Re: dfx2gcode support...?

Examining the G code output from Dxf2gcode, I find that the X and Y axis values are specified in inches (which is what I am working in), while the Z axis is specified in millimetres. So, for a 1" square cut where the cutter is required to raise itself by 1", I have G code giving x -1. Y -1 and Z -25...

I'll have a look through them and see what can be done, then. Thanks...

Re: How do people handle the lack of tool radius compensatio

The CAM that you use to create the tool paths should handle the cutter compensation. If your current drawings are drawn to the actual scale you want, then you should be able to import the DXF files into a CAM program and the CAM program will handle the cutter compensation when it generates the G co...

Re: How do people handle the lack of tool radius compensatio

My 'plans' are in an old proprietary CAD package format. They are 2-D line drawings of parts to make model boats. I can output them as .DXF - and then I use DXF2Gcode to generate the cutting commands. Are you saying that the drawing package is the correct place to handle tool radius compensation? Th...

Re: How do people handle the lack of tool radius compensatio

Ah... all it seems to do is embed G41/G42 commands to the GRBL - which, of course, won't work.... And G Sharp just looks like some code libraries...

Re: How do people handle the lack of tool radius compensatio

I'm not sure. Being a beginner at this game is like exploring Africa in the 1850s - there are no maps and you have to discover everything for yourself. When you spoke about handling tool radius compensation outside GRBL, I looked at DFX2Gcode, which is what I am using to generate G Code, and I think...

Re: How do people handle the lack of tool radius compensatio

This would be something you would use instead of G Code Sender? If it supports macros then I suppose the user should be able to write their own compensation routine even if it is not natively supported. That would get round the Arduino limitations for GRBL. I was wondering if someone had ported GRBL...

How do people handle the lack of tool radius compensation in

I have a large number of cad 2-D plans, and eventually got an eShapeoko to cut them out accurately. But it uses an Arduino running GRBL, and this turns out not to have tool radius compensation. It would be a huge job for me to redraw all my plans - created over many years - all slightly wider. But i...

Re: GRBL Homing Glitch...

Hmmm.... STILL ignores the limit switch. But at least I know how to restart the machine now......

P.S. Now that I can restart the system I was able to sort out the limit switch wiring, and I got it to Home. Success!!

Re: GRBL Homing Glitch...

...and now I think I see the problem. $X means 'Unlock'. Which needs to be done after an error, even if cold booted. Who would have thought it, eh?

One more issue solved...isn't learning fun... :D
