Hi Craig

Just wondering about the CopyCat Wizard that seems to generate G-Code when jogging and pressing Feed Move button, not sure how you would save the readings from window but using a Webcam you can get a picture of what is on table.

I enclose a photo of a typical board, I don't have G-Code for this so if I wanted to drill I would mount on base, program some fixing points and then follow a line which I would draw on photo and mark each hole in the program also use different colour pen for different drill sizes on the photo, and then generate G-Code from this to drill.
I suppose you could do manually but would take forever on a board with say 1000 holes or more.

Hi Craig,

The camera thing is what we used to do when I was in Printed circuit industry in the 1980's fit camera on Excellon machine and after marking a path up on a Negative or Positive jog round and mark hole positions then save and run, no idea what language was used as its moved on a lot today using all Gerber files for PCB manufacturing.

Hi Craig,

I would be interested in the download link.

Also been looking for program to allow me to use a Web cam mounted in place of the Spindle motor so I can program co-ordinates from a PCB Negative Photo of board ( the old method before Gerber came along) and create G-Code, have you ever come across anything, Ive been searching but cant find anything.

Thanks again for Help

Regards John

Hi Craig

Okay done a dry run on that G-Code and changed a few parameters, and it works fine Ive not run spindle motor yet will try that on Monday, like you said added the G17 then changed R and P settings as they were to long and it goes through cycle brilliant.

Got to do mods to Y gantry as its to much movement the 8mm bars just have to much bend so getting 12mm supported and fix the Y gantry to the base so X axis moves and prob change the Y axis bars to 12mm bars.

Also found that need to add Probe script to set the Z high off a work piece, got that off a YouTube Guru.

The book is a very good idea but at £56 on Amazon will have to be a present, I think I have a fair understanding of this G-Code will learn more as I use more.

Hi Craig,

I realize that I will have to learn the G-Code it'll take a bit the old grey matter is not the same as when I was younger.

I have re-done the PCB Gcode from Eagle for the Timer PCB without any changes so you can see if there is any errors, all I will have to do is put the G17 at the beginning.

My CNC settings for "Z" are on the DRO 0.0000 at the top and goes down by about 2.75 inches so -2.7500, thats just before limit to limit switches.

I have a G-Code listing from CNC Cookbook so will use it to go through and try and understand what is happening.

Hi,

Just got a little bit lost with this G-Code I generated using from an Eagle design using PCB-Gcode, When running the code as in attachment,Commands "R0.1000 cause an error "R Less thanY in XZ Plane" this is in line 47.

G82 X-0.8000 Y2.4000  Z-0.0320 F20    R0.1000  P1.000000

Also what is the P1.00000  ,   "P    Serves as parameter address for various G and M codes    

    With G04, defines dwell time value.
    Also serves as a parameter in some canned cycles, representing dwell times or other variables.
    Also used in the calling and termination of subprograms. (With M98, it specifies which subprogram to call; with M99, it specifies which block number of the main program to return to.)"

 Can I delete both these command as R seems to relate to an arc.

Also stops on the "M03" command "To fast for pulley using Max" but carries on think that may related to spindle set at "S20000" which is not running on this test and is prob way faster than my spindle, so just need to edit as required..
