This may have solved my problem....
Just done the first print of a 20mm cube leaving the temperatures as my normal.
The cube came free of the plate very easily after the bed reached 53 degree C. So first result v'good
The one main difference is the thickness of the ABS layer left by the 'puck' ( in my case an old 20mm cube ) there is a much thicker layer that peels away from the bed plate.

Yes I print at a bed temp of 118 degrees C and don't have distortion problems when the bed was cooler. I also don't use fans to cool the part as it's being printed. The more consistant the temperature the better.
My parts come free ok once the bed has cooled, as you say below 50 degrees C. I have wondered if I had damaged the surface with scratches from a stanly blade I use to clean off the ex

Tried to attach this photo to my previous posting but fialed, smaller file now.
This is not something on the surface, but the surface has been pulled away.

I am having the opposite problem !
My ABS is sticking too well, the last print pulled away a thin section from the surface and has remained stuck to the bottom of the printed part.
This has also happened once befor when I was using 3mm window glass, I changed to Borosilica glass thinking that it window glass was too brittle but the problem has not been solved.
My ABS juice is acetone and some A

I built a delta earlier this year and found that the most important point is to make sure the angle of the push rods from the ball joint centres is exactly 60 degrees to the vertical slides.
Using Marlin as control sw :- got the angle wrong on my first attempt (58.62 degrees), I modified the angle value in config.h expecting the calculations to then be corrected.
This approach did NOT work so a

Yes I did solve the problem.
There is a later u8g library that solved the compile issues, it's u8glib_arduino_ v1.1.15 zip found going to the u8g web page best.
I found that adding a library from arduino was a sure way of unpacking it in the correct directory. Read the attached instructions in the zip file.
Open up arduino and go to sketch menue, then import library having already unpacked i

I also have a problem with the LCD not working. Without any LCD options made in the config file the board uploads ok and it responds in 'printer interface' correctly.
No documentation at all about the LCD screen ; when the //#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER is enabled the Arduino compiler reports errors in the u8glib files. (u8glib is in the libraries folder)
The screen is
