Filament monitor not working.

macguyver

@T3P3Tony I'm running a lot of your stuff. I'm also running 3 1HCL expansion boards for closed loop steppers on x,y,and z.

@T3P3Tony So I've done some more of my own troubleshooting. While the measured distance of filament is low the sensor detects and triggers as it should. Eventually the measured distance stops recording. When that happened I cut the filament and it did not detect the lack of filament and continued to print. The number that it freezes at is variable. First time this happened it stopped at 4382.3mm, now it's stopped at 6214.0mm. Below will be a M122 if it helps.

As a possible work around until this is fixed, I am wondering if there is a command to restart the measured distance that I could put in the slicer's layer change Gcode. Disabling and reenabling the filament monitor via M591 S works, but it pauses the print every time it is reenabled.

Last bit of info for the weekend in case it helps in any way. Resetting the measured distance by disabling and reenabling the filament sensor seems to fix this temporarily. It will still eventually stop accumulating measured distance and that number appears to be random. I had it go as high as 43,000mm and as low as 12mm. This happened 12+ times over a 24 hour print.

macguyver

@T3P3Tony @dc42 lost another print this weekend due to this bug. Is there a command I can put in my layer change that will reset the accumulated distance without pausing the job?

dc42

@macguyver are you able to test a new firmware build to see of it resolves the issue? If so, do you have any CAN-connected expansion boards in the machine?

macguyver

@dc42 yes I can try a new fw build. I have lots of can connected boards. 3 1hcl and a tool board.

dc42

@macguyver please try the files at https://www.dropbox.com/scl/fo/tjznycpk7bv7sj71p0ssl/h?rlkey=096p4nvgmigyrb20jj8olg3wu&dl=0. Caution, these have not been through the same level of testing as a beta release. There are partial upgrade notes at https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x-RC#reprapfirmware-350-rc2-changes-since-350-rc1---in-preparation.

macguyver

@dc42 Thank you, i'll try these tonight when I get home and report back any findings!

macguyver

@dc42 The accumulated distance is still stopping randomly, but I am now able to reset it without it pausing the print.

Tinchus

@macguyver well, what I do is execute again the configuration command. I can be done while printing and measured distance is reset to cero, but also calibration data too. But this would do the reset you want, just put the config line on the layer change gcode.
