After finally getting my Cetus3D MkII 3D-printer I was eager to start to print. When I started through the steps to calibrate the printer by adjusting the build plate height, but the print head/nozzle refused to get close enough to the build plate to finish the calibration! The cables on the motor came in contact with the chassis of the printer! So the injector was 5mm from the build plate and couldn’t get any closer by increasing the step values. But there is an easy fix for the problem.
Can’t Remove Purgeable Disk Space
When trying to install Bootcamp on my MacBook Pro, I had to delete a lot of files to get enough space to be able to accommodate for a Bootcamp partition on the drive. But even after removing around 60 GB of storage, Mac OS Sierra could still not make a large enough partition for Windows. When checking with Disk Utility it showed that indeed I had enough space, but there was a part called Purgeable that was impossible to move. No tools from Apple are available to handle this, but here’s how I fixed it.
Mac OS X Yosemite was released 16th of October. Naturally I installed it on all my machines. My new work computer, a MacBook Air 13″ worked perfectly before the upgrade, but after the installation I’ve had constant problem with Wi-Fi. No problems what so ever before upgrading, so obviously something is screwed up with Yosemite. My private machine, a mid-2014 MacBook Pro Retina has no problems at all.
When searching through Apples support forum, there’s a lot of similar stories (and also a lot of noise.) it’s incredible that Apple still haven’t fixed the problem, with the network connection going down every five minutes. The only fix is to turn of wifi and turn it back on again. Incredible…
There’s an article over at medium with a possible temporary fix that I will try when I get back to work.
SqueezePlug problem where Squeezelite refuse to start
I installed a Raspberry Pi in my livingroom as a Squeezebox music Server/Player, using a SqueezePlug image. But when I tried to install the Squeezelite player, it refused to start. I tried to uninstall and reinstall, selecting another USB Audio Interface, but the problem persisted. After checking around and doing a some experimenting, I found that I could start Squeezelite manually from the terminal prompt, but if I tried to start it with the init.d or service script, it refused to start. So I started to dig around and experimented with changing the settings for Squeezelite and I found the problem…
Apple Airport Utility how to display more information
While doing a Wi-Fi scan at work to get better reception and optimize the location and channel selection using NetSpot Wi-Fi Reporter, I had a problem. Our wireless network is set up with roaming, so when NetSpot Manager displays the scanned Wi-Fi device, it only shows the MAC address. So identifying an AirPort Extreme wireless router can be difficult, especially since Apple has simplified the user interface of AirPort Utility and removed a lot of information. One of them being what MAC address the AirPort unit has. So I needed a solution.
