Hi,
I want to build same system with 20x60 mm . Which parts should be change?(i want it 1500mm length option) I should buy it as soon as possible...It's an urgent issue...

Thanks

 

The example photo with the mini V logo below, I want to build that! Looks like a perfect setup for a 3D printer where the bed doesn't move. My only concern is the z axis might not be able to make small movements. Would you have a BOM for that specifically?

 

Thanks for the info. It looks like only the z-axis is 20x20. The x-axis and y-axis appear 20x40. Any idea when the actuator end mounts will be available?

 

Hi, if I want to build a 14 mtr linear actuator is it possible using this setup only by extending the V slot profile? thanks

 

Thanks Mark, I will give it a shot.

 

Hi, For the NEMA 23 stepper motor, does the V-slot Actuator Mount able to fit? If not, what are the recommend replacement parts?
Thanks

 

I think the Mini V Plate is missing from the BOM at http://www.openbuilds.com/builds/mini-v-linear-actuator-build.48/

 

Great design solution! What do you think, is it strong enough to build on its basis cnc router to cut wood, plastics and maybe aluminium? I mean for example on OX or Routy wheels holds v-slot up and down

 

Dear Mark, I made the 14mtr length linear, but i encounter a problem when the cart go through each of the joint. The cart will vibrate making it unstable. Any recommendation to solve this problem? Thanks

 

Thanks @Rick 2.0 and @kram242, your advise are most helpful!

 

I understand one now needs to mount the motor flush with the end mount, but it seems to me there is no way then to properly center the timing pulley (having the set screw on the flat bit of the motor axis).

The parts needed to mount the idler pulley in the end mount are missing. The screw provided in the pulley kit is too short, and given the width of the end mount is around 32mm, there is no way the 30mm screw contained in the list is long enough. The spacers in the video are also absent from the list.

Or did I miss anything (which happens...) ?

 

This looks like a great build to create a camera slide for my very small and light GoPro Hero 4 video camera . It appears that I could attach a tripod mount to the lower edge of the rail and the camera could travel along on a gantry plate driven by the belt drive. It could be used in time lapse and night lapse sequences giving the impression of moving through the time lapse sequence. My question is related to the motor drive. I am wondering if a step motor is the appropriate motor as I would want the camera motion to be very slow, perhaps covering 1000 or 1500 length in one or two hours. Ability to vary the speed would be nice. Any suggestions as to motors and controllers for a guy who sway over his head in matters electrical. I would need to use the unit in the field and would require battery powered motor. Thanks in advance for any suggestions.

 

Hi Mark,
The parts list is not complete, which was a bit of a shame as I ordered parts for six linear actuators delivered to me in UK. The parts list states you don't need aluminum spacers, but you do for the wheels on the gantry plate and the idler pulley. You also need 6mm M5 low profile cap screws for attaching the end caps/motor mount/idler pulley. Moral of the story is; double check your build from the 3d models.

 

Thanks for the reply, Mark. I have ordered some more parts and then realised I still needed some extra spacers and screws so I have message bombed the OpenBuildPartStore - as I am trying to avoid multiple packaging costs if possible. The bits that have arrived really are top quality and most pleasing to a geek like me! I am itching to get my build under way.

Question: The actuator bundle shows optional Nema 23 motors. The End mount, however, says it's for Nema 17 motors. Do the 23's fit? The build video also references nema 17 motors.
