G-Code, CAD, and CAM discussions / Re: need help

OK,

run through what you have done so far, what you have connected and where, what the hardware is and what you set up in Mach.

If you do this we can help.

If you are talking about this type of setup, NOT A CHANCE.

Hi Johann,

every set up is different and you have to set each motor to its optimum by playing around with the setting until you get it running nice.

My settings are :-

                        X axis                Y Axis                   Z axis
steps per mm -     800                     800                     880
velocity          -   1750                   1750                    2250
acceleration    -      55                       65                       50
step pulse      -        1                         1                        1
dir pulse         -        1                         1                        1

Try them but there is no guarantee they will work for your set up.

Poor circles are not always backlash, it could be badly adjusted slides and Gib strips,  it can also be flex in the machine or tool holder.

Check all of these and correct any problems, then set up the backlash in the screws.

Have you set the acceleration and velocity under motor tuning.

Works in progress / Re: New 4 Axis Milling Screen Set (RaspScreen)

« on: January 05, 2007, 06:31:55 AM »

Lots more to add yet but zeroing the dro's is one of them.

If you mean the opt stop led is flashing, I'm not sure why that is at the moment but I will fix it along with the rest of the problems

As I said its in a very early stage at the moment, but its always good to know what others think.  People come up with things I may have missed and after all the effort these things take its nice to think others would use it.

Works in progress / New 4 Axis Milling Screen Set (RaspScreen)

« on: January 05, 2007, 04:10:50 AM »

Hi All,

here is a part finished screen set for 4 axis milling, I have designed it to be clear, clean and simple, I am testing it for use on a 15" touch screen.

Put RaspScreen.set into the Mach3 folder

Put the RaspButtons folder inside Mach3\Bitmaps folder

PLEASE NOTE

The screen set is not finished and only part tested, load it and have a look but don't use it.

Any comments welcome.

Graham.

Hi Scott,

it must be me but I still dont see where the upper two bores are cut, the undercut tool moves in a square so what cuts the large bores?

You are right, there is a fault,  go in to the Artsoft website above and use Downloads and screen sets from there that seems to be working.
