Lead screw cleaning guide CR-10 and other TR8x8

Manually written Gcode cleaning files for the cr-10
Required:
Old credit card or similar
Tissues
Isopropanol or other high conc alcohol
replacement lubricant (teflon based only) (I used muc off dry lube)
Test the 380mm gcode script (or modify it for however long your Z axis actually is. You can find out your total by moving z on your printers control box, Note if you have changed extruder, hotend or bed this will be different for stock. Mine was 400 now its 380.
If needed edit one of the gcode scripts to say change 330 to 100 for a Z=100max printer.
Run the script on the printer, be prepared to kill it if anything goes wrong. It will cycle up, home and repeat.
Get a tissue, dab a single strip along it with alcohol generously, then wrap the alcohol wet tissue around one long edge of the card and hold it into your leadscrew. It should move up.
After getting use to it, push snugly on the screw to make sure the card is fully engaged with the slot. If too much gunk builds up, slide the card along so the gunk now goes on a clean part of the tissue.
Unwrap the card, move the tissue so a clean part is over the edge, rewrap it and repeat both above and below your moving gantry until your screws are reasonably clean.
They will never be fully silver, dont waste your time trying, its going to be messy in weeks again.
when done wrap a finger around your leadscrew (whilst the gcode is still running) and drip lube onto the inner joint (wrinkle) of your finger, it should run down your finger and into the screw. Do this in medium amounts and if any looks like its going to drip into a motor grab a tissue and stop it.
