I purchased the I3 M201 printer, I encountered the following problems while building the printer"
problem 1, the diameter of part #2 L470mm smooth rod is too big to fit into the holes of parts # M1 & M2
problem 2, I did not find part #58 Thermo-metry & heating wire. I did find wiring with a socket that has 2 red 2 blue and 2 black. that can fit into #59 (heatbed). the socket can only go into the heatbed one way only. But here is the problem, the instruction printed on the heatbed says pins 1 &2 should be + red, 3&4 should be blue 5&6 should be -black. The socket pin are reversed. now 1 &2 wire color are black and 5&6 are red. Do I need to follow the instruction on the heatbed? or the polarity is not critical.
Problem #3, step 21 (page 51) x belt driving wheel: Part #42 (holder) is too big to fit into the slot of part # M2. I have to file it down to fit in the slot.
Problem #4, Missing the brass fitting for part #60 extruder, In the video and in the pdf (page 59), the brass fitting are clearly shown

Problem #5, when mouting the extruder, there is a screw that tight the Z top mount (part #A8) to the frame obstruct mounting the extruder to the frame. I have to remove the screws.
Problem #6, mounting psu. In the instruction video, the red wires are connected to slots. 2 & 3. In the pdf (page #67), the red are connected to slots #1 & 2. which version is correct?
