This is my second 3d printer and in principle I am happy with the machine. My other printer is an M200 Zortrax (Beautiful prints everytime)
Once you have wifi connection sorted (Gold medal if you do) I cannot emphasise enough just how important manipulating the black Printer cable is. you have to bend it like your life depends on it. I will say this much THE CABLE IS POORLY SPECIFIED. it is super important to mark the cable clearly and make sure you insert them with a polarity in mind.
the cable will plug in either way around. it will only work and pass the test if the cable is fitted correctly and ultimately flexible. I will be fixing a weight to my cable towards the top as it is getting caught on the back linear motor near the top. It makes a very rough noise.
The milky white HDPE Filament sheath also needs to be manipulated somewhat too. Be very careful not to put any kinks in it.
The oil needs to be smothered on all the moving parts not just the foam pads. it will take almost 1/8 to 1/4 and function ok.
I also highly recommend WHEN THE MACHINE IS OFF (or not in print mode) to move the linear motors up and down many times to get the oil well and truly worked in. There will be some residue at the bottom but this is entirely normal.
I have experimented with different release versions but am yet to get my printer to bind successfully once again since initial update.
I hope that this helps if a little bit long winded.
