G29 does not deploy BL Touch (Duet Wifi 1.02)

[Coded Games]

So I have an ancient Duet Wifi v1.02 that I am using with a DBot CoreXY 3D printer.

I have the BL touch wired up to heater 3 and have homing working perfectly fine. I updated homez.g to deploy the probe as below:

G1 X150 Y100 ; center
M280 P3 S90 I1 ; reset probe
M280 P3 S10 I1 ; deploy probe
G30
G90 ; absolute positioning 
G1 Z20 F4000
M280 P3 S90 I1 ; reset probe 

Unfortunately I do not know how to program the probe to deploy when doing G29. I have updated deployprobe.g and retractprobe.g so that the M401 and M402 commands work. But I do not know where to go from there. Since this hardware is so old it is difficult to find documentation about it, and I'm not sure if it can be updated to more up to date firmware (I really don't care too much about updating, I'd be happy to just get it working).

But anyway here is my entire config.g if there is something important in here. Any help is really appreciated.

@Coded-Games you can update the firmware from RRF2 to RRF3 quite happily on that board so I would suggest you do that.
I would have a read through here https://docs.duet3d.com/en/User_manual/RepRapFirmware/Migration_RRF2_to_RRF3
The easiest route is to probably generate a new config from scratch using the config tool and then adapt it to match your previous one

[droftarts]

@Coded-Games I don’t see an M557 command to define the probe grid in your config.g, which you need. See https://docs.duet3d.com/User_manual/Reference/Gcodes#m557-set-z-probe-point-or-define-probing-grid

What firmware version are you running? Send M115 and post the response. it’s possible your firmware is so old mesh bed compensation is not supported, which was introduced with v1.17.

As @jay_s_uk says, all Duet 2 WiFi/Ethernet boards are still supported in the latest firmware release. I have a white PCB pre-production Duet WiFi (about 7 years old) that runs v3.4.5 happily!

@droftarts Firmware version is currently 1.18.1

I don't have M557 defined in config.g, but instead it's in my slicer start gcode:

; Mesh bed level S = spacing before was 50 set to 80 for less
M561
M557 X20:280 Y20:180 S80 
G29

Previously I had used a Precision Piezo sensor for mesh bed level, which worked OK. But now when I try to use a BL touch I can't figure out where I'm supposed to define how the probe deploys and retracts

[droftarts]

@Coded-Games l can't quite remember for firmware that old if you need to deploy the probe before G29, and retract after. I would guess that you do. You can probably update to v2.05.1 (from https://github.com/Duet3D/RepRapFirmware/releases/tag/2.05.1) without having to change your config.g, and then the deploy and retract are automatic, so you can remove the M280 commands from homing Z.

Ian

[droftarts]

@Coded-Games Checking the release notes, firmware v1.21 added proper support for BLTouch:

A separate Z probe type (P9 in M558) is now used for BLTouch and compatible Z probes. When this is selected, the deployprobe.g macro is run just before each probing move, and retractprobe.g is run every time the probe triggers, or at the end of the probing move if it doesn't trigger

https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-1.x-&-2.x#version-121

There was also a couple of bug fixes/improvements in v2.01:

When using a bltouch, between probe points the pin retracted, deployed and retracted again
When the Z probe type is set to 9 for BLTouch, the probe output is no longer filtered, for faster response

https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-1.x-&-2.x#version-201-duet-2-series-and-122-duet-06085

I'd advise updating to 2.05.1 if you don't want the hassle of updating to the latest.

@droftarts Well deploying the probe before doing mesh bed leveling was the solution, and a fairly obvious one that I should have thought of lol.

Unfortunately I broke my cardinal rule of never updating anything and decided to try updating to v2. I downloaded the zip, put it in the web interface, left for a minute and came back to see that the web interface was disconnected. And I have not been able to connect ever after restarting the printer. Luckily I was able to take the SD card out and backup my config files, but I am still unable to connect to the printer.

So I started trying the fallback techniques, downloaded Pronterface and discovered it does not open at all on MacOS 13, it only supports MacOS 11 and 12. YAT also does not exist for MacOS. Now I'm really stuck, I'm not sure what there is I can do

[droftarts]

@Coded-Games use SerialTools or CoolTerm (better than SerialTools but not on the App Store) for serial console. See https://docs.duet3d.com/en/How_to_guides/Getting_connected/Getting_connected_to_your_Duet#h-3-connect-to-duet

Sorry, I forgot that there was bit a change after v18.1:

If you are updating a Duet 2 WiFi from RRF 1.18.2 or earlier, you will also need to manually update the WiFi firmware via USB or PanelDue. See 'Updating WiFi firmware' instructions below. And you will need to unzip the Duet Web Control zip file into a folder called 'www' on the SD card. See SD card for the current SD card structure.

See the ‘updating from 1.x or 2.x’ tab here: https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware#updating-without-firmware-erase

@droftarts So good news and bad news. I ended up installing Windows in Bootcamp since it appears that every piece of software intended for MacOS is current broken. But once I used Windows I got YAT working and was able to update the firmware to 2.05 and get the web interface working (yay).

But I have some new issues. First being that I can no longer access the web interface using duetwifi.local, it appears I can only access it with the IP.

Alongside that, my config is not right for v2 as it is not letting me home any axis, whenever I try homing one it saying that it is unable to home, because there is insufficient axis homed. So I'll need to figure out how to fix that one

[jay_s_uk]

@Coded-Games want to post your current config?
i still think you're best off going to RRF3 and starting from a clean config from the config tool. We'll all be much quicker to help you with RRF3 than RRF2 as RRF3 came out 2 1/2 years ago so we've all forgotten the old syntax

@Coded-Games said in G29 does not deploy BL Touch (Duet Wifi 1.02):

@droftarts So good news and bad news. I ended up installing Windows in Bootcamp since it appears that every piece of software intended for MacOS is current broken.

I use SerialTools and Coolterm on a M2 MacBook Pro on Ventura. SerialTools is a bit fussy about how you type your input (see https://forum.duet3d.com/post/295706). Coolterm works well, though I usually have it set to Options > Terminal > 'Line mode' and turn on local echo, which sends your command line when you press return, rather than character by character.

But once I used Windows I got YAT working and was able to update the firmware to 2.05 and get the web interface working (yay).

Result. But your poor Mac...

But I have some new issues. First being that I can no longer access the web interface using duetwifi.local, it appears I can only access it with the IP.

mdns is supported on all versions of RRF, for Duet 2 WiFi. See https://docs.duet3d.com/en/User_manual/Machine_configuration/Networking#a-note-about-mdns-local-network-discovery
I can't remember if there is a default name with early versions of RRF, if you're not setting it with M550. Send M550 on it's own to see what the name is set to, or add it to your config.g with the name of your choice.

Alongside that, my config is not right for v2 as it is not letting me home any axis, whenever I try homing one it saying that it is unable to home, because there is insufficient axis homed. So I'll need to figure out how to fix that one

Share your config.g and homeall.g files, we'll get it fixed.

@droftarts Sorry for taking nearly a month to respond. Here is my config.g and homeall.g. As a reminder I was having an issue where when I click home all it says that insufficient axis are homed after upgrading to RRP firmware 2

this move should be a G1 H2 move as the Z axis isn't homed yet

actually, looking at your home all none of them are homing moves. they should include H1 for homing moves and H2 for unhomed moves so this file in its current state just won't work

YOu'll need to finish defining all of the drivers in M584, and the M584 command needs to be moved higher up in the file. Like right above the M350 command.
