Hello
Just had an issue with my mach 3 installation win 7
Machine has been working fine for a good while.
it is using a uc 400 eth motion controller.
the problem is that the x and y axis are not moving at the same feed rate (I think)
for instance if the machine is going to start a cut at 100,100 and it traverses diagonally to that point, it will stop at 90,100 and then zero the z, the g code re references the xy point after zeroing the z and so it then moves the x axis to 100.
Unfortunately when cutting radii it turns them into chamfers!
if i enter g code to move on the x axis, the feedrate goes up and down, both on the mach screen and noticeably on the machine.
If i just jog the machine or ref all home then the feed is stable!
The g code files are the same ones I have been using with no problem.
The machine has no stiff points on the axis either way
In motor tuning x and y have the same velocity and acceleration.
Any ideas

So curiously I restarted the pc 3 times and it seemed to fix itself!

No explanation but let's hope it stays fixed. ;)
