Alarm on UGS

[goldspade]

Hello,

I am new to CNC and I've been having some issues with UGS, it's been giving me the following alarm only when my soft limits are on:


[Error] An error was detected while sending ' g38.2 z-50 f150': (ALARM:2) Soft limit alarm. G-code motion target exceeds machine travel. Machine position retained. Alarm may be safely unlocked. Streaming has been paused.

[Error] Error while processing response <An error was detected while sending ' g38.2 z-50 f150': (ALARM:2) Soft limit alarm. G-code motion target exceeds machine travel. Machine position retained. Alarm may be safely unlocked


I do not know if it's the settings (listed below), 




$0 = 10 (Step pulse time, microseconds)

$1 = 255 (Step idle delay, milliseconds)

$2 = 0 (Step pulse invert, mask)

$3 = 0 (Step direction invert, mask)

$4 = 1 (Invert step enable pin, boolean)

$5 = 0 (Invert limit pins, boolean)

$6 = 0 (Invert probe pin, boolean)

$10 = 1 (Status report options, mask)

$11 = 0.010 (Junction deviation, millimeters)

$12 = 0.002 (Arc tolerance, millimeters)

$13 = 0 (Report in inches, boolean)

$20 = 1 (Soft limits enable, boolean)

$21 = 1 (Hard limits enable, boolean)

$22 = 1 (Homing cycle enable, boolean)

$23 = 3 (Homing direction invert, mask)

$24 = 50.000 (Homing locate feed rate, mm/min)

$25 = 1000.000 (Homing search seek rate, mm/min)

$26 = 250 (Homing switch debounce delay, milliseconds)

$27 = 6.000 (Homing switch pull-off distance, millimeters)

$30 = 100 (Maximum spindle speed, RPM)

$31 = 0 (Minimum spindle speed, RPM)

$32 = 1 (Laser-mode enable, boolean)

$100 = 57.288 (X-axis travel resolution, step/mm)

$101 = 57.288 (Y-axis travel resolution, step/mm)

$102 = 200.000 (Z-axis travel resolution, step/mm)

$110 = 16510.000 (X-axis maximum rate, mm/min)

$111 = 16510.000 (Y-axis maximum rate, mm/min)

$112 = 4570.000 (Z-axis maximum rate, mm/min)

$120 = 1470.000 (X-axis acceleration, mm/sec^2)

$121 = 1470.000 (Y-axis acceleration, mm/sec^2)

$122 = 700.000 (Z-axis acceleration, mm/sec^2)

$130 = 900.000 (X-axis maximum travel, millimeters)

$131 = 900.000 (Y-axis maximum travel, millimeters)

$132 = 95.000 (Z-axis maximum travel, millimeters)

Hope you guys can help.

The soft limit alarm on a probe command is thrown before the move, because IF the probe move were to go the full length of -50mm from your current Z position, then Z would travel beyond the machine limit as defined by $132=95, so that means the Z machine coordinate of your current position when probe is issued is -45.001 or lower.  In UGS, the DRO window shows the machine coord in smaller font and below the WCS coord.  The fix: Raise Z above machine coord -45 before you run your macro.

Also, I don't believe this to be related, but you seem to have grbl config settings for a Mega V XL, with the exception of the $23=3.  Mine is $23=1, meaning only X axis homing is reverse direction for factory recommended location of homing switches.  Did you relocate your Y and Z homing switch ?
