So when it comes to the input material. Should it go in as buds or should I shred it? What are the benefits to whatever is best and what is the downside to the other?
into a wiper?
I don’t think you’re on the same page as the rest of us…
how you produce the input for your wiper can certainly make a difference in how you need to run it, but that also includes the solvent of choice, and you have made no mention of how you’re extracting.
size reduction does help with extraction efficiency. opening cells (eg using a whirling blade) degrades quality (brings along more unwanted). your target is extra-cellular, so opening cells is counter productive.
see eg: Multi-photon microscopic images of various types of cannabis trichomes
see maybe: Beating the "shred" horse

I want a wiper that takes biomass… sounds like it would be one hell of a skid; biomass in one side, money out the other

can anyone weigh in on the topic of condenser temp for reverse cuts? Is it true/possible that running too cold can codistill noids (10-20C) during a cut? would more standard temps be better, if something was lighter would it pass through to the cold trap if rejected by the condenser? Or is it possible that undesirables stay in the residue due to this?
On the topic of grinding, I usually say if they can pack the target weight without grinding that’s preferable, but if the nugs don’t allow it then gotta hit it with the weedwhacker. To me, I think there is a trade off both with time, material potentially lost grinding as well as slightly more cleanup.
I don’t think that’s true unless you’re also increasing separator temperature. If the separator temperature is low enough that cannabinoids won’t vaporize, changing the condenser temperature doesn’t have an impact. You can in theory run your condenser as cold as you want, provided your terps don’t solidify on the condensing coil or clog your discharge pump

Agree with @PolyC. Just be mindful of your vac levels, too

If i understand your question correctly then no you should not see co-condensation of cannabinoids if your evaporator is below their boiling point at whatever vacuum depth the systems at.
The internal condenser temp will have a limited effect on the evaporator; mainly in that an inefficient IC temp can raise system pressure(mainly if its too hot) ultimately reducing system efficiency as a whole, but other then that it will have very little effect on the evaporator.
And yes the internal condenser can be used to reject specific boiling point ranges for fractionation which would force lower bp compounds to condense on the cold traps.
It comes down the enthalpy of vaporization/condensation; and essentially what that means is if a compound takes a certain amount of energy(heat) to make it evaporate and phase change; then a proportional amount of energy(heat) must be conversely removed to make it condense.
If your seeing cannabinoids in your condenser in a lower temp pass; it may be due to splash over, this is especially common if your material hasn’t been decarbed before running it. System design can play a role in this; mainly if the gap between the evaporator wall and IC are especially short like in smaller glass rigs.

Yes, I have seen noids in the cut while running below their bp so I was thinking it was some sort of entrainment. But thank you guys for the clarification.
Are you decarbing your oil first? Make sure it is decarbed before wiped film molecular distillation.
How is the oil extracted?
Your vacuum levels seem a little off to me. For your terp strip your vacuum level should be about 0.2-0.4 torr, so you are going a little deeper than necessary there. Adjust your feed speed based on your vac level.
On your second pass to get your product, distill at the temps you are using, but make sure vac depth is 0.03 torr or less. If your vac is really getting down to 0.001 torr, you might need to lower your evap temp to 155-160C.
Is your oil pre-heated as it feeds into evaporator? Typically it’s preheated to around 100C.
Hope that helps!

Have another silly question I’m used to useing spd. And now useing a wiper how much tails do you see people typically get off a 10 kilo batch think some of my tails are getting in to my main body and giving the disty a bad taste
It should be quite similar. I typically see a ~25% mass reduction from post-decarb to distillate (including transfer loss). If anything, take samples after each pass and see where the funky flavors comes in. If all of them taste funky it may be a procedural/parameter/equipment issue.
Thank you I’ll do that ya I’m seeing random jars go dark after heating them up in a beaker it starts to go dark only with certain Terps and has a rubber taste
I don’t get the same type of tails that I used to get with short path. If you’re talking about the residue after main body pass, I usually aim for a 1:7 ratio for residue:main body. If your disty is getting a bad taste, then you may need a clean cycle before running main body pass. I bypass this and run MB pass after volatile pass, get a small portion of heads to clean out the distillate pump (around 25g), test for smells and texture, then collect MB in a clean jar.
