Skelestruder Usage / Tips

You can view the nozzle during the print which is great for troubleshooting and watching the first layer!

By turning PINDA adjust knob, it is simple to adjust PINDA height. For example when swapping between smooth and textured PEI sheet or different brand nozzles.

Turn knob counterclockwise (looking down at bed) to lower PINDA which increases nozzle clearance to bed.

Each detent click is 0.1mm height change. You can use this to easily bring down a high Live Z value. Example, 3 clicks clockwise subtracts 0.300 from Live Z.

My textured PEI sheet is about 0.2 thinner than the smooth. So when I swap, I simply adjust the PINDA and don't even change the Live Z or run first layer calibration. It just works.

Unhook tensioner by lifting knob up slightly while sliding out of idler. Then drop slightly to release spring tension and pull tensioner out completely.

Watch pinda cable when removing and installing tensioner

Now idler gate can be swung all the way up. This allows easy maintenance, clearing jams, or setting MMU load distances.

Advanced Use: between MMU loads, I sometimes open this up and clean out debris.

To adjust tension on idler, turn tensioner knob clockwise (looking down) to increase tension.

Turn 1/2 turns only and make sure pivots are set in idler detents. There are indicators on the top of the knob aligned with the pivots.

May need to hold screw head to keep it from turning.

To briefly disengage Bondtech gears for manual load / unload, just pull up from under idler edge (not the knob!) slightly until you can free filament.

You can brace your thumb on the filament cover.

Use this to catch/hold the filament while waiting for nozzle to heat before fully loading.

There is a sight line between the horizontal lever of idler and top edge of Ecage F.

When unloaded, the idler will be below this edge

When filament is successfully grabbed by gears, the idler will rise up above this edge. Useful for MMU2 debug.

To check if your Bondtech gears run aligned and see what effect they are having on your filament, unscrew the Cover/Cartridge during a print

Do not fully unscrew the front screw. It holds the Cover to the Cartridge and lets you pull out both together

Now you can watch the gears driving down the filament and adjust tension as needed

This is for advanced users and risk of damage if not careful. X-carriage will move on its own since still printing.
