Duet 3 mini 5+ random "pause" while printing

chrishamm

@krohm-koala That's pretty strange, I haven't been able to reproduce it on my machines yet with your G-code file:

Apparently the print settings don't match my machine but there are no blobs or indications for random pauses visible AFAICS. I'll be happy to address this problem as soon as I figure out what exactly is going on.

@chrishamm Clean install done, with the good sd card, problem still here, so i give you my config files, maybe it could be usefull @jay_s_uk can you upload yours too so we can compare if there's "weird" similarities that can cause the bug ?

@chrishamm this is a weird problem, i have a small print that i've done recently where there's 3 circular tower of small diameter and with this the problem is quite frequent. at least, we have eliminate the fact that it can be a sd problem. If you need me to run some other tests, don't hesitate

@krohm-koala we have just released software 3.4.0beta6. I know that @chrishamm has improved the SBC to Duet interface in this release, so I suggest you upgrade to see if the problem has been resolved.

@dc42 Problem still here

@krohm-koala Sorry to hear that, I hope I'll manage to reproduce the culprit next week. @jay_s_uk may provide some further debug details, too, so I can eventually figure out what's going on.

@chrishamm since i've upgrade to 3.4.0b6 i can't upload with prusa slicer, it looks like it have upload on the slicer but print doesn't start and i can't find it on the duet

@krohm-koala I'm happy to report we found the reason for this problem and it will be fixed in the next version. To work-around this problem for now, you can set the HostUpdateInterval to -1 in /opt/dsf/conf/config.json but be aware that this will prevent the network and storage devices in the object model from being updated.

PS: It turns out PrusaSlicer sends G-code requests as application/x-www-form-urlencoded whereas it should be text/plain. I've got a work-around ready for this, too.

@chrishamm Thanks a lot, it's smooth now what's the work-around for prusa slicer please ? if it's an easy one
