my thread rod is 1l4 , 1/8 deg stepper motor ...


I don't know why the size of actual cut is not same as i measure using my digital metric caliper ,,

toolpath from vcarve,, i mak square y axis 50.0mm and y is 50.0mm ,then i open the gcode to mach3 and i start running and finished the cut of square shape. the different is my square is to much for 50mm ,it become 80mm and the x axis is decreasing to 30mm

motor tuning step per is 200 and velocity is 135 x,y,z how to fix this >>>

The diameter of the threaded rod means nothing, you need to know how many threads per inch so you can calculate how many steps per inch.

So... how many threads per inch/ MM is the bar-stock?

If you have a Stepper with 1.8 Deg step-angle it takes 200 steps for one revolution, if the bar-stock has 16 threads per-inch it takes 3200 steps to move one-inch.

Your setup maybe wrong.

The thread rod is from any hardware store here and i measured the actual size ,this 5.9mm or 6mm include the bar-stock and TPI i measured total diameter is 6mm or 5.9 ,real size display in store is 1/4 .


200 steps per x 24 TpI = 4800 steps

Motor Tuning Before is 200 steps per > because in the label of the stepper motor is 1/8 deg,, Now i put 4800 steps per

high frequency is getting out from motors and not moving at all, it should stay to 200 step per
