I have been looking for information on belt calibration and can only find belt replacement due to damage.
However, changing the belts without calibrating them I imagine is inviting disaster. There is nothing about an official calibration system for these printers. Just the issue of tightening the screw on the left.
Is there an official measurement using a tensiometer?
The only information I’ve been able to find so far is 110-120 Hz when strummed, using the Gates app in motorcycle/scooter mode. I’ve just done a tuning pass using this method today, and an re-printing the gridfinity case top that was failing consistently. We’re within an hour of where it always failed before, I’ll hang out here and let you know how it goes.
Like most K1C maintenance procedures, it really wasn’t all that bad. You absolutely will want a good screwdriver-type 2mm hex wrench, preferably both straight and ball-end. I have a ball-end and I ordered a straight one to add to the toolkit today (a decent Bondhuis one is $5 at the A-store).
I also printed a little 150mm long block with a pair of 8mm rod supports to make it easy to get the X-gap bang on 150mm. I can make the TinkerCad design public if anyone is interested, it’s much easier to move the print head out of way when fumbling with screws, then pop this it to bap the head back into place to strum.
