My prints are in mirror, but the axis are good.

Hi Everyone,

i am new to Duet 3D but what a amazing board, i finetune everything now.

But i have some strange problems.

my printer prints in mirror.
I have a Tevo Tarantula but when i print a
a calibration cube come out like this

My bed is 200 mm -->
and 280 depth

        ______ x _______   
       |                         | 
       |                         | 
       |           Z            Y            <------- the letter z is also in mirror
       |                         | 
       |                         | 
        ---------------------

but when i move my axis everything is correct.

my x axis homed on the left
my y axis (bed) home to the back of the printer

my + is to the right en - to the left

the stl is make in simplyfi 3d and is a good file, i printed many times on my mks board.
maybe someone have a idea?
i will make some pictures and post it

many thanks

Can you post your config file?

Off course

You have set up your machine with a left hand coordinate system, when it needs to be right hand. When you jog the Y axis, which way does it move? If +X is to the right, then +Y should be to the rear.

mickey30m

x+ is x axes to the right
y+ is y axes to the rear

Are you sure that you don't have mirroring enabled in S3D?

dc42

That is quite good for low cost delta printer mechanics, and you should be able to get reasonable prints from it. But I think you have some sticking in the mechanism. Check that the motor current is set to at least 60% of the rated current of the motors, and consider lubricating the joints (I use silicone grease for that).

@dc42 i am sure off that

mickey30m

@dc42 the motors are 1,7 a. and run on 0.8 i believe.

some config with mks board, everything was working good...

On my computer, S3D defaults to a left-hand axis system - which is completely wrong - unless I check the Y box next to "Flip build table axis" in the G-Code tab. See https://msdn.microsoft.com/dynimg/IC155562.gif and check that both your printer and S3D are using a right hand coordinate system.

mickey30m

strange,

okay i change in s3d flip y axis see picture, but now the screen is mirrored in S3d

i going to print a cube and lett you know...

mickey30m

now he prints exactly like the screen in S3D .. But it is also in mirror

how can i see if my printer is left hand orientated. ??

or what can i do

mickey30m

@dc42 it is a Tevo Tarantula, with a lot of improvements.
thats why i want the duet on it...

he can print very nice...

this are prints from a couple of months ago

the blue one is flex material

Looking from in front of the printer, if +X moves the print head towards the right and +Y moves the print head towards the rear (or moves the bed towards the front, if the printer has a moving bed) then it is right handed.

mickey30m

okay than its right handed

but my prints are still in mirror

Which way do the axes point in S3D's representation of the bed?

x+ is x axes to the right
y+ is y axes to the rear

Are you saying that pressing Y+ is moving the bed towards the back of the printer?

Can you post the first 20 or so lines of the gcode program you are trying to run?

Does the program call out X- moves when they should be X+ moves?

Or post the model somewhere and someone can try slicing it for you and send you the gcode file to try running. To see if you still have a mirror issue then. That would help rule out the printer firmware.
