hi,need some help,why the jog speed is difference from the machine speed.the machine speed looks slow compare to the jog speed.because the jog speed come out with a # of 9000mm/min.i know my machine only can run about 3000mm/min.can some one let me know where is the setting.thanks

there is all ok in the ini file
you shoudt keep the BASE Period at 100000 / 100k at below 200mm/sec
FOR safty reason enofh stepspace


DID you cut the max speed Slider
Almost Down in AXIS to the max
and the top Slider to 100 Percent

WEAR Behavior

Did you start with a frech stepconf or did you copy over to a new system

What is the System you use
Wheezy 2.7.14 recomended
Uspace 2.8 ???

If you jog with keyboard arrow keys, MAX_LINEAR_VELOCITY = 150.00 (mm/s) x 60 = 9000. I don`t remember if it is the entry in [DISPLAY] OR [TRAJ]. You have to try, lower one of those. If you can run run only 3000mm/min, some adjustement must be done anyway.

it is also not clear what he likes to say mashine speed
in G-code run or display
if all are set to 170 beside Z axis is 76 it shoudt run also the mashine without z move

if you get low speed at sculping or like woodwork plasma ...
you may ad a G64 P.2 to the G-code
this also can be a sign of to low steps between next point in order 0,1mm as the interpreter does only read up to 3-10 lines ahead
meaning it gets its next stop at iinternal below retching max speed rate

The scale of the Axis_ looks a bit strange, (the steps needed including microsteps for a move of 1mm). Could be the slow machine movement. Recalculate to confirm the entrys.
Set all MAX_LINEAR_VELOCITY and MAX_VELOCITY to 50
Or wait for advice from other specialist.

hi,thanks for the prompt replies.i think you misunderstand my question.or maybe i dont know how to express what i want to say.
actually my question is:
driver DM542
Nema 23 steepermotor
input voltage,36v
using lcnc 14
can it be running at 9000mm/min or higher?
because i saw the jog speed are9000mm/min topspeed ,but the table movement give me the impression is slower,it seem that it did not match 9000mm/min!So where can set it to match it both.thank you.

the max Velocity is up to your mashine setup and hardware
the m542 shoudt go beond 12m/min at 100steps/mm meaning 0,01per step

at 36V it is not the best PRESSURE better to go for 48V to get faster steprate

the Latency of your PC is also to considder

change MAX_LINEAR_VELOCITY = 150.00
to
MAX_LINEAR_VELOCITY = 200.00

and try this ini
Code:
[EMC] MACHINE = my-mill_start DEBUG = 0 [DISPLAY] DISPLAY = axis EDITOR = gedit POSITION_OFFSET = RELATIVE POSITION_FEEDBACK = ACTUAL ARCDIVISION = 64 GRIDS = 5mm 10mm 20mm 50mm 100mm MAX_FEED_OVERRIDE = 1.2 MIN_SPINDLE_OVERRIDE = 0.5 MAX_SPINDLE_OVERRIDE = 1.2 DEFAULT_LINEAR_VELOCITY = 15.00 MIN_LINEAR_VELOCITY = 0 MAX_LINEAR_VELOCITY = 200 INTRO_GRAPHIC = linuxcnc.gif INTRO_TIME = 5 PROGRAM_PREFIX = /home/deslee/linuxcnc/nc_files INCREMENTS = 1mm .5mm .1mm .05mm .01mm [FILTER] PROGRAM_EXTENSION = .png,.gif,.jpg Greyscale Depth Image PROGRAM_EXTENSION = .py Python Script png = image-to-gcode gif = image-to-gcode jpg = image-to-gcode py = python [TASK] TASK = milltask CYCLE_TIME = 0.010 [RS274NGC] PARAMETER_FILE = linuxcnc.var [EMCMOT] EMCMOT = motmod COMM_TIMEOUT = 1.0 COMM_WAIT = 0.010 BASE_PERIOD = 100000 SERVO_PERIOD = 1000000 [HAL] HALUI = halui HALFILE = my-mill_start.hal HALFILE = custom.hal POSTGUI_HALFILE = custom_postgui.hal [HALUI] # add halui MDI commands here (max 64) [TRAJ] AXES = 3 COORDINATES = X Y Z LINEAR_UNITS = mm ANGULAR_UNITS = degree CYCLE_TIME = 0.010 DEFAULT_VELOCITY = 15.00 MAX_VELOCITY = 200.00 [EMCIO] EMCIO = io CYCLE_TIME = 0.100 TOOL_TABLE = tool.tbl [AXIS_0] TYPE = LINEAR HOME = 0.0 MAX_VELOCITY = 200.0 MAX_ACCELERATION = 250.0 STEPGEN_MAXACCEL = 275.0 SCALE = 33.3333333333 FERROR = 1 MIN_FERROR = .25 MIN_LIMIT = -0.001 MAX_LIMIT = 1500.0 HOME_OFFSET = 0.0 [AXIS_1] TYPE = LINEAR HOME = 0.0 MAX_VELOCITY = 200.0 MAX_ACCELERATION = 250.0 STEPGEN_MAXACCEL = 275.0 SCALE = 11.1111111111 FERROR = 1 MIN_FERROR = .25 MIN_LIMIT = -0.001 MAX_LIMIT = 1000.0 HOME_OFFSET = 0.0 [AXIS_2] TYPE = LINEAR HOME = 0.0 MAX_VELOCITY = 76.0009052217 MAX_ACCELERATION = 100.0 STEPGEN_MAXACCEL = 125.0 SCALE = 198.511166253 FERROR = 1 MIN_FERROR = .25 MIN_LIMIT = -0.001 MAX_LIMIT = 100.0 HOME_OFFSET = 0.0
