Gaou thanks for the tip! I will have a look, but "custom design" together with "single unit production" usually equals to "high prices". In any case, maybe there is something already done by them in bigger quantities and available on ebay as you mention. It's worth looking. Thanks again!by Otura - Duet
I understand now. It's not easy to find a 300x300 heatbed rated 360W (most of them don't include any details on resistance, amperage or wattage, only voltage). So, I will proceed as follows: 1. I will buy that one. 2. With a multimeter I will measure the real resistance, and will calculate the wattage and the amperage at 24V. 3. If amperage is below 18A, I will run it through the DuetWifi direcby Otura - Duet
Thanks a lot! So, can I regulate the amount of amps that I send to the heatbed from the duet? It's that done through the firmware? I understand that from your sentence "I suggest 0.4W per sq cm", where it looks like I can choose that amount somehow. On the other hand I would prefer not to use SSR, to keep the electronic as simple as possible. Finally, my printing bed will move on the Y axis, sby Otura - Duet
Hi again, I've been reading some specs on the heatbed (MK3 300*300 Aluminium). It seems that it has a resistance of 5-5.5Ohms. That, at 24V, results in between 105W and 115W. Against the 480 that I took into account for my former calculations. I am confused now (yes, more). Should I take into account the 115W or the 480W. If the answer is 115W that would result in a total wattage requirement oby Otura - Duet
Hello everybody. I'm writing my first post and I'm asking for help. I know it does not seem too "contributive", but I'm pre-new (yes, that's even before being new) into the 3D printer world and cannot help much nowadays. I hope I will be able to contribute in the short-term future. Now, I'm designing a custom 3D printer (300x300x300) which with the requirement that it should be foldable and fitby Otura - Duet
