Description

This is the top mounted system based on my other rail system that can be found here

AMS Lite Rail Top Mount.

This rail system allows you to pull the ams lite out on a track to be able to swap filament rolls a lot easier and then tuck away again before printing.

Printing

All parts should be printed in petg, i printed with a .6mm nozzle for additional strength.

• Knurled nut test is useful for insuring that a knurled nut will fit the ams holder before printing
• The AMS Holder is printed upright to provide better strength / resistant to splitting on the layer lines, be careful with this part as it is tall and bed slingers are not as good with tall thinner items, brim is essential but I also recommend using 3dlac on your bed, slowing down the print speed and printing this part independant of the others will also help.
• The rails I recommend printing upright for additional strength, however this creates a lot of noise when sliding the ams back and forth so I personally opted to print them flat
• braces are optional additional safety measures to provide more contact with the rail in case something does split

Installation

• AMS Holder will mount where the original holder was but before screwing onto the ams lite you can use the holder as a guide to screw the rails onto a surface. (make sure to leave enough clearance between the wall and endstop for the filament rolls). As an additional safety measure I have made holes for all 4 screw holes on the ams lite.

• When installing the rails I used the ams holder as a guide to align the rails, fixed them to the surface using vhb tape and then screwed in place, there are additional holes for mounting the rails to provide extra support, depending on where you are mounting these you may wish to use m3 bolts instead.

• If you find the rails a bit to tight use a knife or deburring tool to take a bit of the plastic off, I also recommend using some candle wax(dry) to lubricate the rails up, this will reduce friction and create a nicer sliding motion.
• Depending on where you mount this you may need to extend the ams lite connection cable, I haven't needed to do this, there is plenty of information on line if you need to.

• I have included additional braces for the ams holder, this enables better contact and additional support for the holder, you will need m4 knurled nuts, short m4 bolts and a soldering iron for this optional part.

The center hole in the brace is for an optional steel safety wire you can loop through the whole system.

I have included a lot of additional safety features which are probably over the top but depending on your setup you may find these helpful, it's also worth noting that you may need to print some additional ptfe organisers to keep tubes from catching but this will depending on your setup.
