Yes, with truncation turned on, 4 decimal places. That should be enough for mm and inch

GC does have truncation turned on by default, and truncated numbers to 3 digits
past the decimal (digits beyond that are so far beyond the capability of the
hardware that it makes no sense to process them, and they can make the lines
long enough to cause buffering problems)

How about removing the option to turn if off in GC if it makes no sense, at this point, to ever disable truncation? Leave the code there in case in the future it is useful, but just disable changing it.

GC has truncate=0 for a default. Just checked it 
FWIW I run with it off and havenāt had an issue I could trace to this for a very long time. Work on the serial buffer had helped a lot!
Also FWIW, the issue in this thread doesnāt seem to be resolved by truncating the floats to three places.

bad usb cable or interference?
Looks like no Z-Axis is installed, so this could be related to the buffer overflow with manual Z. Either way, With FW/GC 1.03 this should be fixed now.
Did you give it a try?
Havenāt had a chance to try it out, will do this weekend. Also will run the file anyway rather than stopping it to see if it just the circle or the whole cut thatās wack.
