MPMD Bed Clips Upgrade Part 2: Calibration (poor video quality)

READ THE VIDEO DESCRIPTION FOR MORE INFORMATION!!!

This video demonstrates the calibration of the upgraded bed hold down clips for the Monoprice Mini Delta 3D Printer.

This is the same information that is covered in the existing tutorials, but some people need extra help, so I made the video. The quality of this video is pretty bad, but I guess if you need the extra help, you will put up with it.

See Part 1 for the explanation as to why this mod is important and for initial installation.


How well does this actually work? See my other videos for calibration steps and checkout the final results here (108 mm diameter print):

Copy-Pasted from Dennis's Tutorial for the anti-Facebook users. Heat the bed up first before doing this.

BED CLIP ALIGNMENT:

1) Screw the 4-40 in until the clip just touches the bed on all 3 clips.

2) Power on the printer so the bed switches activate the single button light. It helps if the head is homed.

3) Slip a 0.24mm shim (110# index card stock), between the bed and one clip. Adjust the 4-40 screw until it is right at the point of actuating the switch then back it off a hair so the switch is off, but actuates if a not much more than a feather touches the bed. You may have to go back and forth a couple of times to get it just right. When adjusting the 4-40 screw with the hex key, you should not have to hold onto the bed clip to keep it from rotating. If it does, then either you did not get the clip tightened enough, or your 4-40 thread hole is too tight.

Also put the short end of the hex key into the screw so that you have the long arm to give more leverage and control over the angle, since it only takes a couple of degrees motion to make the final adjustment.

4) Do the alignment step on the other two clips one at a time, then go back around the bed double checking that none of the adjustments moved. Readjust as needed.

You now have a precision aligned bed/switch combination that will make it much easier to get repeatable first layers on your prints with G29 auto leveling.
