Formula: numerator/denominator=lead screw pitch X 1000/(360*subdivision number/step angle*
drive ratio)
Adjustment method:
1) set a ratio, such as 8/1, manually move a standard distance, such as 2000, measure actual moving distance,
use formula, 8*actual distance/1*2000, if the actual distance is 2651, then the simplified fraction is 2651/250.
2) set a ratio, such as 8/1, manually move a standard distance, such as 2000, measure actual moving distance,
press F key, input the value, press Enter, there is result, press F8 to confirm.
Note: automatic calculation is better.
Machine Origin: Set a coordinate point as machine reference point, or in manual interface to move the torch
to a certain position, confirm the origin position by F6 Test Origin.
Test origin: machine has mechanical zero point, and when reset direction is right, move the torch to the
selected position, set current coordinate, then press F7 Test Origin, execute “XY axis reset at the same time”,
then display XY axis current coordinate, press Enter to confirm, current coordinate is machine origin
coordinate.
Backlash: eliminate mechanical backlash, usually check mechanical structure, it’s better not to use backlash,
or easy to damage the machine.
Soft Limit: set a machine coordinate range, when torch moves beyond the range, reduce speed and stop, only
move torch in reverse direction to limit torch movement range to avoid torch collision, if don’t use soft limit,
can set soft limit invalid in Machine parameter.
Note: when automatically run, then stop after soft limit, automatically record break point.
Reset Direction: when set reset, torch movement direction is 1, torch positive movement direction is -1, torch
negative movement direction is 0, torch doesn’t move, when machine coordinate become X0, Y0, current
position is equal to machine zero point position.
