Greetings to my probably saner friends on this list; My Z home switch is about 6" away from the chuck.
I have opened up the ferror settings so it can move about .1" before triggering a following error. I have also slowed the homing speeds up to a crawl. I am getting two errors reported. One names a non-existent in the man page if I enable what I think is the last data path from offset.0.fb-out to joint.0.pos-fb but the terminal complains about: 280: Signal 'bedwear6' can not add OUT pin 'joint.0.pos-fb', it already has OUT pin 'offset.0.fb-out' BUT ITS COMMENTED OUT!!!!!!! That net label bedwear6 is # disabled so it will at least run. I have the lincurve.0.y-val's alternated from -0.01 to 0.01 for about the first 16" of travel. Firing it up and initiating a homeing operation, x creeps out to eventually close its roller tipped homing switch, at that point jumping at the max axis speed of 30 ipm, an additional outward move which is just a few thou short of demolishing the switch and bracket. And its much larger jump than enabling the offset would account for. Thats problem #1 >From there it proceeds inward to open the switch as it should, switching to a somewhat faster move to its parking position about 50 thou off the switch when the switch opens, but its running slowly inward another 1/4"+ before stopping, at which point it surveys the Z switch, probably finds it closed so it runs to the right to open the switch. But it overruns the switch opening by at least 1/2", then reverses to find the switch closure, but when it finds it, it goes to the faster final move speed, but moves to the right until it errors with a joint.1.following error. It should be moving left to a point about 3" from the chuck, a distance to the left of the switch closure by around 5" Thats problem #2. So my question then, is when does this x comp move derived from Z via the lincurve begin to take effect in the homeing sequence? It looks to me like its enabled as soon as the x switch closes the first time. But to prove that, I'll go invert the signs of the first 6 or so y-val-nn's and see if x moves the other way when its home switch closes. I never imagined that putting in a lincurve, offset would turn into such a headache, compounded by at least 3 errors in the motion man page. I am about to go restore that whole directory to august 24th, the earliest backup I have because I replaced the amandatapes drive, a 1T, with a 2T without telling amanda to start from scratch, but that backup of picnc is a full level 0 backup so I can back up that far only w/o putting the old drive back in. That far back it was Just Working. I think it was before I started this whole damned circus with bad docs, so I'm not really sure what the hell I'm doing... That drive cage for this machine fell off the oxcart from kalipornia today, and I am quite disappointed, it holds 4 drives ok, but theres nothing resembling a quick change to it. Screwed just under $50 worth and I didn't even get kissed. However, by using the cables direct to the back of the drive, it will be bypassing the 3 drive cages iffy slot. Choose your poison carefully IOW. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
