The bed will move on the Z axis with two 12mm linear rails and a 8mm lead screw on the rear and another two lead screws one on each side near the front. The bed heater will be pid controlled so I am not worried about it being overpowered. I can always reduce the on time if the bed temp spikes.by Dwarfer - Reprappers
Hi, thanks for the reply. I can probably go to 8mm thick plate. My print head can reach about 345x345mm so I could extend my build area slightly and go for a plate 350x350x8. I would then have a 25mm area all round the edge not directly heated and I suspect the mat heating element stops a few mm from the edge as well. I'm probably not going to need the extra build space but it's always nice toby Dwarfer - Reprappers
Hi everyone, I've just signed up and hoping someone can give me a bit of advice. I'm designing and building a printer from scratch and am wondering how thick my print bed should be. The bed will be 330x330 mm cast aluminium tool plate with a 300x300mm 750w silicone heat pad stuck underneath. I can get tool plate from 5mm thick and was thinking of going for 6mm as this should give me enough thickby Dwarfer - Reprappers
