I just love little engines and that is a beauty. Can't wait to see the next one.

Nothing wrong with self made machines Robert. 

Looks like you have rounded the tops of the letters which would suggest that your motor tuning settings need adjustment. Try increasing the acceleration and reducing the velocity (small adjustments each time and try the result). Reducing the overall feedrate may help. The problem would be sorted by operating in 'exact stop' mode (general config - select exact stop as opposed to constant velocity) but this would slow the progress of the overall work quite considerably.

Something else you may be interested in is this online utility for scaling GCode. http://www.eng-serve.com/cnc/gcode_scale.html
(By scaling 25.4 it will convert mm to inch).

I think we probably all learn by tweaking everything until it can be tweaked no more.

btw. Good work on the HD logo, it's early days yet.

Hi Robert,

Next to the DRO for each axis is it's 'Scale DRO'.
They are currently all set to 1.0000 - clicking on one highlights it, typing in 0.5 and pressing return then makes that axis 1/2 size, (0.25 = 1/4 size) etc.
Clicking on 'Toolpath' screen button and then 'Regen Toolpath' button will show the new dimensions in the 'Program Limits' box, change screen back to 'Program Run' screen and readjust scales as necessary.
You will be an expert before you know it

Hi Robert,

Ahh the quirks of LCam and the way the toolpaths are created. It would need a bit of work to optimize.
In the meantime try this GCode - scale it to your requirements using the DRO Scales as it is again in mm.

Don't know how you think of these things Chris.

That's truly beautiful work - You have certainly built a machine to be proud of Gary. Hope to see lots more projects soon.

OK Robert you are quite right this is the only way to learn.

Here is the DXF, it was produced in millimeter units but you can scale it to your requirements. Takes a couple of minutes to load in LazyCam. You will need the licensed version of Mach because it is a large file but see what you can make of it and let me know if you have any problems.

Hi James,

Next question - Can you be more specific on the user interface requirements you want to customize ?.

Is it just the screen display (button function etc) ?.

nb. I am in south east UK you can email or pm me if you prefer.

Hi James,

As all the required information required for customization is available somewhere on this forum it really can't be that difficult a task to do.
Perhaps if you give some idea of your location in the world there may be a member nearby who can help you.

Hi Glen,

Don't suppose you could send some of your surplus heat over here could you ?. Then I could get rid of some of the brass monkeys which keep coming to my door wanting soldering jobs.
