| + | > If you have a Duo you might consider the following idea rather than "centering" your Y-axis (you still want it perpendicular however): With two extruders it is useful to be able purge both hot-ends without having to move the X-axis to each side of the print bed. Unfortunately this is not possible when the Y-axis is positioned in the center of the frame (another 10mm in frame width would have been very useful for the Duo). Instead, to accomplish this you need to: | ||
| + | > * position the X axis end-stop all the way to the left of the frame so that the end-stop switch clicks when the X-carriage is around 2-3mm from the frame edge (don't worry the end-stop switch is only used when homing and the X-carriage doesn't approach the stop at high speed; in all other circumstances the controller ensures that the motor is never moved to less than 0 position) | ||
| + | > * then position the Y axis so that the nozzle of the right-hand extrude just clears the edge of the Helios heated bed indent (i.e., imagine X represents the nozzle and the line is the edge of the hot bed %%/----\_X___/----\_____/----\%% ) | ||
| + | > This does mean you will lose 5mm off the right-side of your print area for your left extruder //unless// you position you glass slightly to the left of center on the hot bed - which is not a problem for PLA (and you'll get varying results if you try to print right to the edge of the heated bed glass with ABS anyway); however it does mean that you can easily work on both your extruders without having to move the X-carriage around. Remember to set you X-Max in Repetier-Host and Bed Center in Slic3r correctly to avoid hitting the right-hand side of the frame (i.e. set these to 5-6mm less then what they would otherwise be). | ||
| If you ever bang into the printer and jar it, check to make sure the Y axis is still square. Also check it every time you transport the printer, even if it's only across the room. This adjustment is the //only// thing keeping the Y axis perpendicular with the X axis. | If you ever bang into the printer and jar it, check to make sure the Y axis is still square.
