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 thisMy 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 printermy + 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 itmany thanks

Can you post your config file?
-
-
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.
-
x+ is x axes to the right
y+ is y axes to the rear -
Why can i not place photos?
i put it between the ( ) but it dont work
then as link ;'-)

Are you sure that you don't have mirroring enabled in S3D?
-
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
-
@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.
-
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...
-
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
-
@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.
-
okay than its right handed
but my prints are still in mirror
https://photos.app.goo.gl/04YhgIgobaxp101N2 -
Which way do the axes point in S3D's representation of the bed?
-
-
@mickey30m said in My prints are in mirror, but the axis are good.:
x+ is x axes to the right
y+ is y axes to the rearAre 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.

@tjb1
i will post a movie when the printer is done with my print.i need to make a few adjustments to print very damn tastic
but the problem with mirror image is difficult to solve
than i want to make the z hop beter , firmware retract.
now i do it in the stl (gcode) -

from starman_32.gcodeSo by reading one of the first actual print moves (G1 X71.613 Y105.968 F9600) the print head should be going to the RIGHT 71.613mm and the print bed should move TOWARDS you 105.968.
If it isn't moving like this then the firmware is configured wrong.
-
@timcurtis67 IT is moving like this.
That's are the problem. But IT prints in mirror.I try already swap cables change config
Print another stl but i dont know anymore -
Does your printer home Y to the rear or to the front? In Your S3D screenshot it shows all axes homing to min, but is that correct? Your config.g
Can you post your homing files?
I suspect that you have an axes direction reversed and are correcting for it in the homing files.
I would go through your motor configuration and testing again with this as a reference.
https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Movement_sectionEnsure that each motor turns the way you want it to and homes in the direction you want it to. It may help if you identify which drive axis is assigned to each Drive Number in the config.
This is what you had posted in your config.g. Is that still accurate?
