New firmware 1.21RC1 available

I notice when I pause and resume, it adds some strange extra move in after running the resume script. It's also writing a resurrect.g, not sure if it's supposed to do that on pause?

It moves back into place, then moves about 2cm out of the way at print height, then moves back.

This is my resume script

; Resume macro file
M83 ; relative extruder moves
G1 R1 X0 Y0 Z2 F6000 ; move to 2mm above resume point
G1 X0 Y0 Z0 R1 ; lower nozzle to resume point
G1 E12 F3600 ; undo the retraction

This is the pause script
; Pause macro file
G91 ; relative moves
M83 ; relative extruder moves
G1 E-12 F3600 ; retract 12mm
G1 X1 ;wipe
G1 Z2 F1200 ; raise nozzle 2mm
G90 ; absolute moves
G1 X0 Y300 F6000 ; move head out of the way of the print

This is video of the unintended move after the head lowers.

Additional information regarding the extruder motor stutter. It's rather random, but about 1/3 of retract/unretract moves exhibits this jerky movement. Its like the interrupt for driving pulses to the motors are lagging. It moves in short 'bursts' but doesn't miss steps. At some rare times the retract move is smooth but extremely slow and returns to full speed when unretracting. I'll try to shoot a little movie clip of the phenomena.

Duet 0.6 board. I haven't tried it out on the Duet WiFi yet as this printer is undergoing a complete hardware makeover right now.

@dc42:

Thanks for you report.

Regarding the printer becoming very slow, I have one other report of this, also on a Duet Ethernet. Next time it happens, please use M111 to enable GCodes, Move and DDA debugging. Then send a movement command. It will echo the gcode, then the move details, then do the move. What I am interested in is where the delay occurs.

My machine just finished a print and since I was sitting by it, I immediately commanded it to turn on relay output after it finished the end.g script. It responded quickly. However a short while after that, I attempted to home the machine and it was slow to respond.

Any idea about the move on resume? Bug or bad script?

Are you sure that isn't a normal printing move? It looks to me that it is printing one full line of the inner perimeter.

Hi,

i have try to update to 1.21RC3… but i have not acomplish.

1- Download [c]DuetWiFiServer.bin[/c] from https://github.com/dc42/RepRapFirmware/tree/dev/EdgeRelease
2- Upload by web interface
3- When finish upload, star flashing, and at the end, in DWI, can see [c]WiFi Server Version: 1.21RC1[/c]
** This seems ok** NEXT
3- Download [c]DuetWiFiFirmare.bin[/c]from https://github.com/dc42/RepRapFirmware/tree/dev/EdgeRelease
4- Upload by web interface
5- But… when finish upload, can read a message: [c]M997 S0 Error: M997: In-application programming binary "iap4e.bin" not found
[/c]

Where i can find [c]iap4e.bin[/c]?
Where i have to upload?
The file [c]iap4e.bin[/c] depends on the firmware you have installed? (In this moment: 1.20.1RC2 (2018-01-01))

Edit: I have read Wiki and [c]iap4e.bin[/c] is in https://www.duet3d.com/wiki/Where_to_get_Duet_firmware_and_tools

I am having slow upload speeds via the DWC. Via FTP it works as expected but over the web control it goes to like 20 K/s speeds.

Thanks for your feedback. Can you provide a Wireshark trace of a HTTP upload?

Definitely sure. I've seen it move outside the border of the print and back. I can try to capture a better video if you'd like?

Sure: https://www.dropbox.com/s/4x20l1f4m59r12y/dbot.cap.pcapng?dl=0

But sems to be a lot of window errors and retransmissions. That doesn't happen with port 21/ftp.

any ETA for the next stable release ?

dc42

Next stable release will be 2 to 3 weeks from now. There will be at least one more RC first, probably two.
