Here we go

Haven't looked at mods to make it Kadee compatible yet. One step at a time.

Thanks to Keith and his talented son.

I can do a few, as is and for Kadee, but .... I ordered different strength springs for the build platform from the dealer.
They come by expedited parcel post but so far the tracking tells me:
2018/11/14 00:01 Canada Delivery may be delayed due to labour disruption
2018/11/13 00:01 Canada Delivery may be delayed due to labour disruption
2018/11/12 00:01 Canada Delivery may be delayed due to labour disruption
2018/11/15 16:01 CONCORD, ON Item picked up by Canada Post

It's that patience thing again.
#:-s #:-s

Since I'm always interested how others do it I signed up with the German language Creality Ender 3 FB Group. Turns out some smart German cookie produces silicone dampers (in lieu of the lousy springs). From those who use them: Align the build plate to specs and get printing (instead of leveling and more leveling)! Have them shipped to Switzerland and SWMBO will be the courier.
Yep, off on yet one more holiday. I keep teasing her about her carbon foot print ... to no avail!

Looks like you are getting a real handle on printing - The leveling is just a start point, fine tuning as you go seems to be the best solution. I have even found that different colour filament behaves quite differently, red seems to have a different property to the others, all to do with the chemical composition I suppose. Remember to store your filament in moisture proof containers, in a bag with a pack of silicon gel works. it you don't - you get a very uneven flow from the printhead with blobs and strings rather than the steady delivery. Should it happen, the filament can be recovered if left in a warm dry place for a few days.

Yeah mixing/trying filaments from different makers is "interesting". I'm sure it will get even more interesting trying out TPU and PETG. If luck strikes I should get the stronger springs in the next few days. :-w :-w Getting some stability when traming the build bed will be welcome, being able to print some of the gizmos to make printing flex materials possible the next benefit.
How am I making out with Fusion 360? No progress since I need to get the printer sorted first.

Oh yeah and then there's XC skiing, four days last week (first week). B-)

Double seal ZipLoc bags together with Dry-Packs Silica Gel Desiccants are on the list for the next order. That should work.

New stronger springs arrived. Install, adjust, test print. Turn off to go skiing, fire up the printer on return. Same test print A-OK
Test cube yesterday, all working as it should.

Now the fun can begin without all the bother. B-) B-)

Yesterday was also a rest day — getting SWMBO off on the way to CH. :| :|

Now enjoy, did I mention you should not touch the hot end?

Yes, when I mucked up the nozzle I just removed it and took the miniature BernzOmatic torch to it and got rid of the gunk. ;) Several times when the table decided it was time for extra "entertainment".

I think this will be quite a productive method to build some of the extras to go with the stuff coming off the laser. Ordered some wood filament to produce Euro palettes, got the STL from a buddy.

Wood filament is very rewarding but a bit of a fiddle. It does not like sitting in the hot end for long and will discolour if you let it. If you can, use a larger nozzle and slightly lower resolution to get a wood grain effect.

Wood filament arrived! Installed the 0.6mm nozzle, double checked the bed level, applied some hair spray cranked the hot end to 240, bed to 70 and now watching the build while doing other things. Even if it doesn't turn out, consider it a wrecked pallet. :ymdevil:

How did it go? Surprisingly well, but with a lot of stringy cobwebs.

Image

Brought on by all the "jumping" when the spacer blocks between the top and the bottom are printed.

Comparison pictures 3D (LH), real wood (RH) the top and the bottom.

I like the texture and the colour once it's cleaned up. Of course the big advantage: when I wake up at night I fire up the printer, watch it to finish the bottom layer at low speed, crank it up to running speed and head back to bed.
On account of the minimal layer thickness it takes quite a while! But who cares, one can either sleep or work on some other project.

In my opinion it looks like a skid that has done some work, a wash of really thinned Acrylic grey will do the rest.
Now it's almost time for breakfast, after the re-baked bread has cooled down


PS SWMBO is off on her annual study trip to Switzerland, this year the group goes to Leipzig. Getting there and back? Strictly by train, a lot smaller carbon footprint!! :ymblushing: :ymblushing: This while I traipse up and down the mountain by car, if at all possible ..... four days a week.

Suggestion to minimise the strings - put a 0.5mm wide strip, same depth as the pallet along the bottom - yellow line below - it will allow the print head to follow a path without retraction and you can cut the 0.5mm strip off when finished printing.

The strings are history,

Image

My buddy in Germany, who provided the STL, told me the values he prints at. ;) ;)

Have one or two problem items out of nine? No problem, do a bit "extra" for a ruined pallet.

For the wood filament I'm still using hair spray to make things "stick".

210º/70º 0.2 layer. On CURA the "extra fine" selection. BUT I'll be trying a faster version next.
