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.

the thing is if we have PEEK on the nozzle it would need to melt the PEEK to clean it, which would melt the bristles.

mjpelletier added a comment to T9524: Pogo pin lifespan.

Not SD Card fingers but fingers that can be mounted on one circuit board. They would press against pads on another circuit board. The spec sheet for AVX 9155-000 series states only 5000 mechanical cycles. If you anticipate changing the print head many times during a print, a connector with 1M cycles would be more appropriate.

tutley added a comment to T9524: Pogo pin lifespan.

It says up to, so does that mean it is normally less than that?
Going off 1,000,000 cycles, a print that is the full z build height with a .5 nozzle will likely have layers somewhere between .1mm and .35mm
if .1 then that is 4500 layers, meaning you could print this 222 times before the tool head needs a new pogo pin board
if .35 that is 1285 layers, meanig you could print this 778 times before needing a new pogo pin board

Probably an IT ticket for Kaleb.
Asking our suppliers to use git has typically garnered us very blank looks. Putting these online avoids sending huge email attachments and can simplify having multiple old revisions floating around in supplier's emails. We had punted this until we had a better idea of what we were going to call this so we could put the development material under the name of the new line. Now we are having issues disseminating our drawings to suppliers.

E3D has been using a wire brush on their tool changer test fixture. With hardened steel nozzles (or some other abrasive resistant material) we wouldn't have to worry so much about wire brushes damaging the nozzle.
I'm not sure a non-stick (Teflon) brush would actually clean anything off the nozzle, but I could be wrong.
