Hello there
I am trying to build an pullstruder (an device that transforms plastic bottles into 3d printer filament) and i want to use parts from an old CL-260 (ultimaker 2 clone)
I managed to design and build the physical part of the project but now i am really struggling with the "firmware" part.
I want to write a simple code that powers on the part that used to heat the nozzle, to read the temperature and to turn a stepper motor.
I started with the stepper motor and made some kind of progress using an Arduino uno and breadboard but when i move the driver and the motor on the ramps things get out of hand and nothing works anymore.
I would be grateful for any advice
(also please explain why a driver would fry if you disconnected the motor and in what order should i disconnect things)
Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (More generally, rewiring anything while it is powered is asking for trouble.)
So right now i moved the components back to the Arduino Uno board and now everything spins, but i cant make it stop.
The connections that i used are the basic connections for a 3D printer using the Arduino mega and the Ramps 1.4, the drivers are pinned down to the Ramps and the ramps is connected to the arduino board.
I do not have the LCD display and i plugged the motor and driver in the E position and the powr supply is connected like in the photo (everything else was removed).
