PIC Open source Servo Driver Schematics development?

[agelkom]

I made a single side PCB for Linistepper driver (Roman Black's) and add:
Over current circuit,
multiturn current trimpots for different type of motors,
Opto coupler for protecting pc's i/o,

Are you willing to share that design? Either here or at the Linistepper homepage for user modifications:

Of course, I will post it in a few days

Linistepper (Lini8) board and schematic files attached.
Please note that power transitor mounted bottom of pcb due to thermal runaway on large heathsink.

Hi,
Here is the PCB copper and layout pdf files for Linitepper Lini8. I can post if gerber files required.

tachus42 coud you please post the XEH files of your desing?
i'm not good in compiling codes

Hi Argun,
It's very interesting design. Coud you post the component list?

Hi Romas
The component list and schematic files for my Lini8 are attached.
A few important notes:
1. Darlinton Power transistor has protection diode however it is not as fast as schotky so that I add diodes.
2. R11A and R12A for optional
3. I also add D12 C7 J4 and R11 for current control when the "step" pulses are exist.
4. Power transistor mounted buttom of PCB
5. S1-2 Step , S1-3 Dir S1-4 Current control inputs S1-5 Over currunt output,
S1-1 input GND

Hi Argun,
Some components are mising in your component list (IC4, IC5, R11A, R12A, R46, R50-R52). Can you post full component list? Also I found discrepancy between schematic and pcb. In schematic resistor R51 attached to pin 4 of IC5, on pcb to pin 3. Can you check which is right?
Regards,
Romas

Hi Romas,
Sorry,
Component list attched.
R51 an IC5's photo diode are in series, there is no difference R51 position. The differences may occur during PCB drawing.

Hi to community (this is my first message here)

tachus42 > I' m interesting for your project, but I like to have info about LCD displsy that you use.
Can you propose a good type for this driver?

thanks in advance
