My Range is -9999 - 9999

You can set up home search speed to 0. So linux cnc think A axis was himed.

No luck. In stepconf on the A setting page the last three lines to enter search speeds are NOT grayed out but the values cannot be entered or changed.
using V 2.7.15 Being 75 years old doesn't help. I know nothing about Linux but enjoyed Linuxcnc. I have been away from cnc for about ten years and trying to improve my hobby of using Linuscnc. Carl

Hello, you have to do this in the ini file.....

like this
Code:
#****************************************** [AXIS_B] MAX_VELOCITY = 250.0 MAX_ACCELERATION = 3500.0 MIN_LIMIT = -999999.0 MAX_LIMIT = 999999.0 [JOINT_4] TYPE = ANGULAR HOME = 0.0 FERROR = 0.5 MIN_FERROR = 0.05 MAX_VELOCITY = 250.0 MAX_ACCELERATION = 3500.0 # The values below should be 25% larger than MAX_VELOCITY and MAX_ACCELERATION # If using BACKLASH compensation STEPGEN_MAXACCEL should be 100% larger. STEPGEN_MAXVEL = 315.00 STEPGEN_MAXACCEL = 7000.00 P = 1000.0 I = 0.0 D = 0.0 FF0 = 0.0 FF1 = 1.0 FF2 = 0.0 BIAS = 0.0 DEADBAND = 0.0 MAX_OUTPUT = 0.0 # these are in nanoseconds DIRSETUP = 10000 DIRHOLD = 10000 STEPLEN = 5000 STEPSPACE = 5000 STEP_SCALE = 111.1111 MIN_LIMIT = -999999.0 MAX_LIMIT = 999999.0 HOME_OFFSET = 0.000000 HOME_SEARCH_VEL = 0.000000 HOME_LATCH_VEL = 0.00000 #HOME_FINAL_VEL = 0.250000 HOME_USE_INDEX = NO HOME_IGNORE_LIMITS = YES HOME_SEQUENCE = 3 #******************************************

Still no joy. I have it back working on 3 axis so I can use it. I have downloaded version 2.8.4. When my hair grows back I'll update/upgrade. Thanks anyways. Carl
