Calibration (maybe a noob question)

Technical Details
1

I watched the video on calibration (vertical), and it seems, for the most part, straightforward; however, I had a question:

Are there designated ‘top ‘ belt anchors (for vertical frame setup), or when calibrating the Maslow 4.1, does it know which ones are tight, therefore the top anchors are irrelevant?

when you are doing calibration (now called ‘find anchor locations’) you are
taking multiple measurements to try and deduce where the anchors are by
measuring the length of the belts in different locations.

when you are on a horizontal frame, the machine does not move unless you pull it
with a belt

with a vertical frame, gravity will move the machine and the top belts are
always going to be tight (with the one exception of a bottom belt pulling hard)

When the machine takes it’s measurement for a point, all four belts need to be
tight. The machine doesn’t know if a belt is tight or not (no tension
measurement), all it knows is that the motor pulling on that belt ramped up to
some current limit in an attempt to move.

since a machine in vertical mode is hanging from the top anchors, I don’t
understand what you mean about ‘top anchors are irrelevant’?

Just to be clear, the designations for the top anchors are TL & TR (Top Left & Top Right) and they are always on the side away from where the power connects into the control board. On a vertical setup, if it is not correctly orientated, the belts connected to the top anchor positions will unspool and usually cause a jam and belt damage.

Ok, that’s what I was looking for. - I was not sure if there were designated ‘top’ anchors, which appears to be the case

Yes! The dust collection port should be on the bottom (like gravity down direction) along with the power cord for the router.
