Surprise, surprise I am having issues with this machine. Seems like I’m not the only one. First off, hi everyone! I’m new to the forum and new to routing with cnc. I’m a waterjet operator so have some experience with cnc. But anyways, my carvings are coming out much, I mean much larger than designed, I designed in freecad, and in easel. Both resulted in the same problem. I checked to make sure my designs were in inches, candle is set to inches, and made sure my post processing save settings are to grbl. If anyone has any ideas on how to rectify this dumpster fire of a machine that I’ve been trying to get going for almost a year now, I would be forever grateful.

It actually sounds like it was designed in mm and you are using an inch postprocessor. 25.4 mm is changed to 25.4 inches. Does that sound like what is happening?

I can’t say no for sure. But I double checked all my designs and they are all in inches. Unless the post processor is converting it to mm. If that is the case I have to do some digging to see how to correct that

Yes if the project is designed in inches then you use a mm post-processor then everything will be very small when cut. That is why I questioned if it was designed in mm then an inch post-processor was used.

If you are designing in inches and you are using an inch post-processor then I would say the settings are off. As David said it needs to be calibrated. Here are two links to videos that will explain what you are needing to do, but they are Mach 3 based. I'm not sure what these would relate to with your machine but I think you need to calibrate your machine.

Awesome! Thank you sir, I will check it out and let you know what I find out.
