my name is jun from south korea. when I tried just Easel, I have a problem with z depth is something wrong. I tried to make 10mm depth hole. X carve made 20mm hole. do you know why this thing is happen? I check that jog the machine an inch in the z-axis direction and see if that moves an inch in reality. it works well.
please help
jun
By the way, I use mm not inch
How did you set your Z zero?
What are you cutting? What are your cut settings?
I did z zero
I tried cutting woods and plastics
If the machine goes deeper that intended you either have an incorrect workflow or mechanical issues.
1 - If during Machine Setup you chose Z-plate, this introduce an Z-offset and if you zero on top surface of material total plunge = design depth + offset
2 - Mechanical, loose pulley, steps lost during retraction etc. Do the bit return to the exact starting point again after the carve?
thanks for kind explaination. when I jog z axis, I tried to move 1mm but it was not. it was moved more than 1mm. do you know why?
Jog a 20mm command up and down several times - what is the actual distance measured?
You can affect travel by choosing a level of microstepping and defining a step per mm value (GRBL parameter $102 for Z axis)
What is your current $102 value and what is your Z microstepping set to?
I jog 10mm but i moved 20mm so how can I fix this? can you tell me where is a level of micro stepping set is ?
May I suggest you search the forum a little also? Research and then ask if required

yes, you need to adjust $102. Basically, you need to use a ratio of the input movement and the actual movement. So if it moves 20mm actual on a 10mm input, you need to use a .5 ratio, which would decrease the actual movement to the input movement of 10mm. Hopefully that isn’t too confusing, but that is a very basic boiled down version of what you need to do.
Basically, you need to calibrate your machine.
Yup.
Changing the micro stepping value one can also tweak the steps/mm in halves and doubles.
What is your current $102 value?
