Experience with print-mode: "one at a time"

Recommended Posts

Posted · Experience with print-mode: "one at a time"

Dear Ultimaker-Community,

I've repeatedly had problems with blocked printing nozzles during long-lasting print jobs which I did over the week-end. Using the "print all at once"-mode this meant, that all the parts not finished when the nozzle got blocked, were scarp.

I am thinking about trying the "one at a time"-mode not to loose all parts in case the nozzle gets blocked after some time. Has anyone had problems with this print-mode? - More specifically: Has anyone had problems with the print-head colliding with parts already printed or does the buildplate always lower correctly so that the print-head does not collide with the parts already printed? Does one have to position the parts in a certain order (back to front or vice versa)

Thanks in advance for every tip and hint! :-)

Thanks,

Frank

p.s.: It sounds like a ridiculous question, but I've once had the case that the glass plate was dislocated after a print job with quite a (plastic) mess on it after the print-head apparently collided with the parts already printed. I didn't manage to completely reconstruct what went wrong back then.

Cura should fix all of this auto-magically. It should either refuse to print one at a time or give a working solution. If the head does hit a print, let us know, because that's a bug.

Thanks! - How can I send you the "Cura"-File that had the problem? To make things worse: Once it worked, twice it didn't using that file...

and maybe check you gantry height in cura v.s. you physical gantry height, you would not be the first with an knocked-over item around 50mm high... cura has had different default heights over the years as the physical height in the UM2 also changed.

Sure. Do note that I hardly did any work on the old Cura. I have been involved with the new Cura from the start. The open beta should be released today.

Thanks for all replies so far! :-)

I haven't found out how to tell Cura in which order it shall print the parts. Or does Cura decide by itself? If yes, what's the logic? Or is ist the order in which the parts are put into Cura?

It decides by itself. The logic is rather complicated (has to do with the size of the fans and that object A can block B but B won't always block A)

I doubt there's a bug. I've played with this feature quite a bit. But if you find a bug it will be tough to reproduce at UM headquarters. They will probably want you to show that it's still broken on the newer version of Cura.
