Continuing prints after a black out
Posted: Wed Feb 08, 2017 2:57 am
Good night everyone!
I basically print from an SD card and w/o connection to the computer...And I don't have the LCD screen so far... therefore, I lose control of my prints after I lunch.
The reason I disconnect my computer is because 2-3 times it causes the print to stop (don't know the reason, just blocked)...so I never connected it again or printed directly from the computer.
But, if by any chance my printer stops (black out/my dog pulls the cord/any other), I have no way to continue the print from the point it stopped. Is it?
At this moment, what I'm doing to resolve this issue is:
- I take out the part/s from the building plate
- I measure the height of the last layer (let's say 15mm)
- I prepare a new print with the models sliced up to the part they were printed (all the rest above the 15mm)
- I print the 2nd half part/s
- I glue the parts together
This situation normally carries some mistakes and failures derived from the innacurate processes of manually measuring and gluing:
Some lines appears on the outside of the part or in the worst cases, the parts glue unaligned. To correct those mistakes a new manual process is needed: sanding.
Many times I get great parts (even better that the normal ones, because of the sanding) but with a lot of job. Some other times, I end up trashing both first and second printed parts...
As you can see, after a failure like that, a lot of manual processes are needed in order to don't lose many hours of print (of course I don't do any of that if the print is a simple/fast one).
Now my questions:
- Is it possible to continue a print launched from an SD after it accidentally stops?
- Is it possible to zero the Z axis with the parts still on the table? When I tried that, of course the parts ends up crushing the upper bridge of the machine...
- Maybe the Z axis can be "cheated" to be 0 at certain height (again let's say 15mm), but how can it be done?
- How do you avoid all these situations?
I listen to any suggestion in order to stop having these problems!
Many Many thanks!
