Controlling the printer using arduino code

Hi there,

I have a project at university that uses a velleman k8200 printer but not as a printer as such.

I want to run a code to run 2 stepper motors with a const acceleration from a sketch in the arduino software. Does anyone have any tips on how to do that?

Thanks in advance!!

constant speed, or accelleration?
What for?

Cont acceleration.

Basically I’ve replace the y carriage, theres no heat bed etc, just a wooden ply board that has these 2 posts holding a stepper motor and bearing with an acrylic tube attached.
What I want to do is run an arduino code so that the tube accelerates with const acceleration, and then the y axis stepper also linearly accelerates (much slower) so that extruded plastic is wound round the acrylic tube faster and faster.
But I have no idea how to actually run an arduino sketch on the printer.

Thanks,
Matt

Thats a picture to help you visualise the acrylic tube setup.

Well, you can’t simply run an arduino sketch on it, as it would have to replace the firmware.
What you can do is generate a G-code file for sending it to the printer.

Or write a simple application, perhaps in proccessing (almostthe same as arduino ide)
and make it send g-code commands directly via usb serial connection to the printer.

Hi Christian,

Thanks for the info, any helpful tips or links to show me how to generate a gcode file to do this?

Thanks,

For a start you can have a look at the G-Code Wiki here : http://reprap.org/wiki/G-code

A simple start could be :
G0 F100 X10
G0 F150 X20
G0 F200 X30
G0 F250 X40
G0 F300 X50

Which would turn the x motor in steps of 10 “mm” starting with 100mm/min increating to 300mm/min

Is that what you looked for?
