heated bed for cube3D

[Kiza]

I think ztodd's idea is to stick the heating pad to the under-side of the OEM plate, with clearance for the magnets and platforms they ride on. I love it!

Doesn't add thickness, easy to install, allows someone to easily add their preferred bed on top (or leave OEM). If Keenovo can cut these 3 holes to a high degree of accuracy, this would also serve to secure the plate against x and y axis wobble.

I am SO in. Fire it up!

Another idea - A switch could be hidden in the "cup" of the printer base that would tell the controller that the print completed - turn off heated bed. No need for timer or any other clever solutions.

Another option can be sticking the custom made PCB heater on the bottom of the OEM print surface, with the same 3 holes, that will act as stabilizers.

Hey Ztodd, how goes it? Please PM me when you are ready to purchase initial batch of pads. I am in for two.

"With this coming into light, I have to step back and rethink how I want to control it. 24V, 12V, 110V??"
IMO, full 110V is overkill and not worth the added risk for such a small bed. My vote is to use 24V.

That InkBird controller appears to be an all in one 110v controller? It has the SSR built in?

I would also test one! Love the idea of getting back the original print bed.
My setup is 24V
Also we need to source the proper strong magnets and glue.

AFter the initial email, seems like my follow up email to them got lost. Kiza, do you have a file to get the exact location of the magnets? Im hesistant to "draw up" a template of where to put the holes.

Centers of magnets are 32mm apart from the center of the bed, both horizontally and vertically. Bed size is 170mm x 170mm.

Currently I'm using 160mm x 160mm silicon heater, without holes.

I can produce AI/DXF file, if needed

The magnets are actually placed on the English system IIRC.
This should make a good template - it is a perfect fit at 100%

that would be great Kiza, I know what a dxf file is but what is ai?

perfect. I'll send out another email to them with this attached to see what happens
