Using a GShield and having bit of a weird carving issue. Tried sending file using GRBLcontrol, candle and Universal GCode Sender- all have the same issue.
Heres my file loaded up in grblcontrol:

Here's what it carves:

Note the screwed up letter spacing and errors on the K
Any ideas? I'm assuming one of the motors/something on the GShield is fried?

I think you are cutting with high speed.

try to cut with very low feed rates

Looks like it's not directly connected with actual cutting but with rapid moves between cuts, it's possible that acceleration is set too high so steppers are stalling. But I assume that it's not your first try at milling so it's wise idea to think what has changed.

Check your max feed rate when your code is issuing the g00 command it looks like your stalling out. Anytime G00 is issued it always uses your max feed rate.

$110	Configuration	x max rate, mm/min
$111	Configuration	y max rate, mm/min
$112	Configuration	z max rate, mm/min
