⬢Are you left or right-handed? The printer should be already laying on its left side from the previous chapter. If you are a left-hander rotate it carefully on the opposite right side (see the picture). We are going to attach the upper CoreXY part and tighten the screws to interconnect both parts together. The instructions are the same, choose the side which suits you better for tightening the screws.
It is recommended to place a cardboard pad under the side of the base to protect the work bench and the frame from scratch.
⬢There's a hole in the extrusion that the pin has to fit into.
⬢Move the rear profile insert inside each extrusion of the CoreXY to the rear side of the assembly.
⬢Slide the remaining inserts approximately to the middle. Precise position will be addressed later.
⬢Rotate the CoreXY on its longer side and put it near the top of the four base extrusions.
⬢The rear profile inserts must be facing against the rear extrusions. Do not push the CoreXY all the way in until you are prompted.
⬢On the left side of the CoreXY, there are three M3nEs nuts in the extrusion. Slide the middle M3nEs nut behind the linear rail. Align its hole with the hole in the linear rail.
⬢On the right side of the CoreXY there are three M3nEs nuts in the extrusion. Slide the middle nut behind the linear rail. Align its hole with the hole in the linear rail.
Rotate the rear side of the printer towards you. Repeat the proces of inserting the M3nEs nuts, Earthing-connectors and M3x8rT screws described in the previous steps.
⬢Insert the M3nEs nut in the vertical extrusion on the left side. Roughly 6 cm from the bottom extrusion.
⬢Continue by inserting the M3nEs nut in the extrusion on the top side. Move it to roughly the initial one-third from left.
Make sure all the connectors are facing out from the printer as in the picture.
Do not tighten the screw firmly, we might need to adjust the position of the Earthing-connector in the extrusion later on. 4-5 turns are enough.
This step explains how to insert and lock the cover-clip. The exact position of each clip will be described in the upcoming steps.
Use any extrusion closest to you.
⬢Hold the clip so that its longer side is aligned vertically. Then insert the cover-clip into the extrusion.
⬢Once the clip is in the extrusion, rotate it 90 degrees. Both directions are fine, the clip is symmetrical
⬢Now, the cover-clip is secured.
Note that due to tolerances, the clip might not hold in place. This is OK, its main purpose is withstand being pulled/pushed and it will be secure in place using a screw.
In this step, temporarily cover the electronics. This is to protect the electronics during the installation of the tool heads in the following chapter. The electronics cover does not need to be tightened.
⬢Attach the XL buddy box cover to the screws on the electronics box. And slide it down to lock it on the screws.
⬢Well done! You just finished the CoreXY & Back assembly.
⬢Now, go to the next chapter 4. Heatbed & Side panels assembly.
