m new to the Arduino world and looking for advice for a project which I hope to solve by the use of the Arduino world.
To introduce myself:
Im a technician working in the industrial automation industry, managing customer support for one of the big solution provider. I have some knowledge in programming and general technical skills with electronics and mechanics. I have a fairly good equipped workshop.
I want to build a XYZ pic
n place machine for a whole room 3,5 x 3,5 x 3m. I know, that there are several profession solutions around, but thats out of range of my hobby budget, so I want to build this from scratch. Something like a very big 3D printer or milling machine.
Because I need to use 7 stepper motors to drive this monstrum I plan to use several small arduino boards to control this. Each motor will be controlled by it`s own arduino board and a dedicated stepper motor driver and will have a seperate power supply.
Because missed steps are a big problem in my setup (X axis will be driven by 4 motors), I need to use optical encoder on every motor which must be read by an interrupt routine.
The 7 arduino/motor boards should be controlled by a master device (possibly also an Arduino).
I`m looking for a communication solution to connect these 8 systems together which does not affect the generation of the stepping pulses and the encoder readout. The communication must be "by wire", I cannot use any wireless solution for this project!
I did several searches on this forum during the last days, but I did not find something which will match.
It would be nice if someone has some ideas to manage this.
