I could use some help
-
@fcwilt Okay, I'm going to change X and Y to 100.00 each. Save, reboot, and then Home Y.

Fingers still crossed.

@fcwilt Okay, Y started out very slowly, and went towards HOME (the rear of the printer), but stopped 89mm from the end-stop.
I'm sorry, Frederick, it's just not happening.

And yet jogging Y is now yielding correct distances?

@fcwilt The nozzle is 51mm west of the front of the bed (the back of the printer is pointed west).
-
@fcwilt I haven't tried to find that out yet. I'll do that now.

OK back to my previous question.
With the new value of 100 are Y movements done via jogging moving the correct distances?

@fcwilt I have an American tape measure going from the front of the printer to the back rail, where it's hooked on to the back rail. What I'm doing is bringing the adjustment wheel for the left corner of the bed to 10 inches. I just watched the bed move from 10 inches to 12 inches twice. So the bed travelled back and forth 51mm twice.
-
@fcwilt they appear to be consistent.
-
@fcwilt okay, I did a test. I clicked on Y-50 twice. That took the rear of the bed to the endstop (it hit it, versus touching it and backing away).

I don't care about homing Y right now because we know it is not working.
I need to be sure that Y movements done via jogging are now moving the correct distances.
Once that is assured the next step will be to determine if the current min/max limits for the Y axis are correct.
Why? Because I based my Y homing code on them. If they are wrong the homing code is wrong and will not work.

What appear to be consistent?
-
@fcwilt I'm looking at the Status window? Y is currently at 34.5.
-
@fcwilt I just moved the bed FORWARDS. Y is now at 124.5.

Where did the test start from? The fact that -100 took the rear of the bed to the endstop tells us nothing without knowing where the bed started from.

You cannot trust those numbers until you are absolutely sure the 100 is the correct value for Y in M92.
If M92 values are off everything the printer "says" and does will be off.

@fcwilt okay, here's something, I moved the Y-axis as far forwards as it would go. Status is saying I'm at 220.00.
The nozzle is 59 mm in front of the rear of the bed. So, for the nozzle to be at the back of the bed, the front of the bed has to go another 59mm. At which point Status should say Y is at 279.0.
-
@fcwilt I understand what you're saying about how the numbers have to be exact. Being close would be a good beginning to that journey, I think.
-
@fcwilt I just moved the nozzle to where I'd like the front of the bed to be. Status is reporting 62.0. I moved the bed as far forwards as it would go. I'm at 220.0 according to status, but I have another 59mm to go.

@fcwilt im sorry this is so frustrating. For me as well. But based on what we’ve learned, I’m starting to see the problem spatially. So that’s helpful, to me, at least.
