Ok, im an idiot..... after reading the Smart effector install guide for the 5th time. it occurred to me in a photo that i had the rods installed wrong. i had connected the rods to each point in the triangle. i.e. right next to each other instead of spaced equally each rod next to its neighbor rod. like in this picture....

right, it travels smooth now. all directions travel as expected. thanks for all your help and suggestions. as always this is an excellent forum and the duet is a great piece of hardware!

but dont you fret ill be back with some other insane problem that i overlooked in the guide.....

@AndreS welp, as it zeros a little smoother i still cant move in any real direction with out the effector twisting and popping the rods off the towers.

@AndreS ok that might be why when moving it has a tendency to twist off and pop the rods off, i suspected as much. ill give that a shot and see what happens.

@Phaedrux ive got reprap firmware setup. ive got close on the measurements, i think...ill be the first to admit that i am complety noob at deltas. ive built one cartesian and one corexy. this is a whole new area for me. X(a), Y(b) and Z(c) all have to be in sequence correct? So and im asking you @Jackal too. If looking at the Front of the printer, with a tower on the front left and a tower on the front right and one center in the back.
Can it be x,y,z counterclockwise, or clockwise or what have you? @Jackal you say top tower? what does that mean?

@andre i was referring to using the move commands in DWC after installing the firmware and fixing the endstop positions. ive copied and pasted my config.g. i have not wired the smart effector yet so i havnt got to use the homing features yet. i wanted to make sure the motors are in the correct order before i go forward. also im waiting on the correct crimping tool.

The printer base im using is a geetech 301. im only using one extruder at this time. and ive replaced the effector and arms with the smart effector and haydens mag ball arms. they are the same length as the old arms. 215.83.

Hello!

Recently i bought a geetech 301 with a bad control board. after my wonderful experiences with the duet on my Tronxy X5S i decided to get another one.

turns out i dont know squat about how to wire or program a delta. i have also purchased the smart effector and carbon rods and mag ball set.

My first question is how are the motors to be wired? what denotes X, Y, and Z?

ive got it to the point where i can zero it to the end stops. but moving the print head seems to be opposite the way its supposed to work. when moving x or Y, on carriage moves while the others stay stationary. that seems reverse from the way ive seen them move.

I have not wired the smart effector or hot end yet. i got tired of crimping terminals by hand using side cutters. while i got reallllly good at it, im losing dexterity in the fingers folding them little tabs over. i broke down and ordered the crimping tool.

so TL;DR where is a good write up on wiring and programming deltas that doesnt dive directly into the spatial physics of the universe. id like to learn that eventually but most write ups seem to require a Stephan hawking level of education. and i consider myself to be just a normal dood teaching myself and my kid 3d printers in hopes to get a job in additive manufacturing someday.

Thanks
Ben
