ok thanks
i didn't know if there is a possibility to create a variable for the feedrate then on each pass increase the variable by ...say 100. something like

feedrate = x
x= 1000

then on the next pass
x=x=100

Hi guys
i am in the process of building a new machine, this is 2meters by 1.8 meters, i have just set up the y axis and i am using rack and gear, i want the machine to run up and down a few hundred times to bed in the gears.
i have max'd out the motors , and i am getting a speed of 45 metres per minute without stalling or racking, of course i would never use this speed, but i just wanted to check to see how fast they will run at maximum, these are nema 23, 425 oz motors on a mod2 12 tooth gear and rack, direct , no gearbox. there seems to be plenty of torque in these motors,

what i want to do is start from the home position , y 0.00. and run it the full length of the bed, then return to the home position, pause for 2 secs so i can check the repeat position, then run back up at a slightly higher speed, and repeat about a couple of hundred times, this will help to bed in the gears and bearings, and also check for repeatability at the home position.


can anybody help me with the g gode for this please

thank you in anticipation

hi guys , new here, my name is jim

i have just set up a pc with mach 3 demo, i am in the process of tuninig the motors,  when i press the jog, the motor turns fine foe about 4 or 5 seconds then stalls or has a bump, it does not matter what speed i run the motors, i.e.: fast or slow i still get this "bumP', also on the feed rate window the the numbers dip slightly then go back to the run speed, even if i don't have the motor connected this same thing happens in the feed rate, it sounds like something is interrupting for a fraction of a second , but i have no idea what this is,  when the motors running they are very smooth and quiet until this point, the they.... bump and either stalll or carry on..........i have read some post with a similar problem, but have not found a solution to this......... antbody out there can help with............


best regards

Jim
