Part 3) Hiwin linear rail mounted onto openbuilds cbeam X axis
Hiwin Linear rail mounted onto openbuilds cbeam X-Axis
The install of the Hiwin Linear rails onto openbuilds cbeam wasn’t plug and play, it required some grinding of the v-slot by 2mm so t-nuts could slide onto the profile. I took my time doing this because the grinder could easily destroy the profile. overall it came out okay besides from a few scratches here and there.
Below image shows 1mm sanded from the outer edge of the T-nuts. This is required to slide the rail onto the profile.
lastly some loctite to every bolt and slide it on like a glove.
The Hiwin MGW15H rail fitted onto the c-beam adds a lot of extra strength and rigidity to the X Axis.
(Hiwin Rail measures at 10mm thick by 40mm wide by 500mm long harden steel).
combined with c-beam profile with x3 steel rods through it with epoxy + sand.
- Cost of Hiwin MGW15H Est:$200-$300
- Would I do it again? Yes, though there is a Chinese version for 1/3 the cost if anyone has used that id love your feedback.
Custom gantry plate to merge X axis to Z axis
For this process I used a 3d printed template for a drill guide which worked out well. Below is a image of the stl i made (if you require then please email me)
Its always good using my 3d printer for cheating methods like this. But always measure everything 3 times and drill once.
Above image shows x2 mgw15h tracks mounted to openbuilds xl gantry plate.
Bolting X and Z axis together
Okay last part was pretty straight forward just need to bolt everything together as you can see in the photos.
above image shows z axis profile, as you can see all the channels are filled with epoxy and 3 of them have 12mm steel rods through the profile.
The moment of truth!.. Bam! everything lined up perfect.
all done and ready to bolt onto the frame of the machine
I’m happy that everything turned out to plan.
