hi i have mach 3 and when machining something the speed of the machine is always the same.
is there any way that when running a gcode ,when the z axis raises to a safe position ,and the machine moves to next position ,that the speed can be faster ?
i dont know if this is call rapid move i´m a newbie.
it sounds like your max speed is lower than any of the speed called from your g-code... eg, if your max speed is 800mm/min and your g-code calls for 3000mm/min mach will rapid your machine at 800mm/min
whats the top speed you have set in motor tuning in mach?
i had a 14mm screw with 2 mm pitch , but this was before i dissassemble my machine.
now i´ve upgraded her with belts (15tooth around 12mm diameter) witch give me much more speed.
but i have not assembled the machine yet ,so i cannot tell you the speed setting now. maybe this weekend.
whem a have this assembled i´ll put my speed settings here so you can help me!!
thanks for the fast answer
ok im with you... you will need to exsperiment with your motor tunings to see what the machine will run at with the new fittings.
keep upping the top speed until your steppers start stalling then back off the speed by maybe 20%
you will also need to do some mathermatics to work out how may steps per unit and update that in motor tuning (you can do this automaticaly if you have a dti but its probably better to get the calculator out and do the maths:)
let us know if you get stuck :)
i think i understood what you said .~i´ve simulated a toolpath on mach 3 and i put a high speed rate and a slow feedrate ,and i saw the arrow on the display moving quickly
when changing position.
thanks men really apreciciate your help.
sorry if my english is not that good!
haha!! your english is great compared to my portugese :)
