The fixed support is on the opposite side (far end) and motor coupler replaces the other not fixed support. It's not an OMG moment. My cut results are amazing.
I have no idea how you determined which replacement part number and where to buy. I have two cnc machines that were used to sandblast signs that need new ball screws.
@@EducatingSavvas omiocnc x3-300-usb. One was intact, the othere was stripped but had two stepper motors and three ot four ball threads. I went and got bearings and four m4 cap screws running around town to suppliers. Bought a used Gecko g540 since they are 10 miles from me. The contoller was taken spart for parts but is 85 percent there. Had advice to build the Gecko and not waste time on Chinesium controller.
The ballscrew is fixed from the other end. The other support which I didn't use, doesn't fix the screw as it allows for linear movement. Anyway you'll just have to wait for the next video for the accuracy test.
Educating Savvas Accuracy is not the issue, it’s the force you put to the motor shaft. That’s why you want to put the coupler behind a fixed bearing. You are headed to a possible broken motor shaft. Don’t believe me? Look it up for yourself. There’s a reason why these bearings exist. You want the fixed bearing on the motor side and the floating bearing on the opposite side. All you have to do is a little research. I’m not trying to make you look bad, just trying to save you some trouble.
Lasse Langwadt Christensen Very little load on the stepper? How about no axial load on the stepper? That’s how it’s supposed to work... no load on the stepper with a fixed bearing at the stepper end...
