I cannot promise anything about compatibility with overhaul mods, because they tend to not following general rule about usage of data phases. That would be massive time sink to make mod-specific compatibility code with them. (An example just within this month, I had spent hours to crawl through several Angel's mods in an attempt to find the cause. It turns out a single misspelling in one Angel mod causing that.)
Therefore, I will only make "generic" mod compatibility code fix from now on.
But before declaring it's a code problem, let's see if it is only just option settings problem first:
Does the electrics assembling machine from Bob's mods also work? I was sure I set the filter right in the settings, but I don't see the scaled recipes. This machine also restricts crafting to only circuits, maybe that's affecting it?
Every vanilla machines already have crafting category restrictions. Like chemical plants use only "chemistry" category, centrifuge use only "centrifuging" category. The machine you mentioned is just using another category, in principle. No specific code in my mod, so should be handled in principle.
Try set "Usable recipe set" option with "Both scaled & original sets", this will help finding if the filter is set right.
Even better, posting screenshots can help:
1/ On mod options screen. So I can see if you have set correct values.
2-3/ On technology screen, where the recipes (electronic circuits, I suppose?) are shown. Supposed to have both original & scaled recipe icon on the technology effects list. Hover on both of them and make screenshots.
Maybe also the machine names that you want it to work, can be seen in "F6" debug mode.
