98 P"deployprobe.g" and M98 P"retractprobe.g"?

@oliof I was using those names beacause that is what I was sent by a friend of mine. It has changes since. I will post the final files once it is done, working and tested. I am in the process of doing that now but unfortunatly life just gets in the way.

[oliof]

@Herve_Smith M401/M402 means the firmware properly tracks whether the probe is active or not. The canonical macro names to configure these G-Codes is retractprobe.g/deployprobe.g because this was implemented before BLTouch was a thing. So its not just a question of using an aesthetically pleasing or logically right name. And in a thread called "BLTOUCH NOT WORKING" I am asking the OP -- not you -- if there is a reason for them deviating from these canonical ways.

I hope that helps you understand why I am asking the questions I am asking.

[oliof]

@oldironjunkie life getting in the way is what happens to all of it, no worries. I would suggest using the canonical names for those macros and using M401/M402 to rule out any weird misses from mismatching macros, names and firmware expectations.

@droftarts I finally got it working. I had a bad factor BL touch harness to begin with (I have a replacement coming). Before I found out that I messed with everything and got everything out of wack. I should have followed instructions and approached things logically. I now have a bed level height file, homing works great including the Z axis and my first and second prints came out great. I still have to mess with pressure advance (I just installed a new extruder) and dial in the Z height. Thanks to all that helped I really appreciate that. As for the final files here they are.

Haha, I am the pedantic one. Sure (-: Have a nice day, Herve.

[droftarts]

@oldironjunkie Great, glad you got it going! I had been over your config and wiring a number of times, which made me think it was a faulty connection somewhere. A few notes:

If you're homing to the back right, your prints will come out rotated 180 degrees. Generally the origin is at the front left of the machine, so a positive X move moves the nozzle to the right, and a positive Y move moves the nozzle away from the front (or bed towards the front if you have a bed that moves in Y). Yours is moving the other way, which is not really a problem, just so long as you are aware of this. You can change this if you want; let me know and I'll show you where to make changes.

You spotted that it should be G30, not G30 S-1, in your homing files.

Setting the probe as M558 P9 means that the firmware knows it needs to deploy and retract the probe. You don't need to tell it to do it, either with 'deployprobe.g' or 'retractprobe.g' (these are the macros names used, any others will be ignored) or M401/M402. When you sent G30 from the console, it deployed, probed, and retracted without the need to run the other macros and commands, right?

You found how to set the probe offset, using G31. For more details, see https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_testing

You found how to move the nozzle to the centre of the bed. However, because you have put this directly after the homing moves, moves are still in relative mode. Add G90 before your G1 centring move to switch back to absolute positioning, ie

...
G1 H1 X-302 Y-302 F180  ; move slowly to X and Y axis endstops once more (second pass)
G90                     ; absolute positioning
G1 X150 Y150 F5000      ; move to centre
G30 

There is an odd bit in your config; you have defined four extruder drivers, but they are all the same drive. And then set the parameters for them in the subsequent gcodes:

M584 X0 Y1 Z2 E4:4:4:4                                           ; set drive mapping

M203 X4000.00 Y4000.00 Z1500.00 E4000.00:4000.00:4000.00:4000.00 ;set maximum speeds (mm/min) 
M201 X1000.00 Y1000.00 Z350.00 E600.00:600.00:600.00:600.00      ; set accelerations (mm/s^2) 
M906 X1000 Y1000 Z1000 E800:800:800:800 I50                      ; set motor currents (mA) and motor idle factor in per cent 

You are also using the second of these in your single tool:

M563 P1 D1 H2 F0                      ; define tool 1

D1 is the second extruder drive; D0 is the first. Unless you're going to add the extra extruders/tools (you do have a Duex after all) I'd clean this up by removing the drives you aren't using, and the extra parameters you have put in the other gcodes. eg:

M584 X0 Y1 Z2 E4                                      ; set drive mapping    
M350 X16 Y16 Z16 E8 I1                                     ; configure microstepping with interpolation
M92 X79.68 Y79.44 Z400.00 E454.00             ; set steps per mm
M566 X900.00 Y900.00 Z900.00 E1600.00    ; set maximum instantaneous speed changes (mm/min)

M201 X1000.00 Y1000.00 Z350.00 E600.00      ; set accelerations (mm/s^2) 
M906 X1000 Y1000 Z1000 E800 I50                      ; set motor currents (mA) and motor idle factor in per cent 

;Tools
M563 P1 D0 H2 F0                      ; define tool 1

You currently have pressure advance set on D0, while the tool is using D1, so your pressure advance value isn't doing anything.

Hope that helps!

@Herve_Smith Thanks! I'm going to steal that and post it each time, as 'the ultimate BLTouch troubleshooting steps'!

[oldironjunkie]

@droftarts I will add the G90 and change the pressure advance setting to the correct tool. The reason I am not using the 0 drive is that ithe driver was fried by my bad extruder motor. I had to switch drives once I got the motor replaced. Thanks for all the help
