    Re: PWM/HPWM Stepper Motor Controller

    Mark, Thanks... yep they are just PVC pipe with end caps and a flange for 3/8" aluminum rod/axle. You can email me if you want some specifics on the parts I used.

    Re: PWM/HPWM Stepper Motor Controller

    I have not had a chance to work with the HPWM pulsing but I should soon. The past week I have been concentrating on getting the frame together for my small conveyor. Now that I have a more adequate...

    Re: PWM/HPWM Stepper Motor Controller

    Argh... RTFDS! David haha the 12F683 that I have been testing with has PWM in it whats wrong with me. I do have some 16F pics coming to give me more input/output which I know I will need

    Re: PWM/HPWM Stepper Motor Controller

    Henrik thank you I thought so. By the way if anyone is interested I got the power supply and dual dc/dc converter and they work beautifully. I have 24v for the stepper, 12v for the solenoids and 5v...

    Re: PWM/HPWM Stepper Motor Controller

    This is going to be a stupid question and one I could answer myself by just testing it but I will ask anyway. If the stepper is set to 1600 pulses per revolution and I send it 800 pulses I'm assuming...

    Re: PWM/HPWM Stepper Motor Controller

    Henrik, agreed about the need for the extra pins. I will be switching to the 16F series for sure I've already thought of the extra pins I will need stop/start, Jog, , manual speed, lcd, direction,...

    Re: PWM/HPWM Stepper Motor Controller

    Henrik, Thanks.... well that is going to be trial and error at this point. I actually am going to have to hook up my conveyer belt and use the pulse method I've been using so I can get an idea. i...

    Re: PWM/HPWM Stepper Motor Controller

    Mark maybe we can work this out together with Henrik's assistance. I went to the micro chip site and used their processor selector to find one that had the PWM built in. It looks like the 12F752 has...

    Re: PWM/HPWM Stepper Motor Controller

    Henrik, Thank you and thanks for your explanation. I've not done any work with the stepper motors so I'm still learning. I'm actually not trying to get much speed out of the stepper. I will be...

    I was thinking ahead a little bit and for now my testing has been to test the solenoid activation and stepper motor each by themselves. Now they will need to work in conjunction with each other...

    Re: PWM/HPWM Stepper Motor Controller

    I know we are getting a little off topic with regards to PIC's and Picbasic I hope that's ok my project overall is dependent on the PIC and the programming needed.

    Sorry about the noise in the...

    Re: PWM/HPWM Stepper Motor Controller

    Mark, so I have been messing around with the time and seems to work pretty smooth. I am running 12v power supply and have the controller set to 1.5a and 1600 pulse per revolution. It is very smooth...

    Mark, Never mind I got it... the 12F683 did not like ROTOR=1 and ROTOR=0 I needed to high ROTOR and low ROTOR
    it's spinning now going to try and make it smoother and faster mess around with those a...

    Re: PWM/HPWM Stepper Motor Controller

    I'm going to be driving a drive pulley for a conveyer belt so things will be going slow don't need a lot of torque or speed.

    thanks I will start off at half power and 200 rev's see how things go ...

    Circuit boards are in. I realize that this differs slightly from my schematic I uploaded. I added a PBO-1-S5 to the board to supply power and eliminate the need for a wall wart for power. The PBO is...
