New firmware 1.21RC1 available

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.

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.

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