marlin armleven setup not clear

Hello all,

Im in the process of reutilising a mechanical arm used to place things ins a automated chemical machine. it has a arm with two steppers, wormwheel drive and a chain though the first arm to the second. very sleek. i will post pictures soon. it works like the reprap morgan or a scara arm.

but now the question.

I downloaded the marlin armlevel firmware from [github.com] and I want to fill in the proper information for my setup but I have no idea what is ment:

// Center-to-center distance of the holes in the diagonal push rods.
//#define DELTA_DIAGONAL_ROD 250.0 // mm

// Horizontal offset from middle of printer to smooth rod center.
//#define DELTA_SMOOTH_ROD_OFFSET 175.0 // mm

// Horizontal offset of the universal joints on the end effector.
//#define DELTA_EFFECTOR_OFFSET 33.0 // mm

// Horizontal offset of the universal joints on the carriages.
//#define DELTA_CARRIAGE_OFFSET 18.0 // mm

can anyone explain them?

(edit) i now understand that those values are for a true deltabot. mine is more like the morgan, although the secundary arm is operated trough a chain via the primary arm.

See if any of these links answer your questions:

Looking forward to seeing some pictures!

those ones look like delta values because for new drive systems is recomended to reuse it because of ram memory, look at comments to know what are they

I have modified Repetier firmware for my drive system, I havent tested yet but looks fine
Maybe I could help you if you want to adapt it
