Z height problems

This has been covered somewhat but I cant find my exact issue. I’m using Careveco for my projects and every time I start a project with gsender the z automatically goes to its hard limit and I have to stop the job. I have adjusted all the settings i could find. pleases help

@bamafan55 Welcome to the group, David.

  1. What CNC machine are you running?
  2. If it’s a LM, are you using the SLB or the LB to control it?
  3. What version of gSender are you running?
  4. Before you starting using gSender, was your machine running properly?

Do you have a G28 command at the start of your gcode? 99% of the time it’s related to postprocessor setup.
