Before we start with partial disassembling of the printer, proceed with the following steps:
⬢Unload the filament from the extruder.
⬢Turn the printer off and unplug the power cable.
⬢Remove the steel sheet from the heatbed.
⬢Take off the filament spool from the spool holder and remove the spool holder from the printer.
⬢Carefully turn the printer on its side (on the PSU).
⬢Disconnect both LCD cables from the LCD board.
⬢Very carefully remove the LCD cables from the aluminum frame extrusion. Do not pull on the cable!
⬢Using the needle-nose pliers, cut the zip tie near the PSU. Be careful not to cut the cables!
⬢Follow the cable bundle up. Cut two zip ties securing the cable bundle over the LCD cables.
⬢Cut remaining zip ties on the cable bundle. Their number may vary at this location.
⬢Remove the LCD cables from the cable bundle.
⬢Put the printer back on its feet and leave the LCD cables free next to the printer.
Avoid placing the printer on LCD cables!
⬢Move the heatbed away from the LCD.
⬢Release all four screws holding the LCD in the front plate. Remove the LCD from the printer.
Put the LCD in a safe place for now. You'll need it again soon.
⬢Release two screws holding the PSU-cover and remove the cover from the PSU.
⬢Loosen two screws holding the PSU on the aluminum extrusion. Do not remove them completely! Keep them in place.
⬢Release two round head screws from the front side of the frame securing the PSU.
If one of the screws is hidden behind the X-end, manually rotate both threaded rods at the same time to move the X-axis up or down.
⬢Slightly lift the PSU until it can be completely released from the printer.
⬢Remove the PSU from the printer and place it behind the back of the printer on the piece of cloth, like in the picture.
You will need to slightly lift the printer to guide the cables out of the frame.
⬢Carefully turn the printer on the "electronics" side.
Avoid putting the printer on the LCD cables!
⬢For the following steps, please prepare:
⬢Zip tie (3x)
In the upcoming steps, please tighten all zip ties carefully, as you might pinch/break the cables.
⬢Locate the circular holes in the frame near the Z-axis right motor.
⬢Slide the zip tie through the circular holes in the frame to create a loop.
⬢Guide the motor cable in the zip tie and tighten it. Be careful not to over tighten the tie as it can cut the wires. Cut the remaining part.
⬢そのまま下方向に進み、別の結束バンドを使って次のループを作ります。
⬢Insert Y-axis motor cable to the current bundle.
⬢Push the cable gently in the zip tie and tighten it so it is snug and holding the wires. Be careful not to over tighten the tie as it can cut the wires . Cut the remaining part.
⬢Following the cables and secure the bundle with the zip tie in the next couple of holes.
⬢For the following steps, please prepare:
⬢Printer frame support (1x)
⬢M4x10r screw (2x) previously removed from the PSU
⬢Slide the printer frame support on the screws in the aluminum extrusions (instead of the PSU).
⬢Move the printer frame support to the frame.
⬢Secure the printer frame support to the frame with two M4x10r screws.
⬢Fully tighten the screws on the printer frame support.
⬢For the following steps, please prepare:
There are two textile sleeves in your kit with different lengths and diameters.
⬢Textile sleeve 8 x 350 mm (1x)
⬢Zip tie (2x)
⬢From the electronics, wrap the PSU cable (including the black&white power panic cable) in the textile sleeve.
⬢Leave 2-5 cm from the electronics uncovered. Secure the end of the sleeve with the zip tie.
⬢Wrap the entire length of the bundle and slightly twist the sleeve, not the cables.
⬢Secure the end of the sleeve with the zip tie.
⬢For the following steps, please prepare:
⬢Textile sleeve 13 x 400 mm (1x)
⬢Zip tie (2x)
⬢From the electronics, wrap the LCD cables in the textile sleeve.
⬢Wrap the entire length of the LCD cable bundle.
⬢Using the zip tie, create a loop through the circle holes in the frame around the motor cables and LCD cable bundle.
Do not forget to include the Z-axis left motor cable on the front side of the frame! See the detail.
⬢Leave 2-5 cm from the electronics uncovered. Secure the cable bundle with the zip tie. Do not over tighten the bundle! You may cut the cables.
⬢Merge the LCD cable bundle and the PSU cable bundle and secure them together with the zip tie.
Do not over tighten the zip tie! It can damage the cables.
The following procedure is intended for a single material printer. If you have a multi material printer, go to Disassembling the LCD.
⬢Release the M3x10 screw securing the FS-cover and keep it aside. We will need it again later on.
⬢Remove the FS-cover from the extruder.
⬢For the following steps, please prepare:
⬢New FS-cover (1x)
Note, that the new FS-cover differs from the old one for the MK3S+. It has a brass insert.
⬢M3x10 screw (1x) re-use the old one
⬢Fitting QSM-M5 (1x)
⬢Attach the new FS-cover on the extruder. See the correct orientation. The beveled side must be on the right (above the extruder-idler).
⬢Secure it with the M3x10 screw.
⬢Screw the fitting into the brass insert in the FS-cover. No need to use a side wrench.
⬢Remove the SD card from the LCD assembly.
⬢Remove the LCD knob and keep it for later use.
⬢Release two M3x10 screws securing the LCD screen.
⬢Slightly push the latch on the LCD cover and remove the LCD screen.
⬢Slide off the LCD supports from the LCD screen.
⬢For the following steps, please prepare:
⬢LCD-support-L-MK3S+ (1x)
⬢LCD-support-R-MK3S+ (1x)
⬢M3nS nut (2x)
⬢M3x10 screw (2x) previously removed
⬢LCD-cover (1x) old part
⬢LCD screen (1x) old part
⬢LCD-knob (1x) old part
⬢Insert all the way the M3nS nut into each LCD-support.
During handling, be careful that the nuts do not fall out of the parts.
⬢Slide the LCD-support-L from the left side of the LCD board (side with the SD card slot) to approximately the same position as in the picture.
⬢Slide the LCD-support-R from the right side to approximately the same position as in the picture.
⬢Insert the LCD screen with the supports all the way in the LCD-cover. The LCD controller must click under support in the center of the LCD-cover.
⬢Adjust the position of the supports if needed. It must fit in the cutouts.
⬢Secure the LCD with two M3x10 screws.
⬢Attach the LCD-knob on the encoder.
Knob mounting orientation doesn't matter.
⬢That was easy, wasn't it? Reward yourself and replenish your energy for the next chapter.
⬢Eat the second row of the gummy bears. Leave the others!
⬢Carefully place the PSU on the heatbed. Use a piece of cloth as protection.
⬢Well done, the printer is prepared.
Place the printer aside for some time, we will need it later on.
⬢Now, let's go to the next chapter: 3. Assembling the enclosure
