Duet Stops mid print

Phaedrux

MANY parameters must be exactly right

Like wall thickness not being less than nozzle width?

Re factory files, thank goodness the industry appears to have settled on .3MF finally.

Danal

One wall, right at, or slightly less than, nozzle. Also printed somewhat hot as compared to most printing, so 'current' extrusion melts into 'prior' layer a little bit. PLA at 230 or 240, things like that.

Here's my latest. Extra 550, modeled at 74" wingspan. Plane is about as big as I am. Baseball cap for scale. Haven't flown it yet.

Have you somehow solved this problem of blocking?, I can not so fix this problem..

BlueDust

@Fedekossel1
Yes, it was resolved.
Run M122 and share your report. That would be the easiest way to tell if you are having the same problem we had.

Fedekossel1

@BlueDust
I tried to contact you on twitter, I ran all the procedures you listed, but I couldn't fix

How did you solve it? I also had microsteps at 256, I took them to 16 interpolated to 256, nothing changed, I also formatted the sd and did tests with other 3 sd, it never solved

@Fedekossel1 said in Duet Stops mid print:

=== Move ===
Hiccups: 363416

The hiccup count could be the issue. Using x256 microstepping and having moves faster than the step rate can handle is usually the cause. Using x16 microstepping with interpolation enabled is the solution.

I suggest you start a new thread with your issue. Include your config.g and your M122 output as well.

BlueDust

@Fedekossel1
It appears you may have the same problem as I did with Hiccups and using 256 microstepping.
@Phaedrux helped me fix it. I would follow his advice to help you too.

Good luck!

BlueDust

@Fedekossel1
My Twitter name does not have anything to do with BlueDust as it was already taken. Not sure who you reached out to.

Fedekossel1

I put microsteps at 16 interpolation 256, it still gives me the same problem

Fedekossel1

@BlueDust Did you solve only by changing the microsteps to 16?

BlueDust

@Fedekossel1
Did you update your Motor Steps after you changed it to x16 microstepping?

Per @Phaedrux comment, you should start a new thread, and share your config.g and copy of M122. ( I know you already shared it here, but makes more sense to keep it all together to make it easier to troubleshoot on a new thread).

And yes, changing to x16 microstepping fixed the issue for me. You should make sure to share a new M122 on the new thread after you updating your microstepping to see if you still have a high hiccup count. It was the high hiccup count that caused the issue. It was just 256 microstepping that caused the high hiccup count.
Also, In my case I was printing for over a year before this issue showed itself. I am not sure if it was updated build, or some other changes that made it finally cause problems during a print.

@BlueDust This M122 that I posted is already with microsteps, and updated steps to 16 interpolation 256, I will do a new discussion. Thank you
