Hi, after a while (will be a year probably) i’m again preparing some milling for my cnc. I generated the gcode and have seen there is the “A” postion as well in the code and in all my code as “ANaN.0”. I wonder is this a valid code or i’m missing some settings for the “A”, or to disable? I did not try the code on the router yet - asking in advance. G21 G90 G0 X56.5413 Y126.2218 F4000 G0 Z5.0 ANaN.0 F400 G1 Z-0.3236 ANaN.0 F150 G1 X57.1046 Y125.9740 ANaN.0 F1600 G1 X57.6778 Y125.7511 ANaN.0 G1 X58.2601 Y125.5534 ANaN.0 Tnx for the advice ---

Can you export and upload your workspace? It seems you have a missing or invalid value somewhere that is causing a NaN (Not a Number) error in the coordinate calculation. ---

I’ve been using my CNC router all week, and then today have started having the same problem - despite all settings remaining the same, all my G-code is now being exported with ANaN on every line. It also stops the code from running. ---

Could you try reverting to the previous version and exporting the g-code and see if it still happens? ---

if you use `files --> export` to produce a `.kmz` file and email it to me I can take a look … [sa at grid dot space] ---

Hi Daniel, I’m tracking down a bug in the CPU based contouring code that seems to cause this. In the meantime, please try enabling GPU acceleration since that uses a new code path for contouring that doesn’t have this issue. ![Screenshot 2025-12-22 at 9.57.28 AM](https://forum.grid.space/uploads/default/original/2X/e/e622dfa758612515392cb2ba124b19a987c46bc2.png) ---

Hi Stewart, Thank you very much for the information. It solved my problem. 🙏
