Y Axis issue

Take a look here:

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…

X-Carve Maintenance/Troubleshooting Videos - Add Your Own!

There are a lot of repeated questions and answers on here, and some good videos that explain everything. I’ve got 2 maintenance and one X-axis stiffening video that I made that may help with some X-Carve maintenance and troubleshooting. Since a picture is worth a thousand words, videos have got to be worth a few more. If you’ve got a video, or like a video someone else has, put it up on here. Let’s make a collection that will be easy to reference for various X-Carve users!
