I used 60oz steppers for three years, first on the Primo, then on the LR, because I didn’t know I bought smaller ones… So yeah, it does work. I now bought 84oz steppers as well because knowing that mine were less strong than they should have been made me feel inadequate. I am going to put the old ones on the Primo again now (that I also never sold)… The kids need a plotter.
Yes. The Jackpot is more or less a dedicated CNC board unlike the SKR and a cheaper alternative.
I have a list in my build thread: Der Froschkönig - Lowrider 3 in Oldenburg, Germany There you can roughly find what I had to buy to upgrade. If it has a price in the second column it means I had to buy it, no price means taken from the Primo. The screws are bundled together though, I didn’t differentiate them by sort.
Get the tiny screwdriver.
