I could use some help
-
@fcwilt Interestingly, Y is saying 0.0
-
@fcwilt I did it again, now Y's saying -10
-
@fcwilt I changed the end to Y-20. The bed went towards the rear 20mm. Y is reporting -30mm.
-
@fcwilt according to my measurements, and my inches to millimeter calculator, if I change the number to Y-92.075mm, the foot of the bed will touch the end-stop.
-
@fcwilt hmmmm, the bed's being weird. I'm sending G1 H1 Y-92 , but the bed is inching towards the end stop instead of going straight for it.
And Y is now 0.0 again, whereas it was -30.

This post is deleted! -
@fcwilt okay, I've gone back to telling the board to move the bed back 10mm at a time (Y-10). It's working again. Y is at -10.0. It's also (I jogged it twice more), about 5mm from the end stop now.
-
@fcwilt I've moved the bed back to the center of the 452mm's. That's 9 inches (of 18). Y is reporting 100.00 now.
-
@fcwilt I have to run an errand. I'll be back in an hour.

The change to Y=0 should be because the endstop was triggered.
The post move behavior of a G1 H1 move is to set the axis position to the min or max value specified in the M208 for that axis.
Since the endstop for this axis is specified to be at the low end, the min value is used, and that is just what you are seeing.
Was the move, while slow, smooth and even?
It could because you did not specify an F parameter for the move. In that case it uses the speed set by the last F parameter that was executed.
You could try it all again but this time include, say, F3600 in the G1 H1 moves.

Hey mac,
What am I seeing?
Did something work as expected for once?

Hey mac,
Nice but G1 H2 is not the same as G1 H1.
To make use of the endstop for homing, you have to use G1 H1.

@fcwilt yep one down, two to go.
-
@fcwilt of course there has to be something weird going on.
I changed the H2 to H1. When I hit SEND, the board went back a bit, then stopped. So I sent the instructions 3 more times to get the bed all the way back to the end stop.
So H2 makes the bed home as is expected. And H1 does something unexpected.
-
@fcwilt the printer's back to its old tricks. It's pounding on the front of the bed when I tell it to home. I'm just trying to get it to do what it did, and it's telling me something I won't write. I'm thinking the same thing towards it.
