Hi! I'm interested in controlling 2 linistep controllers with a modified mouse. (The up/down wheel going to one controller, the side to side going to the other) How would I go about doing that? I am definitely going to order your kits, as I need something with very smooth operation.

Thank you very much for sharing this nice design!

To make it even more useful, it could provide a way to hook end-switches to it.

Maybe change the input scheme:
Inputs RA3 and RA4 are used to connect end-switches.
If either of both goes high, further steps in the current direction are ignored.
If RA3 and RA4 both get high, "programming mode" is enabled, and RA2 selects power mode, RA1 resp. RA0 serve as mode bits.

I'm not used to PIC programming, but maybe somebody is willing to implement this...

I see that there are 5 motor connection pins on the board.
The motors I have use 6 wires, because there is a common-A and common-B instead of a single common wire.
Should these be tied together when connecting to the board?

Thanks,
Kenny

Hi!

I'm very confident about the linistepper! I made two of them on one board, for driving two floppy drive steppers. It is for use of a dual axis telescope drive (1:3000 gear ratio). I have modified the firmware to support only the microstepping mode and your special halfstepping mode. Microstepping is very accurate and what is more important, there are absolutely NO vibrations, which can be even more distracting than rough step sizes. For controlling the stepper board, I have made a very simple controllerboard, based on an 16F84. It operates the two motors independantly and is also able to be controlled by RS232. It is adapted to be used for a altazimuth telescope. However, it could be interesting for other standalone operations as well.

Kind regards,

Kai Ries

Hi all,
Kai Ries, if your there, I would love to see the code for your alt-az telescope controller!
I can find no link to it :(
Please do post a link here if you wish to share it, you will save me and many others days of head scratching !
Many thanks,
Dylan.

The 1 0hm 3W resistors are for 1 ampere current limit. Is it nessecary to change these resistors when i want to use a motor with 0.6 current rating for one phase? Or can the driver with these resistors be used for any motor up to 1 ampere per phase?

http://homepage.ntlworld.com/janrose Hi to all! I'm very new to Pics, but have had excellent results so far with "burning" the 16f types, using source codes or hex files compiled by the experts "as is". The Linistepper looks fantastic to me, but I need some advise here. The project calls for a 16Mhz resonator. The Pic on the pictures seems to be a 10Mhz type. 1.Is this correct or am I misreading something?
2. Instead of using a 16Mhz resonator, can I use a 10Mhz crystal instead? (Got some in hand).
3.Most of all, I would like to use Pic 16f628, but of what freq? Does the source-code need modifying to suit? If so, what?
Thanks for the patience.. Can somebody please e-mail me directly..Regards, Jan Huyser
