Part 1 of 11 1:1 Stone Capital reproduction

Postby Alrawly » Wed Jan 31, 2018 8:15 pm

Over the past week I've been printing part one of eleven of a Stone Capital which we are reproducing to help stone masons carve an accurate replica.

Generally happy with how this turned out although there's a visible line where the printer was shutdown over night. When it restarted the first layer of filament seemed incomplete. Any tips on how to avoid this in future? Using PLA at 205 degrees with quite a high speed so may dial this back a touch.

First, would recommend you to update the motion board firmware from 1.1.1 to 1.1.6 which has a motor-lock function after pause. It will lock all the motors to avoid mis-operation during pause.
Second, since load and unload page is active during pause. Before resume the print, load some filament from that page. If the extrusion looks continous, then resume the print to ensure proper extrusion from the beginning of the printing.

While I agree with the advice to ensure you run the latest firmware, let's get to the actual problem.
You treated power loss recovery like it's something you can do all the time and have a perfect print. That's not what it's there for.
3D printing is a very technical process and has environmental factors at play. When you just flat out stop in the middle of a job, turn the machine off overnight everything cools and shrinks. Yes, PLA is low shrink/low warp, but it's not no shrink no warp. So assuming you can just come back the next day on some large object where the previous layers sat overnight and not have potential for a blemish or even worse failure.

Again, bottom line is that power loss recovery is a nice feature, but it's incapable of solving all the details of an overnight stop a job resume a job.

Thanks for the reply. That makes a lot of sense and can explain the more noticeable gap higher up on the model. While I agree completely that it would be preferable to leave the print running unfortunately with our current setup I'm unable to run over night for safety reasons. It may seem crazy but we have a lot of incredibly expensive equipment in the lab and are very limited for space so for the time being im a bit stuck. Understanding the limitations of the processes and materials will help with designs and may in future allow us to print for longer, for this job these imperfections are acceptable.
