Mossys 3D Models

It sounds like we both are having problems. I went back to an earlier version of the autocar, and reapplied the changes, through Chitu supported sliced, so I knew everything had been changed. Warmed up the X2 and fired up a print, my 2 hour check - exactly the same problem, ^&*(*%$, yes the air was blue, especially since sitting on my desk in an early print of the body, created without any problems, except the bits I had missed off. No idea why so I am going for a total strip down today. Then print a different body that I know works just to eliminate the printer from the problems probably use the 5 squares test if I can find it!

I use the same process and Paul. I think, Paul will correct me if I'm wrong, he put me on to it but was only warming the resin, I started warming both resin and build plate and he picked up on it. I use bath hot water and boiling water in a roughly 2:1 mix, and again sink the dried build plate into the resin for 5-10 mins before firing up a print. It works a treat.

I wish I could figure out what's going wrong with mine, I ran a test with a wagon that I have printed multiple times, same failure. The only thing I can come up with and bizarre is temperature. All the successful prints were done in the summer using the old preheating by dunking in hot water not using the thermal heating band, so this afternoon I am going back to the old way of doing it with hot water pre-heating.

 

Hi yes they aren't supported all the way along they sit on mounting plates which are .35mm thick. When I was printing the body/chassis as a composite I ran a line of light supports along the outside edge to hold them in place. I don't think that would be feasible with a huge incline line your print I think the light support would fail. Sorry I should have warned you about this before you started printing. My latest test failed miserably so I am completely at a loss what the ...... to do next.

 

Mossy speaks with a forked tongue, they sit on little triangular supports and are off set by .35mm.

 

Paul,

Your a gent, did I supply you with enough resin or do I need to order up some more for you? What's next is for me to print the ^&*(% bodies and get the thing built. I hope you have learned a few things about your new toy that will come in useful later down the way. My next task is to get back to my Class A loco, but some time next year I have 3 other coaches with the designs almost finished, if you fancy more chassis/roof jobs. They are smaller than the autocoach, built on 49ft chasses not 52ft, so saving the printer 21mm, what's that, a whopping saving of about an hour?

Paul asked what's next well. For some reason I woke up at my old working get up time of 4:15 this morning so I have had plenty of time to think on how to progress the autocoach body after over a week of failures. The new plan is to use my trusty old Mono, which hopefully hasn't got the same problems as the X2 (time will tell). Printing a left and right half of the body isn't possible the build plate isn't big enough, but it is big enough to do the print in 3 sections, left, right and middle and amazingly it does allow a different strategy. The old way meant the join ran directly through the middle of the panelling and would required an awkward clean up and fill job. The new way I can slice up the body into 3 directly through the door cuts so any clean up will be in one plane rather than two. I think I talked this through with Rob on a different print about 18 months ago but forgot about it. The second advantage is I can fit the two end section to the chassis first and then do each middle section separately meaning I am not juggling one side against the other. All good plans etc, fingers crossed.

It proved remarkably simple to chop the body in to three, which actually gives 4 bodies, left, right and 2 middles. Three print runs of about 4hr 15mins a 50% increase but after all the lost time what 4 and a bit hours, so they are now sliced and diced in Chitu and ready to print, wish me luck. These are the 4 bodies, the thin line visible on the middle section is where the old join would be.

 

Having chopped up the body into 4 bodies, I dug out my old Photon Mono to do the prints, blow me it refused to read the memory stick, so I tried a different one, same result. Tests with 3 more memory stick all failed, conclusion the old mono isn't a happy bunny. That left my recent purchase of a Mono 2, I haven't been happy with this simply because Chitu doesn't support it, I hate Fusion Workshop and detest the complexities of Lychee all un-necessary, which left me a big problem.

Experiment time, use Chitu to support the model using the Mono profile (wrong size, bits hang over the sides, will it work), then save as a .stl file, open up fusion workshop, import the .stl and get it orientated correctly, slice and blow me that bit worked, but what does the printer make of it? The printer chunter away for 3 1/2 hours and we have a print, sadly a few supports failed (mea culpa), so a quick rebuild and a new print. I'm a happy bunny, a really nice detailed print of 1/3rd of a coach and a way around thigs till I figure out what's wrong with the X2. Piccie to follow if/when the sun gets around to my photography post.
