pps, so my conclusion is that both parts of a 2-part switch chair are "owned" by the stock rail rather than the crossing rail.

@Steve_Cornfordpps, so my conclusion is that both parts of a 2-part switch chair are "owned" by the stock rail rather than the crossing rail.
@Steve_CornfordI thought it sensible to subtract 5mm all round from the build plate size to calculate a maximum raft size, is that about right?
@Steve_CornfordIt would be convenient if there was a way of adding some text to the raft to indicate the spec. eg EM-B-LH.
@Steve_CornfordJust hope you dont run out of boiled eggs before cracking the remaining chairs ,or you cease getting enjoyment out of your development hobby.
@AndyBWhen I read that as "WEST AMERICAN EM GROUP" and I thought it could be interesting as they must be too far away. (And that's with my new specs )
@Steve_CornfordWhat software are you using to display that image?
@Terry DownesI'm now trying to export the 3D stl file for the chairs to print on my Formlabs resin printer. I'm sorry if you have told me this previously but, I have looked through the various threads and can not seem to find the answers. I'm able to export the chairs as an stl file but,
a) is it possible to reduce the chair supports to 1.6mm so they do not protrude below my 1.6mm ply timbers?
b) how do I bunch-up/compress the chairs (timbers) so the resultant stl file is not so large/widespread?
Hi Steve, yes, that answers my chair bunching query. Many thanks.Hi Terry, suggest read from page 22 of this topic where Martin gives us a clue to using partial templates etc, then group & copy that set and shift by say 5mm to interlace the second set, as bunching not yet available, you need to move the two parts of the two part switch chairs apart so that they print separately
@Steve_CornfordOr even separate loose keys for the check rail might be doable if we print some sort of holder to handle and insert them -- we could then have a 1-part chair on the stock rail, just like the prototype.
I can see more tick boxes arriving shortly
@Steve_CornfordHi Martin,
Looking like another step forward and definitely deserving of a boiled egg for Sunday breakfast!
I am using the label facility when 3D printing a raft of chairs in resin. Would it be possible to make the characters a bit more embossed?
By that I mean a bit more extruded from the surface or is that too complicated?
On the FDM timber brick in your most recent post they seem a lot more embossed.
Or is the degree of embossing related to the font size?
This is the closest I can get with my camera. Although not visible to the naked eye, you can see that the loose jaw is not quite sitting flush to the chair base. I thought the pin might be bottoming in the slot, but shortening it makes no difference. I thought the rail might be lifting the key, but removing the rail makes no difference.
So it must be some shrinkage distortion. I think it would get lost under the paint, but even so it was annoying me. So I have put a slight saucer relief around the slot in the top of the chair base to accommodate it:
