soft limits z axis mach 4
« on: February 24, 2017, 06:34:03 PM »
hello
z axis behaves strangely. i set it up soft min -5.00 soft max 0. home offset 0. i have also set it up soft max -.125 and home offset -.125. i have also set it up home offset .125 this worked even though it seems wrong i want to set z to move -.125 off the limit it doesnt seem to do this. if i set to home offset -.125 and home my machine will crash z if it doesnt it will still not work right. to me home offset -.125 makes sence if anybody has a fix or an explanation of why this is please. i am running a bridgeport stepper knee mill with ethernet smooth stepper and a cnc4pc c62 break out board thank you

hi i just figured it out!! the home offset is a positive because it is over machine coordinate zero the distance off the home switch is positive. reply if you differ.
