Neje max 4 E80 XXL Extension project

Hi, I’m planning to customize or extend the Extension Kit from
750mm x 1030mm to 750mm x 1620mm.

I will connect (lenghten) the standard green Y- axis aluminum profile to the extension Y-axis profile by making my own custom CNC steel cross connectors + reinforcement plate to strengthen the profile and avoid wobble.

But I would like to know what kind of timing belt is used for the motor? I need at least 200cm, is it GT2 belt?

I will update my progress in this topic.

yes

any progress? I do not need it longer now, but am thinking about a project that would require the longest extension I could get.

It’s the GT2 belt, what’s the progress you ask?

I was asking @Holtwerk how they were doing with attaching rails to each other with the [quote=“Holtwerk, post:1, topic:9351”]
custom CNC steel cross connectors + reinforcement plate
[/quote] they discussed.

Ok update, the person who is CNC milling the extension an reinforcements parts has a knee injury… this person is 3 weeks absent from work… (sigh…)

However, he already made my steel reinforcement parts that connects the rails from the sides.
I also told him to drill M5 holes into the neje rails so that the steel reinforcement bar (as mentioned above) will connect to the rails.

He has assembled these parts and made measurements with the cnc machine: this part alone makes it already a very sturdy construction, but there is a 0.03mm difference in height between the transition between the 2 rails. (Maybe this is not a big issue, can’t test it now)

I’m waiting for the cross connectors to be made (these slide into the rails, I think these custom parts will make the difference in height go away.

My 2meter GT2 belts have arrived.

I keep you updated

see update

I am looking forward to pictures.
