Contraptor - plotter test

[casari4]

ciao ,

oggi ho scaricato il programma però non so dove trovare l'interfaccia per il computer.

mi potresti aiutare per favore=

molte grazie

This is nice, reminds me >20 years old ALFI plotter for ZX Spectrum from Czech Merkur construction set (see video yUmFYzyL9eo)

You need to implament some way of lifting the pen

[thedanishscout]

Awesome idea!

@baloneyjazz Arduino GCode Interpreter on Arduino. G-code from text was generated with shareware TTFtoDXF and Gcode2000 apps.

i know many faster ways to ruin a pen.

I really like Contraptor - it's a fantastic idea. Those RepRap drivers sound fairly horrific though. I think I'd rather use some micro-stepping drivers.

[albanetcsr]

I agree, the sound could be better. RepRap board only supports half-stepping at the moment. Keep in mind though - the stepper is $10, the board is $25 (kit) and open source.

Also, the set is modular and extensible, so any NEMA23 with alternative electronics are welcomed

@albanetcsr will reprap 2.3 drivers make less noise ?

[albanetcsr]

@karandex don't think so, they are also halfstepping

[demjp8RqDA]

@karandex For anyone new coming in, RepRap RAMPS 1.3 electronics uses Pololu drivers with up to 1/16 stepping and is said to be FAR quieter.

A Z axis is missing

[albanetcsr]

Yeah, it needs up/down electromagnet head like plotters have. It was a demo/test of the belt drive for the Contraptor project

Go on God with you

thanks captain obvious

[statusas]

how many arduino devices did you use?

[albanetcsr]

just 1 Arduino and 2 RepRap stepper driver boards
