Hello community,
I have purchased a CNC 3018 pro, when I connected the machine to the computer and used Candle, the machine moved on the X Axis (Up and Down) just fine, when I told the machine to decend 10mm it did and perfectly, after connecting easel and it wrote the configuration it messed my machine up, when I tell the machine to move the spindle 10mm down it only does 1.2mm down and up. I thought it may be a board issue as no one else has reported on this so I purchased a new board, worked fine again UNTIL it wrote the config again and now I am stuck with another semi-broken machine. Does anyone know the correct settings I should be using, at the mo I thing i’m using: grbl (Other) > Arduino (GShield) > Rail Size of 500mm x 500mm > ACME threaded rod > 24V DC spindle and no dust shoe. If anyone knows how to reset the board so it works again with Candle doing 10mm when I tell it to do 10mm would be much appreciated and I will just start exporting GCode from Easel.
Many thanks,
Charlie
In Easel, open Machine Inspector and in the Console window write $$ and press Enter
A full list of your GRBL parameters will show, take note of value $100, $101 and $102
$100 = X axis (left and right)
$101 = Y axis (back and forth)
$102 = Z axis (up and down)
You need to recalibrate these three values, check this video for reference:
Changing the GRBL parameter is simple enough:
In Console window just write the new value like this $100=xxx followed by Enter
So how to I reset the value in machine inspector, eg. change it from the 188.976 to 1600.000
In Console window just write the new value like this $100=1600 followed by Enter
You may need to restart the controller to make the change come into effect.
It may require fine-tuning to get maximum accuracy out of your machine.
You are a life saver, nearly had to buy another board!!! Many thanks
No problem, glad it sorted your issues 
The reason for your troubles are that the parameters provided by Easel set up assumes a specific setting of microstep levels and distance per revolution. For the CNC3018 these are different hence the…difference 
So by putting in the corrected values for the key parameters, in this case the step/mm value for each axis, you are good to go
I recommend you write down (or screen shot) your correct GRBL parameters in case you need to reflash at a later time.
PSA:
If you don’t have an X carve, don’t run the machine setup in Easel.
Lots of these recently.
