Can anyone help, although my software (Vcarve pro) is set to cut a profile through the material the cnc router is not cutting to the required
depth. The material is 6mm vcarve is set to cut 7mm depth. The router is only cutting approx 3.50mm.
Hope someone out there can help
What is the step setting on that motor? It looks like there might be a problem in either how your driver is set up or in how your control software is. Exactly half the distance request is a bit of point on that one.
What control software are you using.? Like Micheal says it very much sounds like the machines setup wrong.
It's not uncommon for the Z axis to be set to a different number of steps to the X & Y axis in the control software.?
Usually this is because the Z axis screw use's a smaller pitch so requires more steps to cover the same distance. . . . So if for instance your X & Y use 10mm pitch screws and the Z Axis use's 5mm then it will move exactly half the distance of the X & Y for the same number of steps so possibley some ones used the same settings for all Axis.?
Easy 2min fix but first if you can give a few more details on the drives and how they are setup regards micro stepping then it may be better to change the micro stepping at the drive or just change steps setting in the control software.?
If your not sure how they are setup then some good pics of the drives will help along with make and model. Also the control software used IE Mach3, EMC2 etc

If yes has it just done it without any changes to Mach.? By that I mean not changing any motor tuning settings or any thing.?
Can you post the G-code file so can take a look.
Edit: Can you give following details of machine so we can verify steps per is correct.
Thread pitch or turns per inch along with any ratio if geared.
Drive model and micro stepping set to IE 400,800,1600 etc could show on drives as 1/2 or 1/4 - 1/8 etc or 4X 8X 10X
Confirm steppers are 1.8deg (200 steps per rev)

i've set this machine up before and i'm sure the z screw was a different pitch to the x and y. I've spoken to Dinasblu and hopefully sorted it over the phone, if not i'm popping in tomorrow to have a look.
the odd thing is how it changed from the original setting.
