bed installation under the bed
In this section you will need:
- Scalar S: 0.9 meters GT2 belt for 300mm VSlots
Take as a reference one side of the guide
You have only 1 guide support on each side and a 300mm long extrusion profile between.
On each side you have 1x 16 teeth pulley
The belt goes inside the extrusion profile groove on top and is then tighten at the bottom under the carriage plate.
Here is a sliced view of the whole assembly.
The final goal is to have the belt in this state
Note that the Belt’s teeth are always facing the pulleys.
Take the belt and push it on one side, inside the top groove. The teeth must be facing downward.
Push it until it exists on the other side.
Once at the end, turn it so that it goes inside the bottom groove of the extrusion profile this time.
When the belt arrives at the middle of the carriage , it needs to go inside the middle hole of the bottom plate of the carriage.
Pull it enough so that you can clamp it with the dedicated plastic clamp. Make sure you have enough belt left so that you can tighten it later on.
Remove the 2 xM3X8 thermo screws that keeps the clamps screws, push the belt between and screw back the clamp.
On the other side, it’s similar, you need to push the belt inside the bottom part of the extrusion profile up to the middle of the Carriage. Then push it in the middle hole. Don’t clamp it yet.
Note, if one side of the belt is properly clamped you should be able to tighten the belt and perform the final clamping of the belt.
You can also tighten the belt on both sides if you feel the need for it. One side should be enough .
The belt arrives near a kind of belt guide that will keep the belt centred.
The belt is then pushed inside the middle groove and is placed between the clamp and the bottom carriage
If needed we tighten the belt (Only if 1 side is properly clamped).
Tightening the Pulleys
Now that your belt is installed you Must screw your pulleys on both motor and idler side.
