Greetings everybody; I think I've got the coolant pump starting problem fixed. Ignore that faint knocking sound.
Now I would like to use a teeny little pushbutton (6x6x2.5mm tall) between two solid parts of this machine for home and potentially as limit switches. However the amount of available overtravel after the switch has clicked is quite limited unless this switch is mounted on something crushable so that the getting stopped overtravel does not crush the switch like a Coors can. Is there a way to determine how much overtravel vs approach speeds is occuring? I ask because a wide open x or y move can do around 220 ipm on this machine, and that stopping distance is not an ignoreable distance when the switch only has maybe .010" of overtravel after its clicked. So I first would like to determine the maximum safe SEARCH_VEL I can use for homeing, then from that, be able to set MAX and MIN LIMITS far enough away from the crash stop to provide crash protection in the space between the LIMIT set in the ini file, or how much crush room I have to build into the switch mount? Also, in attempting to minimize this stopping distance, what or how can one detect a motor step slip if the ACCEL's are stopping the motor faster than it can stop? Hopefully without pounding a $90 dial into junk. Thanks all; Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
