Just a little lost re: upgrading to 3.0 firmware.

[whosrdaddy]

Yes the guide is indeed a bit unclear at times.
the examples are using underscores in the pinnames but the list does not use underscores (ie e0heat vs e0_heat).
I don't have access to my printers now so I don't know what naming convention I ended up using...

[Steve Lynch]

@Dougal1957

yes, I have, or at least I have attempted to, if you see my config above. I'm using the PWM 5 port on the Duex 5. but what to call it? does it need the Exclamation point before it? Does it need the Letter C before it? What does the C mean? "I've been trying to figure that out. I'm also trying to figure out if this new system simplifies the situation by using it's actual name, instead of the "always 1 or 2 off" manner of the old naming convention (example, Pwm 5 on the duex was actually referred to as PWM 7 in the total count).

So for the name of the port, do I have to include all of the aliases? or just the port I'm using? Is duex pwm5 really pwm5? or Heater7? (it says in the list they're shared....

This is where my head wants to explode! I see why this change was made, and I embrace it! I just want so desperately to understand the nomenclature, so I can have that light bulb go on over my head and i can say "I Understand Now!" lol

[Dougal1957]

@Steve-Lynch try changing the BLTouch pin name in the M950 to C"expheater7"

I am not promising but the description of the M950 suggests that.

[Dougal1957]

But having said all this I am sure you can use the Mod pin on the Probe connector to drive it but I am not a BLTouch user so not 100% on that

M950 S0 C"duex.pwm5" ; define GPIO/Servo Pin

That's correct if you have connected the PWM servo input of the BLTouch to output PWM5 on the DueX.

Do the M401 and M402 command deploy and retract the pin?

[Steve Lynch]

No, they do not. I am definitely in PWM5 on the duex, with the orange on the left, red in the center, and brown on the right, as seen in the instructions. My white and black leads are plugged into the "probe" port, to the left of the 50 pin duex ribbon. I'm in the first two pinsfrom left to right. white, then black. the same way It's been set up in 2.5.

[Steve Lynch]

I was a little sketchy on the whole servo pin angle entry below it as well. does that look ok?

[dc42]

What do you have in your deployprobe.g and retractprobe.g files?

[Steve Lynch]

this is deploy:

; generated by RepRapFirmware Configuration Tool v3.1.1 on Tue Jun 09 2020 01:46:51 GMT-0400 (Eastern Daylight Time)
M280 P0 C"duex.pwm5" S10 ; deploy BLTouch

this is retract:

; generated by RepRapFirmware Configuration Tool v3.1.1 on Tue Jun 09 2020 01:46:51 GMT-0400 (Eastern Daylight Time)
M280 P0 C"duex.pwm5" S90 ; retract BLTouch

I tried reaching out to the railcore group, and as it turns out, there are 8 guys who couldn't get it to work, so they went back to 2.5, and one guy who says he can share his config with me, but he doesn't use a BL Touch.

I went back to 2.5 last night so I could print, everything was fine, then I did the configurator again this morning. Still no Joy, though this time, it did add the BL Touch Info.

So I guess I have to stick with this for everyone else, once we get mine right, I'll share the info.

Does anyone have a CoreXY running E3D heater / thermistors, and BL Touch?

If I can at least look at how it's set up, I can model mine after that.

Thanks so much!

C"duex.pwm5"

Remove that from your M280.

The M950 in your config.g creates the servo pin. M280 P0 targets that servo pin.

[Phaedrux]

That's right out of the configurator.

[Steve Lynch]

@Phaedrux
I had it set up just like you just posted, and this is the error I get every time.

"Invalid servo index 0 in M280 Command."

I'm in the port labeled PWM5 on the duex board. This really is PWM5, correct? PWM5 isn't really PWM7 or something like that, right? I'm just trying to figure out why I cannot deploy the probe. Everything try yields some error or another when I try the M401...

That looks correct to me. If you send that command from the console, what response do you get?

Please verify using M115 that you are running firmware 3.1.1.

[Phaedrux]

And you have this exactly in config.g?

The command I wanted you to send from the console was the M950 command that I quoted.

[Steve Lynch]

This is my exact BL Touch Section:

; BLTouch
M950 S0 C"duex.pwm5" ; Define the bltouch servo on duex.pwm5
M558 P9 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

@dc42 Sorry sir... This is what it says:

[dc42]

Looks like you are running RepRapFirmware 2.x then. Send M115 to check.
