I’m really struggling here. What does click-over mean? Does it mean the stepper shaft rotates? How can it if it’s locked? I’ve managed to pull the lead screw out of the tensioner more than once now. No idea how tight those screws should be. I don’t want to over tighten and wreck the hexes. Will see if there’s a video out there on this.

Wouldn’t take much effort to move them over the mainboard. That said, perhaps they’ve done a CFM analysis and this is best? If not, is the design available so we can modify the case lid?

After rolling forward a couple more steps it didn’t look like I would ever be able to get the emergency stop connectors into the power inputs, so I ended up taking out three of the screws (leaving just the top right) which gave plenty of movement to be able to get them in neatly.

There’s ample sleeving. Recommend trimming the frayed ends and using a lighter to sear the ends as this will reduce any fraying while you’re fiddling.

Thanks to the comments here I decided rather than hot glue to install a small piece of matchstick in the channel, just at the point where the cable tie us, thus ensuring the cable tie is not only keeping the wire in the same area, but also holding it in place. This could be incorporated into the design of the chain mount rather than having to use a piece of wood.

I gathered all the cables together so that had three white connectors and the black and red cable end points (essentially everything that will go into the Duet) and pushed them through en-masse. The collection seems to hold together well and I got 99% of the way before I had to just fish a couple through, once through I pulled them through some distance.

Once I got to this stage of the build I had no idea which extrusion was which (i.e. A, E) as I’ve removed the labels. Might be worth adding a callout somewhere not to remove the labels until the end? Either that or name them in the diagrams.

My machine is a 750x1000. C extrusions are 745 in length. I calculated, from the given 80mm to the first A-extrusion-construction, that the distance between the other end of the first A-construction to the next should be 90mm. I repeated this from the other end. This resulted in an 85mm gap in the centre. I’ll stick with this, but was expecting an 89mm gap. As the measure was the same at each end, it looks like I made a mistake somewhere.

At the final step I loosely tightened the grub screw in order to rotate the clamping bolt into position. Then finally finger-tightened the grub screw after the clamping bolt.

With the motor in your left hand, and the shaft pointing right, orient the motor so the cables come out of the bottom, then twisting the shaft so that the flat side of the shaft is facing you. This will make it simpler when it comes to tightening the grub screw.
