DWC/DCS now extremely slow to respond about duetsoftwareframework HOT 11 CLOSED

Possibly related i am seeing these occasionally:
[warn] Restarting transfer because a bad header response was received (0x0001015f)

from duetsoftwareframework.

I think

[warn] Restarting transfer because a bad header response was received (0x0001015f)

has more to do with #22. I see that if I limit the memory to a very low limit and it tries to continue.

Other than that I just tried clicking on a jog button to move the X axis as fast as I possibly can and it worked flawlessly.

how about the temperature change drop down, or the homeall button?

Maybe its an Raspian issue? Looking at the memory usage:
KiB Mem : 948304 total, 68388 free, 220940 used, 658976 buff/cache its not so desperate

P.S. i have terrible lag on any UI button it appears, including jog.

P.P.S it also applies to gcode sent when printing a file.. Looking at M122:

Code buffer space: 1144
SPI speed: 5000000 Hz
Full transfers per second: 0.95

from duetsoftwareframework.

No lag on my side. Sometimes it just fails to finish commands, though, and then the UI just has a spinner somewhere that does not disappear.

Where do you access DWC from? A PC or on a screen connected to the RPi using localhost?

from duetsoftwareframework.

Not printing anything but I get

=== Duet Control Server ===
Duet Control Server v1.0.2.1
Code buffer space: 1024
SPI speed: 1000000 Hz
Full transfers per second: 25.53

over the network normally but its just as laggy on the Pi directly - possibly even more laggy as chromium is now stressing it out!

from duetsoftwareframework.

Are you maybe confusing the lag with #27? It does not update the UI in most cases for me at all. I usually have to reload the page to see any changes. I e.g. just typed G92 X-10 and it showed X to be homed only after page reload.

I had to stop the time on it. :-D I just was able to click the jog button 75 times in 8 seconds with no delay in command execution or (in this case available) UI feedback.

from duetsoftwareframework.

I could track this down to the used SPI/GPIO driver. I am really fed up with the quality of external GPIO libraries for the Pi so I will implement my own driver classes today. Once they are complete, people will be able to use DSF on non-Raspberry boards, too.

Will be fixed in the next version.

Fixed in DCS 1.0.3.1.
