G1 Y-15 F6000 ; go back a few mm for clearance this is there because if I don't have it then it clips the Y endstop as it moves out to do the Z probe in the centre of the bed.

I don't know why the steps would be out as I haven't changed them at all. I will see if I can find the original config.g file and compare them to the latest config.g

@Phaedrux I have measured the X & Y and they are both at 10mm when asked to do 10mm movements (I checked a couple of times) if the steps are correct then whatelse could it possibly be ?

in my homeall.g file it tells it to home and then probe the bed at X 146.0, Y130.0 which is what it was before. I got the center of the bed again and now it is X 146.0, Y 190.0 which I changed in the homeall.g file and it seems to be working as it should again when using the home all.

I have no idea as to why it has changed but something is still not right.
It will home to the center of the bed but as soon as you try and do a print it is way off on the Y axis as it starts to do the print like it was before I did the new settings in the homeall.g I have a printable area of Y270mm, X280mm even though the bed is 310 x 320.

What I can't understand is that before when it was printing the dimensions right just mirrored. now that it is moving in the right directions it seems to have thrown all the dimensions out ?

I set off a test print to almost the full dimensions of the bed and you can see how far off the Y axis is when it tries to print, it is about 40mm out

EDIT**
I have moved the Y endstop to the front and switched back to my old homeall.g & homey.g files and they seem to be homing in the right places. I am going to try and do a test cube to see what happens.

EDIT
still printing to far forwards on the bed for some reason. would I be better off just redoing the whole of the RRF configuration tool again from the start ?

as you can see from my Z axis leadscrews the cube is printing about 20-30 mm to far forwards and when it starts the print and does the nozzel wipe the nozzel is off the bed to start with

We can account for that difference in the M208 commands to define the size of the bed. Here's how.

Jog the nozzle so that it's at the front left corner of the printable area.

Send G92 X0 Y0 to tell the firmware that this is what we can to consider the origin point of the printable area.

Now jog the head to the left until the endstop just triggers. The X position will be a somewhat negative value because it's to the left of our 0,0 origin. Use that negative value for the M208 X minima.

Now do the same for the X+ side and jog the nozzle all the way to the right so that it's just on the edge of the printable area, or as far as the travel will allow it to go. Now use that X position as the M208 X maxima.

Then do the same for Y min and max.

Then in your slicer you may have to update the maximum bed size.

G92 X0 Y0

I did that part but for some reason I can't go into negative moves now am I meant to send a command so that it will allow movement past - ?

I did try sending M564 H0 but it didn't work.

Thanks for all the help with this I wouldn't have gotten this to work, it would have ended up as scrap metal and a hammer through the duet.

Phaedrux

@RAM Ah yes. M564 S0 will allow you to move past the boundary

thanks i knew there would be something I just didn't know what on earth to search for

I use simplify3D I have put the bed size in so that it matches but would I need to change the values for the Global G-code offsets & Toolhead offsets too do you think ?

Phaedrux

@RAM I'm not a simplify3d user, so I'm not sure what those offsets are doing.

Thanks guys for all the help with the issues, once I have finished totally building I I will post it in the built area.

Did the upload issue get resolved?

Nope I have given up with that side of it I will just keep pulling the SD Card for now so I can get the thing dialed in I am having teething problems with this bowden setup and I am used to direct drive so a whole new ball game for me.
