MN400 Command Set

General: All MN400 parameters are 1 letter and are case insensitive. & indicates long integer. % indicates short integer.

Command Format: Command | data | data | data | data | data | data
There should not be any spaces and the data is delimited using a comma.
e.g. m10000,20000,30000,-40000

Command  Function
A centerx&, centery&, xdest&, ydest&, dir%
Moves tool along the path of an arc
B m1lash%, m2lash%, m3lash%, m4lash%
Sets the amount of backlash for each axis in steps
C port%, state%
Allows setting or resetting of the output ports
D m1lashdir%, m2lashdir%, m3lashdir%, m4lashdir%
Sets the initial state of the backlash direction all parameters are 1 or -1.
E m1&, m2&, m3&, m4&
Returns the total number of steps moved for each motor
F startspeed&, endspeed&, Accelrate&
Sets the ramping profile. Ramping is used during linear moves and jogging.
G res0&, res1&, res2&, res3&, step_per_inch&
Sets the number of steps to dispense upon jog button tap
H mode% (1 =shield mode, 0 = Feed hold)
Allows selection of shield interrupt mode or feedhold mode
 I mode% (0 - absolute (default), 1 - incremental)
Allows you to select absolute or relative mode
J mode%0 ( 1 = jog mode, 0 = run mode)
Places the controller in jog mode or run mode
L m1&, m2&, m3&, m4&
Allows modification of the absolute count kept in memory .
M m1&, m2&, m3&, m4&
Performs a vector move.
N
Returns number of steps not taken during previous move command.
P xmotor%, ymotor% (0 - M1, 1 - M2, 2 - M3, 3 - M4)
Selects the two motors to be used for circular interpolation.
Q
Abort move that is in progress.
R
Read the program stored in memory.
S
Reports the status of the limit and auxiliary inputs.
T m1&, m2&, m3&, m4&, pulses&, offset%
Allows linear moves to be interpolated with external pulses.
U
Runs a program stored in serial EEPROM.
V startspeed&
Sets velocity for linear & arc moves or sets external synchronization.
X multiplex%
Sets the resolution for multiplexing linear moves.
Z
Enables writing of program to serial EEPROM. Terminate by sending EOF command (^D).
? rev%
Returns the current software version number.
 *
Request response from all devices.
# rate%
Sets the baud rate to the selected value (0 to 3 for 9600, 19200, 38400, 57600).
