I’m looking for some detailed pictures to rebuild this track from Akiyuki’s spiral lift so I can create a loop with the ball cleaner.
-
The right switch underneath the pressure gauge operates the L-motor and lowers the cloth on the balls simultaneously.
-
@HRU_Bricks I was struggeling with the same problem. I don’t have any additional pictures. I have taken this picture as one of my prototype builds. https://www.bricksafe.com/files/Juroen/building-tech/A83D65C0-AB9C-4373-8689-17D0813395AB.jpeg/1920x1440.jpg However this switch operates the clamping of the balls instead of raising/lowering the L-motor... Therefor I don’t think you need to open the valve completly as these cylinders for clamping are relatively small.
-
@HRU_Bricks Looking forward to see the video of the compressor! Ballfactory looks awesome, do you have it running at full speed?
-
Wow, looks great!
-
It was a nice challenge to reverse engineer this design. That’s what it’s was about for me. At this moment I don’t have the intention to run it for hours. As I will have only one GBC module, I’m not planning to attend any exhibitions. The ball cleaner has 7 48mm medium cylinders of which one is only used for the pressure switch and 2 32mm small cylinders. Not all cylinders are operated at the same time and there’s an airtank built within the module. Nevertheless using an external air compressor feels like cheating to me. I will build the XL version with unreinforced cylinders and see how that goes. If necessary I’m upgrading to XXL.
-
@HRU_Bricks Which part no. cylinders did you use?
-
@Lego_GBC_NL I have solved the part, it was an axle pin with an axle connector 2L. I will first add the additional color sensors and the rest of the pneumatic hoses. I have decided I will build the Quanix air compressor as well. Glad to hear it runs smooth. I think the minimum requirement for the ball cleaner will be 2 compressors. Probably will start with the compressor in 2 months. Did you use the reinforced cylinders? https://www.bricklink.com/v2/catalog/catalogitem.page?P=bb875&C=7#T=C&C=7 @HRU_Bricks I will send you pictures when I have finalized build. However I have build this module by just looking at the YouTube videos and the pictures provided by @9v system.
-
I finally found some time to continue on the build. I have connected all motors to the EV3-brick. Everything is running fine. Only 3 more color sensors to go, altough these are not really necessary for the operation. But I may use these for positioning all components before running the program. Also figured out the pressure switch and started to connect the first pneumatic hoses.
-
Second test run, seems the axles were indeed bent. Replaced them by straight ones. Everything runs smooth.
-
Programming the EV3, connect all pneumatic hoses, set the correct timing of the switches. Still need some more light sensors, cables and working out the switch for the up/down gripper movement and pressure switch.
-
I still have a lot of work to do on the ball cleaner. I will not make instructions. I will take pictures when the module is reliable.
-
@Ankoku @drullph20 Thanks, I will check straightness of the axles. I thought they were straight when I mounted them. Probably better to check once again.
-
Today I did a first testrun with the ball cleaner. The horizontal translation of the grippers seem to have to much friction. Servo motor is running at full speed. Any suggestions are more than welcome. I will sort out the mechanical and electrical part first before starting with the pneumatics.
-
@drullph20 Thank you for your pictures. I have a similar set-up but the upwards movement doesn’t run smooth. Loaded with a few balls makes it worse. Do you have the same problems with the 8 tooth gear?
-
@drullph20 How did you build the gearing of the first stepper part with the M-motor? I’m not very happy with mine, it doesn’t run very smooth. I have used a 24 tooth clutch gear and a 16 tooth gear.
-
Thanks, I have already found some custom made cables. Ordered 1 piece to see if it meets my expectations.
-
I’m looking for 100cm EV3 cables. Does anybody have experience where to buy them?
-
Wow, looking great! You are almost done, I have a long way to go though! I’m currently working on the timing of the pneumatic switches. Also waiting on some parts.
-
As I am stuck on a few parts of the ballcleaner-module I have contacted Akiyuki on his website akiyuki.jp, with a link to my previous posts and some additional bricksafe-links. I think he will get too many requests for any additional information on his modules. But for now I will wait. Anybody got some experience with corresponding with Akiyuki?
-
Apart from reverse engineering and building with complete instructions, bricks aren’t cheap..
-
Wauw, people building 4-5 Akiyuki modules in one year. I will be quite happy to finish at least one...
-
Yes indeed, just by looking at videos and pictures. I think I have seen the videos hundreds of times. Still no luck on the grey parts though, but I’m not in a hurry. I think 9v system lost the file. I have asked him already but he couldn’t find it up to now.
-
Almost time to start with the EV3 parts.
-
If it is not too much trouble, can anyone help me identify the 3 yellow parts and the gray axle part? https://bricksafe.com/files/Juroen/building-tech/88BFBBDC-2ECE-4D6E-8B3F-915ED55CD0A1.jpeg I am waiting for my ordered parts, next week I will post an update on the ball cleaner. Does anyone have the original EV3 program by Akiyuki?
