Hi Les,

I doubt I'd be able to do that. The motor just sits there vibrating; never mind getting it interfaced to a compass!

Still no luck. I shall try output 2, perhaps output 1 is blown.

Cheers,

Alright. I connected it to motor output 2 and everything seems ok. Output 1 must be faulty.

I do, however, have another issue. When running the chronograph script, the motor will "skip" at random times, ie will move back a few steps then continue forward.

When testing using IOStepper.exe however, the motor moves freely without any jerks.

Cheers,

Jack

Jack,
I thought you said you were using iostepper along side Sioc. If you are trying to use ONLY sioc i was not happy with what i tried. However skipping maybe due to incorrect speed. Try altering this. Also try the compass code i gave you. In case there is somenthing screwy with yours. It works perfectly on my motor.

Hi Les,

I AM using BOTH SIOC and IOStepper.exe, not JUST SIOC.

Good idea about the speed, perhaps I shall alter it. Can the speed value be "too slow", or is only only too high-a-value that causes skipping?

I will try your Compass script to see if I still get the issue.

Cheers,

Jack

I think you have to find the sweet spot. Differs depending on your motor.

Hi Les,

I am now using a Unipolar motor and it works absolutely perfectly. Very, very smooth.

Further good news: I have implemented the Chronograph script and it also works absolutely perfectly.

This is the script:

Var 0112, name Switch7, Link IOCARD_SW, Input 222 // EVAC Toggle Switch
{
IF &Switch7 = 1
{
&BlinkLed = 60 // begin value of timer
&BlinkLed = TIMER 0 -1 100
}
}

Var 0000, Link USB_STEPPER, name Chrono, Output 3, PosL 240, PosC 0, PosR 4, Type T

Var 6, name BlinkLed
{
L0 = &BlinkLed
L1 = 60 - L0
&Final_Value = L1
}

Var 7, name Final_Value
{
L0 = &Final_Value * 6.00
&Chrono = L0
}

It literally just converts the seconds value into degrees for the Stepper motor to use.

For now, there aren't any more problems.

Thanks so very much for your help Les, and also to David!

Cheers,

Jack
