General Mach Discussion / Re: How do you go to "Z" or Home at 100% jog speed
« on: April 11, 2008, 11:29:11 AM »
need clarification on what you are meaning by "is there anyway to setup homing where, when you push go to z"
These are two totally different things, homing is so that you go to the home switches and then once there Mach knows its position and can then keep a track of it from there. Go to Z is moving all the axis to the offset zero position and is totally independant from homing. You may have your offset and home position at the same place which may seem like these two buttons do the same or similar thing but that is not the case.
As for slowing down to 10% then no I dont think it can be done. In a home move Mach doesnt really know where it is until it reaches the switch then the home position is set and softlimits can take effect from there. The softlimits that sshneider has mentioned wont really do what you are wanting either as they will slow an axis down as it gets towards the extremes of travel and actually stop it at your extreme so that you dont hit the physical limits. However it wont do this for a Go to Z (Go to Zero) move unless your zero position (offsets zero) is at your true zero (machine zero).
