Dear forum members,
This is my first post and I hope I am doing it right.
I came across a Yamaha cartesian robot. (My company was going to scrap it)
It has very nice linear rails and brushless servo drive which is connected directly to the ball screw.
Now, my question is if you could help me use it for my DIY CNC router project I have in mind?
The problem is that I don't know if there is any easy way to control the AC servo motor with the build in encoder using a modern hobbyist grade CNC controller.
I will upload pictures of the cartaisian robot later. I found the following information on the labels:
- Tamagawa BRX Smartsyn, TS2620N654E122
- TBL-i N 112, E200
- The robot controller is Yamaha DRCX: https://www.yrginc.com/Catalog/PDF/C...CX_E_V6.08.pdf
- Yamaha DRCX
My plan for the DIY router is:
- work area around 40"x30"x8"
- cheap (~1000$) but somewhat rigid enough to work with Aluminum
- I'm planning on using 4x8cm aluminum extrusions that I have laying around but everything else still needs to be obtained including the controller.
I thought I could use one axis of the robot for the Z-Axis.
I also thought about just using the rails and the ball screw but the screw is also the drive shaft of the servo motor at the same and the thrust bearing for eliminating backlash is mounted directly on the encoder.
The motor mount is also not compatible to the Nema motors because the holes are about 50mm apart.
So it is probably difficult to use it with conventional stepper motors or am I wrong?
I would really appreciate it if someone could tell me an easy and cheap way to use it.
Thank you!
