[Sherlock Holmes wanted] Y-max endstop problem / RH coordinate issue
Hey everyone,
I got pissed that I could not figure this out. I have a Y max end stop, in the back end of the printer (connected to Y max on the Ramps board)
Homing seems fine, printer touches what its supposed to, the problem: RH says that after homing my Y coordinate is 0, where it is supposed to show 180 (my max y length), is that correct?
At first it would not move towards the front at all, since RH thinks its at 0mm, if I told it to move "up" (towards the back further) it would not go anywhere since the end stop is pressed, but the coordinate in RH would increase. THEN if i moved backwards, the print head could start moving towards the front.
[EDIT]
Now I uploaded a different set up, homing seems OK again, but coordinates are still all showing 0. where y should be 180, or am i wrong here?
Because now, if i tell the printer to move by 1mm towards to the back end, it goes all the way to the front immediately (very scary) and the coordinate shows 1mm. Perhaps its supposed to work this way... ?
Another issue appeared: in manual mode, if i tell the extruder to move 200mm in x direction, it goes to 160mm (my maximum distance for x), but again RH shows the coordinate as x=200 (and the coordinate is black??). Now if i tell it to move to x=5mm lets say, it goes all the way to the end stop, hits it (obviously), but in RH the coordinates remain BLACK (how the hell is that possible?) Same kind of situation is possible for Y as well. BUT if I tell it to move to x=250, the coordinates become red. extruder still stops by it self at x=160 (in the real world)... this shit if driving me insane. help me some one..
by the way this is my end stop config (plus home dir lines) if anyone interested
