mesh grid compensation crashing dwc

Monster Delta

hi thanks for getting back to me. i am using dwc 1.22.4-b1 and i get the following message................
The connection between the browser and your machine has been interrupted.

Reason: Host unreachable

Please wait while a new connection is being established...

if i refresh the tab i get the page not available error i have to shutdown the printer and close the browser power up the machine and then open the browser again and then dwc will fire up

Phaedrux

Try with the full release of DWC 1.22.4

Ok so I've been revisiting this today. I updated to the full vesion of dwc and it is still doing the same thing, the light next to the wifi chip is solid blue to say its connected but i cant reconnect without restarting both the browser and printer

Press control-shift-J to open the browser debugging console, then see if any exceptions or other errors are reported when the disconnect occurs.

Monster Delta

Hi this is what is shown in the console

Monster Delta

That just continues on and on until i restart the machine and browser

dc42

Thanks.

Is that error message at the very top the first one? If so, that one is normal when loading DWC. But the "connection reset" errors are not normal.
Please send M122 from USB after the problem has occurred, and post the report here.
If you send M552 S-1 followed by M552 S1 (from PanelDue or from USB) to reset and restart the WiFi module, are you able to connect?

Monster Delta

once the dwc disconnects the duet is completely unresponsive to usb also when i connected the panel due it worked ok again no problems but when i disconnected the panel due it went back to playing up

dc42

Please try with RRF 2.02RC4 and DWC 1.22.5 in case it makes a difference. If the problem persists, please post a M122 report taken immediately before you trigger this problem.

Monster Delta

I am already using the latest firmware a dwc i will post the m122 report

Monster Delta

once i start mgc i cant get m122 to work

dc42

What is mgc ?

Please post your config.g file. Also send M557 without parameters and report the response.

I have tried adjusting the mesh grid spacing up to 100mm and various figures inbetween, i tried reloading the config file but neither has worked. I find it really strange that it only works with the panel due plugged in wich seems to be the opposite issue to the post you linked

dc42

@monster-delta, I just wanted to let you know that I haven't forgotten about this issue, but I find it puzzling and right now I am out of ideas

Monster Delta

@dc42 no worries there's no real rush the printer is working fine appart from this issue.

@monster-delta said in mesh grid compensation crashing dwc:

once i start mgc i cant get m122 to work

Do you mean that M122 doesn't even work if you send it from USB?
Please can you temporarily double the mesh spacing to 54.0 and try again. I am wondering whether the fact that you are using the maximum number of points is related to the problem.
