The board features several onboard micro-potentiometers used to fine-tune operations. These come calibrated from the factory, but swapping out a motor or control board requires minor recalibration: : Intercepts oncoming current spikes; typically utilizes a
A heavy-duty bridge rectifier converts the AC voltage into raw, unregulated DC voltage.
: Variable returning voltage determined by knob position. Low (GND) : Reference ground. 4. DC Output Stage If you share with third parties, their policies apply
: Suppresses transient voltage spikes coming directly from main shop lines to shield delicate rectifying components.
If your lathe has stopped spinning or runs only at full speed, check these common failure points:
