corrected, thank you

That's about right.

Hi @maclemon , The colour of the arms did change to black as we think suits the machine looks better, of course, this is personal preference. The website pictures show the real kit colours while the guide still shows the old color scheme, the guide pictures need to be updated to match the real parts, as it's only an aesthetic change, we are prioritizing other aspects of the documentation. The first production kits had all the heat inserts pre-installed, this was a nice surprise for the early bird users. Nowadays the kit doesn't come with pre-installed heat inserts anymore, the guide has all the required steps to clearly instruct you where those should be installed. Thank you for your feedback!

Sorry, not sure I understood your question, could you explain further?

The list has been corrected, thank you for your feedback!

The picture is based on looking at the printer from the rear, using the standard electronics panel found here.

Hi! All 4028 fans supplied by RatRig have 4 wires, the guide only shows 3 to avoid confusion since you only need to connect 3 cables, 12V GND and PWM. The Nidec fans use Red for 12V, Black for GND and Blue for PWM as mentioned on the product page. It should be present on the guide step like the Delta and Sanyo, Thanks for your feedback it will be fixed right away! Enjoy the rest of your build!

Exactly, in some cases, the space between the XY Joiners and the front plates is so small that it needs to be "measured" with your fingers by feeling the play as you described. It's not as big of a problem as a visible gap, but still worth tunning for a more advanced user! Thank you for your feedback.

Thank you for your feedback!

On Delta fans the blue wire is the PWM wire, The yellow wire is for RPM monitoring, by default it's unused.
