Reprap Fisher XT Upgrade

thingiverse

Decided to increase my build height to 345mm when I replaced the acrylic panels; modified panel design uses standard 800mm rods and increased placements for ends, tops, and cables so cabling can be equally distributed up all three sides. This requires small notches made on the plate under the print bed to allow cable to pass. Upgrades I recommend and have done to my machine are carbon fibre arms, glass bed - currently using 2mm double sided tape on original build plate, and fan modified to come on only when hot end is above 35c (thanks to DC42's latest 1.09o-dc42 firmware). I should add that XT stands for extra tall. Print Settings Printer: Laser Cutter Notes: Laser cut from 3 mm aluminium. Post-Printing Installation I recommend acid etch primer and a few coats of finish before installation. Original rods are replaced with 800mm rods; belts need to be replaced with longer ones, both readily available on eBay. Bowden tube also needs to be replaced; when installing trim this down to be as short as possible. Leave the lid off to make room for homing. A couple of home switch leads need to be lengthened; I recommend soldering these joints and connection to micro switches. Stepper motor for extruder also needs to be a couple of inches longer; get longer cables from e-makershop or cut ends and solder in some extensions.
