Resolved Print hangs
-
Finally getting prints, looking like I had the config wrong. Id tried to take the figures used in marlin and translate them to RepRapFirmware. Strange there were no errors as such. Still not got reliable prints yet. But it's not crashing
-
I am glad you solved it. The only odd thing I can see in your config.g file is the zero jerk speed for the Z axis in the M566 command. I've never tried using a value of zero, so I am wondering whether rounding errors could make the lookahead mechanism keep recalculating to try to meet it. What value are you using now?

Spoke to early, froze again halfway through a 50mm test tower

I'll upload a little later, but starting to think my config errors maybe just disguising a hardware issue. Just not sure how I can be certain. It's only the controller I've changed.

I am inclined to agree. I'm also wondering whether it is time for us to swap your Duet WiFi. However, I would like you to do one more thing. I will shortly release firmware 1.17dev8 and this includes a report of the last software reset code in the M122 report, which previously wasn't working on the Duet WiFi. So please update your firmware to 1.17dev8 later today, do a print, and assuming it fails again, run M122, check that the "Last reset" cause is again software and the reset time corresponds to when the print stopped, and extract the "Last software reset code…" line.

Will do thanks

Just updated and run a test job. I may have been a little zealous in declaring the last failure. I'm used to the job finishing and parking the print head to one side, where as it doesn't look like the firmware does that for you. So when I came back to my tower, the head was sat at the top, as if it had crashed.. I'm still not getting very good print out put maybe down to configuration rather than faults.
BTW, really appreciate your help.
-
To park the head when the print finished, add appropriate moving and/or homing commands at the end of your slicer end gcode, just before the M0 at the end. Alternatively, just put M0 in your slicer end gcode and define the shutdown sequence in /sys/stop.g.

Many thanks, I believe my original resetting issues have been resolved. I'm still trying to get a print out of the machine, as my use of the manufacturers Marlin settings, plus a possible extruder issue has caused me some problems. Once i get over this hurdle in the next few days, I will play with my setting to help find the original cause. It does sound like its probably that zero jerk speed for the Z axis in the M566 command.
