Octoprint Printer Profile

[NavyDT]

Hello all,

So ive got the M2 up and running. Ive printed the bracelet that came with the machine and also printed the Raspberry PI 3 enclosure from thingiverse http://www.thingiverse.com/thing:922740

So here is my question.

When i put a model into Simplify 3d and slice it up it says it will take 1 hour i import it over to the octoprint and pull it up, it says it will take one hour.

After the print starts, the time required shoots up to 15 hours... Is this normal?

Are the printer profiles in the octopi.local only used for the cura slicer that is build into octoprint or is that some how over riding what simplify 3d is doing?

Im sorry if this sounds stupid but i really appreciate everything that you guys have helped me with.

Below is an example of a print where the print time in simplify 3d and octoprint are way off from eachother


Very Respectfully,

Few things going on here. Let me try to summarize.

1) Print times in S3D are known to be highly inaccurate. You can normally double the time it says, that is more accurate. There are threads on here that you can search for about that.

2) Octoprint - Similar story, the time can and will change. It's essentially a guess as well.

I've been out of the 3D printing game for about 2 years (getting an M2 very soon), but when I worked with a Makerbot I noticed similar time differences as you show. I don't know if or how the time estimate changed, but I found that the print time used to be based on time_per_layer * number_of_layers. I'm interested to see if anyone can chime in on any advances towards this issue.

There is essentially too much going on to be accurate. The speed is one thing, the number of retractions, print head moves, the list goes on and on.

I am not expert, but I print a lot, and this is really the deal.

However, I can say octoprint is getting better, where it does have memory of the last time you printed the object and how long it took.

Just a side note: Don't forget to make sure your date/time is correct on the Pi. Unless you have an RTC module, it will likely be way, way, way off every time you power it on. And in most cases, the NTP service won't correct it if it's off by too much.

This will cause ridiculous time estimates.

SSH into the Pi and check with the "date" command. To set it from the console, use something like this:

Code: Select all

sudo date --date='2016-12-26 13:29:00'
