What I understand is say I have a heated bed which is having a fixed resistance due to its physical configuration/setup etc. Half the current or Double the current ?.Let me verify my understanding and clarify my basic - I may be grossly wrong here. Large delta printer, E3D tool changer, Robotdigg SCARA printer, Crane Quad and Ormerodĭisclosure: I design Duet electronics and work on RepRapFirmware. This is especially significant on delta printers (but you also need a 32-bit controller to get high speeds on a delta).įor the typical budget Cartesian printer with 200mm square bed, 24V power doesn't offer any significant advantages. ![]() It allows the stepper drivers to move the stepper motors faster, especially if they are 0.9deg motors. ![]() An alternative is to use an AC mains voltage bed heater.Ģ. This is an advantage if you have a large or powerful bed heater. It halves the current you need for the heated bed compared to using 12V power. reconfiguring the firmware without having to rebuild and upload it, web interface, 32-bit processing power, etc.).ġ. But if you are spending a serious amount of money building a large or fast printer, then I suggest you buy better electronics that is already 24V-capable and may offer additional advantages (e.g. If you are on a tight budget and you have some reason why you need to use 24V power, then go ahead and upgrade it to 24V. Arduino/RAMPS + stepsticks is budget electronics - probable the lowest-cost electronics you can get, which is why it is so popular.
