@fcwilt It makes sense, let's go with it.

OK
This is next.
To use jogging of Y to measure the max travel of Y is simple:
- execute M564 H0 S0 (from the DWC console is fine) so you can jog the entire axis without being limited by the current M208 limits
- jog the bed as far back as possible
- execute G92 Y0
- jog the bed as far forward as possible
- read the current Y position as displayed by the DWC
When jogging near the ends try to "sneak" up on the ends so you don't over shoot them. The firmware will think the move happened even if the bed stayed still.

@fcwilt I'm going to follow your instructions, and I'll report them to you as soon as I have them. Just hang on, we'll get there.
-
@fcwilt Y is EXACTLY 350!

Does it seem possible that the bed actually moved 350mm?

@fcwilt THE FRONT OF THE BED IS AT 18 INCHES FROM WHERE IT STARTED.

@fcwilt 18 inches is 457.2 mm.

@fcwilt The bed started at 0 inches, and travelled to 18 inches. DWC called it 350.0. It's 18 inches. All of the numbers are whole numbers. We're golden.

But 18 inches is 457.2 mm - how is that possible?

@fcwilt I have an inches to metric calculator doing that for me.

No I mean if the bed actually moved 18 inches which is 457.2 mm the DWC should read the same 457.2 mm, assuming the DWC was reading 0 when you started. Which is should have since you execute G92 Y0.

@fcwilt maybe the question is, what is the relationship between DWC reporting 350, and my metal measuring stick reporting 18 inches?

When converting inches to mm the DWC should read out what you measured.

-
@fcwilt we have to subtract the depth of the bed!!!!! Which is 220. I'm getting 247?
-
@fcwilt so, how is 247 350?
-
@fcwilt 467-350 is 117. I wonder where that's coming from?
-
@fcwilt the back of the bed travelled 247 mm. The front did to. But DWC measured 350.0? That's interesting.
-
@fcwilt if DWC is at the center of the bed, could it travel 350.0?
