| == YRS Build Log NEWEST AT TOP ==
| |
| | |
| Rebuilt extruder and sourced new hobbed bolt to feed more accurately. Also changed most M3 nuts for nylon locknuts to prevent them from shaking loose.
| |
| | |
| Fitted custom couplers to give greater accuracy and more reliability for Z movements.
| |
| | |
| Finer Mark IV print head sourced from UK supplier.
| |
| | |
| New hotend donated by Richard Crumley. The mark IV is PLA friendly, unlike the now defunct mark 1 supplied. It is hoped the Mark 1 can be recommissioned with a choice of hot ends for ABS and possibl TPS (NinjaFlex rubber) to give more choice of build materials.
| |
| | |
| Rehoused electronics in a wooden box to give greater protection from tea splashes or similar.
| |
| | |
| Trimmed pots for current limiting by hand testing with Pronterface so 0.1, 1, and 10 mil steps all work. X lowered to about 25% of a turn, Y by only 10% of a turn, Z by about 15%.
| |
| | |
| Trimmed a fan and enclosure to fit over the board for further testing regards overheating issue.
| |
| | |
| Initial Calibration all done.
| |
| First parts printed !!, 2 * Calibration 'L' Parts
| |
| | |
| Steppers start to miss steps after about 5 mins of printing
| |
| and the stepper driver chips get hot (too hot to touch)
| |
| So need to either reduce stepper current or fit a fan for the electronics board.
| |
| | |
| The steppers are functioning with what seems like quite a lot of reserve power when first stated (drivers cold) so I suspect that reducing the driver current will work to keep the temps down and still give enough drive power. | |
| | |
| This is just tweaking the pots on the stepper driver boards down a bit.
| |
| See [http://reprap.org/wiki/Pololu_stepper_driver_board Here]
| |
| for more info. | |
| | |
| Simplest way is probably to create a test gcode file
| |
| that move one axis at a time zigzag at full speed e.g.
| |
| | |
| G1 X100 F6000
| |
| <br>G1 X50 F6000
| |
| <br>G1 X100 F6000 <br>G1 X50 F6000
| |
| <br>
| |
| ...
| |
|
| |
| and turn the drive current down till it starts to miss steps then back up a bit.

| |
| | |
| Wireing sorted and tie wrapped.
| |
| Electronics board fitted.
| |
| Hot Bet fitted and ready for leveling
| |
| All limit switched fitted and wired.
| |
| | |
| Hot end needs fitting, follwerd by PSU connection and plug in of electronicd to the RAMS board then
| |
| Unit ready for power on and initial testing.
| |
| Chris 27 Dec
| |
| | |
| | |
| Box of remaining parts tidied.
| |
| All non YRS 3d Parts (i.e. hackspace reprap parts) moved to shelf to
| |
| try and help with keeping things in order.
| |
| Only major bits left for fitting are hotbed, hot end and the electronics.
| |

| |
| | |
| | |
| Extruder built 26/dec chris
| |
|
| |
| X carriage movement a bit stiff, a couple of tries using washers/spacers to make it run better
| |
| it now moves reasonably, further adjustment may be needed once the electronics/motors are connected and under power testing can be done.
| |
| | |
| X assembly built and fitted
| |
| | |
| | |
| X Smooth rods too long (length for non LM8 X ends)
| |
| Cut down by 15mm to 435mm
| |
| | |
| Z motors added with coupling rods - motors not screwed in place
| |
| notes on web seem to indicate that it may be better to not screw these down but
| |
| to use tie wraps to hold them in place and redude out of alignment rough spots/vibration.
| |
| | |
| X-end idler was broken
| |
| New part printed
| |
| | |
| == Next steps ==
| |
| | |
| == Fit SD Card Reader ==
| |
| | |
| The part has been sourced, but the electronics board in the YRS printer will need some pins added to enable connection. Also, the firmware will need updating to use it. Fitting this part will enable the printer to work independently of a laptop or other controlling PC.
| |
| | |
| == Fit Display ==
| |
| | |
| A display has been donated (actually part of 5 suitable for Arduino projects). Fitting a display will let the temperatures and positions of the head to be displayed, letting people know how hot the printer is operating at without burning their fingers or using a laptop.
| |
|
| |
| === Build Extruder ===
| |
| | |
| Completed.
| |
| Extruder all built and placed on x carriage, not screwed down yet
| |
| as need to check hot end fit/alignment etc.
| |
| | |
| === Build Hot end ===
| |
| | |
| All Done. Opon examination of the hot end bag it turned out that the hot end came pre-built
| |
| all looks in good shape, ready for mounting.
| |
| Not mounted yet as it is a bit fragile and probaly needs to be done after alignment/coarse testing of movement.
| |
| | |
| === Fit Extruder/hot end ===
| |
| | |
| === Build bed (heated plate etc) ===
| |
| | |
| Completed, Bet built and fitted, needs alignment
| |
| | |
| === Electonics ===
| |
| | |
| All checked (as in stock checked :-) ) and complete
| |
| this is probably next step now to allow some motion testing
| |
| the X - axis is still stiff/catching and may need some more work
| |
| unless it frees up under power.
| |
| | |
| === Wire up ===
| |
| Almost complete
| |
| All wires connected. Ramps and Arduino fitted to board, needs PSU wired up and motors et al plugged in.
| |
| | |
| Needs a USB 'B' cable to allow comms/prog of Arduino.
| |
| | |
| === Functional testing and coarse alignment ===
| |
| Complete
| |
| | |
| === Commissioning ===
| |
| | |
| Complete.
| |
| === Calibration / fine alignment ===
| |
| | |
| Complete

YRS 3D Printer Status and Log
The YRS 3d printer has been rebuilt and recalibrated and is currently available for inductions and printing to Hackspace members. The print accuracy is to within +/- 0.04mm in X and Y.
The easiest way to get inducted is to put a request on the googlegroup mailing list. Inductions are run for "donations" - what it is worth to the member. Some members are already very familiar with 3D printers, others are not. Donations of PLA or ABS filament in 3mm diameter are also very welcome Members can purchase their own printing supplies - one of the most reputable sources is Faberdashery, the link is at the bottom of the page. PLA is the most environmentally friendly and is a bio-plastic made from sugar.
The YRS 3d Printer is being 'lent'/allowed to be completed by the owners
the ail is to complete this and then finish the Hackspace owned printer
to have a '3d Printer as a tool' available in the space.
The YRS printer is basically complete and can now be used "Standalone". The next development stages are for it to print in ABS and other materials, to have a quick change option for changing materials, and to have a Flex3drive mechanism added to improve maximum printing speed.
