@bananas:

Solved!

I had changed the original H-Bar ends from a 4 wheel version to a 3 wheel version when building the D-Bot. The 3 wheel version moved well and there was no play at all. What I suspect happened was the H-Bar was twisting or flexing slightly as the belts applied force at either end.

Going back to the 4 wheel version solved the problem.

Thanks everyone for your help.

Can I ask which 3 wheel z carriage mod you were using?

Now I'm a little confused. Should selecting a temperature either in the active or standby drop-downs turn the heater on and heat to the selected temperature? Or have I misunderstood? The bed turns on and heats to the selected temperature in the active temperature dropdown.
Thanks
