Fokoos Odin-5 F3 works great out of box, but extruder tension is tight for TPU.

It is possible to add an adjustment screw, small plate, and lighter spring for adjustable tension. Idler frame ia already tapped for M4 screw.

Original spring looks like a yellow bed spring but much smaller. It measures 15.7mm L, 7.7mm OD, compressed force of 2,200g.  
I made spring using 0.9mm music wire. It has compression force of about 1000g.  
My plan is to change out for TPU, as needed. It only takes 4 screws and a couple minutes.

It was all fun, it took longer to write post. To save time, having adjustment is not necessary, just a lighter spring, that would save a few minutes. I researched off the shelf springs at Mc Master Carr, #8969T751. It is slightly stronger, with 1mm wire instead of 0.9mm. I have not ordered yet, waiting to place a larger order, to help reduce shipping cost.
