Helix drive system
The helix screw, due to it’s high lead value, can be used for hight speed applications such as 3D printers.
List of plastic parts:
Assembly of the Flanged nut holder
You will need the specific flanged nut specialy made for the high helix screw
You will find specific holes for the Nuts on one side of the plastic part.
Secure the flanged nut on the plastic part using the 2 screws and the nuts.
Align it with the 2 screw holes on the middle of the plate.
The direction of the part is not important as the holes are centered on the bed.
Insert 2 M3x12mm screws.
Place the motor holder on the same side as your Y Axis Motor.
You will need to unmount your existing Y Axis motor and mount if on this new plastic part.
Make sure to unmount the Y Axis motor and also removes it’s coupler.
Note that you will adjust the position of this motor later on.
Pllace the bearing inside it’s housing.
If it’s going out, you can use some liquid paper glue . Make sure you let the center of the bearing free.
We are now going to align all the parts togather so that the high helix screw stay straight.
Move the bearing holder on the side if necessary. (Make sure to unscrew the M6x12mm holding screws before moving this part.).
you can also set free the holding screws (M6x12) during the alignment process
You can slide the bed forward and backward in order to ease the process.
If you push the coupler too much it will rub against the steel rod.
Also tighten the M6x12mm screws on both sides.
it should be smooth all along it’s way.
You can let free the motor holder and the idler bearing holder during this phase. They should align correctly by themselves. Once the bed is a the maximum on one side, hold the plastic part on this side with your hand and push the plate on toward the other side. Then screw the plastic part you held in your hands
Proceed the same on the other side.
Insert the nut inside the extrusion profile groove and tighten the M6x12mm screw.
Same thing on the other side.
On electronic side
On electronic side you will need to invert your Y axis motor connector, Otherwise the motor might pull/push the bed on the wrong direction.
