Stable firmware 2.01 (Duet 2) and 1.22 (Duet 06/085) released
-
so we established there is an issue, it's not the file size because you have a 31MB file.
Lets wait & see what @dc42 thinks about this... -
I Too am on the latest FW and DWC
-
The firmware has has to seek backwards through the file from the end to find the last Z move. With large files this can get very slow because of the way the FAT file system works, especially if the SD card is formatted using a small cluster size. So to prevent DWC timing out, recent firmware versions apply a time limit to this operation.
To speed up access and minimise the chance of reaching the time limit, format the SD card using the largest cluster size you can, which is 64kb for 4Mb cards and smaller (FAT16 format), and 32kb for larger cards (FAT32 format). Send M39 to find the current cluster size.
-
Thanks David, I understand now. It's not a big issue anyway, since I am currently printing non stop, I will try your advice later
-
I consider this to be a bug:
Now that you can upload g-code while you print, if you upload a file with the same name as the file you are printing, the print will switch from the file you were printing to the new file.

I'll add this to the list of things to fix. The firmware already checks for trying to delete a file while it is being printed.
EDIT: I just found it was already on the list, but low priority.
-
Maybe add a warning/question? This helped my last time when I need to add a pause command into a running print.

I just ran
M39
and gotSD card in slot 0: capacity 3.98Gb, free space 3.78Gb, speed 20.00MBytes/sec, cluster size 64kb
so my card is already formatted to the largest possible cluster size (it came this way I never touched it) and still I could reproduce @whosrdaddy's issue. Intersting why it works for @Dougal1957 with an even larger file though.
Just an idea: @Dougal1957 do you still have the stock SD card or do you maybe use a faster one? Also @dc42 do you know more details on the speed of the stock SD card?
-
@wilriker Prob not I go thru cards quite a lot (take them out put them down and lose them lol) M39 gives
SD card in slot 0: capacity 15.93Gb, free space 15.18Gb, speed 20.00MBytes/sec, cluster size 32kb

When uploading a laser file, which could be in excess of 30MB there is a large delay. I keep getting "could not fine end of file error".
For Laser files, the Object Height, Layer Height and Filament Usage are not required or recorded in the file, so the firmware will ever obtain the data. -
@appjaws, what is the exact message you are getting, and when?
-
DWC just sits after the file has been uploaded until it fills each box with N/A.
The firmware is searching for this data when it doesn't need to for laser files.
The "could not find end of file error" appears randomly during printing.
I will see if I can nail the exact conditions laterEdit. The "could not find end of file error" appears when the print starts

This is a screen shot at the end of the Laser print.

Good afternoon,
I do not know if it's my problem, but I've made a couple of impressions with this latest firmware and the latest version of DWC, and it seems that the number of layers does not match the printed layers. My two impressions have finished in 52 of 50 layers
Greetings.
-
it is inconsistent, it seems not to depend on filesize.
for completeness, this is my M39 output:SD card in slot 0: capacity 7.74Gb, free space 6.93Gb, speed 20.00MBytes/sec, cluster size 32kb
I did not have this problem on 1.21 firmware.

Hey,
I just came back somewhere, I wanted to operate the duet with the display just this did not respond well to the commandow, so I wanted to increase the temp but that does not work anymore, this went in firmware 1.21 still normal, this is a known problem
? I like to hear thisthank you in advance
-
sorry is not due to the firmware, but the touch panel does not work anymore, and I have not had it for a long time @dc42 what about warranty?

Do you mean that the display is working, but the panel does not respond to touch? If so then it's most likely the touch panel on the display that is faulty. If you have the non-integrated version, then it's possible but not very likely that the PanelDue controller board has developed a fault.

I have a separate PanelDue controller card,
I used the display yesterday, got the printer on again today, and now half of the touchscreen is working -
