G-Code, CAD, and CAM discussions / Eagle & pcb-gcode help

« on: November 12, 2011, 06:54:17 AM »

Hello !
I have tried Eagle & pcb-gcode following example at
http://www.instructables.com/id/Turn-your-EAGLE-schematic-into-a-PCB/

I have generated the G-code and have a look to the result given by pcb-gcode and i can see problems with the toolpath generation:
there are some shortcuts !!
You can have a look to the joined files: i put a screen copy of the settings in pcg-gcode (it runs under eagle) and the result.
If somebody have some hints, they are welcomed !

Thanks

Hello,

i got a Rapid Collision detection by CutViewer but i see nothing wrong.
Can somebody help me ? joined screen copy of CutViewer with G-Code.
Does i need to define the tool size ? (already done with MeshCam).

Thanks

Thank you Gerry, i have seen this file but as it was a .m suffix i do not realized that it could be the G-code (as Mach3 expect .tap or .nc).
I will try this file with Mach3 tomorrow !

Hello !
1°_ I am trying MeshCAM trial version; i have generated a toolpath file but i don't see anything to generate the G-code (no index or button to do that !).
Can someone tells me how to do ?
2°_ i volontary choose an endmill which does not fit with my milling (end mill tool diameter 2mm & depth 8mm & tool queue greater than 2 mm & mill depth on Z is 13mm: not possible to do without breaking the tool !). Then i produce the toolpath file: MeshCAM does not detect anything wrong !!?
3°_ It seems that feed rate units is mm/min or in/min with MeshCAM; what is the unit used for estimate the CAM job time - is it seconds ? (i expect!)
4°_ I do not make real try for the moment because my CNC is not achieved yet. Do you have some feed rate experiences to give me - i set feed rate 100mm/min in wood
  & 20mm/min in aluminium for a 1/8in milling tool at 5000RPM - does it makes sense ?

Thank you for help

Hello,

I am a beginner.
i am using FreeCad for a mechanical part and have exported .ast file and now, i want to produce GCode for MAch3.
I have tried CamBam but the resulting .nc is bad for Mach3 (he doesn't recognized some words like "solid mesh").
What software can i use to produce Gcode ? what are you using ?

I have other questions - can you see the attached file (pdf) ?

Thank you very much for your help.

General Mach Discussion / MACH3 & Wine Ubuntu

« on: August 13, 2011, 01:05:48 PM »

Hello,

I have Ubuntu 10.04 & Wine. I have installed Mach3 R2.63 and i get several messages : "unable to register components C:\Mach3\VideoOCXTools.ocx; C:\Mach3\NTGraph.ocx &
C:\Mach3\SMTX.ocx"
I suppose Mach3 can't find it, which package is involved with that ? Is it Wine ? What are the name of the packages ?
thank you !
