On a different thing would you say it is better to have the dual a setup so it will level the bed or is it more aggravation then it is worth the time of setting it up ?

Do you mean this? https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors

It's not too difficult to setup, and if you are using 2 seperate Z motors anyway they are bound to get out of sync overtime, so having a means of leveling them automatically is pretty handy.

RAM

@Phaedrux yep that's what I meant, I will see if I can do it once I get the hotend installed and recalibrate/ tuned.

RAM

@Phaedrux just want to make sure I am understanding this right before I actually do this.

My build plates 310 x 320 mm in size, I have 2 leadscrews and the machine printable height is roughly 480mm

;example for 2 leadscrews for config.g
M584 X0 Y1 Z2:4 E3; two Z motors connected to driver outputs Z and E1
M671 X-20:220 Y0:0 S0.5 ; leadscrews at left (connected to Z) and right (connected to E1) of X axis
M208 X-5:205 Y0:200 ; X carriage moves from -5 to 205, Y bed goes from 0 to 200

So looking at this I take it I remove one of the stepper motors from the ZB socket and connect it to E1 motor socket.

Then make the config look like this so it fits my machine.

M584 X0 Y1 Z2:4 E3; two Z motors connected to driver outputs Z and E1
M671 X-20:320 Y0:0 S0.5 ; 320 would be changed to the actual distance of the other z screw from the 0 z screw
M208 X-5:320 Y0:330 ; X carriage moves from -5 to 320, Y bed goes from 0 to 330

Am I thinking right or totally wrong ?

You have to move a specific motor. Because of the order you have defined the motors, Z2:4, and the order you have defined the leadscrews (left at X-20 Y0, then right at X320 Y0), you need to:
Plug the motor that's turning the left leadscrew at X-20 Y0 into Z
Plug the motor that's turning the right leadscrew at X320 Y0 needs to be plugged into E1

Also, don't forget to put the jumpers back on the second set of Z motor pins.

@droftarts thanks for the information on how to do that I will have a go at it once I get everything working as it should.

Think I might have messed something up along the way.

I did a print last night with a word on it and it came out back to front so do I have the motors in the wrong ports or could I have something else messed up.

Please excuse the poor art work but I thought it might be best to show how my machine is to try and make things clearer.

as you can see my machine homes to the left on the X and to the rear on the Y.

I tried to look this up but DC tends to explain things in a way that I don't always understand. Please don't get me wrong the guy is a wizard but I miss the way he explains some of the things sometimes.

From what I read and if I understand this right is my machine meant to be homing to the left for the X axis and to the front for the Y axis ? and if I input say +15 Y on the DWC then it is meant to move to the rear and not to the front like it is currently and +15 on the X will make it move to the right as it currently is ?

hevo directions.png

the way the motors are marked in the picture is how they are plugged into the Duet 2 wifi

If my corexy machine is meant to home the X to the left as it is and the Y to the front then could you please tell me what I need to change as I am really confused at the moment with what it is doing.

The direction it homes in will depend on where the endstops are. But the direction of movement positive or negative should be such that -X is to the left, and -Y to the front. That makes the front left corner 0,0. A right hand cartesian coordinate system.

And as applied to the printer
dbot axis.png

Back at the start of the thread it was suggested to swap the motor cables, did you do that? I'm thinking that may not have been necessary and we only needed to change a motor direction.

In the corexy setup page there are some motor tests. If you run them and report the results we should be able to know what needs to be changed.

https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Testing_motor_movement

RAM

@Phaedrux Yes you are right I did what was suggested and switched the motor cables on the duet but they are as the previous picture displayed as I double checked when I was doing the picture.

I have run the motor tests and this is what it is doing now.

Just so you know this is the type of explaination that I can't get my head round as I can't find a diagram of what is what.

"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."

Also here is my config.g if it helps.

Ok, so based on the results of your G91 G1 S2 X10 F3000 test you're moving in X+ and Y-, so...

If it moves towards +X and -Y, or towards -X and +Y, turn the power off and swap the X and Y motor connections.

Swap your motor connections and re-run the tests.

RAM

@Phaedrux now it is moving the opposite way to it was before with the motor cables swapped.

G1 S2 X10 F3000

If the head moves diagonally in the +X and +Y directions, all is well.

Ok, so all good there.

G1 S2 Y10 F3000

If the head moves diagonally in the +X and -Y directions, all is well.

All good there too.

Looking at your endstop configuration...
You have M574 X1 Y1 S1 which puts both endstops at the low end of travel. But you actually have the Y endstop at the back, which is the high end of travel.

So you should have M574 X1 Y2 S1.

Now for your homeall you should have...

With this you should be homing in the right direction and printed parts should no longer be mirrored.

I changed the homeall.g file and now it is doing something strange when I press the homeall in DWC.

it homes the X fine but then goes back to the Y and seems to slip then starts to move to the right and keeps going.

just incase there is something messing around causing a conflict.

on a side thought if I leave my homeall.g as it was it homes as it would normally (front left corner) if I was to move the endstop there would it cause any issues and would the prints be not mirrored or any other strange things?

if it is easier to move the endstop for the Y I can do that easy.

I forgot to mention before when I changed the homeall to make the Y move to the + direction, that would also need to happen in the home Y.

Front left? But your picture before shows the Y endstop at the back. Perhaps a photo/video of your actual printer?

RAM

@Phaedrux if I only change the 1st part

M574 X1 Y2 S1

But don't change the homeall.g file that is when it homes to the front left corner.

If I also change the homeall.g and do the M574 X1 Y2 S1 that is when it homes to the rear as it was before but then seems to go to the Y endstop slips and then travels to the right.

What I was trying to ask without confusing the issue was if I leave the homeall.g file unchanged and just change the config.g line to M574 X1 Y2 S1 as suggested and then move my optical Y endstop to the front of the machine so it is where it should have been in the 1st place would it be able to print things not mirrored / back to front etc or do I have to change the homeall.g file.

I was only asking to see if there was a easier solution to the problem when the homeall.g file got changed and it causing the issue where it seems to hit the Y endstop and then slips and travels right.

I will try and get a video of it doing the problem in a bit.

EDIT
couldn't upload the video here so here is the videos on youtube

This is with just the M574 X1 Y2 S1 done in the config.g and not changing the homeall.g file.
M574 X1 Y2 S1 Only

This is with both the config.g file edited with M574 X1 Y2 S1 and also the homeall.g file edited with the changes as suggested which causes it to bounce on the Y endstop and then move off to the right.
Config.g & homeall.g files edited

I'm getting a headache, how bout you? We'll get there.

if I leave the homeall.g file unchanged and just change the config.g line to M574 X1 Y2 S1 as suggested and then move my optical Y endstop to the front of the machine so it is where it should have been in the 1st place would it be able to print things not mirrored / back to front etc or do I have to change the homeall.g file.

No. Because your original homeall has Y moving negative/low end, but M574 Y2 means the endstop is at the high end. So if you just moved the endstop you'd still end up with mirrored parts. The physical position of the endstop is irrelevance since we just have to tell the firmware where it is.

In your video where it hits the endstop and then continues to ride against the frame it looks like that's the point where it should be moving the center of the bed, but it thinks it's at the low end and that the bed is actually beyond the rail.

So let's take it from the top just to cross our Ts and dot our Is.

Please post your config.g, homing files as they are right now.

Then answer these tests.

With the power off, physically move the print head to the center of the bed. Power on and send G92 X150 Y150 Z5. This will tell the firmware to think that the Axis are homed and the position is close to the center of the bed.

Then use the jog buttons in the DWC.

Does X- move left and X+ move right?

Does Y- move to the front and Y+ to the back?

Also redo the G1 S2 X10 and G1 S2 Y10 tests as before.

Hopefully with all that information we can pin point what needs to be changed.

RAM

@Phaedrux yep I certainly am getting a headache and yet I have no clue what I am doing

TESTS

X -10 moves left
X +10 moves right

Y -10 moves to the front
Y +10 moves to the rear

G1 S2 X10 moves forwards and to the left
G1 S2 Y10 moves forwards and to the right

If there is anything else that you need let me know and I will upload my firmware to dropbox, or if you need to talk through this to make it easier then I can do that too. Basically whatever you need just let me know and thanks again for all the help.

Phaedrux

I'll take a closer look later today.

RAM

@Phaedrux thank you very much

Phaedrux

Ok a couple more questions.

Which motor is plugged into which driver? I know we did some swapping, but how are they connected right now?

We're gonna try and make your configuration match my own, so here's what I have.

The left motor is connected to the X driver, the right motor is connected to the Y driver.

Then in the drives section for motor direction I have the opposite of you.

you have:

; Drives
M569 P0 S1
M569 P1 S1

I have:

; Drives
M569 P0 S0
M569 P1 S0

So make those changes to the motor wiring and the direction of rotation, and then do those motor tests again.

Also, when you say

G1 S2 X10 moves forwards and to the left
G1 S2 Y10 moves forwards and to the right

Does forwards mean towards the front of the printer or towards the back of the printer?

G1 H2 Z-5 F6000 ; lower Z again
G90 ; absolute positioning

Once we have the directions sorted out the homeY will also need to change from that to this:

G1 H2 Z-5 F6000   ; lower Z again
G90               ; absolute positioning

And your homez should use the same X Y position to probe the bed as used in home all. Right now you have

G90               ; absolute positioning
G1 X-18 Y15 F6000 ; go to first probe point
G30               ; home Z by probing the bed

Except in your homeall right now it doesn't make a lot of sense.

G90
G1 X150 
G1 Y146 Y130 F6000      ; go to first bed probe point and home Z
G30

The first one moves to just an X position, and the second line has two Y values. So I'm guessing it should be G1 X150 Y130 F6000 instead

RAM

@Phaedrux
Left motor is plugged into the X axis
Right motor is plugged into the Y axis

My motors are at the front of my machine

G1 S2 X10 moves to the rear right corner
G1 S2 Y10 moves to the front right corner (diagonally towards the front where the Y axis motor is)

X -10 moves right
X +10 moves left

Y -10 moves to the rear
Y +10 moves to the front
If I now try and home X & Y indiviually they move away from the endstops.
(If looking at the machine from the front the Y enstop is at the rear left and the X is on the left)

Also changed the home files as instructed to.
