MPCNC Issue - Slow Steppers

#1
I recently upgraded my firmware to the latest version (Arduino board). Since then I did a lot of laser work and some engraving and everything worked great. The laser code was out of Inkscape or PicEngrave Pro, the engraving was ESTLCAM 8.5.
I installed ESTLCAM 11 to give it a try and now my steppers (X and Y) are behaving strange. They are running, but at an extremely slow rate and pulses vs smooth motion. The Z axis is fine. I tried an older file that was done in 8.5 that I have done before and that is not working either. Below is a sample of the G-Code.
Thoughts?

I would check hardware first...

First ensure that you are getting enough voltage to the steppers (60% of issues I've had can be traced back to this) this includes maybe the power supply and increasing the pot on the driver board a bit.

Second check that the drivers are not overheating (this can cause lost steps.)

then check for a physical reason (binding) is it always in the same place a single or both axis?

are you running 12 or 24V?
Board make.

The reason I suggest this is (unless things are just SERIOUSLY wrong with that release, I'm running V10.038) no-one is going to change the format of G-code output. And the fact you say now older G-Code file fail as well.

My guess is maybe you just have a belt loose or something causing some friction and the motors don't have enough voltage to overcome it.

(Edit)
Do you have a spare board? Maybe something went wonky as you flashed it... (just one more thing to try...)
