First layer of ASA didn't stick to the bed so I've increased the temperature from 100°C to 110°C and trying again.

I'm also going to try a change in the model. The greatest curl or lifting off the bed is when the item is high at the extremities. This ti the model I'm going to try with the ASA filament. This should test two things at the same time - the use of ASA and the change of model.

This is definitely not acceptable. Maybe I'll try the ASA and see how that goes. Settings are supposed to be similar to ABS but with a lower hot end temperature.

Still getting curl and separation from the bed in spite of brim This is with the blue ABS. 8MM lift out of 24mm.

Ah yes, that could be the problem - I am using more powerful (longer) NEMA 17s in my Titan printer. The ones in the Pilot aren't the smallest either.

Now making a test print of the bracket and ASC base which will take 2½ hours. Meanwhile here's a photo of the present casing and anemometer.

Wind sensors casing.

Wind sensor bracket and base of ASC. Could be a bit longer and still fit on print bed.

mp4 link not working Not sure I would be happy bashing the nozzle tip onto the bed. I can see why you want to make your machine quieter Dave.

I use a brim a lot but thought this print had enough area to stay put - I was wrong!

Since I'm no longer making the casing and bracket as one print, here is another idea. With the anemometer moved further away from the ASC, the affect of the ASC on the anemometer should be much reduced and only with the wind in a particular direction. It makes the construction much simpler.

This would be the sort of look. Probably the top image - reprinting as little as possible (I haven't printed to casing of the latest ASC design yet).

Apart from the curl which reduces the strength of attachment to the mast, the print is pretty good. But that curl does make the item unusable as the top (bottom in printing) is not at right-angles to the mast. A complete redesign is indicated. I think I shall combine the bracket with the bottom of the ASC. Also, although the size of the hole is a nice fit on the aluminium tube I'm using for the mast, I think I shall add a clamping arrangement. I might change material for the final print. Two ideas on this - PET-G for its greater strength or white ASA for it's UV tolerance. I guess the UV resistant ASA wins overall but I've not used it yet so will need to change the print settings and do some test runs.

Talking of bed - I'm for mine

Finished! Without coming off the bed

75% and still stuck to the bed. The curl is horrible!!!

Hmmm... 2/3rds printed and the curl is really getting serious with less and less still in contact with the bed. The print is liable to fail due to coming adrift from the bed before it's finished Looks like I may have to print it in two parts (making three parts including the bottom cover). Guess I could try with higher bed temperature.

15mm printed and the mast end is about 7mm off the bed Other end is about 2-3mm. Probably have to reprint it using brim - I think it will just about go on the bed if I move it a few mm towards the near left corner. I'll let this print finish as I can use it to check out other things. There's quite likely to be something else wrong with it

Print is showing rather a lot of curl at the mast end Just a little at the other end.

Here is a new design for the main casing. Bottom view and top view. The hole near the mast is for a USB cable to connect the Arduino Nano to the RPi in the ASC. There will be a tube glued onto this casing going up the the ASC casing. This will also provide additional support and stop the wind sensor unit from sliding down the mast. The notch in the side of the hole for the anemometer and top wind vane axle bearing is for flat cables from anemometer and rotation sensor. Printing time for this is 2h 37m and will use 49m of filament.

Two possible colour schemes depending on which filament I use for the main casing. I'm running a bit low on the green.

Printed a new pillar half the height. I think this looks alright. Anyone see any problem with this?

This pillar is actually 20mm shorter that the earlier one but still looks higher than needed. Very plain, just a cylinder but it doesn't really matter what it looks like at 6-7m above ground. The inside of the pillar tube well clears the the wind vane sensor assembly and leaves plenty of room for the wires (multi-way flat cable).

Holder for top bearing printed satisfactorily. Now printing the anemometer pillar (just for a change ).
