List of parts :
- 1 smooth rod support integrating the pre wired end stop.
- 1 x 8mm (Scalar M) or 10mm (Scalar XL) smooth rod compatible end stop support
- 1 End stop with a wheel
- 2 sets of M6x12mm screw and it’s T-Nut
- 2 cable ties
Assembly of the Y axis end stop
Here we placed it on the top rod, but you can place it on the bottom one if you feel the end stop doesn’t hit the X carriage
The main prupose here is that the wheel would hit the X carriage to signal to the electronic that the carriage has reached the MIN position on X axis.
Also secure the end stop on it’s support using 2 cable ties.
If the probe wire is causing trouble, you might consider placing this end stop on the bottom smooth rod.
Also check that the end stop support is not moving on the smooth rod to avoid possible future issues.
At this moment check that the nozzle position over the heat bed is reaching the border of it. If it’s not the case, just readjust the location of the end stop a little bit in order to achieve this goal.
In order to make sure tat the end stop is properly attached to the smooth rod, you can constraint it using the cable tie and secure the end stop lead wire with it as on the picture making sure it’s going behind the threaded rod.
Y Axis End stop installation
This items should already be assembled . You might need to remove the protective scotch however before using it.
You should have on your chassis 3 identical heatbed smooth rod supports and 1 other with the integrated end stop holder.
It is to be placed on the opposite side of the power supply, also on the opposite side of the Y axis motor on the same extrusion profile.
(Goodies) Assembly of the Y axis end stop
Take the plastic support that is compatible with 30×30 slots.
Prepare a set of M6x12mm screw and a T-Nut.
Place the end stop so that the contact side is placed toward the outside of the part. Also center the end stop so that the dedicated holes on the plastic part for securing the end stop are aligned with the end stop holes.
The photo shows you how to place it.
A good tip is to make sure that the cable ties heads are placed on the left of the plastic part. The picture should help you to place them properly.
The lead wire of the end stop can be placed like on the picture, afterward the motor wires and the end stop wires will follow the some path.
This position is also nice to protect the contact metallic plate from being broken.
Installation the Y axis end stop finger
Now take as reference the linear bearing support located the closest to the Y axis end stop.
On this photo the Top left linear bearing support
Then go right again for 10 mm (1cm) and make a 2nd mark.
Both marks will be used to locate the screws for the Y axis finger holder
A M3X20mm screw and 2 nuts are to be used in order to adjust the Y MIN position of the heat bed.
