New firmware 2.0RC5 available

sigxcpu

Thank you for the answer.

I've scanned this thread, but missed that.

Is this a permanent issue or we can expect it to be fixed in the future? I don't know the internals, but I assume that the serialization buffer is small. If it is that, can't you simply generate the JSON on the fly (i.e. streaming)?

Another option is to shrink the JSON. On a machine to machine transfer there is no need to repeat type, name, size, date all the time. They can be abbreviated to t n s d, for example.

LE: now that this started me, I dug in the source code.

I see that the big M122 reply is sent at this size:
Content-Length: 2539

My example reply is:
Content-Length: 1992

My example with shorted field names is 1739 bytes in size, around 250 bytes smaller.

So there are ~550 bytes that could've taken more files to be displayed.

Also the modified times can be encoded as UNIX timestamps instead of formatted, which will reduce that even further, from 21 bytes to 9 bytes per entry.

We can have a parameter in rr_filelist sent by DWC to request short format and implement a list with all the above mentioned optimizations, so things are backward compatible.
I can take a stab at this, without the buffer size part (M122 is big, filelist is small) because I don't know why you've chosen it to be that way.
This will be for a 2.1 release maybe.

I agree that the protocol is too verbose (I didn't design it) and we are discussing how to fix the issue. Unfortunately it won't be fixed in time for the 2.0 release because the master files are needed tomorrow for SD card duplication.

sigxcpu

How do you think this should be integrated?

create a new command like rr_compactfilelist?dir=xxx
add a parameter to existing rr_filelist like rr_filelist?dir=xxx&compact=true

I ran into an issue I have never seen before in the 1 series of firmware. I almost always run prints via Octoprint over the usb serial connection. About 3.5 hours into a print the connection died.

I am running firmware 2.0(RTOS)RC5 (2018-05-22b1).

Here was the error on the Octoprint terminal:

Unexpected error while reading serial port, please consult octoprint.log for details: SerialException: 'device reports readiness to read but returned no data (device disconnected or multiple access on port?)' @ comm.py:_readline:2417

In the DWC console it had this:

g-code buffer 'serial' length overflow

I ran an M122 in the DWC console interface:

I know I am weird to still use Octoprint with a Duet Wifi, but I like the various plugins and record keeping that it provides over the DWC interface. Thanks!

Running FW: 2.0(RTOS)RC5 (2018-05-22b1), DWC: 1.21.1

Tested on small print and no issue occured.
Just one glitch on first print (macro with delta calibration, heat and cooldown) when reloading DWC in browser caused "Emergency STOP". But can't reproduce.

Running 2.0rc5 and dwc121. 1, I have noticed odd behaviour of M122 included in slicer end script. At the end of the print, the M122 report does not appear. The gcode console accepts an M122, but no report. YAT connection accepts M122, and provides a report, but this does not relate to the print, so I guess the original M122 cleared. The DWC console accepts other commands when in the M122 blocked state, and M122 works fine after reset. The effect is seen with S3D and kislicer end scripts.

I just finished a print with a strange message:

Error: G1/G2/G3: intermediate position outside machine limits
Finished printing file Upgrades/Spool_Holder.gcode, print time was 4h 9m

X is now reported as being -253.69

My end code is the following

G10 P0 R-273.15 S-273.15 ;extruder heater off
M140 S-273.15            ;bed heater off
G91                      ;relative positioning
G1 Z+4 X-20 Y+20 F9000   ;move nozzle away from object
G0 S1 X-250              ;move X to the left, so the head is completely out of the way
G90                      ;absolute positioning
G0 Y190 F5000            ;move bed to the front
M84                      ;steppers off

Could it be that the G0 S1 X-250 in contrast to a G1 S1 X-250 F3600 that is used in my homex.g is the problem here? AFAIK G0 and G1 are aliases on a cartesian setup.

This might not be directly related to RC5 but I never had this message before and I have not modified my end code since updating to RC5.

@sigxcpu said in New firmware 2.0RC5 available:

How do you think this should be integrated?

create a new command like rr_compactfilelist?dir=xxx

add a parameter to existing rr_filelist like rr_filelist?dir=xxx&compact=true

The solutions we are looking at are:

DWC to revert to using rr_files instead of rr_filelist.
Extend rr_filelist to take a "skip the first N files" parameter, and in the response to return the value of N that should be used to get the next chunk of the file list, with N=0 meaning the list is complete.

Most likely we will implement #2.

What printer geometry do you have?

That message is new in RC5 but I don't think it should ever be reported except for G1 moves on SCARA printers and G2 or G3 moves on any type of printer. Maybe it was the G1 Z+4 X-20 Y+20 F9000 command that provoked it? What was the head position prior to executing that command?

A G0 S1 move should behave the same as a G0 S1 move, but I haven't actually tested it.

Last movement command in gcode file was
G1 F2250 X16.307 Y159.991 E0.02498 (only followed by a G10 before executing end code)
and Z was at 7.1 at this point.

My limits are

I had canceled a print and then started another using the "Upload and Print" button. As the machine started the print, the controller reset. I can repeat this reliably. This does not appear to be an issue if I manually select a file to print though.

The IDE should need no additional configuration for the RTOS build, except that you need to configure build variable GccPath in the FreeRTOS project just as in the other projects.

Thanks for your report. Sadly I can't tell anything from those diagnostics, they look normal.

I have found a bug in RC5 that could explain some instances of not being able to maintain a reliable network connection. If the firmware times out trying to get information for a file (which is most likely when there are large GCode files and the SD card has a small cluster size), it doesn't close the file. This could result in the firmware running out of file handles. It also explains the report by a user who was unable to delete a GCode file until he restarted the Duet.

I will release RC6 to fix this, probably tomorrow.

Just had an instance where a print finished, I manually uploaded another, then selected it for printing and the controller reset.

I just replaced my mechanical relay, that I previously suspected of putting my controller in a slow state, with an SSR. Strangely, the end.g file did not turn this relay off as it should have when the previous print finished... M42 P7 S0 ; Turn off Vacuum
