Question about Linistepper v2

[john_100]

Hi Simba77eg

as you have noted RN1 is 5 bussed resistors ,connected to a common terminal

RN2 and RN3 being isolated resistors


does this link help

http://www.farnell.com/datasheets/90452.pdf

it shows most variations of the resistor networks available

resistor networks are available in single in line and
dual in line packages

the advantage being ease of assembly , space saving and close matching of the resistors in the network

I can see no reason why you can't use individual resistors in the linistepper circuit

Individual resistors will be fine if you are building your own.

We changed to the SIL resistor packs as a service to the user, as they make it much faster and easier to build the Linistepper kit compared to individual resistors, which need colours reading, wire bending, inserting, wire snipping etc etc.

Thanks john 100...sorry been away for a while...actually using single resistors is what i did.
I finished building my linis plus the bob, now I am working on programing the PIC, It is my first time and I am having quit a hard time but i want to learn.
i will try to post photos for the finished boards.

Looks nice simba! If you get tired of trying to program them yourself, pre-programmed PIC's are available for a few dollars US.

Hi,

I made two different versions of linistepper v2 driver. The first was from Murat Shakman and the second from the shematic. Both of them not working.
If I connect the motor (I tried 2 motors) and power (6volts, 0.8Ampere)to the drivers the motor does not "lock" and of course not move.
Also I used the "4 axis BOB" from piclist com with the same results.
I meassured the voltage of A-, A+, B-, B+ points and give me everyone about 6volts.
I think the problem is at Pic16F628-20IP (it is working on an other project) programming.
What fuses should be used?
Thanks

The settings are listed in the source code: /Techref/io/stepper/linistep/Lini_asm_v21.asm

Thank you sir.
I didnt set the right settings to the software programmer. Finally I have two working linistepper drivers and I am going to make one more!!!
