@reckham I have a set of 360mm for sale with ball stud ends, pm me if interested

Previous P value was that has worked ok for the last 2 years was 5 and the new one that now works ok is 25

Yes, that's how I am using mine, very easy to use this way

Have you set max temp up? up
M305 P0 T100000 B4607 C8.950070e-8 R4700 ; BED : Set thermistor + ADC parameters for heater 0

@dgrat I have also been using mine for the last few years as shown in picture two with no issues at all.
