Defining new Center Point (Not Home)

chainoversprocket = Top
chainoversprocketcomputed = 1
means your chain passes over the sprocket before going to the sled.

distperrotrightchaintolerance = 63.50000
distperrotleftchaintolerance = 63.50000
means you have not tuned the chain tolerances yet.

motoroffsety = 482.6
is the 2D vertical distance of the workspace top edge to the sprockets.

comport = /dev/tty.usbmodem1411
this is not a windows machine,

zaxis = 1
your Z axis is motorised

motorspacingx = 3008.91
means the distance between sprockets center is that

rotationradius = 140.0
if you use the rotation ring kit, the exact value is 138.14 mm

chainsagcorrection = 0
There is no sag correction for your lower corners. It will likely be too narrow at the bottom.

chainlength = 3360
You got 12 feet chains right?

zencodersteps = 17280
This is not the standard Z motor encoder setup.

Here are your choices for the home position:
(set when clicking on “define home” among the GroundControl upper right screen buttons)
homex = -30.0
homey = 273.29

kinematicstype = Triangular
the ring kit is what you use…

leftchaintolerance = 0
rightchaintolerance = 0
means you did not yet adjust chain pitch to improve precision ( this will eventually be assisted with the Holey Calibration)


1.2m = 4feet. that is the height of the workspace. then the top edge of the workspace is sais to be at 482.6mm.
Is that not right?

Have you chosen to place the home position at (-30,273.29) so it would look centered?
