ABL (Auto Bed Leveling) on the Creality CR-10

September 27th, 2021

In an effort to enhance my 3D Printing bed adhesion (with my fairly warped bed), I added an ABL to my Creality CR-10.  Initially, I went with a genuine BLTouch from Creality, but wasn't happy with the results so moved to a EZ-ABL from TH3D.  Here are a number of links related to the ABL setup.

Raspberry Pi 7 Inch Touchscreen Case

September 24th, 2021

This is a beautiful case for a Raspberry Pi 3 7 inch touchscreen (and Pi).  Unfortunately, the center section hasn't been updated for a Raspberry Pi 4, however, in my case, I had an existing RPI 3 (and 3.5" touchscreen) that I needed to upgrade to a larger screen to handle OctoScreen/OctoPrint.  There were some comments on Thingiverse that it was for the "older" 7" touchscreens while the newer ones were upside down and that does seem to be the case, however, it's easily handled by setting the rotation in config.txt.

Charging/Storage with the iMax B6 Mini

September 24th, 2021

I have a Li-Po battery that I use for spot welding battery packs.  I use the iMax B6 Mini balance charger to charge (and discharge) the battery.  Since I only use it once in a while, it can be a bit confusing to remember how to set it up properly.

IMPORTANT: Charging LiPo's comes with an inherent risk.  ALWAYS place the battery in a fireproof charging bag to be safe.

Connect the balance charger lead (small white connector) from the Turnigy battery to the Balance Socket on the iMax B6 Mini.  
Use the appropriate connector for the Output on the iMax and connect to the XT-90 (yellow) connector
Set the iMax B6 Mini to:

  • LiPo Balance Chg
  • 5.0 A
  • 11.1V(3S)

The 5.0 Amps should be the same as the amp hour rating of the battery - rounding DOWN if necessary.
The 11.1V(3S) is the number of cells in the battery (3 for the Turnigy)

 

The battery needs to be discharged to a certain level for long term storage.  To do so, set the iMax B6 up as follows:

  • LiPo Storage
  • 5.0 A
  • 11.1V(3S)

To start the charge/discharge operation, press and hold the ENTER/Start button.

The iMax B6 can be used to test and recondition 18650 Li-ion batteries.
