I am using version 18.47
The following message when loading the mod:

Fehler beim Laden des Mods: Technology micro-furnace:
Non-contiguos levels, followed by 1

Non-contiguos levels:1, followed by 1

sorry..

Hm, do you have any other mods that affect furnaces?

Yes, the following mods:
Advanced Furnaces / from Autor badway / Version 0.0.8
Micro Furnace / from Autor WipMod / Version 1.0.4

The first is a larger (4x4) high speed oven
The second a 1x1 oven with high speed.
... Could that be the problem?

Hm, it looks like the issue is with this mod and Micro Furnace, but this is a new error I haven't seen in any of my mods before. I wonder if it might just be a technology overlap... since they're both called micro furnaces, they might actually have the same internal name.

EDIT: Ah, yup, they totally use the same name for micro-furnace-1. Although... now that I think about it, there shouldn't be any reason to run both of these mods, since Micro Machines already has micro furnaces built in. Hm, oh they're endgame upgrades. I think I can make this work actually.

Alright, compatibility should be fixed as of v1.0.2

The micro furnaces introduced by this mod will be disabled in favor of the ones from WipMod's Micro Furnaces, since they're so much more powerful (and probably more balanced)

Hi Kryzeth,
You are an artist.
Please excuse the inconveniences.
Thank you so much for the fix.
I'm really looking forward to trying out your mod.

I have just tested the Micro Assembler and Micro Beacon.
Runs absolutely flawlessly. Loading is now without problems.
I just wanted to say thank you again for the great service.

Sweet, very glad to hear you're enjoying the mod! Many thanks for the kind words :D
