I just printed the reprap badge from thingiverse. Pretty sweet and a good quality print except the print seems to be mirrored. As in the reprap text was backwards.
Skeinforge created a tool path that was correct but I just don't get it. Photo is attached. Any help would be appreciated.
Thanks again

I'd say you have your x axis the wrong way around, meaning when you tell it to go in the positive direction it goes in the negative. To fix it you need to invert the x direction in the firmware, and move the endstop to the other correct end of the axis.
Nice print though

I was thinking that too, being that my x axis was traveling in the wrong direction, but when I tell it to travel positive, it does travel to the right. I'm going to dive into the firmware settings and see if it was something I accidentally tweaked when I was calibrating.
My machine is a Prusa Mendel, with Ramps 1.2 and the Sprinter firmware. It wasn't a kit though, I scrounged parts over a few months my last year of undergrad.
More on the matter later.

If +ve X moves the head to the right then that is correct. +ve Y should move the bed to the front. Perhaps your y axis is reversed.

Yep definitely had a "duh" moment. It wasn't the x axis that was flipped, it was in fact the y axis. Now I don't have to read stuff with a mirror.
I'm attaching the stl file for the "crest". Also if you check out Makerbot castle on thingiverse, there's some other pretty sweet objects related to this.
Thanks again

Nice I printed one but it's nowhere near as nice as your will put up a picture tomorrow.
Here is my first attempt, notice the surface dragging under the writing, I don't know what is causing that yet and I need to change my retract settings I think so that the centers of the letters get printed properly.
Don't look at the infill overlap I know that is wrong and it's my fault I changed the setting and forgot to change it back but at least I know what that one is.
If anyone has any suggestions on how to improve this print using SF41 and Gen6 I'm listening

I think Im having the same problem.
I had to draw something backwards in order for it to be printed correctly, see my post: [omemon.wordpress.com]
But if I change the y axis motor wiring, wont that change the direction of the "home" Right now home is correctly bringing the base back home... so then what should I do?
Thanks

Greg Frost: My home is currently located Left back. So I guess I need to put the optoend on the back of the machine, no the front.
Front is where the Y motor is located and thats where the Huxley instructions told me to install the y optoend.
Thanks for the advice. I'll move the y opto end.

The limits are normally at the same end of the axis as the motor with the y motor at the back and the x motor on the left.
If the y motor is at the front then the x-motor needs to be on the right. I.e. the whole machine is rotated 180 rather than one axis flipped on its own, as that causes mirrored objects. Swapping X and Y also mirrors objects.

oswim8, You can just move one of the optos to the other end of the carriage, without moving the motor, and then adjust the wiring so that moving in the - direction moves toward the opto.
Or, you can bodge it, and just swap the x and y axis around (y on the extruder carriage, and x on the build platform).

It doesnt matter which side the motor is on, it is where you put your endstops that matters.

True, but on the Sells Mendel the Y limit switch is attached to the Y motor bracket and the X wiring comes down a filament attached to the X motor bracket so the limit switch needs to at that end as well. The Prusa is more flexible, but the wiring will be messy if it goes to the other end of the axis.

I am having the same problem with mirroring, although i cant figure out which axis needs to be changed? I have attached a photo, the hole on the left in the photo is actually ment to be on the right?
does anyone know if this is the x axis or the y? and if so how do i change this?
