ofitselfso / linegrinder Goto Github PK

I am new to this and I found LibrePCB and then found LineGrinder. I designed a simple PCB using LibrePCB and then created the G-Code with LineGrinder. I have noticed that my drill holes are about 1.3mm off on the Y axis. I went through the process of making sure the CNC is calibrated but the outcome still is about 1.3mm off.

Is there a setting that I can set?

I can send you the LibrePCB Gerber files if you would like to make a FileManger template for LibrePCB.

Hi, even though application units are set to Millimeters, I am under the impression that the parameters like IsoCutWidth is still in inches....is that correct?
Thanks for your efforts

Hi, every time I try to add a gerber file that I've generated from Kicad it gives me an error message. The one I am currently trying, for instance, returns:

"Error 800 occurred when adding line 20"

In the logs, I see the following entry:

I tried Linegrinder for the first time, and it looks handy. Especially the manual drill touchdown is a very clever feature.
I used Eagle and the PCB Milling ULP before but switched now to KiCad with the need for Gcode generation.

I encounter issues with SMD pads that are shortcuts in the code.

Generated GCode:

I noticed some touchdowns I have no idea why it is generated.

Overlayed Gcode with Gerber showing the shortcuts:

I tried to change some settings in LineGrinder to workaround the issue without luck.
Also, I tried the Kicad Gerber Export with and without X2 Format enabled.
