Configuring RepRapFirmware SCARAPrinter
-
Hello,
Can anyone explain me this step?
Iif i have Proximal and Distal length 200mm, what will be my XYoffset?
If you specify xxx and yyy as zero in the M669 command or you leave out the X and Y parameters, then X0 Y0 will be the position of the axis of the proximal joint (which is an unreachable position in most SCARA architectures). You should specify xxx and yyy in the M669 command as the location you want for X0, Y0 relative to the proximal joint. In a typical case, the X offset will be positive by an amount somewhat smaller than the square printable X range, and the Y offset will be negative by about half the square printable Y range.
-
It depends on where you want X0 Y0 to be.
-
After homing i would X0 Y0 at centre of bed (see picture)
-
That depends on your axis definitions (M208).

; Axis Limits
M208 X-150 Y-110 Z0 S1 ; set axis minima
M208 X150 Y110 Z120 S0 ; set axis maxima -

In that case, X is 0 (no X offset), and Y is 110 + the offset between the proximal axis and the Ymin edge of the bed.

Offset between Proximal axis and Ymin edge is 130
so i could set in this way?
M669 K4 P200 D200 Annn: mmm Bnnn: mmm C0: 0: 0 Y240 ? -
And what about A B angle?
Is it correct in this way?
A -60:240 B -145:145

A -60:240 B -145:145
That looks about right from your diagram.

Thank you very much @dc42

@dc42 i could set in this way? without X value??
