EstlCam compressing y axis?

LowRider CNC Troubleshooting
1

I ran my “first” cut on our LR3 w/ FluidNC today. I say first, because my son has a windows based fusion workflow that he’s had success cutting things on our LR3.

The cut was supposed to be a square with a figure inside.

Designed in Rhino on a Mac, exported to VM (parallels) of Win11 running EstlCam.

X axis cut to scale, but the Y axis is about half of what the total value should be.

There are some squaring issues, but not sure what would cause such a uniform Y axis scaling issue.

Any ideas where to start?

Did proportions appear correct in Estlcam? Can you share the gcode file?

Yes, appeared normal in Estlcam.

Code attached

The gcode looks fine and it is square. I don’t think it’s an Estlcam issue.

That’s both helpful and frustrating at the same time!

I had hoped that there might be a simple issue.

I’ll start driving it in a square to trouble shoot and see what I can uncover.

Thank you for looking at the code Jason!

In FluidNC and Marlin you set the number of steps per mm - how do you do that in Estlcam?

Or could you have a mixture or 0.9 and 1.8 degree steppers?

@CG_Boatbuilder Did you find a solution? I am currently having the same problem. Tried to cut a square and got a skewed rectangle. :slight_smile:

I did! Apologies for not posting, I was going to do a summary of all the lessons learned finishing this project.

In short, I couldn’t recall the last time I had homed the y axis.

As soon as I re-homed the y axis, the problem went away. Thus I now home all three axis if it has been more than ~24 hours since the last operation.

Hopefully this helps?

Open a new post with your issues and machine/build/controller please
