Smart Effector Tilt
-
@3mm The smart effector was designed with magballs in mind which is why I asked my question. They have a superior backlash performance since there is no slop in the fish-eye to ball....I know I know the terminology is wrong, but you should still be able to understand what I am saying.

See https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer#Section_Make_sure_your_build_is_accurate for common causes of effector tilt.

@3mm The brackets are 3d printed resin, but have some flaws. The lift is basically just where i had to force the bracket off the build plate.
Secondly, the bubble moves to the nearest edge, the effector tilt is not in only one axis. I'm taking that to mean it's a more general error than just one bracket.
As for the magnetic option mentioned later, removing the brackets and using the provided carriage adapters allow the effector to be used with magnetic arms (as designed i believe)@Danal the brackets are shaped to allow full movement, I'd run into that problem on bracket v1...
@BPisLife because the ones i saw advertised alongside the effector were quite expensive for a job hunting grad
@dc42 I'm wondering if the point made in carriage bearings being the same height is my problem. If the width between the carriage connections and effector connections are different the effector might twist? Thanks for the link, lots of good points for me to test

For sure, Huntleys Mag arms are expensive...but why dont build some yourself? some 6-8mm carbon rod..I used steel balls at the rods and magnets at the carrier and smart effector..constructing some 45° magnet holders is don e in some minutes. Costs me about 15-20€ and some time. ( I used nylon coated 12mm countersunk magnets)

Sounds like either you don't have the same bearing spacing at top and bottom of the rods, or the joints don't allow enough movement.

Hi, I'm sorry you think that I was chastising you, trust me I wasn't. However, the reason I gave the explanation I gave, was, and is in my opinion, that the Smart-Effector was in fact designed for mag-ball integration, and that the reason that they were not used is because of the points I cited. Was I mistaken? Without a custom adapter plate at the top, won't the mag-ball centers be wider than at the bottom? From what I've read on the 'Net, that's a big no-no and I presumed that's the obvious reason mag-ball arms were not employed (aside from the added cost), even though the Smart-Effector was designed to use them. I was not trying to be rude, and I apologize. I am sorry.

ps.. 'Fish-eyes' vernacular is ok with me, I just thought maybe I could dispel a bit of the confusion I hear on the 'Net re; their authentic moniker.There are 10 types of people: Those who understand binary and those who don't.

@barracuda72 basically because I hadn't thought that far
all just ebay stuff?@dc42 is bearing spacing essentially space between the ends of the two rods? So across carriage and across effector? Think the rods move ok, they certainly do effector end.
-
@3mm the smart effector comes with the adapters so the arms are perfectly spaced....either that or I bought the adapters along side it. Either way it makes the spacing perfect
-
@bpislife adapter is part of the package. Going to try printing brackets for them to see if it works, otherwise going with https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F132544828361

YES!!! Whatever the mechanism, heim-joint, mag ball, whatever, the "joint center" of the rods must be EXACTLY the same horizontal spacing at the effector and at the carriages. If not, several bad things happen, including effector tilt.
You should really use the circuit board spacers that came with the effector circuit board... but for those very hard-headed of us who don't, here is one choice for a carriage:

Note these are for HWIN style linear slides, and 9mm belts... but they are also openSCAD so can be adapted...

@danal I assumed that was the issue, I'll see if some brackets similar to my effector ones since the issue, otherwise I'll be looking for affordable (read budget
) magnet rods -
I used the Balls from Tinker Bills Link..because my Delta was a anycubic pulley in his first life so 200mm was enough. later i bought rods to make 310mm rods. Amazon and ebay makes it so easy
