Newbie here, just got an Openbuilds 1010, black box controller. I drew a grid pattern in Easel with 2" centers using the replicator app for a waste board…when I ran the job, the actual pattern came out 2-1/2" x 2-1/2", unsure why. Then I down loaded the drawing for some material hold downs that were drawn in Easel, they should have been 5" in length as show on the layout, they cut to 6-1/4" long. Is this an Easel thing, is it the cnc or is it me?
Most likely incorrect step/mm values for your X/Y/Z axis.
(GRBL parameter $100 for X, $101 for Y and $102 for Z)
Take out a ruler, a fine bit or V-bit and measure how far each axis move by commanding a jog.
Command say a 100mm jog, what is the actual travel?
Measuring over the longest distance possible give you the most precise numbers for re-calibration calculation.
To find your current GRBL values (The rules the controller follow) open Easel, press CTRL+SHIFT+D to open Machine Inspector window (MI). In the Console type $$ and press Enter.
A list of GRBL parameters will be listed below, running from $1…$134
If you report back your commanded vs actual movement values and your $100-$102 parameters we can assist you with the math. Its not complicated, but can be overwhelming for newbies. We have been there
Welcome to the forums
This thread addresses it pretty clearly.
This worked out great!..thank you for the info
