3D Print
First, print the capstan_motor and capstan_pulley with a 3D printer.
I tried to use two 3D printers simultaneously to proceed efficiently, but one of the printers stopped printing midway.
The cause was that ABS used by the previous user had clogged the nozzle. It seems the preheat temperature setting was too low for ABS, as it was set for PLA. I learned that in an environment where multiple users use the same printer, it is necessary to be careful when preheating.
Laser Cut
Cut out two each of Y-Axis_Pulley and Y-Axis_Motor with a laser cutter.
Assembling
Now that all the parts are ready, we will begin the assembly process.
Routing and tensioning
Routing and tensioning the fishing line between the motors and pulleys.
Done.
Installing the Limit Switches
After ensuring that the wiring wires are long enough so as not to impede the movement of the X-Axis, we will wire the limit switches to the NO (normally open) and Common terminals.
For safety, we will also use heat-shrink tubing.
Operational Check
We will verify the operation of the assembled CoreXY module.
1.Connect each motor of the CoreXY to the Stepper Module.
2.Connect the Stepper Modules to the PC using USB cables.
3.Using the JavaScript created by the instructor,control the CoreXY module from modular-things.
