Hi All,
I got my Longmill 12x12 6 months back. I put it all together now, it seems to be working great on the X and Y-axis perfectly, but not on the Z-axis. It seems like whenever I run my code the cuts never go down to the depth I want and afterward if I click on “Go to Zero Z” it never goes back to the right height.
Not sure what kind of software issue can cause this?
I thought this might be because of a hardware problem. So I made the CNC cut in the air, after completing the cut I checked the Z zero height, it seems to be wrong. I thought it might be some kind of issue is the setup or wiring which is causing the Z-axis to slip. So I made the ZYX move randomly by clicking in the control panel. This time it seems like Z returns to proper height when I press “Go to Zero Z” .
Does anyone has any idea on how to fix this issue.
Thanks in advance
Victor
@victor Welcome to the forum! I am positive someone here will be able to assist you with your difficulty. You could also contact Sienci directly. I am sure they would assist you as well. Me, I am just a “patiently waiting “ person. Meaning I ordered my unit and awaiting its arrival.
Please take a minute to post the solution to your problem. It may help other users too.
@victor Check to make sure your bit when installed in the router can reach the surface of your spoil board. Your Z may be bottoming out during the cut which would mess things up pretty well.
I would also make sure all of your connectors are tight on the coupler to the Z stepper motor , the belt from the stepper motor to the lead screw at the top of the Z Axis is tight as well.
Finally, make sure your bit is securely in the collet (tightened with the two wrenches, not using the push button) and not slipping when cutting.
That sounds like loose connectors either at the stepper motor/lead screw coupler or the belt to stepper motor isn’t tight enough. I am sure others may chime in with more hp.
@victor Welcome to the group, Bir. As you’ve already seen, it takes not time at all for members here to jump in to offer help.
If I understand, you can use the GUI to jog all axes and when you return to zero, everything is fine. However, when you run gcode, even when cutting in air, Z does not return to 0.
Can you tell us what CAD/CAM software you are using? What post processor are you using in that software? Can you post gcode where the problem is showing up?
