Hi Chris,

Could be a noise issue - check that you haven't pulled off a ground connection cable somewhere.

Hey Chris,

Could you explain this a little more please. I am baffled.

It looks like the top photo has the toolpath running horizontal wheras the other photos look like the toolpath is vertical to the piece.
Surely if the stepover was the same then all phots would show the lines, wouldn't they ?.

Nice job SF.
Keep on grabbing ideas from the forum - that's what it's for.

Hi High Tech Key,

If you are switching your spindle on / off with a relay which does not have adequate arc suppression (across the contacts) then the noise spike generated may well crash your computer.

SSR's such as this one, switch at the 'mains zero crossing point' and produce much less noise. They can be driven from your existing relay and just require a small power source.

Hi Gaz,

I think it is like all the stuff from China - you don't know if it's any good until you have it in your hand.
Most of the stuff I have purchased from China has been of excellent quality, but not all, so beware.

Hi Jammerm,

Some litho's were made with Mach1Filter some with CamBam and others with Bmp2Cnc. BmpBender may also be suitable but I have yet to try this for litho's.

Looking forward to seeing the results from your machine.

Great stuff Robert.

Here is another one for you.

Some interesting Logo’s can be found at ‘Brands of the World’ http://www.brandsoftheworld.com/ and when converted to grayscale the Mach1Filter.exe program, which can be found here http://www.machsupport.com/forum/index.php/topic,6544.0.html makes for an interesting height / depth map for engraving, if you get it right.

Still you have to look at it this way - the cutters from China are cheapy cheapy and the more you break the more mouths you feed. Its called doing your small bit for the emerging nations.

Hi Robert,

Try using a different file name for your picture upload (a name that has not been used already on the forum) then it should work.

I am from the UK.
