Stepper Motor Controller on homemade pcb

[sam19090]

you are skipping steps, you can make the motor go smoother and faster if you fill the rest of the steps your steps : 1100 0110 0011 1001 you need to do the steps: 1000 1100 0100 0110 0010 0011 0001 1001 good luck

@sam19090 - You mean gray code? Allowing only one bit change at a time?

[parravision2011]

how do you measure the speed the motor is running at?

[mvoerman]

@parravision2011 Should be easy. For example the motor rotates 1.8 degrees everytime you send a pulse. That means it will take 360/1.8 = 200 pulses to make one full rotation.

If you know how fast youre sending the pulses, you'd know how fast it the motor is running.

how did you know what parts you needed??? what are those chips for and do they have code in them?? :O

So, how goes the half stepping version? I made a board with a TTL half step sequencer on it. I'd post a link to a picture but apparently it is not allowed here. bitDOTly cS2xpO

this is good can you giving me a plan of this board thanks

[Pyroflea53]

Is this capable of half/quarter/eighth stepping, or does it only do whole steps? Thanks :)

[mvoerman]

Whole steps.. I am working on the half-step version right now...

I dont think smaller than half-steps can be achieved without a uC..

[Pyroflea53]

Alright, looking forward to seeing the next design :)

[spike2fei]

can it be plug in a pc

[mvoerman]

Yes , i designed it so that it can be hooked up to the parallel port

[kieuquang1305]

pleases give me the Ic Number
