Hi Gents two more randomly stupid questions for you. I followed Paul suggestion and printed a wagon at Y axis 45 degrees and there's a an excess build of resin along each edge on the lowest side. I have tried to photograph is but it really isn't showing up very well. Should have said cure time 2.8 sec's. Any ideas to the cause? I am also trying a second print this time using a 2.9 sec cure and a 46 degree X axis, its printing now. Daft q2. I have been happily creating the drawings for a brake van in Fusion 360, and for no apparent reason none of the sketches (new or old) will allow me to extrude. I have even tried closing and reopening 360 to see if that clears it. What's going on or is my brain frying. Mossy
Usually when Fusion doesn't allow extrusion it's because the object isn't fully enclosed. Does it turn blue when you hover your mouse over the object? If not you need to zoom into all your line joints to make sure they are actually connected to each other.
Been there done that trick and I just can't find the missing connection which is why I assumed there could be something else. In the end I have copied all the dimensions and started resketching it, along with the obligatory deliberate mistake, just to hone my correction skill further! Mossy
Hi Mossy Not to sure of the cause, but try adding additional light supports, if it appears like a series of steps then it maybe the print angle. Paul
Very useful.. although he demonstrated supports but not to the edge. I’ve found crisper edges with supports at the outer edge, not stepped in as the auto generators do.
Not had time to watch the video yet Andy, but I have dumped auto-supports - frank ^&**%$. I have started concentrating on red areas, but then move on to get supports as close to sharp edges as possible - so we think alike! Other areas which seem well connected to the rest of the model just get random supports added last. Mossy
Re posting #65, I set the print running this morning before an excellent walk in the Yorkshire Dales. It's just been degungded and then had an 8 mins wash. The odd feathering from post 65 is still there but obviously there's far less of it as the wagon was angled 45 degrees on the short side. I think the best things to do are a) watch the video and b) assuming it doesn't provide a magic answer go back to 45/45 angles, and 3 sec's cure time - they gave the best results. All that for tomorrow as it's time to eat. Mossy
Watch the video.. he says what I found. 45 isn’t always the answer. I tend to print square on, but mindful of FEP pull. Oddly it’s mid print where I’ve had fails or straight after the support raft oddly? Which I’ve not seen anyone explain away other than “slicer error” which it obviously isnt as it carried on else where. Good luck. Andy
Does anyone have the link to the O gauge guild video on scaling (its part of the 3d printing special group I think, but I have had no luck finding it on you tube. Cheers Mossy
Hi Mossy If thats the last session where Chris loaded an image then calibrated the image to size then that's https://www.gaugeoguild.com/events/specialinterestgroups.aspx Sorry I think it only works for Gauge O guild members. Also found this video which covers the Mono FEP replacement and a replacement Vat that allows the standard FEP sheets to be used instead the drop in replacement FEP units (currently available from Anycubic site at $11.99 for two). See links at the bottom of the video post for the Vat and replacement FEP links. Paul
A thoroughly daft question that I should know the answer to: What's the distance between the railhead and the centre of the axle - in 7mm?
And the stupid answer is depends on the wheel diameter. Just measured up a GWR wagon with split spoked wheels, diameter = 21.7 mm at the mid point on the tyre, so the distance to the center will be 10.85mm Paul
We went walking out in the Dales last Tuesday, I was utterly convinced it was Saturday. Erindoors just kept shaking er ed and muttering darkly. For 50+ years the only days I went out rock or ice climbing or walk were weekends (leaving holidays aside), I was walking therefore it must be Saturday - simple but wrong.
