On first trying to connect to the controller web interface we got the error “Your Duet rejected the HTTP request: page not found Check that the SD card is mounted and has the correct files in its /www folder”. There was an SD card supplied separately which I don’t remember seeing any instructions to install into the controller board. We plugged the card in and that fixed the issue.

Should be File -> New Terminal rather than Open Terminal

The controller case is intended to be installed by a double-jointed contortionist with tiny steel like fingers who can route large numbers of cables through small holes neatly and tidily. I’m not sure why devices like this with controller cases always try to use the smallest case size which limits the size of the cable holes. I had similar problems building a Prusa 3D printer. If the case were a bit bigger with a bigger cable hole the job would have been a lot easier and would have looked much neater.

Out limit switch-1 cable had a brown tag rather than orange.

If you have a Touch Probe that wire needs to be routed into the controller box in this step.

Don’t laugh…well I suppose you can if you want! If like us, you reach this point and think “the diagram shows the limit switch mounted above a stepper motor and our stepper motors are at the other end of the machine”, then your first reaction might be “Oh no, we’ve mounted the X gantry back to front”. You might then sit trying figure out how to reverse the gantry and start to lose the will to live at the number of bolts, etc you need to disassemble and reassemble whilst keeping the whole assembly square.

Then we sat a bit longer and figured out what we’d actually done wrong was to fit the stepper motors on the front of the machine rather than the back. That proved to be a much simpler thing to correct.

What’s the learning point? Know your front from your back! Actually we also wondered whether the kit could include a sheet of front/back/left/right stickers to be stuck on temporarily during the build to help keep track of what’s where?

To get the single nut tightened we had to take two spacers off the stepper motor.

This applies through all the guides…it would be useful to start each step with the list of parts needed in the step. We find we have to read the step to find all the parts we need, then read again to see what we need to do now that we can see what the parts look like, then read again when we do the necessary tasks.

This does require a bit of force and my assistant found his thumbs hurting ;-) We found that if we threaded a bearing/wheel/shim/bearing along an allen key that centered them nicely and then we used another allen key at right angles to the first one to pull the bearings into place. When done this way the shim seemed to be solidly fixed between the two bearings and my assistant’s thumbs hurt less!
