Hi Yoram,

Thanks for drawing attention to the Planet-CNC USB controller.
This board is available to buy complete or for those who can make their own PCB's, full constructional details (hardware, firmware and software) are available for the 4 axis version.

Don't rub it in - I know nothing of Lathes but I am a mean advocate when it comes to Routers.

Hi Chris,

Don't be intimidated by others stuff - you can do it just as they do if you are determined enough (although I would hold on a while before attempting one of Steve's V8's  http://www.machsupport.com/forum/index.php/topic,15091.0.html ).

I have made quite a lot of stuff that I really don't have the skills to make by conventional or manual means - all thanks to Mach3 and CNC.

"Tossers" I am really surprised at you Hood - They are called "Bankers", or at least it rhymes with Bankers

Reading is free but we all want help the economy so speed read and start spending.

Not sure about that Rich - We have been told that it is our spending that has got us into debt.

Hi Chris,

The "router" type of construction is ideal for wood and plastics.
The "mill" type of construction is ideal for metals.

Although each will, to a certain extent, do each others job it would not be ideal.

In general, home construction of a "milling machine" requires specialist machinery and knowledge so it is best to buy a mill and if necessary do the CNC conversion yourself. The "router" is relatively easy meat for home construction and requires a bit of skill but is not rocket science.

Hope this helps,

Tweakie.

G-Code, CAD, and CAM discussions / Re: G40, G41 and G42 have no effect.

Hi Jim,

I can only help with one thing because I apply the offsets prior to the GCode compilation.

I run G40 at the end of every program to clear offsetting. Does there need to be anything other than a line number, space, and then "G40" on the line?

You need a CR so it is usual to add  %  as the last line of any GCode. (not much but it's a start  )

General Mach Discussion / Re: CNC MISSING THE ODD STEP

Hi Jim,

Two things you could try;

Try selecting 'Sherline 1/2 Pulse Mode' in Config / Ports and Pins.
Try increasing the Debounce Interval in Config / General Config.

Your Kernel Speed should really be set to 25000Hz or 35000Hz.
The TB6560 is a good chip (assuming it is a genuine Toshiba and not a clone) so that Chinese board should be OK.

Going off topic and reverting to the fingers issue;

I have friends in the woodworking industry who have missing parts of fingers. It is perhaps surprising but they were not lost through lack of experience (one had 40 years in the trade) they were lost through complacency and familiarity with the machines they used and they will all say that they have no one to blame except themselves.

Take care Guys - It is not luck that keeps fingers it is vigilance.
