Velleman KA03 - Arduino Motor and Power Shield

-

hello all,

i trying run nema 23 (12-48vdc, 4a, 23n in.oz torque) stepper motor controlled arduino using velleman-ka03 motor , power shield.

http://www.velleman.co.uk/contents/en-uk/p580_ka03.html

but velleman motor shield rated single 2.5a current supply need @ least 4a motor.

is there anyway can increase current output stepper motor velleman ka03 motor shield 2.5a 4a?

note: trying control stepper continuous acceleration , decelaration (sinusoidal motion without stopping/halting).

thank you.

that shield unsuitable stepper motor. not ideal stepper motor.

you need specialized stepper driver - example pololu drv8825 motors work 1.5 amps.

because motor needs 4 amps need more powerful (5amp or 6amp) stepper driver lot more expensive. google "6 amp stepper driver"

as far arduino concerned of driver controlled pololu drv8825.

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
