P3Steel X_carriage

This is an essential guide on building and installing an X-carriage for the P3Steel printer, as well as other similar printers. The assembly process involves eight critical components: 1) The idler side 2) The motor side 3) The x-carriage 4) A mount for the E3D V6 hotend and inductive sensor 5) A mount for the E3D V6 hotend and inductive sensor (mounted on the Alu X carriage) 6) A mount for the RepRapPro hotend and inductive sensor 7) Fan mounts for the E3D hotend with and without 3mm nuts in place 8) Hall sensor mounting. All printed parts were made using a RepRapPro printer at an infill of 40%. ** Assembly Instructions ** Once all the components have been printed, proceed with the following steps: 1. Clean up the bearing hole in the idler part and enlarge the screw hole to 4mm. Mount a ZZ624 bearing on both sides and ensure smooth operation. 2. Place M3 nuts in each of the holes for the smooth rods. Hold them firmly using an end of a 7mm drill bit, then screw in an M3X20mm hex bolt from the outside side down the nut into the grove in the bottom of the hole. Repeat this on both the Motor and Idler mounts. These are necessary adjustments to ensure parts mount correctly on Z-smooth rods. 3. Use a 8mm drill bit to clean up any remaining holes. 4. Mount three linear bearings - two on the top rail, one on the lower rail - into their respective holes on the motor and idler sides of each component. 5. Screw down both motors using 2x 2-inch linear bearings (Remember, proper adjustment will involve removing unnecessary plastic chunks from all bearing hole.) and tightening them until they fit snugly. 6. Mount X-carriage to printer base. 7. Tighten 4 M3 screws in place of "straightness". Adjust belt alignment until parts run freely up and down z-rods. 8. On one side, push the M5 nut on the thread and insert into it's socket at other end mount spring. Tighten second nut to make tension tight (this part involves a fair amount effort). 9. Insert bearing blocks tightly. Run bearings over and test whether X axis works smoothly or otherwise move in. 10. Place your GT2 50 pulley system together in their slots inside carriage - may need some file fitting, please make sure belt slides nicely up one side, passes through idler block, passes to carriage block at end and lastly into motor mount block, now take that long pulley part down towards opposite motor base, cut excess. Slide in 7-inch long smooth bearings with two retaining screws. Mount the last pulley - after which run in 8 mm wide X3.18x16GT2.50mm idler and slide both back together for better assembly fit of GT2 25 system onto carriage (may involve slight file trimming). Pull belts to tight them in. Take apart X carriagre part then tighten belts and mount fan unit first - attach fan on last bit as it moves down a notch or too to center printer, make adjustments. 11. Install sensors to either side before moving onto fans and sensor system 13 Insert your hall sensors into this particular mounting (three legs plug wiring into this little part still inside your X-carriage with electrical wires.) Assemble them properly. By doing so, you will achieve a complete assembly of an axis. Please ensure any adjustments you make do not damage it during process
