Do you have movement in the correct directions now, i.e. positive X moves to the right and positive Y moves towards the
frontback? -
I've got the motors moving correctly now i.e. G1 S2 X10 moves print head towards the right and Y towards the rear. G1 S2 Y10 moves print head to the left and Y towards the rear,…...............................
That ain't right. If you command the machine to move in the X axis (G1 X10) then there should be no movement of the Y axis. Conversely, if if you command it to move in Y (G10 Y10), there should be no movement in X.
So assuming you have configured your printer to work in coreXY mode by having M667 S1 in you config.g, then it seems that you might need to swap the X and Y motor connections (with the power off !!!) then play around with the S values for M569 P0 and P1 until you get the motion correct. You can send M569 commands from the =web interface so no need to keep editing the config.g and restarting every time.
Also, just use G1 X10 or G1 Y10 and if you want with S1 to check for end stops. S0 is the default and ignores end stops. S2 I think is only for Delta printers.

Ian, if he is using the S2 modifier then the movements he said are correct. The S2 modifier allows you to control individual motors on both delta and CoreXY printers.

Yes, dc-42 motor directions are correct per the G1 S2 commands I send. Moving X+ manually also goes right by itself and moving Y+ manually sends the gantry away from me by itself. My biggest problem now I feel that I have something terribly wrong in my homing files preventing X and Y from searching out the endstops. I realize that I don't have the correct Y homing position entered at the moment. I believe per a previous conversation we had that it needs to be set to a positive number that correlates to front of bed. I've just gotten really hung up on why it wont search out the X and Y endstops per my homing at the moment. If I hit homeall right now, X travels 10mm to the right from whichever current position it's in and Y moves directly forward from the new X position and stops at the front of the bed. Z goes to the endstop, ignores it and tries to keep going.

Sorry, my bad - just what I read here http://reprap.org/wiki/G-code#G0_.26_G1:_Move only mentions Deltas' not coreXY.
Anyway, I'm a bit confused. The first post states that homing is to left rear. So if the motors are moving correctly, shouldn't Y+ be moving away from home -i.e. towards the front rather than away towards the rear?
-
The description of events when you press homeall and looking at your homeall.g fiile, seems to me that the endstops are permanently triggered as if they are wired active high but they are set to active low by using S0 in M574. Also, I'm a bit confused as to what you are using form Z homing. Is it a switch or is it a probe? - you seem to have both in your homeall.g file,
-
Z homing is endstop switch. It seems to me that regardless of everything, that if I go to the G code console in DWC and send a G1 S1 X-300 command that my X should go to the endstop, but it doesn't. As soon as I send that command, it immediately shows the X being at Home position.Yes, I've been wondering about those Z probe definitions and whether I need to comment them out. I've just had the Z endstop so far, but will be receiving the mini ir probe tomorrow and hope to implement it ASAP.

You need to use M119 to make sure the endstops are working as expected.
-
M119 shows;Endstops - X: at min stop, Y: at min stop, Z: at min stop, Z probe: not stopped. My print head is currently near the center of the bed and Z is about 10mm from nozzle.

You have your endstops inverted. If they are simple microswitches, rewire them to use the two outer connections on each switch (the normally closed contacts). Otherwise, change S1 to S0 in the M574 command in config.g. See https://duet3d.com/wiki/Connecting_endstop_switches.
Additionally, if your Y endstop is at the back of the printer then it is a max stop not a min stop, and you need to change Y1 to Y2 in your M574 command.
-
Endstops triggering all the time means you have the endstops wired (or configured) incorrectly as Deckingman mentioned earlier in this thread. Are they active high or active low? Do you have them wired appropriately? Does the M574 command match? You've posted two different versions of M574 in this thread, one with endstops active high, and one with them active low . Check which is correct as you have the unit wired and make M574 match.
EDIT: What DC42 said…
-
I wired my endstops per the Duet Wifi wiki:…...................Makerbot Mechanical Endstop v1.2
Thus is a small board holding a microswitch, LED and a few other components. Connect pin 1 of the endstop board to the 3V3 pin on the Duet endstop connector, pin 2 or 3 to Duet endstop connector GND, and pin 4 to Duet endstop connector STP......... This is wrong? My pin 1 is red wire. It's connected to the center pin on board connection. Pin 2 black wire is connected to ground on board. Far right pin on endstop, green is connected to "stop" pin of appropriate board connector. I went by this diagram[https://duet3d.com/wiki/Duet_WiFi_wiring_diagrams]…..... so I guess I need to swap out the positions of the black and green wires from how I have them? Correct? -
I'm sorry for any confusion I;ve caused anyone trying to help me. I'm new at this and sincerely appreciate the help. I've made adjustments to the M574 command and M119 now shows all endstops open(not stopped) and I still have correct movement when sending G1 S2's. X homes correctly now also. Only hurdle now is getting Y to home correctly
Once again, I sincerely appreciate everyone's help! -
If I didn't miss the things you have changed, your M574 command should be M574 X1 Y2 Z1 S1 since you have your Y endstop at the rear.
Have you changed your home scripts also? So that when you home Y it moves to a positive number towards the rear? -
As Jackal says. See the section that starts "For a machine with a homing switch at the high end, homex.g would look like this instead" at https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Cartesian_printer#Homing_files but apply that method to your homey.g file. So all the X parameters in that example should be replaced by Y.

It is accomplished gentlemen! Thanks again for e-one's help, especially you dc-42. I just received your mini ir probe today. Now to get it installed. Wish me luck!

Glad you got it sorted. Don't be afraid to post here if you have any other problems. We'll all try to help if we can although when DC42 posts, it is wise to listen to whatever he says.
