My 3D Touch arrived this week and I spent the morning installing and setting it up. I purchased a 3D Touch in a package for the Ender 3 however I only used the 3D Touch and the extension cable as I was plugging it into my skr 1.4.
The kit did come with a bracket but I printed this as it provided me with the x/y offsets for the mount.
The install was simple and I got some tips from this video on the install. I followed this video for configuration of the Marlin firmware.
Because I purchased the kit my 3D Touch had a cable crossed to work with the adapters provided so I had to uncross this connection but thats the only change I made.
After I calibrated the 3D Touch I ran a bit of software that produces a visual representation of your bed level. As you can see mine is not flat but not to bad at all. At some external points of my bed my level may have been out by one layer.
Here is a quick pic of my first layer on the next print I ran.
All in all I am very happy with the addition. After the Marlin firmware update I got extra buttons on my touch screen for configuration of the bed levelling. I am pleased I learned how to manually bed level before getting this as I can appreciate what this is doing much more and I feel manual bed levelling is a key skill to have with 3D printing.
One slight annoyance is you can not turn off the red led on the 3D Touch when the print is running.
There is part of my which wishes I had gone for the BLTouch as it is reported to be more accurate, but twice the cost. I don’t think this will effect me at the moment as my bed is pretty flat but in the long term I may update to the BLTouch.
