Complete Board - 3 Axis + DC Spindle

[Ch_Irawan]

Hi,

Here is my work some years ago when I rebuilding a wrecked Roland PNC2300 CNC Engraver. It based on classic L297/298 with L6210 diode array. The interface can be via LPT port to PC or by a microcontroller on board, If parallel port is used then the microcontroller socket must be left empty. The board designed for a PIC18F452, but by piggy-backed the socket then other micro's can be used. It works nicely until now.

thank you my come handy
Would you have the code for the pic18f452?

Would you have the code for the pic18f452?

Sorry can't share that, the effort on it was just too great.

The board still could be useful as:
- a one board small cnc controller with parallel port interface software like mach x.
- a test board for anyone who want to build their own motion controller.

I am thinking to make some video demonstrating both cases, but it won't be soon as the videocam is not on me now.

I had difficulties accessing YouTube, uploading 20MB of another video is a nightmare. Any suggestion for an alternative?

what is the max amp draw on this board?

I just realize that one of my uploading attempts was actually successful, here is the video with MyCode on board.

The L298 spec is 2A continuous current, 46V max. As i remember on my board the current sets at 1.8A, while the voltage is 32V DC. The spindle driver use two H-Bridge in parallel, as per datasheet the max current for the spindle then becomes 3A continuous.

hi.
Mach3 ports & pins as a picture can give you.please

Mach3 ports & pins as a mach3.xml can give you.please

Just curious, why did you bother sharing the board layout and schematic if you're not willing to post the code to make the whole thing work? That seems somewhat counter-intuitive.

As per the info in his posts, the board is perfectly usable via the
parallel port interface, when using an external controller.
The microprocessor is needed if you want to make this into a
standalone controller - i.e, no PC, no MACH/EMC etc.
