I have had a play with altering the current and managed to get some movement but its jerky and not going in a constant direction but back and forth. I have also managed to get an oscilloscope on the clock pin and all looks good.by jhdgkss - Stepper Motors, Servo Motors, DC Motors
Hello i am building a stepper driver which is controlled my an Mbed microcontroller. The Stepper driver is an L6228 form ST. L6228 Datasheet I have constructed the circuit as described in the datasheet. How ever the motor will not step but in fact locks in position and makes a sound of pulsing. I am defiantly getting a pulse signal to the clock pin but still nothing Here is my Mbed code #iby jhdgkss - Stepper Motors, Servo Motors, DC Motors

Hithere iam building a repstrap but i am useing screw thred of the machine . is thede any repraprox. does the reprap softwre make any allowence for this type of set up i.e number od steps to distance travelled by tje cqrraige to drivethe axias sorry for the spelling i am typing on my phoneby jhdgkss - Mechanics
Hi there i am building my own repstap with a basic adriuno board with a set of pic based stepper motor controllers using a simple 2 bit input (of forward and back each pulse equalling to one step). How ever i am having to use threaded rod to drive my axis' as opposed to belts. My question is, will i still be able to use the standard reprap software to control my machine?by jhdgkss - RepRap Host
I think the best arrangment is to have the extruder fixed and use the robot as the table. Also increase the base of the bot this should help with resolution.by jhdgkss - Delta Machines
Hi there i found this video and thought i should post it. This robot seems very smooth and accurate what do you think?? Video here Delta robot videoby jhdgkss - Delta Machines
Hi there.( This is my first post here) My name is John i have been in engineering for 15 years, i have a degree in aircraft engineering and i am currently working on my next degree in electronic engineering. I have been looking into building a 3d printer for some time now that that could be built by the layman, and tried a couple of ideas out. But to be honest i have not been happy with any of thby jhdgkss - Delta Machines
