Benefits of Marlin 2.0.9 - https://all3dp.com/2/marlin-2-0-features/

Biggest Reason was: Improved thermal runaway system: This beloved feature in Marlin 1 is now even better. It’ll protect your printer from overheating and causing any harm to itself or surrounding objects.

This maintenance release includes a number of fixes and improvements from contributors, testers, and co-developers.

Just copy the file on a blank MicroSD card and turn on the printer, it needs to be unique from a previous one.

It WAS necessary to reset the EPROM; otherwise, the printer kept starting with an error.

Format Micro SD Card for Ender 3

Refer: https://www.3dprintbeast.com/how-to-format-ender-3-pro-sd-card/

Windows

  • Start by bringing the Disk Management window up. You can do this by right-clicking the Start Menu and clicking Disk Management in the menu that comes up.
  • Find the SD card in the lists of disks (you should be looking at the bottom pane as the top pane is the list of volumes and not disks). If the labels aren’t helpful, you can figure out which disk is the SD card by looking at the capacity of the disks.
  • Right-click the volume(s) that belong to the SD card (they are listed right next to the disk) and delete them. Be warned that this process will wipe all of the data on the card.
  • Upon successfully deleting all the volumes, you should see a pane that says “Unallocated” next to your SD card and no other volumes, which confirms that you successfully deleted all the volumes.
  • Now, right-click the SD card itself and select Properties.
  • Click the Volumes tab in the dialog, and look at the partition style line. If it shows Master Boot Record (MBR), move to step 11. You can close the dialog and go back to the Disk Management window after gathering this information.
  • Right-click the Start Menu, choose Windows PowerShell (Admin), and then type diskpart in the command line that came up.
  • When the prompt starts showing DISKPART>, input the command
  • select disk X
  • where X is the number of the disk. You can find this number by looking at the Disk Management window from earlier.
  • Upon successfully selecting the disk, you will see the output Disk X is now the selected disk. At this point, all you have to do is to input the command
  • convert MBR
  • Upon success, you should see the output DiskPart successfully converted the selected disk to MBR format.
  • To confirm that the process was successful, right-click the disk in Disk Management, go to Properties, and then go to the Volumes tab once again to check the partition style. If it’s showing Master Boot Record (MBR), all is good.
  • Bring the Disk Management window up, right-click the box that shows Unallocated, and choose New Simple Volume. Click Next until you reach the Format Partition dialog, and enable the Format this volume with the following settings radio button. Set file system to FAT32 and conclude the process by clicking Next and Finish, respectively.

Linking Domains to your GoDaddy Account

When GoDaddy upgraded and change my server package, we move my domains from one plan to another; however, the sites never went live on the new servers. This was because GoDaddy's automated process did not update my DNS settings properly. Do this manually.

Get the IP address of the new server, and you need to go through each domain that you own and update the A records for the DNS.

Delete a file starting with a dash/hypen on Linux on the command line

So you have a file that starts with a dash/hyphen/- and need to delete it. But when you try to do so, the "rm" command complains that you have passed an "invalid option –". This post looks at the simple solution to deleting a file that starts with a dash/hyphen.

As an example, doing a directory listing gives you something like this:

$ ls -l
total 678586
-rw-r--r-- 1 root root        54 Apr 29 15:39 -.log
-rw-r--r-- 1 root root     26819 Apr 30 13:17 210.5.53.35.log
-rw-r--r-- 1 root root     18114 Apr 30 01:37 210.5.53.36.log
-rw-r--r-- 1 root root     18410 Apr 30 01:37 210.5.53.37.log

You try to delete the -.log file like this:

rm -.log

and rm complains like this:

rm: invalid option -- .
Try rm ./-.log' to remove the file -.log'.
Try `rm --help' for more information.

The answer is actually supplied in the error message, which is fairly unusual for a Linux/Unix command. Instead of doing rm -.log you simply add ./ to the start and run this instead:

rm ./-.log

This will also work for other command line utilities you need to run against a file starting with a hypen/dash.
