Timelapse mod for the M2/3 with Octoprint?

Post by sprior » Mon Apr 09, 2018 8:37 pm

I was thinking that one thing the movable bed on the Y axis does not do well is allow for a timelapse of the print and had a thought.

I believe that OctoPrint captures one image per layer to create the timelapse. What if there was a sensor under the bed which triggered when the Y axis was maybe in the center and that sensor was connected to the Raspberry Pi - Octoprint would then be modified such that instead of capturing one image on layer change it would instead capture one image on layer change when the Y axis was centered. Sure this wouldn't work if you printed something small off to the front or back of the bed, but that seems rare.

I think the sensor itself would be pretty easy.

Any thoughts? Sound interesting?

Even easier: add a G0 Y.. command to the layer change code block in the slicer, sending the Y axis wherever you think appropriate.

Slic3r can add commands before and after doing the layer change, which means you'd put it in the "before" block; S3D or whatever you're using surely has a similar function. Octoprint then triggers the camera when the Z-axis changes and it should Just Work.

Now, if you have a problem with the nozzle whacking the just-printed layer, then you might not want to whisk the platform around. In which case I'd say time-lapse pix shouldn't be your highest priority problem ... [grin]

That would also work, but would slow down the print because of the vanity travels, and also wouldn't be good at all in vase mode. I guess I was thinking of something more opportunistic - the picture wouldn't necessarily be taken at the very beginning of each layer (but do you really care), it would be taken whenever the bed just happened to be in the right spot.

So sorry! I hadn’t logged on in a while.
Yes, that is the correct configuration.
