Amazing job!, i agree with other users that there could be play in the block if you dont prevent the lead screw from moving axially. If you buy the standard pillow bearings they come with tiny setscrews and they allow you to fix in place your screw. The alignment will be a bit more challenging but it will make it a solid, flawless design.
it would be really helpful if you mention the link for purchasing the above used components
Ah yes 6 times 3 equal 18.Thanks so much that table really help
HAHAHAHAHAH😂😂 Sama2😁
What is the accuracy? can we get target 0.02 to 0.05 mm accuracy?
Good work
Thank you😁
thanks

how to buy parts for this project?
How to choose our motor
Hi how to install that
Did u use 20x40 aluminium extrusion for both base and block??
Yes😁
@@ikmalxhakim4419 sir can i have a link for purchasing t slot
Motor's typically have significant end-play, a mm or two, so without a thrust-bearing that will limit the accuracy/repeatability significantly... For instance there's no need for an anti-backlash nut on the leadscrew if the motor shaft has 1mm endplay (and that coupling can stretch/compress by a similar amount too. If you look at the standard ballscrew kits they come with a preloaded thrust bearing block to define the axial position to tight tolerances.
Oh, I'll look into it. Thank you!
if that were true, then every 3D printer with a screwed z axis would have that problem which they dont, and those use extreamly cheap steppers.
@@guillermomarturetfendt9037 Z-axis has gravity to prevent backlash.
The holes that you are drilling at 0:28, are these tap holes strong enough to hold the track? I think the thickness of the extrusion material is only 1.5-2 mm, you need at least 3-4 mm for strength
Sorry for late reply😅 and thank you for advice, Yes, it doesn't strong enough to hold the track.😁I noticed there's tiny play when I try to wiggle it.
@@ikmalxhakim4419 I thought of using 20x40 extrusion, but since your speaking, it requires 3 to 4 mm thickness for having a good strength(for the bolt)... I'm at little bit confused to wheather use that or not for my project....Any help?
@@sharanamuram2290 what I can recommend is to use T slot nuts instead of tapping the hole. This surely holds the rail enough and more reliable.😁I made a V2 linear actuator (I posted on my insta) in which stepper mount is 3d printed parts and one single 2020 aluminium extrusion. Since I use MGN12 linear rail, I still can use 5cm length 2040 profile for the block carriage. (NOTE: my design here is only applicable to MGN12 rail (block) due to the hole size & spacing )
@@sharanamuram2290 or use T-nuts as it's what extrusion are for. Here the wrong extrusion profile was used.
Do you have a parts list where can I get these parts?

Hiii, can you how us the wiring and conections of the actuator?
I used this actuator for my 3D printer. I wired it up to the Arduino Mega and RAMPS 1.4. This video might help with connecting the stepper motor to the RAMPS:😁

If you're interested, I also built a linear actuator V2 with 3D printed parts, which is more reliable. I just don't post it on RUclips.😁🙂

Is there a way to have these in 3 or 4 meter long config?
Hi, my design here is only works for MGN12H series linear rail. So, its not possible for such a long rail😮
@@ikmalxhakim4419 awwwwwwwwww

What is the name of the golden nuts?
deez nuts
The brass nuts on the rod are anti-backlash nuts

bang kunci L hexagonalnya ukuran berapa?
Its for M3 hex nut, so might be 2.5mm
1:33 The slotted holes look like they were made by chewing.
UPDATE: I created DIY linear actuator V2, which is more reliable than this. If interested, please visit this link:
