Box
You need a box or some kind of frame to build everything into, the basic requirement is that the mounting steady enough to cope with the dispenser and its relative weight moving quite fast. Make sure it can’t move from its place when the machine is turned on.
To help you get started Baza (mucho kudos and props here) made some kickass plans you build your own Gimbal/box. You will be able to find the plans in the download section.
I would recommend using Perspex glass or something similar. It’s cheap, can be easily cut and glued and comes in various thickness’. But if you are going all out you could get it waterjetted in aluminium.
As for the esthetics of the box I suggest a few my-little-pony stickers, for confusion.
So now you have all your parts, jammed them into a box which looks ridiculous because you were too impatient to do it properly. Well ok, maybe you actually did make a reasonable piece of kit. Now we have to do the basic calibration.
Anyway whatever you turned up with now you need to get it to work. Don’t worry its not difficult and if you constructed your project properly it shouldn’t take long.
Did you install the pololu drivers?
Did you attach the usb cable to the pololu module and the computer, now check if the pololu module started up properly – just read the manual
Turn on the power switch to the pololu module in order to power the servos. The servos now twitch to life and set to their mid position. If you did good in the construction the dispenser will be aimed pretty close to the middle. If its not adjust it.
ztart ze zoftware (german scientist accent).
The software should immediately recognize the pololu module, if it doesn’t select it from the dropdown box or press update ports, if it doesn’t show than check connections otherwise still no connection, then look for a problem or you broke the shit.
Adjust the baud rate to the pololu module, mine still works fine at 19k but not at higher ones, think it has to do with the fact that I only have usb 1 in my laptop.
Check again and your done with this part, and your servos are centered.
Close the software.
