Solved Ooznest Workbee Z Touch Plate Support with RRF3.2.2
-
@dc42 Am I right to assume that these commands in this form (with a NO configuration) should produce some movement even if nothing was connected to estop0? i.e. we can eliminated any physical problems with the touch plate hardware?

Yes, unless there is an error in the commands that I haven't spotted yet.

I have just tested M585 on a Duet 3 running firmware 3.3beta2 and it appears to work correctly. However, I have noticed a number of defects in the M585 code, for example it doesn't report an error if the Z probe is already triggered. So I will fix those, as well as trying to reproduce your configuration on a Duet WiFi.
-
Thanks for testing this at your end. I have flashed RRFW3.3beta2 onto my Duet2 and rerun the macro as posted above. No change for me unfortunately - no error messages and no apparent motion.
I also removed the '!' and re-ran the macro expecting this would trigger the 'probe already triggered error' that you mention (do I understand correctly that 3.3beta2 has fixed this M585 bug?). On my machine this version also produces no errors or movement.
-
@dc42 I wonder if you have any further suggestions on this issue? I'm really keen to work with you to get it sorted, but without anybody seeming able to identify anything obvious in the macro, no error messages to indicate any problem on the Duet, but with a total failure of movement and a rather core function needed for every CNC toolpath I'm unsure where to go next..? Should I just write-off this approach and go with a G38 based route like @Yveske, or are there more things I can try to help you diagnose the issue?
I was really hoping to move onto replacement Vue modules so that Ooznest customers (and others) can make use of the latest firmware 3.xx improvements (which I need for consistent laser support) and the excellent DWC-CNC work of @Sindarius (to hopefully provide a longer-term maintainable RRF3 compatible UI) - but at the moment I'm dead in the water. I obviously cannot expect customers to update their installations if I can't reproduce the existing capabilities they currently have under RRF2 & Ryan's original DWC.
Many thanks in advance. E

I'll try and see where we're at with M585. Thanks for your patience.

@edwardp, please try the unofficial 3.3beta2+1 build at https://www.dropbox.com/sh/6203euyyobllic5/AABTHIbn7F_maK9p-oy7vq3Ea?dl=0. It's compatible with DWC for 3.3beta2.
-
Thanks guys - @dc42 I'll flash the new firmware this weekend and report back.

On uploading and installing Duet2CombinedFirmware.bin from your zip I get the following error:
Error: M997: In-application programming binary "0:/firmware/Duet2_SDiap32_WiFiEth.bin" not foundDo I need this additional file from somewhere, it is not included in the zip above?

You can find that file in the 3.3beta1 and 3.2.2 releases on github.

OK - thanks @dc42. I've re-uploaded alongside the WifiEth.bin from the RRF3.2.2Beta2 and confirmed the new firmware looks good:
Board: Duet 2 Ethernet (2Ethernet) Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.3beta2+1 (2021-03-19)The probe test macros, exactly as above, continues to give no error or motion I'm afraid.
One aspect of my set-up I should be clear about is I am running the DWC-CNC-CNC02-3.2.0-RC1 (built from the tagged branch on https://github.com/Duet3D/DWC-CNC) from my local machine and connecting to the Duet2 over ethernet. I'm using this UI to upload the firmware patches and trigger the macro. This is our test machine, so it has been upgraded from RRF2 in quite a few incremental steps now. Could any of these things be a source of this problem?
Can I just also formally confirm that my macro (as posted above) does run on the test rigs you have at your end - I'm not sure we have quite stated that explicitly so thought I should check?

OK - machine up and running.
My probe z macros is now as follows:
M563 P0 S"ZProbe" ; Define a 'fake' tool (is this necessary?) T0 ; set the fake tool M400 ; make sure we've finished any other movements M558 K3 P5 C"!e0stop" ; configure probe 3 as switch connected to e0stop M585 Z10 F600 P3 S1 ; probe 'forward' in Z 10mm or until Probe 3 triggers ; Set the current workplane offset relative to this current position, backed-off 10mm ; in Z to allow for touch plate thickness G10 L20 Z10I do not appear to have 'deployprobe.g' or 'retractprobe.g' in the system files (or macros) but I did have a 'probe.g', which definitely looks out of date so I have renamed that in case it was problematic.
Macro, as posted, produces no errors, response or movement. For the avoidance of doubt, the machine homes, jogs in all axis, moves under G0/G1 etc. with no apparent issues.
I have the same problems with my workbee
-
@dc42 perhaps you could post a 'canonical' macro sample showing the commands as you intend them to be used and that you have verified at your end? If there is a typo/mistake in my macro this would help us to flush it out.
The set-up I (and I think many Workbee customers) have is simple and because of Ooznest's documentation: https://learn.ooznest.co.uk/Guide/Assembling+Your+Original+WorkBee+XYZ+Touch+Probe/61they should be configured pretty consistently. At this point I just need to reproduce the simplest Z probe (Step 8 ) under firmware 3.2.2 - which is needed before any CNC toolpath can be run.
The macro needs to drive the tool down in Z until contact with plate is made (wiring as per the link - plate is essentially an NO switch) and set Z0 in the current work-space to be this position, plus the thickness of the plate.
I cannot emphasise enough how core this functionality is. The Duet under RFW3.xx is not, in practical terms, usable as a CNC controller without it. It has been over a month since I raised this problem...
-
(@scrhall thanks for checking this too, by the way, much appreciated)
-
@edwardp I had to revert back to firmware 2.0.5 due to this very reason. Though I enjoyed using some of the added functionality in RRF3.2.2 with the DWC-CNC from @Sindarius , the lack of a probing wizard like Ooznest's made me go back to Workbee Control.
-
@chimaeragh I'm going to stick with RRF 3.??, but I really hope that @Sindarius manages to find the time to develop a plug-in that works in the same way. There must be quite a few of us that are craving this option
-
@hagrid it is on my list, just been side tracked with some other efforts at the moment.

Hey I use this code and it works as desired
M400 ; make sure we've finished any other movements M558 K0 P5 F100 C"!e1stop" M563 P0 S"ZProbe" T0 ; set the fake tool M585 Z10 F600 P0 S1 ; probe 'forward' in Z 10mm or until Probe 3 triggers G10 L20 Z19.5 ;Set Tool Offset to 19.5mm thickness of the touch plate ;raise the dirll for 5mm for the second run G91 ; relative positioning G1 Z+5 F1000 ; go back a few mm G90 ;absolute positioning M585 Z10 F100 P0 S1 ; probe 'forward' in Z 10mm or until Probe 3 triggers G10 L20 Z19.5 ;Set Tool Offset to 19.5mm thickness of the touch plate ;raise the dirll for 20mm G91 ; relative positioning G1 Z+20.5 F1000 ; go back for 20mm G90 ;absolute positioningBut maybe I discovered a bug. If you leave out the first G10 command, the code behaves confusing. After the first pass, the z-axis run down in the ground for maybe 20mm and then perform the second probing. The raise for 5mm don`t seems to be performed. Maybe someone else can reproduce that.

@sindarius No worries. Good things are worth waiting for

I use this macro, i found it on the forum. its working for now
; Z Probing macro M400 ; wait for current movement to finish M291 P"Make sure the probe is connected and the Endmill is on top of the probe" R"Warning" S3 ; warning message G91 ; set relative position G30 S-1 M400 G10 L20 Z19.1 ; set Z offset to 19.1 G1 Z10 M291 P"Probing complete on the CURRENT WCS. Please remove probe." R"Success" S1 ; screen message```
