Thank you @sarahv! Could we also get one for tc-receiver? It looks like that one got missed since it wasn't in the description with the rest.

samantha closed T2047: TechDraw Template doesnt match Aleph Objects standardized template as Resolved.

Took care of this since drawing dimensioning no longer works with FreeCAD 0.18 and thus we needed a functional template for Techdraw. Turned out to be some extra things inkscape had in the file that Techdraws SVG interpreter couldn't comprehend, such as translations. Solution was to go into inkscape and select all, delete layer, paste in place. This essentially resets the objects to de-link them from the weird code. This solution was taken from the tutorial here https://www.freecadweb.org/wiki/TechDraw_TemplateHowTo

samantha added a comment to T10176: Industrial Design.

Josh and I met with Randall at Epocs this morning and went over the currently modeled sheet metal. I emailed him the LCD enclosure front for a little further review he will have with the press brake operator tomorrow morning, but aside from that he loved all of the current sheet metal designs with just a few very minor modifications to better fit their tooling to save us some money. They also can hit our timeline for Alphas if we get them RFQ next week and place the order quickly once we have the quote.

samantha added a comment to T10257: Filament spools internal to machine.

We had a spontaneous meeting with @eBeardslee and settled for now on making the machine a little taller (estimated 210mm), and having the filament under the machine, in the front, using some of the spare space under the bed there. We are working on this presently.

samantha added a comment to T9875: Z axis alignment.

I found the tslots cut squareness tolerance, which is 0.003" per inch. This gives us an angle of 0.20302 degrees on the short side (30mm) and .406026 on the long side (60mm). This gives us 0.885846 and 1.77167 difference over the 250 travel, 1.77169 and 3.5433 over the 500 length of the extrusion.

samantha updated subscribers of T9875: Z axis alignment.

@cmerot a machining tolerance per ISO 2678 for a 30mm length is 0.5° aka 30'. so, if we aimed for perfect that is our realistic worst case scenario, which is what we need to plan to see. Over the Z build volume of 250mm that alone would cause a difference of 2.18mm. Since we would be leveling the bed to the head, what this would result in is the print shifting by that 2.18mm over the range of the print. We think we need a different solution than just trying to machine the surface of the extrusion perpendicular to its sides.

samantha added a comment to T10257: Filament spools internal to machine.

@eBeardslee We had considered trying to mount spools on the back, but that may be a tipping hazard. Additionally, it may be hard for users to get to the back of the machine if its up against a wall. It also would need to have a 90 degree angle spool arm in order to fit the spools. The footprint would also be considerably larger. None of those are necessarily stopping points except for the first one, which is unconfirmed.

@eBeardslee @Greggb please see Tyler's comment above and confirm if you still wish to go with internal spool holders as the default configuration.

samantha added a comment to T10252: Thicken top plate.

From Christian, for our situation "the ratio of stiffnesses is [(thickness-top)/(thickness-lower)]^3. If the top plate is more than 2.15X the thickness of the lower, it is about 10X as stiff."

Per T10176 we need to look into options for machining the end of at least one of these (z axis rail) to sit perfectly on the top plate, and also put in shoulders to locate against dowel pins in the top plate
