Timelaps not working consistantly

by santanig5

Anyone else having an issue with Timelaps?
I'm running OctoPrint 1.4.2 Python 2.7.13 OctoPi 0.15.1 currently, but noticed some time ago that my timelaps was not saving consistently, it seems to work on shorter prints, but the longer ones are just lost.
Any ideas?

Polar cloud plugin not installing

by SnekBoi

About a month ago I setup octoprint on my raspberry pi and have used it since and it’s been a game changer. The bad thing is I can’t monitor prints away from home. I figured the polar cloud plug-in would help but now it won’t install. I’ve tried using URL and the plugin repository. It gives me the done message after I’ve attempted to install and even after the restart it won’t show up in my plugin list. Any solutions?

Script to read enclosure temperature (Octopi DS18B20 mod)

by pelicanlabs

I use Octoprint with my Qidi X-Max. I have added a DS18B20 sensor for reading the temperature for inside the enclosure. This script produces a temperature value, for use with the Navbar Temperature plugin.

Place in /usr/local/bin

Change the serial number to match your sensor.

Controlling the power to a 3D printer via Octoprint - inrush

by rjelbert

Some people have commented on Octoprint relay contacts getting stuck ON when using a relay to switch the mains power to their 3D printer. This is because the relay contacts are being welded together by something called "inrush" current. Many switched mode power supplies demand a very high initial current spike when they are first switched on - this inrush current can be 50A or more for a very short time and it happens just as the large capacitors charge inside the PSU. I have created an active inrush eliminator to make it safe to control the printer PSU via Octoprint. See: https://www.thingiverse.com/thing:4413002
I hope this is helpful and solves some of the issues caused by low cost switched mode power supplies in our 3D printers.
