Nicholas, thank you for posting this. I downloaded the files and took a quick look in Inventor. Would you also post the iam (assembly) of the complete machine?by 3dbotic - Delta Machines
From what we have seen, you can get 12-14 amps going to the heat bed (assuming 12v) We don't recommend it but, you can run a bypass wire and heatsink the MOSFET, if you can find the room to get a sink on there. We use straight header style connectors. If your Sang board uses the 90 degree style, you might be able to put a sink on there. Also, you will need heavier gauge wires from the Molex cby 3dbotic - General
That's interesting because its using arms like a 'traditional' delta assembly robot instead of a Rostock linear bearing style delta. Does appear to have some slop in the actuators/servos.by 3dbotic - Delta Machines
We use the Sanguinololu 1.3b board with our kits, the Mk2 heat bed, and a single 360 watt power supply (non-ATX) to power everything. We power the board with 12 volts from the power supply. I recommend that you use a relay to control the current being sent to the Mk2 heatbed. You are right, the Sanguinololu cannot handle that much current. We also recommend adding a fuse between the relay anby 3dbotic - General
