Update update. Thanks to advice from you guys i managed to successfully print the nut and bolt test pieces. They're not 100% perfect but they're a good starting point. As per your advice I slowed print speed for the first layer to 15mm from 20 and upped the bed temp to 70 degrees. The filament I'm using suggests 40-55 degrees for the bed so I'm unsure why i needed to goto 70 to make it work.
Now for a few questions.
If I level my bed with a 0.1mm feeler gauge does that mean I have to set z offset to -0.1?
Am I correct that the printer itself contains no settings at all and all relevant values are contained in the gcode the slicer generates?
Should I manually heat up the bed and nozzle first or is it OK to just go power on then straight to print from tf card?
