Thanks guys, I probably should have mentioned up top that my printer is quite small: 200 x 200 x 6/8(still deciding, perhaps someone could weigh in - cost is almost identical) mm bed so a 200 W heater is more than enough for me which makes a DC bed way more feasible. I think AC is the only way to go if your plate is any bigger than mine but I really sit on the boundary. Are the non genuine siliby Forum-Layman - General
Quoteetfrench Why does AC wiring need to be in a conduit? Billions of AC appliances don't use conduit. In the UK at least all cabling must be double insulated (that's why the individual strands are encased within a black (usually) plastic insulation on kettle leads) so I would be surprised if you can find something with just single insulated and has exposed mains wires (essentially you should nby Forum-Layman - General
QuoteVDX ... for AC -- instead of wiring to mains, you can use tansformers with "harmless" voltage levels - used to heat my fist bed with a "12V-transformer" at roughly 16 Volts AC I think that probably adds a little more complication!by Forum-Layman - General
I have been going back and forth on a new printer build I'm working on about the bed heater and whether I should go for a 200W 24V heater pad from keenovo or a 240V 400/500W heater pad from keenovo. So I've come here to seek some wisdom! As I see it the AC pad obviously heats faster but is also much higher risk and trickier to install. Ive read about the UMMD bed wiring so would probably emulateby Forum-Layman - General
The new design looks better - I like it. Seems that you still have a lot of parts to make though so good luck!by Forum-Layman - General
Quoteruyvieira QuoteEd3D Is there any negative to using F695 idlers on the toothed side of the belt? Im concerned that it will damage the teeth or is it not an issue? People think it will give you extra-ripply vertical surfaces and flatten your belt and or shred it, but in practice it's fine, lots of commercial printers do that (Lulzbot Taz, Makergear M2 and most of the Creality 3d printers) Yoby Forum-Layman - Mechanics
I never thought about buying a used printer online to retrofit - it's a neat idea i might have to have a look on ebay..... look what you've done now!by Forum-Layman - General
QuotePaulgwat Z height isn’t hugely important to me, but the ability to create a flat surface that is distortion free is. I think this is where you're going to struggle most. Big and flat usually means expensive too, doubly so when you want it to stay flat when heated. Unfortunately I don't think what you're after exists at your budget so you may need to scale back the size or scale up the budby Forum-Layman - General
