Z Axis Plunging too Far at Start

X-Carve Troubleshooting
1

So I haven’t used my X-Carve in a long time. Plugged in a new laptop using Easel to cut a new design.
Everything appears to work fine but when starting, the Z axis tries to start about 1/4" below where it
has been aligned. X-Y are fine and Z appears to be correct after the initial 1/4" drop.

What is causing it to start cutting much deeper than expected?

Check your z axis calibration. There was an update a while back that reset my Z axis and I had the same problem.

How do you check calibration and do the update?
