7. Y-carriage & Heatbed assembly
⬢For the following step please prepare:
⬢Heatbed MK52 24V (1x)
⬢Heatbed cable red (1x)
⬢Heatbed cable black (1x)
⬢M3x10 screw (2x)
⬢M3w washer (2x)
⬢M3nN nut (2x)
⬢IT IS IMPORTANT to connect the power cable correctly. Before you start the assembly have a look at the pins. The one on the left with "GND" sign must be connected to the BLACK WIRE.
⬢Take both Heatbed cables. Note the label on each cable. For the following steps, prepare the ends of the cables without the label.
⬢Place the black wire above the pin with "GND" sign. Use the end of the cable that is not labeled with QR code. The QR code must be at the other end.
⬢Place the M3w washer above the round cable connector.
⬢Press the M3x10 screw through all parts.
⬢Hold the screw and carefully turn the heatbed upside down.
⬢Attach the M3nN nut onto the M3x10 screw and tighten it slightly.
⬢Turn the heatbed back around. Using the universal wrench and the Allen key, tighten up the screw. We will adjust the cable position later on, therefore do not tighten the screw too firmly yet.
⬢Repeat this procedure for the second (Red / + / VCC) wire. Use the end of the cable that is not labeled with QR code. The QR code must be at the other end.
Before proceeding further, please check again that:
⬢BLACK wire must be connected to the "GND"
⬢RED wire must be connected to the "VCC"
⬢The cable cover, which will be applied later requires the connectors to be slightly inclined towards each other. Press them gently, but leave a gap between them.
Now, tighten both screws firmly using the Allen key and the wrench. Maintain the position of the connectors while tightening.
⬢For the following steps, please prepare:
⬢Nylon 2x380 mm (1x)
⬢heatbed-cable-cover-bottom
⬢heatbed-cable-cover-top
⬢M3x10 screw (3x)
⬢M3n nut (3x)
⬢Textile sleeve 5x350 (1x)
⬢Insert three M3n nuts into the shaped openings in the heatbed-cable-cover-bottom.
Use the screw pulling technique.
⬢Place the heatbed-cable-cover-bottom like in the picture. Push the heatbed thermistor cable through the heatbed-cable-cover-bottom.
⬢Insert the nylon filament into the hole in the heatbed-cable-cover-bottom. Don't let the nylon filament stick out too much on the other side. It should not protrude more than 2 millimeters.
When inserting the nylon filament, ensure that the filament does not damage the thermistor cables under the printed part.
⬢Bend the nylon filament slightly toward the cables. Be sure to maintain the correct curve orientation, as shown in the second and third pictures.
⬢Orient the curve of the filament as shown in the third picture.
⬢Slide the cable-cover-bottom under the heatbed cable connectors (M3nN nuts). See the correct orientation in the picture.
⬢Secure the cover with the M3x10 screw from the top. Tighten the screw firmly.
Make sure the nylon filament is still bent upward as in the previous step.
⬢Wrap the end of the cable bundle together with the nylon filament in the textile sleeve. Slide the sleeve as far towards the heatbed as possible.
⬢Attach the heatbed-cable-cover-top onto the junction and secure it with two M3x10 screws.
⬢On the bottom side, leave a slack on the thermistor cable for one finger to be pushed through.
⬢Make sure there is no big gap between both covers.
⬢Finish wrapping the cable bundle in the textile sleeve. And twist the sleeve, not the cables.
⬢The Y-carriage has two versions, depending on which MK3 printer model you have. Each version requires a different assembly procedure. Use the picture to identify your version and follow the corresponding instructions:
⬢
NEW version: there are three pockets (recesses) for bearings in the Y-carriage. If you have this variation of the part, go to step Y-carriage: parts preparation (new).
⬢OLD version: there are three cutouts for bearings in the Y-carriage. If you have this version, continue to the next step.
⬢LM8UU bearing (3x)
The bearings come pre-lubricated from our factory and do not require additional lubrication upon initial use.
⬢Y-carriage (1x)
⬢Bearing clip (3x)
⬢M3x12 screw (6x)
⬢Rubber bearing pad 31x16x1 mm (3x)
⬢Plastic bearing pad 31x16x0.5 mm (3x)
⬢M3nN nut (6x) new ones
⬢Push two M3x12 screws through the bearing clip.
⬢Insert the rubber bearing pad on the screws.
⬢Insert the plastic bearing pad on the screws.
⬢Repeat the same for the remaining two bearing clips.
The order of the pads is crucial. Check the order on all three bearing clips.
⬢Note the three cutouts for bearings in the Y-carriage.
⬢Start with the side with the one pocket. Attach the bearing clip on the cutout.
⬢From the opposite side, secure each screw with the M3nN nut. Do not tighten the nuts, 1-2 turns are enough for now.
⬢Insert the bearing into the bearing clip.
If the bearing cannot be inserted easily, you have probably tightened the M3nN nuts too much, loosen them.
⬢The correct bearing orientation: When placing bearings onto the Y-carriage, make sure that they are oriented as shown in the picture. The tracks (rows of balls) have to be on the sides.
⬢Align the bearing so that it is centered on the bearing clip. Approximately the same piece of bearing should be visible on each side.
⬢Maintain the bearing position and slightly tighten both screws. Just barely to maintain its position and orientation. We will tighten the screws firmly later on.
⬢Using the 2.5mm Allen key and the universal wrench, slightly tighten the M3nN nuts. Do not tighten it completely, just secure the bearing orientation and position. We will completely tighten it later.
⬢Attach two bearing clips on the remaining two bearing pockets and push two bearings inside.
⬢From the opposite side, secure each screw with the M3nN nut. Do not tighten the nuts, 1-2 turns are enough for now.
⬢Orient both bearings so that the two rows of bearing balls have to be on the sides.
⬢Unlike the previous bearing, position the bearings as close to the center of the Y-carriage as possible. Beware, the bearings must not touch the edge of the pocket!
Correct bearing alignment is CRUCIAL. Proceed carefully and make sure that both bearings are as close to the center of the Y-carriage as possible and do not touch any pocket edge.
⬢Maintain the bearing's position and slightly tighten the screws. Just barely to maintain the position and orientation of the bearings. We will tighten the screws firmly later on.
⬢Using the 2.5mm Allen key and the universal wrench, slightly tighten the M3nN nuts. Do not tighten it completely, just secure the bearing orientation and position. We will completely tighten it later.
⬢For the following steps, please prepare:
⬢Y-rod-holder (4x)
⬢M3x10 screw (12x)
⬢M3nS nut (12x)
⬢Smooth rod 8x330 (2x)
NOW, PLEASE BE VERY CAREFUL! Gently insert the rod straight into the bearings, do not apply too much force and do not tilt the rod!
In case you manage to push out some balls from the bearings by accident, please count the balls. Without one or two balls, the bearing will continue to work. If there are more of them, please consider ordering new bearings.
⬢Carefully tighten the screws fully into the nuts on the underside. Make sure you tighten the screws EQUALLY and FIRMLY. Each screw must come all the way through the nut, or at least its tip must be aligned with the top surface of the nut.
After the final tightening, the movement of the smooth rods must be gentle. If the smooth rod moves stiffly, loosen the screws and repeat the procedure.
⬢
Now, please continue to step Preparing Y-rod-holder.
These steps are valid only if you have the NEW version of the Y-carriage.
⬢For the following steps, please prepare:
⬢LM8UU bearing (3x)
The bearings come pre-lubricated from our factory and do not require additional lubrication upon initial use.
⬢Y-carriage (1x)
⬢Bearing clip (3x)
⬢Rubber bearing pad 31x16x1 mm (3x)
⬢Plastic bearing pad 31x16x0.5 mm (3x)
⬢M3x8 screw (6x)
⬢Push two M3x8 screws through the bearing clip.
⬢Insert the rubber bearing pad on the screws.
⬢Insert the plastic bearing pad on the screws.
⬢Repeat the same for the remaining two bearing clips.
The order of the pads is crucial. Check the order on all three bearing clips.
⬢The correct bearing orientation: When placing bearings onto the Y-carriage, make sure that they are oriented as shown in the picture. The tracks (rows of balls) have to be in the corners.
⬢Align the bearing so that it is centered in the bearing clip. Approximately the same amount of bearing should be visible on each side.
⬢Maintain the bearing position and slightly tighten both screws. Just enough to maintain the bearing’s position and orientation. You will tighten the screws firmly later on.
⬢Note the three pockets for bearings in the Y-carriage.
⬢Start with the side with the one pocket. Attach the bearing clip on the cutout.
⬢Insert the bearing into the bearing clip.
⬢Attach two bearing clips on the remaining two bearing pockets and push two bearings inside.
⬢Orient both bearings so that the two rows of bearing balls have to be on the sides.
Correct bearing alignment is CRUCIAL. Proceed carefully and make sure that both bearings are as close to the center of the Y-carriage as possible and do not touch any pocket edge.
⬢Unlike the previous single-bearing, position the bearings as close to the center of the Y-carriage as possible. Beware, the bearings must not touch the edge of the pocket!
Incorrect positioning: the bearings must not touch or overlap the edges of the pocket as shown in the bottom of the first picture.
⬢Maintain the bearing's position and slightly tighten the screws. Just barely to maintain the position and orientation of the bearings. We will tighten the screws firmly later on.
⬢After securing the clips double-check the correct position of the bearings so that they do not touch the edges of the pockets.
⬢For the following steps, please prepare:
⬢Y-rod-holder (4x)
⬢M3x10 screw (12x)
⬢M3nS nut (12x)
⬢Smooth rod 8x330 (2x)
⬢Using a paper towel, wipe the transport oil from the surface of the smooth rods.
NOW, PLEASE BE VERY CAREFUL! Gently insert the rod straight into the bearings, do not apply too much force and do not tilt the rod!
In case you manage to push out some balls from the bearings by accident, please count the balls. Without one or two balls, the bearing will continue to work. If there are more of them, please consider ordering new bearings.
⬢Tighten the screws on each bearing clip.
After the final tightening, the movement of the smooth rods must be gentle. If the smooth rod moves stiffly, loosen the screws and repeat the procedure.
⬢After tightening all the screws securing the bearing clips, make a final check of the correct position of the bearings:
Two-bearing side: the bearing must be positioned closer to the center of the Y-carriage. It must not touch or extend over the edge of the pocket.
⬢Single-bearing side: the bearing must be in the center of the pocket.
⬢Take one Y-rod-holder and insert two M3nS nuts.
⬢Make sure you've pressed the nuts all the way in. You can use pliers, BUT be careful, you can damage the printed part.
In case you can't press the nuts in, don't use excessive force. First, check if there isn't any obstacle in the nut trap.
⬢Insert one M3nS nut from the side of the Y-rod-holder.
⬢Ensure and adjust the alignment of each nut with the 2mm Allen key.
⬢Repeat for the remaining Y-rod-holders.
⬢Push one of the Y-rod-holders onto the rod. Align the front surface of the plastic part with the flat surface of the rod.
⬢Check the correct position of the Y-rod-holders. The screw hole must be facing up and towards the center of the Y-carriage (see the picture).
⬢Repeat for the remaining Y-rod-holders.
⬢Take the Y-carriage including smooth rods with rod holders and place them in YZ-frame. Make sure, that two bearings are on the left side (see the picture, there are two pairs of the screw holes on the left and one pair on the right).
⬢Secure each Y-rod-holders and fix them with M3x10 screws on the front plate (the one with the longer extrusions). Tighten both screws equally, but not completely. We will tighten them fully later on.
⬢Insert the M3x10 screw into the hole in each front holder and tighten them.
⬢Secure the second pair of the Y-rod-holder with two M3x10 screws. Tighten both screws equally, but not completely. We will tighten them fully later on.
⬢Insert the M3x10 screw into the hole in each rear holder and tighten it.
In case the M3nS nuts keep falling out, please flip the frame upside down. Tighten both printed parts and then return the frame to the original position.
IMPORTANT: proper alignment of the smooth rods is crucial to reduce noise and overall friction.
⬢Move the Y-carriage back and forth across the entire length of the smooth rods to align them.
⬢Then move the carriage to the front plate and tighten all screws in the front-Y-holders.
⬢Move the Y-carriage to the rear plate and tighten all screws in the back-Y-holders.
⬢For the following steps, please prepare:
