To reduce the jumping you may be able to reconfigure your servo arm so that the feed mechanism is connected behind the pivot and rotates outward and stops in the forward position. This way you get natural acceleration and deceleration that approximates the sin() of the rotation. Linear speed would then be lowest at the start and end of the stroke, and highest in the middle of the stroke. With the mechanism connected at the current position, acceleration is highest at the very start of the feed. This is something I've been thinking about for my own design.

hello sir, what microcontroller or hardware you used to control the machine and to use the software and upload the PCB files

Great design! Just one thing... try to avoid these type of servos, after few hours of work, will no longer perform like a new one.

You are right. These are really not suitable for 24/7 operation time.

Hi Mica, I face the same "problem", your idea looks just perfect for my needs (...and for others i guess!). Especially the solution with the lower height in the backside! Is it possible to share the 3d printer files? Have you convert other sizes too? I mean 12mm, 16mm, 24mm etc. BTW what are these jumps of parts? (probably nothing as the nozzle supposed to have take the parts before ...) Thanks in advance Simon

Hello, right now I have only 8mm version available because I was not sure If it will actually work. I will surely make the other sizes soon. I can publish output files (STL and STEP) on my blog. I can share Solidworks files over email (Contact me), but I wasn't able to make a full import of STEP files. I just added new features on STEP models... Jumping is caused by pushrod when it moves back to next hole in tape. I guess its not an issue that have to be solved, you should pick the part as soon as its available.

@@MicaCZ Great! Thanks for your quick response. It will be great to have an STL model for printing just to test how this version fits on my machine. How can i download the file (ready to print) from your Blog? I don't think i need the step files as i don't have the Solidworks software and i m not a 3D expert, so... maybe another time. Thanks again! Simon

Hello I need one of these feeders, how much does it cost ?
@MicaCZ 3 жыл бұрын
The cost depends mostly on the price of 3D printing. In my case the price is around 10USD for all parts (Including servo, motor, switch and springs). It's really cheap...
