1. He mentioned grease – higher current SSRs are sweat soldered to the base plate, they don’t use thermal grease.
The farther I need to travel to get to you, the more time is taken out of my day—and I’ll factor that into your bill. Finding someone closer to your neighborhood might be able to charge you less.
If you do not know the exact value of each cost, you could enter an estimated percentage based on the cost of goods.
They’ve lifted 200kg so far, and it looks like a pretty cool addition to a shop already packed with other builds, like their MOT spot welder and a propane tank sandblaster.
Simple, do you know how expensive it would be to change from 120v to 240v? It would be an insane amount and there would be virtually no benefit.
Europe is a real patchwork of degrees of sketchy. German wiring standards are very high indeed, at least in the semi-industrial places (laboratories, hospitals) I worked. The real Schuko plug/socket design is quite nice and safe, and hard to find *not* implemented correctly in Germany. Other countries, not so much. And don’t get me started on English and South African wiring and plugs.
I also own an electric kiln designed to heat and temper glass so a page can be taken from that design. I haven’t made the effort to investigate the heating elements as of yet.
No, because they are opposite phase. In this setup the neutral wire doesn’t carry any current, so the same 15 amps goes through both hot wires.
Of course a safe mains powered heater is possible, but you need a double insulated cable (which is stiffer and heavier) and a reliable strain relief for it. You have to permanently bond the heater PCB to the glass print bed with silicone. You need a fuse and a thermal cut out (thermal fuse) for fire safety, because the available power in the mains circuit is much higher.
Interesting idea. You don’t need a 3D printer for this though. Conductive strips or simple wire should work fine.
After checking to make sure the outlets are wired correctly, a 220v light bulb with light up across the two hots if they are opposite phase and not if they are the same phase.
