Here’s what I’ve done so far. I got the honking big 114mm 425oz.in/3Nm stepper and installed it on my z-axis with my existing 65mm spindle. Everything seem to work fine without any other changes to software or my set up. I thought it might be a little overkill but hard to tell until I get the heavier spindle installed.
I started thinking about the weight differential (Not only the spindle but whatever larger stepper I put on the Z axis) And thought that upgrading the other steppers might be a good idea as well considering that the Y-axis would now be carrying all the weight of the increased package. So I bought a bundle of 3 269oz.in/1.9Nm steppers.
The spindle mount came yesterday and today is my reconfiguring day.To start, I’ll be just upgrading the Z-axis spindle stepper to one of the 269 oz steppers and see how that does. Over time I’ll upgrade the X and Y steppers as I have time.
Here’s a photo of the three different stepper sizes and the 65 and 80mm spindles. On the left is the original stepper, then the 269 then the 425.
I’ll let you know what I find out.
