UGS error "Multiple points" and "for input string "-""

I do not know why I have to reset UGS when I run a file then try to load up my other file for running it throws these two types of errors and I can’t find anything on google that suggests what I am doing wrong.
Any clues?

Found the problem.
In the g-code it has a space between the - and the number.
example: G91 G0 Y- 15.875
There should be no spaces there.
this is the correct code: G91 G0 Y-15.875

I calculated this using Charley’s spreadsheet.
I then copied and pasted it into a text file.
For some reason it has a space but if you look for it and remove it then it works without this error.

Is this one of those cases “You get what you paid for”?
It seems there is a lot of problems lately with UGS’ builds but it is free.
Not sure if free is worth the headache.

The problem was not UGS
It was the gcode.

I still need more work for this machine to work right.
I have those TB660 modules hooked up to the Arduino like you have in your diagrams.
I just need to get it rewired with some shielded wires and make a proto board so everything is tight and solid connections.
I need a better controller. I want to move away from the arduino and get something that is common and not too difficult to use.

Where do you get the noise filter?
