Mirrored X axis

Grace Dert

Hello I have been printing for a long time and have recently bought a FT5, which I am not thrilled with but oh well. I have recently upgraded the board with the duet 3D wifi and I love it! However my axis in the x axis is still flipped! I had to move my axis end-stop (because it was in the wrong stop) so now it should be homing at the back right. However my x goes in the opposite direction. Please help!

the homing moves are defined in the home[xyzall].g files. if you want to change the direction. you will need to edit them.

Use a M569 command in config.g to reverse the X axis direction. See the GCodes page on the wiki.

Hello again, I tried this however when I press home all it still does the same thing. I then changed the home all file and it seemed to work. But when I tried to print something the motors drove in the opposite direction for the x/y and then only the y moved but only a little. So it was 'printing" in the back corner. I am not sure what is going on. I tired recreating the configuration settings and now nothing is moving. Really confused... what should my next step be?

Grace Dert

Okay I tried uploading new config.g file and now I can't eve connect to the board...

Can you post your config files and homing files?

There have been a few other posts about the FT5 such as this one. The confusion arises from the fact it uses the back right as the 0,0 point rather than the front left.

Currently my x and y home but go to 300 after hitting end stops and my z does not move at all. Sorry for the late response. Thanks for all the help so far!

We're gonna need to see all the homing files.

In general, here's what you need to do to define your coordinate system. The FT5 is a little tricky because by default it puts the origin at the rear right, and has some printed grid on the bed surface (I think?) but really it's all arbitrary.

First, choose a FRONT for the printer so that when you're looking at it standing in front of it 0,0 is the front left corner, X+ goes to the right, Y+ goes to the back. This does not change because it's describing the physical layout of the printer.

Next, Measure the axis length for X and Y and enter that in your M208 command to set the axis limits. 0 at the low end (or even negative if the head leaves the bed surface to hit the endstop). This does not change because it's describing the physical layout of the printer.

Now identify where your endstops are located. They can be at the low or high end of the axis. Define them with M574. M574 X1 Y1 for low side, M574 X2 Y2 for high side, or any combo thereof. This does not change because it's describing the physical layout of the printer.

Now setup your homing movements. If the endstop is at the low end of the axis, the homing move must be negative. And vice versa. This does not change because it's describing the physical layout of the printer.

Now test the motor movement direction. using this page: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Testing_motor_movement

If X+ moves to the right, you're good to go. If it moves left, you need to change the motor rotation for the X driver by changing the M569 S0/S1 command in config.g. Same goes for Y+ moving to the back. If you've connected the motors to their default drivers, it should be mapped like this:

M569 P0 S0                                         	; Drive 0 (x) goes backwards
M569 P1 S0                                         	; Drive 1 (y) goes backwards
M569 P2 S0                                         	; Drive 2 (z) goes backwards
M569 P3 S0                                         	; Drive 3 (e) goes backwards

If you follow those steps your printed parts will match the orientation in the slicer and won't be mirrored.

I think what has happened is that you moved the endstop but didn't change the M574 command to match.

So I currently got my x and y homing but I just want to check and see if I did it right if you don't mind. However my z axis is not moving at all which is odd...

So I think I fixed everything! Maybe... everything homes now and so far doesn't appear mirrored. Thanks so much for the help so far!

Are you using an endstop or a z probe to home the Z axis?

Grace Dert

@Phaedrux endstop

M574 X2 Y2 Z0 S0 ; Define active high microswitches

In that case you should change that Z0 to Z1 (assuming it's a zmin endstop). Z0 means no endstop configured.
