Update V2.5 Made changes to the deploy bar assembly to tighten tolerances and give better coverage of the slideclip this is likely to be the last update for a while as I'm fairly happy with the current design I will update with a way to deal with the filament problem but that will likely be an existing solution elsewhere. I do hope to have a tutorial out soon to cover the full process.
Update V2.4 Tightened tolerances on the slideclip and changed the handle piece to work better with the deploy bar.
Update V2.3 Huge update.
Automatic deployment is now released! we have achieved full ABL on the cheap
Added a new stowage bar that requires not additional hardware
Made the slideclip easier to print and tightened up some tolerances in the slidelock

Update V2.2 minor adjustment to the stowage bar and gcode
Update V2.1: Automated probe stowage.
A few small tweaks and a stick is all it took to automate stowing the probe for printing. I plan for deployment as well but I need to take some time planning it out. Files updated to make the change are indicated in their name. Instructions for implementing this will follow in the setup section here is a video to demo how it works https://www.youtube.com/watch?v=D1w-PWs0ABs.
To keep in the spirit of the original model I have designed this remix to only require stock parts and an extension of the Z-probe wire so that it can be run in the loom. To make that happen I had to make some precise pressure fit pieces. As such before attempting this design you will need to have a decent calibration of your printer. For that I recommend the teaching tech calibration guide https://teachingtechyt.github.io/calibration.html#intro
At minimum you should have your E-steps and flow rate tuned in, However I also strongly recommend having Linear advance enabled if possible. As long as you don't have a creality silent mainboard you should be able to do so. Additionally I strongly recommend printing on a raft. This is to counteract elephants foot to improve accuracy further and reduce the post processing needed on the prints
This project is still evolving and I have some amazing additions coming so keep an eye out.
