Starting a print half way up

I had a print fail after circa 25 hrs of circa 38. That file was lost when I turned the P2S off instead of cutting the jammed filament. Now I know better…..

Is it possible start the same print anew, but at a height I can fairly easily determine. I thought I read about slicing and starting from different heights, but I can’t seem to find anything now on how to do it.

I’m using studio for this.

Yeah you just move your model below the buildplate at the layer you want.

Ermm, I’m new at this…

Put the part printed model below the build plate or try to move the to be printed model partly below the build plate? How is that done … meanwhile I’m going to try to move the slice model (somehow).. nothing to lose if I don’t initiate print :upside_down_face:

To be clear, take the thing off your plate and clean it, it’s not going to resume “at that height”

You can measure the print, and cut the bottom off in the slicer, and now print just the top that is missing, and glue it together at the end.

If that’s ok for quality to you, or is possible given your model, then cut using the cut tool

Or use the move tool to force a cut [default feature of slicer - under the plate = not printed]

Yeah, that first bit was an attempt at fun.:laughing:

I have found the slider at the side and can see how to select the section I want - so now I will use your guidance to cut the model. My G. daughter will appreciate her mushroom, even if it has a joint - thanks

Yes, it’s possible.

If you can determine precisely where it failed, you can edit your gcode to include the warmup process, no leveling, and resume on the very next layer. It’s not a guarantee, but worst case you can print the second half and bond them together.

That’s a great last resort idea.
It’s a shame that studio doesn’t automatically save stopped print files it may keep paused (but that was not an option for me), but at least I now understand better how to pause and release a jammed filament.

I see others have posted about stalled filament drives (A1) they can be caused by many different things, but fixing the stall has led too many to turn the power off and lose the print file and or its position as in my case.

For clarity, there is no current method to resume a failed print.

As stated, you can “slice” a portion of the model, but there is not Bambu Studio process to start that portion at the point of failure, the starting layer.

You have to force that through manual processes by adding GCODE to the created file, this file cannot now go through cloud unless you edit the start GCODE for all subsequent prints, you would need to save the existing GCODE.

I agree it is annoying. However, unless you know exactly what you are doing, you could easily damage your printer.

This is as much for you as it is for others who read this later.

Messing with GCODE is beyond my current abilities. I think it’s important to always consider replies for the OP and others that may them, that is after all one of the reasons for the forum.

You asked if it was possible, I answered truthfully and accurately. Other users who read my response can do the exact same assessment of their abilities that you did.

There have been some similar posts about interrupted prints and one thing that’s unavoidable, even if you can restart the print at the exact point it stopped, is thermal shrinking as the model cools down. It will shrink in all dimensions just a little but that is generally enough to leave a visible seam line and can cause other issues. Printing to a cooled model may also cause interlayer adhesion issues between the new layer and cooled/old layer.

Malc’s point about printer damage is a good one too. Get the height wrong and you can bend an extruder nozzle or cause other damage if the nozzle hits the model.

I just wanted to thank all for the suggestions, I was able to visually identify the exact cut point and print just the remaining section.:grinning_face:
