My goal is to provide the Teensy with a set of values generated from a graph, allowing the stepper motors to independently perform a precise number of revolutions (outwards or inwards). The three motors must complete a different number of revolutions, but they will stop at their...

Is there a way to reverse one in the software or does it need to be reversed mechanically.?

The main factors in making a machine go faster are cutting power (a mix of steppers and milling machines/spindles) and the rigidity of the machine. It seems that when using 76 oz-inch stepper motors, machine speed is limited to around 10-15 mm/sec with a DOC of about 1-3 mm (very material dependent). If you go...

I have been working on a custom PCB prototype & I am encountering an issue where certain connections intermittently fail; especially when the board is slightly flexed or after prolonged operation. I've double-checked my solder joints and reflowed some suspect areas, but the issue persists. The problem appears to be more prominent when the board heats up or is under minor mechanical stress.

I’m wondering if this could be due to microfractures in the PCB...
