My k40 have absolutely no form of dial indicator so I made this knob and dial gauge to make repeat cuts easier.
I used a red oil marker to color in the line, but nail polish or whatever you have on hand is probably fine too.
This is designed to fit a FULLY seated potentiometer (see the image) meaning the bottom is recessed a fair amount to account for more of the threaded shaft. If yours has the little tabs keeping it off the back of the control plate the knob would probably still work but the pot shaft won't go in nearly as far so it won't be as strong of a connection.
(Regardless its best to drill corresponding holes for the tabs and bend the tab over the top of the control plate to keep the pot from ever spinning on you and putting a strain on your cables.)
This is a slip fit on my machine so a small dab of lock tight (blue) or a very small dab super glue or hot glue may be needed to keep it in place depending on your printer quality.
NOTE: To remove the old stock k40 knob DO NOT just pry it off. You have to pry off just the top of the knob and remove the nut or you risk damaging your potentiometer
