Hey all, I reached out to 713maker to see if it would be possible to create a magnetic bed for the e3d toolchanger. This was done before and discussed in a different thread (https://forum.e3d-online.com/threads/glass-bed-vs-e-g-buildtak-flex-plate.3490/page-2) by @garethky , who provided a design but ended up having xometry make it. The design by @garethky is viewable at https://cad.onshape.com/documents/8...fc829362336d52c230/e/cc90854da771fc50efdb384d And a quote from the thread linked above: Extending the lip on the front of the heat bed from ~8mm to 25mm. This should give a slight increase in printable area or just more space for purge/wipers. Front corners of the bed are inset and notched (like the Prusa bed) to allow the build plate to be lifted up easily. Mounting slots are shortened to 1mm inwards from the nominal mounting hole locations. The bed will expand slightly corner to corner (my layman's math say ~0.7mm from 25C to 150C), so 2mm should be enough play. The oversized 4mm holes are retained and there is a countersink so you can use a 3mm socket head cap screw and washer for mounting and that will all fit below the print surface. Thermistor slot in the top of the plate so it is closer to the print surface and therefor more accurate. The nominal build plate dimensions would be: 318 x 233. I don't actually know of any commercial ones that size. I'm using 300x300 plates. 713maker got back to me a day or two ago and is ready to make a prototype but we need to quickly decide a few things. The number of magnets and spacing will be determined by 713maker to create a similar pull force to the railcore design. But I want to hear opinions on the following and whether you'd be interested in buying one. footprint - I'd like to see if there's a flex plate already available. I think a few people are using something like this: https://www.aliexpress.com/item/1005001270710359.html?spm=2114.12010612.8148356.1.26f95f42OovHzY Buildtak has a 215x304 to fit the BCN3D Sigma mounting solution I don't see any issues with the design but am interested in your thoughts. thermistor channel - top or bottom? It seems like cutting a channel in the top would impact the temperature distribution in the flex plate. Maybe someone could run a simulation... would depend on the thickness and thermal conductivity of the flex plate. And one last thing... we'll need to stick a silicone heater on this thing. I have a keenovo heater on a different printer that smells sooooo bad. Is that typical with the adhesive applied heaters? How are these bonded on the e3d bed?
