NextCloud File Lock Error in Joplin

I encountered a problem recently on the Joplin desktop app where it couldn’t synchronize due to a file lock being stuck in NextCloud. It uses a file in the jopline data directories to determine sync status and lock status on files being edited, and this file was stuck locked in NextCloud with no way to delete it. I performed some searching, finding some blog posts on the subject and found this on how to solve it. I’ll be going through the manual solution to this problem and updating the process with my experience.

Ortur Laser Master 2 Air Assist

While the Ortur Laser Master 2 that I picked up is advertised as a laser engraver and not a laser cutter, it can do lightweight cutting and I was intent and optimizing that capability. After performing some research, I found that air assist would be a great modification to aid in this endeavor.

The air assist system was built with 1 main goal in mind, to make cutting with the laser more efficient. This will also reduce sooting and scorching by putting out fires while cutting.

Ortur Laser Master 2 Enclosure

The Ortur laser is completely open air, providing no assistance or infrastructure to vent the fumes away. I decided to work on an enclosure for these reasons. The enclosure has 2 main goals, to contain excess laser light from the room and to contain fumes from the laser so they can be exhausted. The exhaust could be a fan in the back of the box or using a vacuum table underneath the laser. In my case, I’ll be building a vacuum table to hold materials and exhaust fumes.

WLED with Home Assistant

Integrating WLED into Home Assistant is a relatively simple task.

Go to the integrations page on home assistant
Add a new integration and search for WLED
Add the ip

After the, you’re good to go. Home Assistant will show the unit as a number of entities, a light and a number of switches.

Ortur Laser Master 2 Software – LightBurn

One thing needed with every CNC driven machine is good software to control it and generate the gcode. There are two main options for the Ortur Laser Master 2. These are LaserGRBL and LightBurn. The Ortur uses LaserGRBL as the main control software out of the box while LightBurn is a commercial offering that costs $40. This article will be going through the LightBurn setup while I went through LaserGRBL in the past.

Focusing the Diode Laser on an Ortur Laser Master 2

Focusing the laser is just as important if not more important than leveling the bed of a 3d printer. A well focused laser will have tighter cuts, will engrave and cut faster and will have higher quality engravings. Getting the laser to a good focus point however can be difficult, and there are a few tricks to getting things to work smoothly.

Laser Safety Glasses

I recently picked up an Ortur Laser Master 2 engraver and cutter. With the new hardware to join my 3d printer in making things, comes new safety gear to use things with minimal risk (and prevent myself from going blind). I ended up going on an adventure to get the right safety equipment. My wife and I both wanted to work with the laser, so we both needed safety glasses.

WLED with ESP8266

I found a guide for running WLED on an ESP8266 micro controller to drive individually addressable RGB cables. I thought this would be a fun little project after working with the smart plugs and home assistant automations. Since WLED is another FOSS and cloud-free project, this still fits with my whole fully self hosted smart home ideal. Since no project is fool proof and I have run into small problems when working on the project.

Adding a Current Month Numeric Sensor to Home Assistant

I have a number of Christmas light strands in various windows around my house. These get turned on once a year when we remember they exist and its around Christmas time. I decided that these would be a good use for home assistant to add some Christmas lighting during November and December.

To do this, I wanted an automation that would turn on the lights during specific months, and not during others. Thus I needed the current month available as a condition for my automation. I quickly found out that Home Assistant does not have this type of data built in, but can have it added relatively easily. I didn’t know how most of this was supposed to go together, so after a little bit of guess and check, here is what I ended up with.
