Hi guys,
I built the LM317T example regulator here, page 7, bottom right.
https://www.electro-tech-online.com/custompdfs/2011/01/LM317T-ST.pdf
Cin - 100nf ceramic
D1/D2 - 1N4004
R1 - 240 ohm, 1/4 watt
R2 - 4k7 pot
Cadj - 10nf/50v
Co - 2200uf/50v
My input is switched clean 24v DC.
My problem is R1 gets damn hot when the pot is turned to closing on 0. Also, with a multimeter attached to the vout, I'm getting 23.5v +-, even when adjusting the pots very slowly.
Here is a pic of my project, there is no track breaking.

I must be doing something wrong?
