Dimensions changed 50%, drawing to effective cutting

I have entered a drawing of 100mm x 50mm in the estlcam, perfect everything fine. Then exported to the estlcam controller, it is grbl arduino. Now that I start engraving the drawing is cut out for 50%, so 50mm x25 mm.

How is that possible?

Did you import it into estlcam under the same units as your CAD exported? If you did your drawing in CM and imported as MM (or any other variation) it can change things.

Hi, everything in mm. The different is exactly 50%.

Well that’s a new one for me. Hopefully someone else has ran into that before. That was my only idea for this one.

Has this ever worked correctly?

Sounds like your steps per mm are halved in your controller.

No, never has worked proper. How to check this, I am a new bee, and I want to fix.

I’m not familiar with Estlcam or the Estlcam controller, but I’d be surprised if this (steps per mm) wasn’t the cause.

Essentially, you need to send some commands to the controller at a console prompt.

Send the command $$ to get the current settings.

$100 is the steps per mm for the x axis. $101 for y, and $102 for z.

Double the values (at least for x and y) by sending commands like:

$100=200

and

$101=200

…where 200 is the value you want to set (which apparently needs to be double whatever it currently is).

Thank you, I will try tomorrow and let know the results .

@Tokoloshe If he is using Estlcam controller then this is all you :rofl:

If he does, sure. :yum: I’d guess wrong steps configuration.

It seems like an impossible task to calibrate this in the estlcam environment, the deviation for X 0.65% Y0.42% 

Reverting to old firmware also doesn’t work, so I’m stuck with estlcam.

NICE!

im not familiar with estlcam boards but you can try the lightburn e-steps/axis calibration, it should be able to write to the arduino.

Which old firmware? Estlcam does not have old firmware? You need to be more specific.

Which controller do you use? Which board?

Don`t restore original controller arduino.

That still does not make any sense without the context. Are you programming it via Estlcam?

yes OfCourse

And why does it fail? Did you try plugging the cable in/out?

Try to double the steps per revolution on the axis that is too short (or was it half)?

Done, 3 axis calibrated 100%. Its are not the problem of the steps, but distance. You have to degrees this. And thats logic !

Okay, what was the solution?
