Re: STFM case remake
Maybe need a sticker on the door "Do not enter on punishment of death" or something. ..

Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~
People should find solutions to problems, not find problems with solutions.

Re: STFM case remake
Sorry @Icky only just seen this, will have my fingers and toes crossed for the next one.
BTW, I know its a waste of filament but maybe try a more solid raft first and if nothing else board up the lower half of the printer to stop drafts directly on the print.
Oh and before I forget, did you also try levelling the bed when it's warm? Might be bulging very slightly in the middle?

If it ain't broke, test it to Destruction.
Re: STFM case remake
Yeah the printer has a complete chamber but I didn't have the front panel in place correctly. Plus I have noticed a few gaps where it will be drawing air through that need to be sorted.PhilC wrote: ↑Wed May 27, 2020 6:52 pm Sorry @Icky only just seen this, will have my fingers and toes crossed for the next one.

Yep levelling is done at temperature as the plate is large and you need to do it once its all at temp.
Re: STFM case remake
More progress. @exxos has a pink STFM bottom part of a case - https://www.exxosforum.co.uk/forum/viewt ... 850#p40589
I have been printing out sections not the whole case as prototyping continues. The current print is the section of the whole left side of the bottom case and the print was a bit scrappy because I wanted a fast print.
However it has showed a few things. There is a stress point on the cartridge bridge that breaks easily. I had a look on a real STFM case and that area is pretty much the weakest point on the case bottom. The point broke when lifting from the printer bed. Will be shoring that area out to improve.
In addition we have been making some of the mount points use threaded inserts similar to the newer STE cases.

Re: STFM case remake
Looking good! Yeah I think a few places will need tweaking to make it less breakable.

Re: STFM case remake
Small update. As we have been printing prototype sections to make sure all the posts and ports are in the correct position we are starting to see certain areas where we need to make some slight modifications to improve the quality of printing of the case. We have always said this is not going to be an exact match of the original but an approximation to look like the original and allow a motherboard to be housed.
One example is the front grills. They go from flat and angle upwards and this is a potential area that on every prototype we have printed is scrappy. We are going to introduce a small thin bar along that edge to improve the print, make it stronger and keep the aesthetics of the case.

Re: STFM case remake
A quick mock up of the thin bar in place. When the case is flat on the desk it doesn't look very much different from the original.
Re: STFM case remake
Probably not a bad idea anyway as the front gets easily chipped.

Re: STFM case remake
Well we have been printing lots of prototype case bottoms as we keep getting break points in the same two places.
The last run I did on a full case bottom, which took around 29 hours, had to be halted due to one of the break points actually coming away whilst printing, even with substansial supports. This is not the first time this has happened so they are definitely the weak points which need to be resolved.
So although its not a full print and has a nasty extrusion on the back right all is not lost as this helps to confirm our thoughts on a removable (slot in) back panel to allow printing of different port layouts, such as accommodating an H4 with the stacked Phoenix Shifter board having a HDMI out slot above the original ST monitor slot or other options. The removable panel will elevate that weak point and allow for improved printing.
In addition the full case has shown almost all posts etc are in the right place. Just the front three post need to be moved 3-4mm towards the front a bit more.
Well @exxos now you can get a sense for what a pink ST will look like

Re: STFM case remake
Looks great. It looks like the walls are a bit thicker then original but maybe my eyes plays some trickery on me.
