Scaling Error

Post by Cattmy » Fri Jun 26, 2015 4:55 am


I picked up my TinyG this morning and got it set up with Chilipeppr with no trouble.

To test my machine I'm using a sharpie to plot some text. The problem is Chilipepr says it will be about 61.09mm wide but it plots it so it is about 241mm, approximately 4x scale.

I'm not sure if this is a Chilipeppr or TinyG problem. Perhaps its a setting in the TinyG I messed up.

I am using the OpenBuilds lead screws and NEMA 23 steppers with all axis.

Any guidance is appreciated!

This sounds like a settings error, what info did you use to guide you thru setup?
A good starting point is the tinyG wiki, ... rsion-0.97

Scaling issues usually have to do with travel per revolution settings, $xtr, x=1 to 4.

I am not familiar with the machine you are using, so you may have to explain why you set to a particular value.

It is often helpful if you copy your settings to a cloud folder and post a URL so we can see what you have.
