Hello everyone!
I want to show everyone my development
It is a precision motion controller, X, Y
Indicates the starting point and ending point of the route, then you can program the acceleration and deceleration, showing the travel time, you can vary the overall speed of the trajectory, is very accurate, both in time and position.
has two propeller, one handles the controls and relays, the second handles the display, mathematical calculations and the engines, propellers are connected by series.
360º=240.000 micro steps

Thanks for the help to control the LCD Erik


A greeting and to enjoy it!

    Cool. I like the way you can tweak the accel/decel ramp.

    On youtube, there is no clarity
    It is better to see on Vimeo.
    The movement is best on youtube.

    Thanks ElectricAye & Cluso99!

    A very smart piece of work!

    Will you be posting any of the code elements?

    Regards,

    It's a prototype, I can display the code of the LCD
    Now I vacaiones, around, the graphics library public.
    The rest is part of the final draft, I think my client would not be happy if I show the code. ;-)

    Thanks TonY

    Very nice! Thanks for posting to youtube too. For some reason I couldn't see it on vimeo yesterday, but today I can.

    You're using stepper motors? With some sort of gear reduction?

    Very cool project. I wish we could learn more but I understand your client may not like that.

    Hi Everyone!

    If you want to play with some motion control code, Attached is my 5 axis linear interpolative drive code for a machine I developed. (steppers)

    I do have speed control, but I don't have speed ramping in this code , however, once you understand the basic concept it shouldn't be difficult to add.

    I got enough speed out of spin for this to work in my application, it would be great if someone wants to recode it in assembly. I managed to stuff 4 axis with ramping into the SX-52
    a few years ago, so I would think it might fit into a propeller cog or two easily.

    Stepper motors are 1.2 º
    The routine generate ramps and motor movements are in assembly language.
    The LCD driver is based on a program of Erik, in this version, the drawing command were SPIN.
    Now is all assembly, draw circles, lines, dots, squares. has less font sizes, but has a way of minifuente, very useful to show tables.

    When you are at home, I see your code
    Thanks!

    Hi

    Es un trabajo muy bueno, y se nota que tiene muchisimas horas de desarrollo, supongo que la parte mecanica tambien es tuya.
    Sabiendo lo poco que se del emsamblador de Propeller me parece un trabajo faraonico

    Traduccion de ´Google:

    It is a very good work, and it shows that you have many hours of development, I guess the mechanism is also yours.
    I Know a bit of Propeller assembling languaje and it is a very hard work to do.
