  1. A short weekend update. After a lengthy interlude while Windows 11 occupied my laptop I carried out one more calibration test print; the Polypearl tower. It looked like it might be a test too far but I was excited to see a decent model print out. I plan to keep the sliced files for these test pieces. My thinking is that given the inputs in the files a decent print should result unless something else has changes such as extrusion rate, filament quality a new and exciting problem with the machine. So lulled into a doubtless false sense of confidence I have sliced new files for the Flower using the same settings to repeat the 4 inch gun parts and the 2 pounder and we shall see how they come out. Thanks for looking in alan
  2. Hi Kevin Yes the number of variables in FDM printing is boggling - and a little depressing when you are trying to address a problem. Online opinions also differ on solutions which isn't always helpful. I'm glad to have got to an acceptable print by modifying the printer in much the same way you have, drying the filament and adjusting the speed and temperature along with trying to maintain a solid bed alignment. I would rather not get into retraction distance, refraction speed and all the other options in Cura. We are moving into the warmer weather here in South Florida so the air conditioning is running and the humidity in the house is much lower than in winter so its a good season for maintaining decent filament. Thanks for the great input Alan
  3. The engine modelling looks wonderful. The detail is excellent Alan
  4. What did we learn today Today I stepped back from the model to focus on the printer quality. I used the Benchy test print. It has a lot of good test points in it. Overhangs, openings, thin vertical sections. It only takes a couple of hours to print and its a bit of fun. So on the left is the first attempt. The filament ran out in mid print but it was already looking bad with all the strings at the stern. The middle print was a straight repeat with new filament and a better result but a bit ragged still with stringing and extra filament at the openings. At the base of the stern there is still a lot of extra filament. At this point I went back to the Cura slicing settings and noticed that I still had the settings I had made in an attempt to improve bed adhesion and print integrity before I found it was under extruding. I had reduced the layer height to 0.12 mm (from 2.0 mm) and increased the infill to 100% (from (20). I also still had support generation turned on, and brims. So before trying anything new i reset all the inputs and generated the boat on the right. This is quite a decent print; no stringing, the stern is clean and its possible to see the boats name (really) The print with revised settings is at the rear. This looked quite promising so I attempted the test piece Astro Phil (a-ment) This printed very cleanly; the edges of the boots are nice and sharp and even the treads came out well. I decided to re-slice the recent 4 inch and 2 pounder gun parts but Windows decided that the afternoon would be better spent installing Windows 11 instead. So we wait in suspense until tomorrow - its curry night tonight so the printer is OFF. I hope everyone has a great weekend Thanks for looking Alan
  5. You are making a beautiful model from a very basic kit. It looks lovely Alan
  6. Ziggy If you send me an address I'll be happy to send you the remains of the Wasp air wing - AV-8Bs and helos Alan
  7. Really looking very nice. The details are beautiful alan
  8. A super interesting subject. This will be a spectacular model. Congratulations for taking it on. Superb start Alan
  9. Yves; Thank you very much. I think even a basic diorama sets the model off and they are fun to make but they take up so much extra room Alan
  10. Thank you Mike. Very kind. The Eduard PE really makes it a better model. Next - I want to progress the Flower corvette but that will depend on how much sense I get out of the printer trying to achieve decent deck fittings and weapons. Otherwise it will be back to 1/700 - maybe WW1 Alan
  11. Thank you Lou. I'm glad you enjoyed following along. It was a very enjoyable build for me. This one now lives in pride of place in the reading den Alan
  12. Thanks Dave for all the great comments I spent two deployments on board as a flight test lead so its been a treat to be able to create a decent model to stir the memories (well everything except the Swedish meatballs maybe) Alan
  13. Thank you Ian. I'm still learning how to model different sea states but its fun and relatively low cost to experiment. Alan
  14. Thanks Yves I think you are right - the resin printer is a necessity for some of the parts like the secondary weapons, Selfishly none of my friends seem to want to buy one😄 I'll try the slower speed
  15. Hi Kevin Thanks for all the helpful comments. It is becoming apparent that the finer parts of the Flower build are really falling into the territory of a resin printer. Having read other threads about them I have been increasingly interested in buying one and had been thinking about the Elegoo range. This months donations go to the Homeowners insurance, the iRS and recent UK travel but I'm hoping for a quiet month next month and Amazon must be wondering if I'm still alive so ............... The idea of a combo printer would be fantastic if it can manage the size of the Ender 3 or better. In the short term I downloaded a number of test prints and I'm working through them to see what i learn. One possible early result is that my preheated filament may still have been too old or less that perfect. It ran out during a test print and the replacement filament seems to be doing better. Reading suggests that the massive printing exercise to make the hull parts should have worn the nozzle so a change will be part of the plan I'm also going to look at retraction and layer thickness. Thanks for all the help Alan
  16. I think thats a great idea OC. That will transform the hedge from a well manicured garden hedge into a truly rural one with irregularities and trees and bushes growing in it. Great Idea Alan
  17. I used the Vallejo foam effect to add some 3 dimension to the wakes and wave caps. I'm a bit disappointed in it - it just seems like thick white paint. It does set very white though. I could have spent a bit more time fiddling with the water line but I was starting to knock the PE off and decided enough was enough. The model has been placed and after taking photos the display case is in place. Nothing left but the proud parent photos. Many Thanks for all the comments and likes. This has been a great adventure for me probably the hardest model I have attempted and I have enjoyed the whole build. Still lots of areas to improve on but its still a fun journey. Alan
  18. Slowly moving forward with the foredeck. Most of the fittings have been painted and the steam winch has been assembled The hatches and bollards are in place. I have ventilators and the chain leads to add and well as hose reels. Overall it should look quite reasonable when the paint is tidied up and some weathering is added. Although I am getting better print quality now I am not happy with the detail in some prints. I don't know if its file errors or printer settings. But there is extraneous filament build up in places. As usual the choice of culprit (if its the printer) is wide. Printer speed, extrusion rate, nozzle temperature, nozzle size. etc. And it could be the filament I'm thinking of investing in some smaller nozzles to try that out. The pictures show the halves of the four inch gun and the 2 pounder aft gun. You can see the rough quality of the printing especially in the 2 pdr. So I am printing test prints now to see if I can improve quality - back down the rabbit hole for a while. I am not convinced that I can print the Oerlikons acceptably even if I can up the quality so I looked at Micro Masters. They have a four inch gun in 1/48 at $129 the Oerlikons are $30 and the 2 pdr is $40. I will wait and see how the rest of the ship comes out before committing too much to get one or two parts looking good. Thanks for looking in Alan
  19. The mast and arrays are spectacular. That sets a standard to aim at. Alan
  20. I used acrylic paint to add the wake and the bow waves and occasional white cap. In the background I removed the Wasp from the build base. The heavy duty double sided tape was great for holding teh ship firmly to the base but separating them was a bit scary. Steady gentle pressure got the tape peeled back. In future I'll used smaller pieces A coat of gloss medium was then added to give depth and bring it to life The big moment - a trial placement of the ship I need to add a bit of disturbed water at the waterline and some more foam in teh wake and I think I will call it finished Thanks for looking Alan
