Error with files containing a naked G0 #1183

Problem description

When I try to send a file containing a naked G0 I get the following error: "Error while starting file stream: null"
If the G0 is removed the file sends fine.

Steps to Reproduce the Problem

Here's a short file which causes the error:
%
(TOOL/MILL,0.1,0.05,0.000,0)
(FILENAME: )
()
G21
G90
G0X0.000Y0.000Z10.000

Y15.000
G0Z10.000

G0Z10.000

(END)

If the naked G0 is removed (line 21) then the file loads fine.

G0 still needs info on where to go. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Whitetd, What are you doing with those links ?

Curt999 Here is full info how to use G0 whitch should not be nacked:

G0 Rapid Move
Format G0XxYyZz (This mean G0 should not be nacked).
X,Y,Z = axes on a three-axis machine
x, y, z = distance in incremental units, or absolute coordinates, to which the axes specified by the
receding upper case letter is designated to move.

Purpose Moves one or more of the axes, at the rapid speed, to a specified location or a specified distance away from the current position. Location is designated by absolute coordinates when this command is preceded by the Absolute Coordinate command.

Distance is specified by incremental units when this command is preceded by the Incremental Coordinate command.

A rapid move consists of a move of the X and/or Y axis along the XY plane and a move of the Z axis up or down.

If the Z-axis move is Directed from a lower point to a higher point, it will be executed before the XY move; if it is directed from a higher point to a lower point, it will be executed after the XY move.

Rapid speed is indicated in the .NC file by the Feed Speed command. F commands are ignored by the interface program when Override Program Speed is selected. When this selection is made, the rapid speed specified in Set-Up will be used instead.
Example
G90
G0X2.00Y2.00Z2.00
The first command in this set indicates absolute motion, so the rapid move that follows (line 2) is made to the absolute coordinates (2,2,2). The axes move to a position that is two units away on each axis from the software home.

This been said: This is not an issue.

OK thanks. This file was created by Carbide Create so I assumed it was valid gcode.
I'll ask Carbide 3D why it's using a naked G0 command.

AbySet commented Feb 2, 2019

You'r welcome.
hmmm. then maybe it's supported on different cnc processor but not on GRBL.
Please let us know what they say about it, it may be usefull to know.

Carbide 3D issued a ticket for this and said they would fix in a future version.

AbySet commented Feb 2, 2019

Ah ok, it's their issue then.
Thank you so much.
