Have a look in here; http://www.mycncuk.com/forums/227-Ro...es-Controllers top two posts look promising.

The second link gives me an idea as to what I should find when I finally take the to off the is that black box called a Bob.
the third link looks promising the control panel is identical,have not read it all yet.

No the BOB is short for break out board. That second link showing the Guts isn't what you have because it shows a USB Motion control card and you had Parallel port based box. The BOB will look very similair to the USB card in the picture.

NOW BE WARNED.!! Messing around with BOB without knowing the pinout and numbers is sure fire way to KILL it.!!
BOB's and esp a cheap one that will undoubtly be inside this box are fickle creatures at best of times so don't mess unless your sure what your doing.

Got it widescreen

There is a kind of problem I have, when I first got the Cnc going it was not that fast but liveable with, after calibration it now moves super slow fine for cutting but not from getting from a to b when not cutting. Surly if the original speed could be achieved to start with why can't it use it now, I tried travel speed on the mach3 screen with no luck I can slow it dow even more but not speed it up to its original speed. I can live with the speed if I have to but a faster travel speed between cuts would be nice.

the primary reason for buying the Cnc was for cutting carbon fiber sheet, I know that I need a diamond shaped cutting bit I got some from China but I think it would be better if I got them from America can anyone else suggest a place to get quality bits at not to expencive a price max cutting diameter 2mm also what rpm and cutting speed for diferent thicknesses of carbon.
to save the lungs I am going to cut the carbon in a water bath do you think building the bath deserves a thread of its ownas it is not a problem with the machine but a build project.
finally after seeing videos of wood being cut and when I cut a notch out of the leftovers from the base of the water bath I think enclosing the machine in a polycarbonate box would be a good idea a vacuum head with brushes is not always a good idea, a clear polycarbonate shield would be usful though.

Kendrick57 I am sorry but I find it very hard to read your posts as they seem to jump all over the place. I think it might be better if you address just one point at a time (ie one point per post).
Now if you can get your cutting speed (G1) as fast as you need then there should be no reason why you should not get your "travel" Rapid speed (G0) faster.
.
How about you posting some screen shots up of your Motor tuning from Mach3 and a short sample of your gcode ( say the top 30 lines) this might help to see what it is you are trying to achieve. ..Clive

ok one problem at a time.
The biggest problem I have I suppose at the moment is speed Now I never expected it to be super fast, the speed it went at when I first got it going I could live with but after calibrating the machine to move the correct distance(to start off with it thought 10mm was 31mm) the speed of the machine went from a tortoise to a snail. if the motors could move at one speed before the calibration it should be able to after.
It feels like a problem with speed of travel somewhere in mach3 the travel speed has been set at a set speed in mm per second.

MIRICAL APIFINY OR WHATEVER YOU WANT TO CALL IT
I solved the problem, it was in the Mach3 settings under Motor Turning in the config tab in the top menu


Its the setting marked in red that is the killer, it controls travel speed it was set to 120mm per minute I will keep increasing it until the gantry does not move any faster I've set all 3 axis to 999 the largest number it will accept, changing the acceleration number to a higher figure helps as well from one corner of the cutting area to the other by positioning by hand in the far corner with the other corner as home and hitting goto zero it took 43 seconds I think that is very respectable now I just have to confirm cutting speed is still ok.
Now I have the travel speed up to a good speed I can see the slower speed of the cutting speed.
