@fcwilt M119 is reporting Y not stopped. The bed is forwards of it 60mm.

A Former User

@fcwilt DWC is reporting that when the bed is at the center of it's actual real-world run (228.6mm), it's at 220mm, which is the end of it's run.

A Former User

@fcwilt when I run the bed back to the y-endstop, DWC says the bed is at 104mm.

A Former User

@fcwilt how do we tell the firmware that 104mm is 0mm / home?

A Former User

@mac well, I guess that's the end of that.

Change to X1, Y1 and Z1. How did these get changed back? These were right yesterday!

@droftarts I guess I could scroll backwards through this thread to find out, but I don't want to blame anyone. I changed them, for whatever reason, so I'm the one at fault.

And now I've changed them again.

Here's the M119 report:

6/28/2022, 10:58:25 AM	M119
Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: not stopped

@droftarts what did that change accomplish? Is there something I’m supposed to do now? Would you like me to home the Y-axis to see if it stops at the endstop, then backs off?

A Former User

@droftarts my apologies to Frederick for pissing him off. He didn’t say anything to me; he just disappeared.

When you press them and send M119, they will say ‘at min stop’ now, assuming you restarted. Try homing.

I’m sure Frederick has just been distracted, not annoyed. I’m putting kids to bed, so away for a while.

The y-axis was set as M574 Y1 S1 P"!^i06.in". So it went towards the front of the printer, and when it got there it pounded on the front of the bed until I turned the printer off.

The end-stop for Y is at the rear of the machine, so, I changed the code to: M574 Y1 S0 P"!^io6.in" to send the bed backwards instead of forwards.

Now I'm going to give it a try, but first, I'm going to M119 the end-stops.

Interesting, Y: no endstop. At the bottom of the Console screen I'm seeing G28 Y Error: Failed to enable endstops.

Why would changing the direction of the bed from moving forwards to an endstop that isn't there to moving backwards to an endstop that is there cause the endstop to disappear?

I'll come back to his later.

Mac, you did not upset me in the slightest. My wife and I had made plans to go to lunch and the time to leave snuck up on me.

Lunch was grand.

Perhaps that will bring us luck.

@mac M574 S0 means no endstop. You change axis direction with M569. Again, this was fixed last night, so either you didn’t save it, or you’re using the wrong config.g.

Mac,

The M574 settings have no effect on the direction of travel. The merely specify the type of endstop (the S parameter ) and the location (the X, Y or Z parameter).

When you changed S1 to S0 you were specifying that there was no endstop on that axis.

S1 specifies a simple switch type endstop - which is what you have.

Change them all to S1.

The direction of travel is controlled, in part, by the settings in M569. Do you change those again. We had them correct, at least for Y.

The direction of homing is controlled by the G1 moves in the homing files.

For the Y axis a negative amount should move the bed backwards.

Example: G91 followed by G1 H1 Y-360

For the Y axis a positive amount should move the bed forwards.

Example: G91 followed by G1 Y+10

We don't need to worry about that now.

We have more fundamental problems with basic axis behavior.

That is what they are currently. Y is supposed to be going backwards. Does that reverse the jog buttons in DWC?
