Positioning Errors One of the most asked about troubleshooting problems with a new X-carve is positioning errors. Almost all positioning errors are corrected by adjusting the various parts of the machine. Very few of the problems are actually due to failing components. The X-carve is a very flexible machine and so one answer cannot fit all situations. Each person will use their machine in a different way which makes it difficult to precisely quantify each adjustment. Positioning errors are alm…

Setting the stepper motor current limit

The potentiometers on the gShield are setting the Vref (Voltage Reference) level on the TI stepper motor driver chips. This determines the current limit for the driver. You can measure this voltage at one of the potentiometer pins (see photo) and adjust it to obtain a given current limit. Use great care as the potentiometer pins are very close to other components and it is easy to short the pins together with your meter probe. Really bad things happen. The gShield (version 5) uses a 0.1 ohm cu…
