RepRapFirmware 3.0beta 11 released

Danal

Just for a data point: A conventional microswitch as Z-Probe works fine.

Board: Duet 3 version v0.6 (MB6HC)
Firmware: RepRapFirmware for Duet 3 v0.6 3.0beta11 (2019-10-22b1)

G0 X152.5 Y42 H1 F10000
G30 P0 X152.5 Y42 Z-99999   ; probe near back leadscrew
G0 X295 Y300 H1 F10000
G30 P1 X295 Y300 Z-99999    ; probe near front left leadscrew
G0 X5 Y300 H1 F10000
G30 P2 X5 Y300 Z-99999 S3   ; probe near front right leadscrew and calibrate 3 motors
G1 X0 Y0 F10000

Probe config:

M558 P5 C"io3.in" H5 A5 T6000  S0.02               

            ; Z probe - Set the height of the bed.  Combined with content of bed.g, levels bed. 
            ; P5 = Switch, NC
            ; C = Input Connector
            ; H10 - dive height
            ; A1 = Number of times to probe each point. 
            ; T5000 Travel speed between probe points. 
            ; S0.02 Tolerance when probing multiple times. Two readings inside this window and we move on.

config

M558 P9 C"zprobe.in" H5 F120 T3000 A2 ; FW v3 BLTouch connected to Z probe IN pin
M950 S0 C"exp.heater3"                ; FW v3 create servo/gpio 
G31 P500 X35 Y0 Z2.2                  ; set Z probe trigger value, offset and trigger height

I removed the probe and tried to short gnd and zprobe.in (duet2eth board) and that did not detect it neither

maybe "zprobe.in" was renamed?

G31 ; nothing connected to zprobe.in
Current reading 250, threshold 500, trigger height 2.20, offsets X35.0 Y0.0

G31 ; me holding a screwdriver shorting zprobe.in to gnd
Current reading 0, threshold 500, trigger height 2.20, offsets X35.0 Y0.0

this does not look ok, should I invert something or .. afaik BLtouch is open drain pulling output to gnd on trigger so my screwdriver should of triggered it ?!

@dc42 Is there a release notes document, what is new or changed?

No, because this is a beta and so much has been changed. You can look through the github commit logs in branch v3-dev if you want all the details. But the main improvements are:

Reduced RAM usage on Duet WiFi and Duet Maestro
Ported the fixes that are in 2.04RC4 (which are documented in the usual whatsnew file)
Endstop switches attached to expansion boards are working in some configurations
RPM readings from 4-pin fans connected to expansion boards are now available
Added support for G38 (thanks Manuel)
Extended M122 report from expansion boards
Added DotStar LED support on Duet 3 main board
Include spindle speeds in restore points
Expansion board firmware can be update from an attached SBC
Include laser power in the status information returned to DWC
Added mDNS support to the Duet Ethernet and Duet Maestro (thanks chrishamm)
Added self-check of firmware CRC at startup

Was I dreaming or there was a way to upload web files to the sd cards too? Weird, had to remove the SD cards to put new DWC there

You were not dreaming, you just upload the Duet Web Control .zip file through the Upload System Files button.

Thanks, I think you've found a bug. Setting the G31 P parameter to less than 250 (e.g. 100) may be a workaround.

@dc42 so I just rename DuetWebControl-SD-2.04.zip to DuetWebControl.zip and upload to same place where I upload config.g and Duet2CombinedFirmware.bin and it will automagically fix everything, thanks will try

You don't even need to rename it, just uploading it as-is should work.

G31 ; bltouch attached
Current reading 0, threshold 10, trigger height 3.50, offsets X-35.0 Y0.0

I doubt I can get readout on trigger as it lasts too short, could hookup scope if it would help but I unplugged the zprobe.in cable (so that would be the 250 we seen earlier) during G30 move and it did not trigger

if there's anything else I can do to debug lemme know

dc42

Send G31 P100. Position the BLTouch well able the bed and send G30. Push the pin up before it reaches the bed and the downward motion should stop. If it doesn't, you can cut the power before it reaches the bed.

If the reading is 250 with nothing connected, I expect the BLTouch to give that reading when triggered too.

A Former User

tried that, didn't help, if you look at the last copy/paste from console threshold is 10, I tried 200, 100, 50 and 10 same issue, never triggers, I even disconnected the cable during G30 move (assuming long 250 read will happen) but nothing bed just keep raising

dc42

Thanks for trying. I'll bench test a BLTouch with this firmware tomorrow.

dc42

@smece, which model of Duet are you running RRF3 on?

A Former User

duet2eth, iirc 1.0.2 was on the board

dc42

Thanks. I found the problem, ir affects type 8 (unfiltered digital) and 9 (BLTouch) Z probes. The reading when triggered is 250 instead of 1000. So setting the G31 P parameter to less than 250 should fix it. The machine with a Duet WiFi that I used for testing has a type 8 probe (Smart Effector) but the G31 P parameter is set to 100. So that's why I didn't experience the problem.

sorry no 1.2 was on the small ethernet board that I lost so I got a replacement from aliexpress, no clue if any version is on the board itself, will try to check but not easy to get to it now

No need, I've found the reason.

A Former User

cool, but I'm not triggering with a 100 neither

lemme try again with new config.g uploaded and restarted

A Former User

don't work I'm back to 3b10 (works ok with 3b10)

Added DotStar LED support on Duet 3 main board

Any documentation on this yet?

Disregard that last - looked through the code and found it in the gcode documentation under:
