Printing in the middle of the bed
-
The Duet will print where the Gcode generated by the slicer tells it to. You need to configure the bed size of your printer into your slicer. At the Duet end, check that the X=0 Y=0 point is at the corner of the bed, and if necessary adjust the parameters in your M208 S1 command so that it is.

ok so far i am slowly making progress
minima is set
x60
y-5
z0
maxima is set to
x280
y215
z210this is where the progress of the homing is:
told my printer that once the endstops have been reached, that is where the 0 of that axis is. -
The issue i'm having is, adjusting the gap between the x axis stepper motor holder and where the bed actually starts,
The only thing i could think of at the moment is by physically moving the end stop closer to where the bed starts.
I.e.

is that why you have x 60 as a minimum? if so, you will have to do some math to compensate for size of bed vs offset. make a few guestimates or manually place ph in middle of bed and get x,y coordinates you want then after home y, move to that and home z (all do able via g code). plug the dimensions into your slicer for bed size and you should be good to go IMHO, 60 mm is a lot to give up on print volume so am wondering if sensor is that far from edge of bed or if you are cutting off part of usable area? DISCLAIMER, i am a bit of a newbie myself so our betters on here will correct me if i am terribly wrong LOL

Here are a couple of diagrams:
Exhibit A(Original Setup)
Exhibit B(Potential Setup )
Exhibit B would be physically moving the end stop

i am by no means sure on this but as i understand it, that should not be a problem, just need to dial in offsets for bed geometry. might try moving bed to 4 corners and seeing what the reported position is then base your settings off that. IE 300x300 bed but 400 mm movement on x you may also need to lie to your slicer to get dead on center of bed lol what are you using for that btw?
-
Alternatively you can tell your printer that the minimum is -60, then "0" will be at the logical point you want to print at.

Thnks
So should the minima and maxima go from this:
minima is set
x60
y-5
z0
maxima is set to
x280
y215
z0to this:
minima
x-60
y-5
z0
maxima
x220
y220
z0
Would this allow the x0/y0 to be on one of the corners? and get the printer to print in the center.@ FrankNPrinter
I use Cura/Repetier host since these are free and available on linux, I really like Cura, since the settings seem clear.
I've seen somewhere that in the repetier host that i could set the offset of the bed there
I wouldn't mind a slicer that allows me to tell the print where not to print the brim, skirt, raft i.e. 'don't print bed adhesion in screw holes' -
If anyone ask, I have managed to print successfully, until i decided to take it apart for a potential non-printed upgrade,
-
I managed to get the X axis stopping where necessary, so i'd like to mark this thread as SOLVED
This was achieved by printing out a endstop holder for these mechanical switches, so now i have a good enough set up get the homing and placement of the print where actually want it.
Thanks Prusa's, Delta's and CoreXYs
