Yes unzip and replace the original.

well that did the trick o.k Jazz. at least i have the motors turning which was a great milestone to reach. i have to play with it to day to get comfortable with the different noises and speeds . i thought i had a problem with having only 3 inputs available because i couldn't use input 10 or 11 .......... turned out that they only become available for use when the dedicated inputs on the bob are wired in!!! every day is a day for school!! cheers for that last night , by the way.

Erm that sounds dodgy.!!! Lets just be clear for those dirty minded types.!. . . Last night wasn't pyhisical people. . .

Glad your working now get on with making chips.. .

i had my motors tuned to 2000 steps /per in the motor tuning section and slaved the A axis . the speed and aceleration were also set at a comfortable value, lovely , i thought. i put a dial indicator on the axis and set the code with a G0 X10 but it went at least 50mm.. 60 mm so i set the steps per unit on the settings tab to bring it in to tolerance but that then throws out my ''steps per'' in my motor tuning menu.... obviously the machine travel has to be right , am i missing some setting? the motor tuning ''steps per'' is now at 160 , a far cry from 2000 .

No I think your misunderstanding how it works. The steps per is how many steps required to move 1 unit. In your case 1 MM.

So you take the Micro stepping amount set in the drive and divide by the pitch of the ballscrew. So if you have 160 in "steps per" and it's moving correct distance then your using 1600 micro steps and the screw pitch is probably 10mm. Or your using 5mm pitch screw and 800MS.?

correct on the 1600 microstep , i misundersood because i got too happy with my self and the setting at 2000 steps/ per. i will surely find the sweet velocity and acceleration values when machining different materials. cheers for that.
