Technical Details

  • The greenLean CNC machine is intended to be positioned against a wall. You will need a clear height of 80 inches minimum, but more if you intend to access the top of the machine. Standard ceiling height is generally 96 inches (8 feet).
  • The length of the machine is 116 inches (9ft 8 in).
  • The ribs of the CNC machine are spaced 16 inches on center exactly, so the machine can be fastened to studs using provided brackets.
  • The greenLean CNC machine rests on the ribs of the machine and each rib has a support called the rib foot that is adjustable to the irregularity of shop or garage floors.
  • To make sure there is optimal rigidity maintained, the z-axis features a very tight organization of mechanical parts, hardware, structure and the spindle.
  • The greenLean CNC machine requires the 2.2 kW spindle since it has a uniform body and is set into the z-axis making it very close to the z-axis and y-axis bearings.
  • This z-axis portion of the CNC machine weighs approximately 30 pounds and is counterbalanced using a constant force spring tucked into the gantry.
  • The X and Y axes use heavy duty 651 oz-in stepping motors as they are dealing with the most inertia and weight and use roller chain and sprockets for motion. The roller chain for the X axis have chain rests that will allow better tension on the chain. The Y axis chain is, for the most part, vertical, so this will enable better tension as well. Both X and Y drive sprockets are #25 with 14 teeth at .25 inch pitch.
  • The Z axis motor is coupled to a lead screw which uses a medium duty 425 oz-in stepping motor.

13
Attach lower X axis rail assembly

Repeat the X axis rail assembly steps above to complete the lower X axis rail assembly.

Once all of the rails and parts have been installed loosely, tighten all of the screws working from the end screws first, then at the midpoint of each screw tightening. While the tightening is in process, keep an eye on the straightness of the rail by peering down from one end of the rail to the other. the ribs may also need adjusting to keep the rails straight.

14
Install top chain rest

Fasten the top roller chain rest at the top of the ribs. The chain rest should be positioned so that there is equal space (ribs) on either side.. Use twelve (12) 1/4 x 1-1/2 inch screws and twelve (12) cross dowels. Make sure the orientation of the chain rest has the counter bored holes closer to the rail.

15
Install lower chain rest

Repeat the previous step for the chain rest at the lower portion of the ribs.

16
Attach the X axis chain mount

Loosely attach the chain mount to the end of the X-axis rail support using two (2) 1/4 x 1-1/2 inch screws and two (2) cross dowels.

17
Install remaining X axis chain mounts

Repeat the previous step for the remaining X axis chain mounts. When the gantry is mounted and the chain is attached to these mounts, adjust the mounts to align well with the gantry sprockets and tighten the screws holding the mounts.

18
Install side bearings to the CFS bearing truck

Constant Force Spring (CFS) Bearing Truck Assembly

Attach the side bearings to the main bearing truck plate at each slot shown using two (2) 5/16 inch bearings (608ZZ), three (3) 5/16 inch nuts, two (2) 5/16 inch narrow washers and one (1) 5/16 x 2-1/2 inch screw. Since these are open slotted areas, tighten the two nuts at either side of the slot slightly so they will be able to move with a little bit of force and press against the sides of the gantry at a later step.

19
Attach the bottom bearing mount to the CFS bearing truck

Attach the bottom bearing mount using two (2) 1/4 x 1-1/2 inch screws and two (2) cross dowels. Attach the wire rope holder eye bolt to the front of this mount using one (1) 1/4 x 2 inch eye bolt and one (1) cross dowel. Screw the eye bolt in completely.

Gantry Assembly

Attach the v-groove adjustment screws into the gantry bottom ends using two (2) 1/4 x 1-1/2 inch screws and two (2) cross dowels. The screw should not enter the slotted area reserved for the v-groove bearing assembly. These screws will be used for adjusting and pressing the v-groove bearing against the rail in a later step.

23
Install v-groove bearing assemblies for gantry bottom

Attach the v-groove bearing assembly as shown. The bearing assembly that is installed with the wood spacer is used to guide the wire rope for the Constant Force Spring counterbalance. The other two assemblies are use for the x-axis rail. Each rail v-groove bearing assembly consists of one (1) 3/8 x 2 inch screw, two (2) standard 3/8 inch washers, one 3/8 inch narrow washer and one (1) 3/8 inch nut. The wire rope v-groove bearing assemblies do not use a washer on the screw head side as shown in the illustration and use a 2-1/2" inch long screw rather than a 2 inch screw due to the inclusion of the wood spacer. Very important: make sure the narrow washer is installed between the standard 3/8 inch washer and the v-groove bearing. The bearing will not spin if this narrow washer is not installed correctly. The narrow washer prevents the outer race of the bearing from touching the larger washer.

24
Install v-groove bearing assemblies to the gantry bottom

Using three (3) 1/4 x 1-1/2 inch screws and three (3) nuts, fasten the NEMA 34 (Large) stepper motor to the x-axis motor mount as shown in the illustration. The motor mount does not need to be placed in this location for this step. Make sure the wire outlet on the motor is facing up.

30
Attach the x-axis motor mount to the gantry back

Attach the x-axis motor mount to the gantry back using two (2) 1/4 x 1-1/2 inch screws and two (2) cross dowels.

31
Couple the x-axis rod and drive pulley to the NEMA 34 motor

Insert a 1/2 inch to 1/2" rigid coupling to the NEMA 34 motor rear shaft. Don't tighten the coupling until a after the roller chain is installed on the gantry at a much later step. Insert one of the two 1/2 inch rods into the other side of the coupling. Slide the drive pulley onto the rod in the orientation shown in the illustration.

32
Insert 1/2 inch bearing into the x-axis bearing support

Insert one (1) 1/2 inch ID (inside diameter) bearing into the bearing seat on the x-axis bearing support. the bearing may need persuasion to be inserted into the seat. You can use a vice or clamp, or use a mallet, or a hammer to bring the bearing into the seat. If a hammer or clamp/vice is used, use a piece of wood to protect the bearing in this process.

33
Attach the bearing support to the x-axis gantry back

Attach the bearing support to the gantry back using two (2) 1/4 x 1-1/2 inch screw and two (2) cross dowels. To place the bearing support into the proper location, the rod will need to be inserted into the bearing first and then moved axially into place.

34

Position the constant force spring and bearing truck

Position the constant force spring and bearing truck. The loop of the constant force spring should be wrapped around the constant force spring axle. The bearing truck and constant force spring will be tightly bound at this point. Both springs will be used in the same location.

48
Add the wire rope to the CFS bearing truck

Attach one end of the wire rope to the eye bolt with a ferrule. Thread the end of the wire rope through the eye of the eye bolt and curl it around. Use a ferrule to hold this loop of wire rope together. Crimp the ferrule tightly to provide a very secure hold on this loop with a crimper, wrench, clamp or vice grips. Make sure the crimp is very tight. You can optionally use an extra ferrule (not included) to wrap the tail of the end of the wire rope back on itself for a more secure hold if desired; however, this will need to be planned and done prior to the crimping.

To keep best management of the wire rope during the next many steps, route the wire rope around the v-groove bearings as shown and tape the remaining wire rope to the body of the gantry and also on the v-groove bearings so the wore rope does not become removed from the groove.

49
Install nut inserts on the gantry front

Fasten twenty two (22) 1/4 inch nut inserts with an allen wrench into the gantry front. The holes reserved for these insert nuts are slightly smaller than the holes reserved for cross dowels. Also, all of the cross dowel holes will exhibit an intersecting hole and the insert nut holes will have no intersecting holes.

50
Attach gantry front to gantry bottom

Attach the gantry front to the gantry bottom using nine (9) 1/4 x 1-1/2 inch screws and nine (9) cross dowels. Make sure to orient the side wit the nut inserts toward the inside of the gantry. The 3 inch square opening is at the bottom and closest to the constant force spring axle.

51

Fasten the top gantry side to the gantry rear support using two (2) 1/4 x 1-1/2 inch screws and two (2) cross dowels.

76
Position the gantry onto the X axis rails

This step may require a couple people to complete. Rest the top bearings of the gantry onto the top X axis rail. Make sure the top bearings are loose enough to move within its slot. Also, make sure the X axis rail supports are loosely fastened to the ribs so the X axis rail support have some play up and down.

Once the upper bearings are resting on the top rail, align the top of the bottom set of bearings onto the top of the bottom X axis rails. Move the bottom X axis rails up against the bearing so that the bottom bearings are in-line with the bottom rail.

77
Gently tighten the v-groove adjustment screw at the top of the gantry

Gently tighten the v-groove adjustment screw at the top of the gantry. Only use slight tightening. Over tightening will damage the rail. A good rule of thumb is to spin the v-groove bearings while tightening. When the v-groove bearings stop spinning and the gantry moves when you try to turn the bearing, the screw will be tight enough.

78
Gently tighten the bottom gantry bearings

Repeat the process from the previous step to tighten the lower bearings.

Errata: Use two (2) of the thumb screw provided since there will be very little space for a screwdriver to fit between the floor and the gantry side.

79
Tighten the X axis rail supports to the rib structure

Move the gantry to the far left of the ribs structure and tighten only the leftmost screws on the top and bottom rail supports. Move the gantry to the far right and tighten the rightmost screws of the top and bottom rail supports. As you complete this process, keep an eye on the alignment and straightness of the rails by peering down the rail from one end.

Repeat this process by tightening the rail supports at the mid point of each tightening. For instance, the next tightening will by at the midpoint of the X axis rail, so the gantry is moved to the midpoint and the screws at the midpoint (next to the gantry) are tightened.

Ss you secure the X axis rail supports and you notice an issue with straightness, loosen the X axis rail support and repeat the above process.

80
Route the lower X axis roller chain around the sprockets

Route the lower X axis roller chain over the drive sprocket and under the idler sprockets using the longer roller chain in the kit. Make sure the drive sprocket is loose during this installation. The drive sprocket will not be tightened until the roller chain is fixed at both ends and the gantry is moved to make sure the drive sprocket is well aligned with the sprockets.

81
Route the top roller chain around the sprockets

Repeat the previous step for the roller chain at the top of the gantry.

82
install the eye bolt to the chain mount

The eye bolt will serve as the tie to fix the end of the roller chain. Install the eye bolt assembly using one (1) 1/4 x 2 inch eye bolt, one (1) 1/4 inch washer and one (1) 1/4 inch nut.

83
Fix the roller chain to the eye bolt

Affix the roller chain to the eye bolt using two (2) # 4 x 3/4 inch screws and two (2) #4 nuts. Thread the end of the roller chain through the eye of the eye bolt and curl the roller chain around to itself and fasten the chain within the links using the #4 hardware.

84
Fasten the end of the roller chain

Fasten the end of the roller chain using the #4 hardware as shown.

85
Affix the remaining eye bolts and roller chain ends

Repeat the previous steps to complete the remaining eye bolts and roller chain ends. During this process, make sure that the drive sprockets and the couplings around the X axis are loose so when the roller chain is tensioned, those mechanical parts can move freely and not cause the gantry to rack.

Tension the roller chain so there is little deflection on the chain, but don't tension the chain too much.

86
Attach adjustment screws to the ZY plate

ZY Plate Assembly

Attach the v-groove adjustment screws to the ZY plate using one (1) 1/4 x 1-1/2 inch screw and one (1) cross dowel for the top and one (1) 1/4 x 2 inch screw and one (1) cross dowel for the right side.

Attach the mount and idler sprockets to the ZY plate

Fasten the Y axis stepping motor mount and idler sprockets to the four screws using six (6) nuts and two (2) idler sprockets.

Errata: Include two 3/8" nuts on the 3/8" screws that will receive the idler sprockets. These nuts will hold the idler sprockets in place. Between the idler sprockets and the Y-Axis motor mount, add a 3/8" standard washer against the mount and a 3/8" narrow washer between this washer and the idler sprocket. This will enable the idler sprocket to spin freely and the not washer combination will hold the idler sprocket securely in place.

113
Assemble the drive mechanics to the Z axis assembly

Assemble the drive mechanics to the Z axis assembly using one (1) 1/2 inch lead screw, one (2) 1/2 inch narrow washer, one (1) 1/2 inch flexible coupling hub and one (1) flexible coupling spider. Insert the lead screw through the 1/2 inch ID bearing. slide the washer over the lead screw and fasten the coupling hub so that the end of the lead screw is flush with the other side of the hub.

Errata: Add a 1/2" bearing, 1/2" narrow washer and a 1/2" collar to the other side of the bearing mount on the lead screw. This will stabilize the lead screw axially. Make sure the bearing is against the bearing mount and the washer is between the bearing and the collar so the outer race does not rub against the collar.

114
