Choosing a suitable power supply

@mrehorstdmd said in Choosing a suitable power supply:
I recently put a kinematic mount and new bed in SoM and mounted the TCO on the heater using a blob of high temperature silicone. That's the safer way to do it, I think.
That's also the way how Keenovo does it if you order the heater with a TCO. Or actually they put it under another layer of silicone but that's essentially the same.

@mrehorstdmd Right. Good warning. Was that with the 3M adhesive sheets or was it bonded with RTV silicone? I can't remember. I've bonded my heater pad with RTV silicone, that should last a lot longer than a sticker sheet. I remember seeing your post about the PEI sheet lifting when the 3M sheet lost it's bond.

Hi, could you elaborate regarding RTV Silicone ? I am suspicious about adhesives and would be interested to know more. Do you by any chance have a link to a product ?
Thanks

But there are many options and types. It's also called gasket maker.
I cleaned both the aluminum and heating pad thoroughly, then applied a thin layer of the silicone, then used a rolling pin to slowly roll on the pad. Added a bead around the edges of the pad to seal them in, and then placed it on a flat surface with a flat board over it and several rolls of filament on top to press it down. Left it to cure for a day. It's been going fine for about a year of daily use.
You can see pictures of it in the link in my signature.

@snoozer room temperature vulcanization is a mouthful.

@snoozer im gonna use a spare e3d v6.1 i think...the ones used on the original prusa...got a spare one hehe
After much thought and some more research, i decided to go 24v instead of mains (220v).
For both safety and the simplicity of everything.
The RSP-500-24 will do just fine, as i found that is used on the lulzbot taz 6wich used a silicone heated bed rated at 360w.
The heated bed will probably be the same as the taz 6.Difference in price from one way to the other is around 25€ and i much prefer paying a bit extra for the simplicity of the system.
Tks everyone for the input on the matter.

After much reading and a bunch of good an plausible advice I also give a silicone heater under a substantial aluminium plate a go. I stay with 230 AC, I am qualified electrician (in a former life) so no worries about mains. Did you order the V-Core including the printed parts ? the hotend mount is designed for a v6 I think. I have spend all last WE to make a Titan Aero mount, only done it in PLA with little infill as test. Still don't have the kit to put it on actually. I like to have it detachable and keep the belt tensioner attached. I split the mount. Intend to be able to manually change between hotends and also service it easy. Maybe able to use a laser as well.......... that's for future.

I did a rework of this mount, in Fusion 360: E3D V6 Hinged Extruder Bracket & Clamp for my little Monoprice Select v2. It's pretty kludgy so I didn't post my rework, but I have all the wires on plugs and can change the v6 clone on it in about 30 seconds. (Went with genuine v6 Gold for my CR-10S)
Kinda cool to have a hinge.
@pedromelim - Good luck with your project, keep us posted!
