Endstop Not stopping Movement
ok I made the changes, but I still get the problem when the endstop is hit the machine does NOT stop. Is there something I can put in to stop the machine.
What kind of endstops are you using?
When you test them by hand to they show as triggered?
I have these endstops and they show as triggered in the screen when I press them by hand but it takes a few seconds to register. Is that normal?
Those are makerbot style endstops which are active high. It looks like you have them set up correctly in your config.g
; Endstops M574 X1 Y2 Z1 S0 ; Set active high endstops
Double check the instructions here. I had to swap the wires on mine.
I have not changed any wiring from 1.18 to 1.20 they has been only software. I have noticed though that when Homing X only 1 stepper motor moves and with my Core XY config dont both have to move?
The only changes to corexy are mentioned above. So if you've double checked wiring and adjusted for the changes mentioned and the motor tests move as expected and the endstops trigger properly by hand I'm not sure what else to say.
You say the endstop seems to have a delay in the DWC. Does the led on the duet itself also have a delay? Does the led on the endstop have a delay?
Would you suggest me going back down to 1.18?
For troubleshooting, sure give it a shot.
Remember to take into account any changes you've made during the upgrade. Ideally you have a backup of your configs from before?
So I dont have a backup of my config =(, but I am still when I send move commands it works as intended but when I Home only one of my 2 steppers move. I ran through the RepRap config file generator again and it gave me the same settings so I am not sure what to change.
Is there a setting that makes it not move both steppers as needed for CoreXY or does my machine think its in Cartesian mode when it Homes?
Is your config the same as your first post?
Here are my current config files
So if you command a Y or X movement in the DWC it will move correctly?
It's just homex.g that doesn't move properly? or do you mean the endstop doesn't trigger properly?
When I send a move command the machine moves correctly the issue is that when I issue a Home command on either X or Y that only one Stepper moves and does not stop when the end stop is triggered.

I see your problem.
; homex.g ; called to home the X axis ; ; generated by RepRapFirmware Configuration Tool on Tue Sep 04 2018 19:39:36 GMT-0700 (Pacific Daylight Time) G91 ; relative positioning G1 Z5 F6000 S2 ; lift Z relative to current position G1 S2 X-305 F1800 ; move quickly to X axis endstop and stop there (first pass) G1 X-5 F6000 ; go back a few mm G1 S2 X-305 F360 ; move slowly to X axis endstop once more (second pass) G1 Z-5 F6000 S2 ; lower Z again G90 ; absolute positioning
Your X moves to seek the endstop need to be S1, not S2. HomeY and homeall are ok. See if that solves the problem.
ok So I went and and made the changes and it did not do what I thought it would so I re-Tested my Direction settings
<code>; Machine configuration
M569 P0 S1 ; Drive 0 goes forwards (change to S0 to reverse it) X-Axis
M569 P1 S1 ; Drive 1 goes forwards Y-Axis
M569 P2 S0 ; Drive 2 goes forwards Z-Axis
M569 P3 R-1 ; Drive 3 goes forwards
M569 P4 S1 ; Drive 4 goes forwards<\code>
now when I test and change my P0 from "S1" my X-axis moves to "S0" my Y-Axis moves
I feel like I am loosing it. Is there a working config I can just buy from someone?
I think you misunderstood me. The S2 and S1 I was referring to are in your homex.g.
G1 S2 lets you move an axis that isn't homed. G1 S1 moves until an endstop is hit.
The motor direction settings in M569 will depend on how you have the motor wired, so there's no one config that will work unless the phases of the motors are also wired the same. But that's why there is the movement test for Core XY to verify that the motors are turning correctly. I think you verified they were?
I made the changes in my Homex.g and still only 1 stepper motor moved making the print head pull to one side the front left. So i double checked my Config.g to make sure my "X -10" moved towards my endstop. I then confirmed with the Y-Axis as well. As I switched the "S1" to "S0" instead of the X-Axis moving the Y-Axis would move.
Ok, so the endstop triggers now though right?
You should be using this procedure to test your motor movements for CoreXY
For a CoreXY or H-Bot machine, RepRapFirmware assumes that the motor connected to the X motor output moves the head in the +X and +Y directions when it runs forwards, and that the Y motor moves the head in +X and -Y directions when it runs forwards. [Note: firmware 1.18 and earlier assumes that the motor connected to the Y motor output moves the head in the -X and +Y directions when it runs forwards]. So you can start with these M569 commands in config.g:
M569 P0 S0 ; X motor runs forwards
M569 P1 S0 ; Y motor runs forwards
Then test for the correct X motor movement by sending these commands from the console:
G1 S2 X10 F3000
If the head moves diagonally in the +X and +Y directions, all is well. If it moves in the -X and -Y directions, change the S parameter to S1 in the M569 P0 command. If it moves towards +X and -Y, or towards -X and +Y, turn the power off and swap the X and Y motor connections.
When you have the X motor moving correctly, test the Y motor by sending from the console:
G1 S2 Y10 F3000
For firmware 1.19 and later: If the head moves diagonally in the +X and -Y directions, all is well. If it moves in the -X and +Y directions, change the S parameter in the M569 P1 command to S1.
For firmware 1.18 and earlier: If the head moves diagonally in the -X and +Y directions, all is well. If it moves in the +X and -Y directions, change the S parameter in the M569 P1 command to S1.
Important: make sure that you have chosen a right-hand axis system. That is, looking down on the printer the +Y direction should be 90 degrees anticlockwise from the +X direction. If instead it is 90 degrees clockwise, you have a left-hand axis system, which will give you mirror-image prints.
Ok so I ended up having to swap my X-axis and Y-axis motors (i did not think going from 1.18 to 1.20 would require a hardware rewire) but per the last post everything moves as it should.
The problem is still my homing files when i home x or why only that motor turns until its hits the end of the track and starts skipping teeth on the belt.

@sharpie I assumed you'd made the motor direction change after deckingmans first post way back at the start of the thread.
Now that you have that sorted I think the homing should be solved if you changed the the S2 flag as I mentioned. It should match the homey.g file which is correct.
The jump from 1.18 to 1.20 is a pretty big one. Always a good idea to read the release notes for major changes in all the versions between what you're updating from and what you're updating to. But now that you've made that jump the updates after 1.21 are pretty seamless.
