delta undersized X and Y

[ember river]

So hi, my parts come out smaller (delta) how do i compensate. Z is fine X and Y is smaller by almost the same amount. Experimented with some M579 but as documentation says, that is not really and option due to cross talk on deltas.

GG @ember river, you just advanced to level 7!

[maiden oracle]

Are you sure your rod lengths are correct?

[ember river]

Well unless they were wrong in the firmware from the factory.

[maiden oracle]

Possibly

[ember river]

Ill check that

Probably a calibration issue with the arm length, yeah. Changing this will require recal on the delta radius, too (to get it printing flat).

[ember river]

Right, fun stuff.

FWIW I have had no issues using M579 to iron out the last couple tenths of a percent of off-scale after manually dialing in my delta's cal to print flat and at ~99.85% of sliced scale.

I do manual cal cycles to get as close as possible, then print 150mm bars and adjust them to 150.00mm with M579.

[ember river]

Yeah, got this machine "plug and play" well its not. From what i noticed im off by around 2.6 mm after hand messurment of arm and delta radius, got it down to 1.2mm

Might use the stuff to build a custom printer sooner or later anyways
