Instead of changing firmware or changing the wiring, I flipped the motor direction. See the first photo below. Motor shaft was on the right side, now, the motor shaft is on left side, so the the bed moves backwards. I moved the Y endstop to back and now it prints fine. only the problem is In Pronterface, if I press -Y -- bed moves backward (towards the Y ...

For most Cartesian printers, the homing position is at the front-left corner of the build plate. End-stop switches can be at either end of each axis (and even both), but the firmware must be configured accordingly. A common arrangement is to have end-stop switches at X-min, Y-min and Z-min positions. You will see this on pretty much all budget printers, but ...

There is a way that you'd be able to do it but its not really conventional and could use up some filament: Calculate out where you want it to stop. Then, when you want to change colors, you set your slicer to print a floating object in the air that isn't part of your print to purge out the old filament and prime the new one. That way, when it goes back to ...

When calling for a manual color change, Marlin is set up to allow to extrude extra filament. This is to ensure that the new filament is in the hotend, but it also allows to "purge" the old color from the hotend by extruding till no mixed color comes out anymore.

Anyone know any filaments or methods to have an immediate color change There is a solution (or multiple) where you can have multi color filament without a gradual transition from one to the other color (seen from the filament side, not the extrusion/nozzle side), i.e. immediate color change. This requires an additional piece of equipment to do this ...

It takes at least a few cm of extrusion to purge the old color before switching to a new one due to mixing in the melt zone, and possibly much more depending on the particular pigments. If the old color is something bright like red and the new one is white or something close, it can even take many tens of cm before you get a clean new color. Multi-color ...
