thank you so much for replying so fast!
Concerning 2) I have these settings set as you described and as for 3) and 4) I am using a M5 rod which I have lubricated.
You were spot-on with the 6) Vref setting and the 1) microstepping - I had set the microstepping to 1/8 and the Vref was at 0.05V. I changed the microstepping to 1/4 and set the Vref to 0.12V, which did the trick. I completeley forgot that that the driver is powering two motors and therefore needs to pass on a higher voltage! Thank you very much for pointing this out!
At the moment I have the regular nickel plated iron bolts - I will try to replace them with Nylon nuts at some point!
I have uploaded some photos of my build, which now runs smoothly and a tad bit quicker thanks to your advice.
A really great little printer!
