samantha added a comment to T9587: Toolchanger/dock weight limits.

E3D has said that they can do 500g, or 1kg with the motion slowed down, using their motion system. Those were limits of the motion system though, so potentially more could be done. Additionally, the spring could be changed out to increase the weight limit even further.

@kent I don't see making drawings for every commodity screw and washer to be a very reasonable request. I think instead we could capture all of the information for that inside of a BOM in an assembly drawing such as the one requested in T9251, or through another means of declaring the standards that apply instead of making custom drawings to global standards for 32 commodity parts.

Several of our vendors remake the CAD files to work with due to poor compatibility with the FreeCAD generated files, from what I have heard.

samantha added a comment to T8896: .step files issue (corrupt?).

According to diff, the hibiscus repo file and the kangaroopaw file are indeed identical. The only difference between those files and the re-export I had done are the filename and time/date of export internal to the file. Therefore, I suspect the re-export did not solve the issue, but one of the other file types did. Can we ask them to check what worked for them before?

FreeCAD cannot do parasolid. We only have iges and step for options that shops are likely to be able to use. We can see if they can work with iges, or try a fresh export of step to see if that works better for them.

I cannot see T3450 in order to check the history on this. I believe I recall that being closed as we were struggling to hit demand at the time and it was determined the change at the time would hurt that temporarily, which we wanted to avoid. If it is still an issue and we are at a better place to handle it now, that seems like a good thing for CO.

@cmerot As this seems to be something that will occur on all machines under certain conditions that just happened to be noticed on the floor just now, I was asked to have you weigh in with your thoughts on how we should proceed with this.

samantha added a comment to T8068: Pro makes loud clicking noise when homing/auto leveling and x-axis is not level.

This seems to take excessive force to rack it enough to have it happen. It took me a while to replicate, I have to strain a little to make it happen, and I can't do it reliably. There was a theory that it was due to the tab on the Z upper deflecting, but I have taken some videos and that appears to happen regardless of if the click happens or not. This click is a sound I have heard before occasionally in prototypes, and I also just tested another production unit we have over here, and I was able to get the clicking even prior to reaching Z-max.

I have received confirmation from BASF that they see various options for sintering environments, but the catalytic debind has no alternatives for their materials. They did say however that they intend to sell the filament with a deal from their own sintering vendors which you would just mail the printed parts into, instead of expecting people to invest in the equipment and testing.

samantha added a comment to T6691: Sintering kiln or furnace.

According to the BASF Ultrafuse 316LX datasheet I am looking at, sintering can be done in pure hydrogen or vacuum, so we can probably do that with the same furnace in vacuum. The vacuum furnaces that I am seeing are also listed as able to do inert gases. For hydrogen, such a furnace would require additional safeties. I think we should stick with vacuum unless we have need to test gases, just for the sake of not dealing with the gases, but we would have that ability. The BASF material does use a special debind process that also raises concerns due to airborne acids, but in theory could also be done in the same type of furnace. Virtual Foundry materials seem to do a thermal debind that is just contained in part of their sintering cycle, which simplifies things a lot.
