o avoid accidentally moving MPG and axis, steps to delay the start of axis movement
can be set in plugin configuration table.
2.3.1 Pressing and holding the Quick Selection Button will temporally turn CONTINUOUS
mode to STEP mode. A matched feed rate as in CONTINUOUS mode will be used in STEP mode.

•Number in Step Jogging FeedRate is the feed rate only used in MPG step jogging. When
MPG wheel stops the feed rate and FeedRate Overridden rate (FRO) automatically changes
back to the number which was used before MPG moving. Set 0 to use current FeedRate and
FRO rate in the system.
•Numbers in Speed Change Sensitivity is used to adjust the sensitivity of V mode. The smaller
the number the less turns are needed to reach maximum axis speed.
•Steps to Delay Start is used to set the number of steps to delay to start axis movement. In C
mode axis starts to move only after that many numbers of steps are turned from MPG wheel.
•Velo ity In’s or mm’s Per min. is used to calculate feed rate used in STEP jogging in CON’T /
STEP mode. The number can be copied from Mach3 -> Config -> Motor Tuning and the
number need to be refreshed each time motor turning is performed.
•F1 to F5 buttons each has 62 functions to select:
