Parallel L298N Driver circuit help - Electronic Circuits Projects Diagrams Free

Hello all. New to this board.

I am in the process of fabricating a 'parallel L298N' driver board which uses the L297 controller. I have built and tested a single L297/L298N 3-axis driver board and it works perfectly. Requiring more current capacity, I have tried to copy the single and twin the L298N and have taken care to parallel channel 1 with 4 and channel 2 with 3. For some reason the parallel board doesn't work and I have almost exhausted my trouble shooting with it. I am nearing the edge.
I was hoping someone has tried this already and might share some insight and experiences with doing it.
Any help would be appreciated.
Sid
