[Min KSP 1.12.X] Sandcastle: 3D printing for parts and vessels

[Embries]

Is there a manual or tutorial for this mod?  Preferably not a Youtube video.  I get the intent, But I am struggling to find a step by step what to do.

Printshop idling issue

Hey, I've got the same issue as Findlay (idling printshop), and I believe the source of the issue to be from reloading the craft. This is quite annoying, as it prevents me from using the mod's functions. The common fixes I've tried have all failed, even using cheats to bring a new printshop to Minmus only allowed it to work until the next reload.

How do I remedy this? Will this get patched?

This is a tough one, do you have steps to reproduce it?

For some reason the smelters demand I construct a dyson sphere. I've checked the configs and they look normal enough, I have ZERO clue why they draw this much power when making metal. It's not just in the VAB, they suck that much power in actual use.

The EC values come from ExtraplanetaryLaunchpads/Resources/ECSmelter.cfg. There's an explanation in the config as to why it uses the settings it does.

There's also a patch at WildBlueIndustries/Sandcastle/Patches/ECSmelterClassic.cfg that tries to adjust the value, but it just adds an extra config node rather than modifying the existing one. 

Modifying the patch as follows or adding the following patch to your own patch folder would apply the intended settings:

{
	// Smelter uses electricity for heating instead of LFO combustion.  Liquid
	// fuel is mixed with metal ore to remove O3. The resulting reaction
	// produces metal (Fe) along with water (H20) and carbon dioxide (C02).
	//
	// From existing EL recipes:
	//
	// LiquidFuel is assumed to be RP-1 which is further assumed to be C12H16
	// and thus is 160.25544g/mol
	//
	// MetalOre is assumed to be hematite (Fe2O3) which is 159.6882g/mol
	//
	// Metal is Iron (Fe) 55.845g/mol
	// Carbon Dioxide (CO2) 44.0095g/mol
	// Water (H2O) 18.01528g/mol.
	//
	// This gives the following reaction:
	//   32Fe203 + 3C12H16 = 64FE + 24H20 + 36C02
	//
	// With the following masses:
	//
	// Input:
	//     Fe2O3 = 5110.022g
	//     C12H16 = 480.7663
	//
	// Output:
	//     FE  = 3574.08g
	//     H2O = 432.3667g
	//     CO2 = 1584.342g
	//
	// Total Mass (in & out) = 5590.789 (Used for EC rate)
	//
	// From wikipedia Electric Arc Furnace uses 440 kWh per ton per hour
	//   440kWh = (440,000w/hour)/(1,000,000g/hour) = 0.44w/g
	//
	//  1 EC assumed to be 1 watt, NFE uses 1 EC/s = 1000w. But this seems to
	//  to be a really low power consumption.
	//
	//   440kw/hour = 122.222 watt/s (use for scaling rate in part definition)
	//   Use Rate in EL_Converter definition of part to fine tune.

Thanks, this fixed it!
