Octoprint and touchscreen

I'm trying to install a generic touchscreen on raspberry pi. If I use the raspbian installed on sd card and install the screen using the following

sudo rm -rf LCD-show
git clone GitHub - goodtft/LCD-show: 2.4" 2.8"3.2" 3.5" 5.0" 7.0" TFT LCD driver for the Raspberry PI 3B+/A/A+/B/B+/PI2/ PI3/ZERO/ZERO W
chmod -R 755 LCD-show
cd LCD-show/

The output changes to Lcd display no problem.

If I then install octoprint to sd card and use the above it doesn't show any output to LCD

Using Raspberry pi 3b

Am I missing something!

I can be much direct help but I followed this guide and it worked a treat.
