Firmware 2.02 Release candidate 3 now available

[frafa]

Hi David,

I test firmware 2.02RC3 on my Scara and DuetWifi
I do not have a Z end stop just your IR Probe
and G28 error on G30
G30 S-1
G30 P0 X0 Y0 Z-99999

Return:
G28
Error: Z probe was not triggered during probing move
Error: G0/G1: insufficient axes homed

My homeall.g (ok on 1.21RC3):

M18 ; Disable all stepper motors (pour desactiver le second bras IMPORTANT !)
G91 ; relative movement
G1 S2 Z4 F250 ; ensure head is clear of the bed

;Move by security to the case or already home !
G1 S2 X10
G1 S2 Y-10

; Home proximal joint
G91
G1 S1 X-200 F2000 ; move proximal joint clockwise by up to 200 degrees until the endstop switch is triggered
G1 S2 X5 ; move proximal joint anticlockwise by 10 degrees
G1 S1 X-20 F300 ; move proximal joint slowly to the endstop switch again
G90 ; absolute movement

; Home distal joint
G91 ; relative movement

G1 S2 Y-5 ; move distal joint anticlockwise by 10 degrees
G1 S1 Y20 F300 ; move distal joint slowly to the endstop switch again
G90 ; absolute movement

;Home Z
G90 ; absolute movement
G30 ; Single Z-Probe

My ZProbe on config.g:

; Z probe
M558 P1 I0 X0 Y0 Z1
G31 Z2.2 P500
M557 X25:265 Y25:265 S80

[Googliola]

@dc42 @claustro
M557 X15:325 Y-15:270 P3 (in config.g)
resulting in
Error: M557: Error: M557 P parameter is no longer supported. Use a bed.g file instead.

Seems like a bug to me. Or what am I missing? (It worked just fine with S parameter, but defining the number of probing points is so much handier...)

I accidentally pressed the tool over the PanelDue instead of the temperature. After that, my 4 hours printing was broken because in the middle of printing the tool T1 with offset and temperature was deselected.

Error message in DWC:
Error: Attempting to extrude with no tool selected.

Such inputs should not be executed in print!!

Ouch.

I completely agree with you that the attempt to change tools should be blocked. However, I think it'd be more appropriate for it to be blocked by DWC and the PanelDue (and not by the duet firmware itself.) Gcode that changes tools in mid-print is completely reasonable for multiple tool machines. For Paneldue, I think this would be a fairly simple change to just check the 'status' before reacting to the tool button.

Edit:

I just submitted pull request #42 for panelduefirmware to address this. I can't help with DWC (but I think it's not quite as easy to deactivate a tool with DWC.)

[dc42]

When an SD card print is in progress and not paused, I think it might make more sense to disable many GCode commands that come from other sources. Not just tool selection but also G32, G29, and all movement commands except baby stepping. This would be done in the main firmware so that it applies to all input streams except the SD card.

Comments?

[Phaedrux]

@dc42 I think that would be a good safe default. I've ruined a few prints myself by accidentally touching the PanelDue during a print.

I still think there is a place for a screen lockout function for the Panel due in addition.

Seeing as you asked - I often change tools mid print so personally I'd be a bit miffed if I couldn't. The usual case is when I've sliced something and forgotten to select the correct tool (colour) for my mixing hot end so the slicer defaults to tool 0. The print starts and as it does the skirt, I realise that it's using the wrong tool so I just select the right one. As it's a mixing hot end, I set the operating and standby temperatures to be all the same in my slicer start code so switching tools doesn't give me any problem. If I couldn't switch tool, I'd have to abort the print, clean the bed and start again, which wouldn't be the end of the world but I prefer it the way it is.

You don't pause before changing tools? Would it be disruptive to pause before changing tools? (I've never worked with a mixing hot end, so I don't know if pausing causes a problem or not.)

I'd be fine disabling many commands (originating from PanelDue or the DWC gcode console) from the firmware if the status was printing and not paused - as long as those commands were available while paused.

Would that impact people who stream gcode from the USB port (such as octoprint)? Telnet? Do you implement something that monitors the current "source" of the gcode stream, and then block commands from all other sources?

[fma]

Please, don't disable commands in firmware ! Sooner or later, someone will need to change something while printing, to make specific stuff. And this is where RRF is great: it allows us to experiment, and make amazing things.

I vote to only disable some critical buttons from DWC/Panel Due, or, better, just add a confirm dialog, so we can still use them. And having the ability to define which buttons we want a confirmation for would be great (not too complicated to do with DWC, maybe more tricky with Panel Due).

[kuhnikuehnast]

Or implement a switch like enable / disable potential "dangerous" commands during print. (like a "child safety lock" )

[Jacotheron]

I think for this specific issue faced above, if the firmware could prevent having no tool selected during a print (in stead of simply preventing a tool change), it might have solved it. Changing tools mid print is sometimes needed and very useful.

Also another vote for the switch to disable/enable these potential dangerous commands, or the confirm dialog. Someone should know what they are doing, when running them.

Correct. That is to say, with a mixing hot end all filaments are loaded all the time. So there is no need to pause between tool changes. I just set the active and standby temperatures the same for all tools in the start gcode. Sometimes, it is necessary to purge between tool changes but not always. It depends on the model and often the purge can be accomplished during infill so that printing with multiple tools (colours) is a continuous process.

[DocTrucker]

@dc42 Previously I suggested that while in the print process that gcode should be encapsulated in another command, sort of like linux 'sudo dosomethingmad'.

Enabling or disabling this behaviour could be set in config and the PanelDue firmware could have a log in and configurable time out to enable the use of dodgy commands mid build.

I'm in the process of setting up a menu system on the 12864 LCD for my freshly acquired Duet Maestro

The video in this tweet https://twitter.com/Greg191134/status/1060312518659358720 illustrates the glitches I'm having with buttons appearing and disappearing.

Also for the horizontal bars, which are an image, the eight pixels on the right are not displayed.

Are these some limitations of the current implementation of the menu system?

[zerspaner_gerd]

Something must be done against the accidental confirmations!

But scary that apparently all existing buttons / commands can be executed in print, what could happen there.

Everyone is responsible for themselves which G M command he sends over the g-code Console Manuel. But the buttons, menus Head Movement should actually be locked at a printing, so rather DWC and PanelDue firmware?

Good point. And if you really have to change something during a print you could just uncheck the child safety button in the Duet Web Control. If you programm these changes in the config.g file it would be pretty difficult to make any changes during a print

Please confirm that you using firmware 2.02RC3. If so, please start a new thread about this issue, and share your menu files.

[Googliola]

@dc42 maybe it's a minor bug, but it does not work as you said. Could you please have a look into it.

I assume you mean this:

I confirm, it's a bug. Will be fixed in 2.02RC4.

Hey @dc42 thanks for implementing the wifi re-connecting functionality in 2.02! (I'm running RC3) I've been doing some testing on the web connectivity...

At first I thought it was working perfectly and it was until...
I switched on my Pi running motionEye (which is normally running 24/7). The moment that the feed came up and started displaying in Duet Web Control the drop outs started immediately exactly.
I never thought the cause of all the problems I'd been having could be the web feed and the Pi just happened to be switched off. Sure enough, deleting the link to the feed in the user interface settings and, boom, the disconnects stopped.

Interestingly I have just put the web feed url back in (same url as I cut it previously to put in clipboard) and I am now not getting drop outs. I will continue to monitor and test this though.... EDIT: after about 5 mins of writing this email we're back in the state where it disconnects and reconnects.

I can open the web feed on a separate browser tab and it continues to feed as expected during the drop outs.

Could there be an issue with taking web feeds and it causing DWC connection drop outs?

My Duet config
Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 2.02RC3(RTOS) (2018-10-17b2)
WiFi Server Version: 1.21
Web Interface Version: 1.22.4-b1

My network config
EE router in house on which my machine connects.
Netgear EX2700 extender in garage on which Duet WiFi and motionEye both connect.

Running Mac OSX Mojave & Google Chrome (Version 70.0.3538.77) but the same thing happens on Safari (Version 12.0.1 (14606.2.104.1.1)) and on my smart phone (Samsung s8+ on Chrome).

note: I work in IT and am pretty confident it is not my network as I work from home and use it constantly without any other issues.

I hope that helps?
