non AMS printers

There are some things to consider, when printing multicolor on the first layer.
If you have a printer which autolevels at the beginning of each print, you will run into problems if you leave the parts where the probe comes down.
It is important to move the parts away from the center in this case.

Then you would first print the numbers, "deactiveate" the dials, so they are not slicced.
If you use skirt loops around the print, make sure they are at least 2 cm away from the print. Otherwise, if you forget to remove the skirt, you will have it on your dial.

The better you clean the stringing and blobs now, the better your dials will be.

Now you change the filament to the color of your choice for the dials.
In the slicer "activate" the dials, "deactivate" all numbers, slice the dials and print them. This should now print the dials around the already printed numbers, which of course you left on the buildplate.
I would highly recommend to activate z-Hop for the first layer, to not collide with the already printed parts.

The same procedure applies to the top part with the A, B characters and the arrows.
Here you could also add another color change at a higher layer, so that the "windows", where you can see the numbers, are highlighted.

It would be interesting to see what colors you all come up with, please share your makes.
