Hello there…After doing necessary changes when i crave the simple design like triangle it does crave but then there seem to be so much pressure on X-axis that it start to make a grind sound and the design goes off shape.
What is your feed rate?
1524mm/min - Feed rate
This what exactly happens when it is carving https:/uploads/inventables/original/3X/f/f/ff52a25b7ba3f7ea30e3c012e1718ea3d9fae7e7.mp4
Your V-wheels on the carriage might be too tight. Try loosening the eccentric nuts (but not so much that the carriage “wobbles” on the gantry).
The gShield is notoriusly under-powered. You might also try dropping your feed rate to around 750 mm/min.
The video clearly tell us is one (or both) axis steppers are stalling.
Mechanical binding (like wheels mentioned above), feed rate too fast for the load and/or acceleration values too high.
Since the motors are stalling the controller isn’t in temp protection, so its something of the above.
