Next question...

After I set M669 K1 and run the CoreXY tests the motors run as expected. But running a simple "G91", "G1 H2 X10" results in both axis moving in plus direction. And "G1 H2 Y10" moves X+ and Y-.

It's always been that way on CoreXY machines, because G1 H2 moves are individual motor moves.

Well my homex no longer functions after changing S commands to H commands.

M400 ; make sure everything has stopped before we make changes
M913 X70 Y70 ; reduce motor current to 60% to prevent belt slipping
G91 ; relative positioning
G1 Z5 H2 F2000 ; drop bed relative to current position ; happens
G4 P250 ; wait 250msec
G1 X-300 H1 F3000 ; move quickly to X end stop and stop there (first pass) ; never happens
G4 P250 ; wait 250msec
G1 X30 F1000 ; Move Away 5mm X axis ; never happens
G1 X-35 H1 F2000 ; doesn't happen
M913 X100 Y100 ; motor current back to normal
G1 Z-5 H2 F200 ; drop bed relative to current position ; doesn't happen
G90 ; absolute positioning
G1 X20 F1000
M300 S600 P100

If I run Home X a second time nothing happens and I get a spinner.

@3dmntbighker That's odd. Homing works for me on my CoreXY using H1. Mine is a bit complicated because it's actually a CoreXYUVAB but the pure X moves are essentially the same as yours. The major difference I see in your file is the use of G4 which I don't bother with. Try taking those out. If that fixes it, you may have found a bug.

Edit, There is one other difference in my homing files. I don't use H2 in the Z move - I have M564 H0 in my config.g to allow moves prior to homing. So if taking out the G4 commands doesn't fix it, try using M564 H0 instead of the H2 Z move and report back (in case you've unearthed a bug).

Now X doesn't move at all after the Z move...

@3dmntbighker Sounds like a similar issue to https://forum.duet3d.com/topic/13409/large-core-homing-issue

It doesn't matter if I set X end stop active high or active low. The axis won't home (move) unless I hold the switch on, and stops when I release.

To clarify that, are you saying that you can change between S0 and S1 but the axis won't move unless you press the switch? What does M119 give you with and without the switch depressed?

To clarify that, are you saying that you can change between S0 and S1 but the axis won't move unless you press the switch? What does M119 give you with and without the switch depressed?

Correct

M119
Endstops - X: at min stop, Y: at min stop, Z: at min stop, Z probe: at min stop

Pressed:

M119
Endstops - X: not stopped, Y: at min stop, Z: at min stop, Z probe: at min stop

Also, after I attempt to home X nothing will move. None of the axis respond to the move buttons in the interface. Changing M574 from S0 to S1 gives the same result.

deckingman

@3dmntbighker So all the end stops are inverted. In which case changing from S0 to S1 should fix it. Unless you have unearthed a bug..........

Try using "!" to invert the end stops instead of the "S" parameter. i.e. M574 X1 S0 P"xstop" should give you one condition and M574 X1 S0 P"!xstop" should invert it. You want M119 to say "not stopped" normally and "at min stop" when the switch is pressed.

deckingman

Another thought.......you haven't got any M574 commands in your config-overide file which might be overriding config.g have you?

gtj0

@3dmntbighker Assuming you get the endstops configured, here are my working corexy homing files if they'll help. Notice I don't use H2 at all.

homexy.g gets called from homeall.g

Oops, forgot to mention... If Z isn't already homed, you'll need to add H2 to the Z moves.

Is the extra stuff at the end normal?

@3dmntbighker said in RepRapFirmware 3.0RC1 released:

I think the stuff after the T0 is just from copying from the DWC web page.

In any case, try putting the "M669 K1" at the top of the file. I don't think it'll make a difference but it may.

dc42

This is covered In the upgrade notes. S0 is no longer supported in M574. Use S1 and invert the pin using ! at the start of the pin name.

Yeah, looking at the file directly on the SD card it looks normal. I can enter M669 K1 in the console and no difference. It really seems to be an issue with M574? There seems to be no way to change the end stop from active high to active low. Changing M574 it always acts the same.

It's not noted in the M574 section of the RepRap changes document. Nor on the main G-code page. Which does have many notations about RRF3.

Thanks, I'm operational now. I had some issues with the Piezo sensor but I resolved those.

@3dmntbighker TBH, I didn't know that S0 had been withdrawn either. I was going by this thread https://forum.duet3d.com/topic/13136/m574-usage-on-rrf-3 where David said his intention was not to withdraw S0.

That's what we get for being bleeding edge. I don't ask for apologies

DC is "the man". He's done as much for my 3D printing as anyone.

dc42

Yes, I changed my mind. I found an inconsistency in how local and remote endstops configured using S0 were treated, and that led me to decide that providing two ways of doing the same thing was an unecessary complication.

Fair enough. @droftarts or someone needs to update the Gcode documentation to reflect that. https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_RepRapFirmware_Num_3
