Hi Guys,

Strange behavior when trying:

PC - win7 64  
UGS -Nightly 2.0 23 April 2017  
Java - JRE-8U131 windows x64

Did setup the probe dimensions in mm, got the G-code, homed UGS - all ok. Moved the 3 axis to probing starting point, hooked the clips (I have 4.9 Volts between them) and when fetching the g-code even before sending it - I get an error message:

When trying to get on with it - I get some weird Gibberish symbols:

Loaded another G-code from another source - no issues !

The Gcode generated by Triquetra is:

G21  
G92 X0  
G92 Y0  
G92 Z0  
G38.2 X-12.7F50  
G92 X51.5875  
G91 G0 X12.7  
G91 G0 Y25.4  
G91 G0 X-25.4  
G38.2 Y-25.4 F50  
G92 Y51.7875  
G91 G0 Y3.175  
G91 G0 Z‪25.9‬  
G91 G0 Y-‪15.875‬  
G38.2 Z-25.4 F‪76.2‬  
G91 G0 Z‪1.27‬  
G38.2 Z-‪5.08‬ F25.4  
G92 Z2.5000  
G91 G0 Z3.175  
G91 G0 x25.4  
G91 G0 Y25.4

To me it seams either the Gcode is missing something, or my UGS has a parameter which creates that, or perhaps the Jave ???

Anybody had this problem ?

Many thanks

Isaac

@IsaacNeuman you seem to have some invisible/extended characters in your program. Copy/pasting the program above into a new plain text file should resolve the error.

Don’t worry, you’re not the first to run across this: [An error was detected while sending (only on nightly builds) · Issue #603 · winder/Universal-G-Code-Sender · GitHub](https://github.com/winder/Universal-G-Code-Sender/issues/603)
