Have you taken note of the note below the picture?
Yes m8. I know about the drawing mistake.
I have made the board 3 times now. First ones soldering was a test and a bit messy (Wrong iron tip) 2nd had the same problem with the motor.
Did it again as i had used some parts recovered from my first attempt, and the picaxe I had was an 08 not 08m.
This time I did the board to fit neatly around my build platform and using motherboard pins for the connections along with phono jacks and the same problem with the motor.
The motor just will not go forward when told to, nor will it go back correctly once connected to the board (Sort of goes 3 forward and one step back or jiggles)
I can see it wanting to go through the focusing stages when I press Ch+/- and Vol-, all that happens is that the motor jiggles.
I have tested this motor through all 24 combinations of the 4 wires and I can get the motor to perform correctly, both CW and CCW with the battery test so it isn't that. I bought this second motor thinking my first one was faulty. So i got 2 motors and enough spare parts to make as second one for my son, if I ever manage to get this one going.
So to re-cap.
My board is good as far as my soldering and connections to the points of the board. Multimetered to make sure no lines are soldered together. The cuts/breaks are made in he board under each chip (used a 3mm drill bit by hand)
Parts are all new.
My board is the right way round.
The motor/s are good.
The picaxe was bought from tech supplies and had program uploaded to it with no problem. (08m2 not 08m, couldnt get 08m from tech supplies and got an 08 by mistake off fleabay first time)
The Darlington is the uln20003a as suggested. Bought through fleabay(I have ordered another 2 from tech supplies in case that is faulty?)
The 4n25 is one thing I wasn't totally sure of. Does it matter which way round it goes? I have mine with the + on line 20 as it was marked with the + end Correct? It wasn't indicated in the drawing.
That is about the story of it all.
I am going to try the new darlington when it comes to see if that helps.
Has anyone used the motor I have bought from Tech supplies? Do you know the correct sequence?
I found 6 sequences of the wires that seem to step the same size steps in the same direction. 3 forward and 3 back.
Any help I can get will be greatly appreciated.
Thanks.
