I have made all the researches:

But I am still unable to craft the Chassis MK1:

I am running on logisticspipes-0.10.3.14, MC 1.12.2. (the 0.10.3.14 doesn't work on my server an exception occurs).

I cannot seem to reproduce that issue with the newest version:

Do you have any recipe altering mods installed? e.g. CraftTweaker. Also I don't quite get your last sentence. What LP version do you have now? 0.10.3.14 ? What exception is being thrown in the latest version? Can you show me the tooltip of the Logistics Programmer item? Does it say "Logistics Chassis Mk1" ?

Ok my mistake. I did not understand that I need to load the program into the programmer. Now it works!
