The math behind the inverse kinematics is based on trigonometry, and the result depends solely on the lengths of the two arms.įrom here can set the desired bed zero position, and get the values for the MANUAL_X_HOME_POS variables. Briefly, with inverse kinematics we calculate at what angles the two arms should position in order to reach a given X, Y coordinate. In my previous tutorial I already explained what is inverse kinematics and how it works with this SCARA robot so for more details you can check that tutorial out. This is based on an open-source design by Tyler Williams which implements inverse kinematics on the G-codes generated for normal cartesian systems.

The “MORGAN_SCARA” is for parallel SCARA robot and the “MP_SCARA” is for serial SCARA robot, just like the one we have.
# define SCARA_OFFSET_X 300 // (mm) # define SCARA_OFFSET_Y 150 // (mm) Code language: Arduino ( arduino )
# define SCARA_LINKAGE_1 228.15 // Arm 1 lenght - 228(mm) # define SCARA_LINKAGE_2 136.2 // Arm 2 lenght - 136.5(mm) // SCARA tower offset (position of Tower relative to bed zero position) // This needs to be reasonably accurate as it defines the printbed position in the SCARA space. */ # define MP_SCARA # if EITHER(MORGAN_SCARA, MP_SCARA) // If movement is choppy try lowering this value # define SCARA_SEGMENTS_PER_SECOND 100 // Length of inner and outer support arms. * Mostly Printed SCARA is an open source design by Tyler Williams. * Implemented and slightly reworked by JCERNY in June, 2014. * MORGAN_SCARA was developed by QHARLEY in South Africa in 2012-2013. The first thing here is to select the type of SCARA robot we have. So, once we re-open the Marlin folder with the “SCARA” configuration files, we can open the Configuration.h file and edit some parameters according to our machine.

Once I connected everything as explained, I squeezed a little bit the wires and covered electronics so that everything looks nice and clean.Īctually, before we open the Marlin folder, we should first go to the Configuration repository on from where we can download some pre-tested configuration files which are suitable for us.

The steppers motors go right above the drivers and the limit switches which are Normally Closed with two wires go at the endstops S and – pins for each axis respectively.įor controlling the laser module, we will use the pin D9 which in a 3D printer setup is used for controlling a fan.
