I load a file and start then router moves to position and dives deep into the material. I am using VCarve Pro and sending to the machine with gsender. My machine is a Longmill MK2 3048. I do not have limit switches. XY set to front left corner and z to top of material (and tried material bed) in VCarve and is where I zeroed with gsender, post processor is GRBL (MM). And since I am a new user here I am not allowed to upload files (yeah, makes sense to me too). With this said, I can surface boards with no issues (surfaceing section of gsender), there is no dust collection at this time, machine and router on separate dedicated circuit that is grounded, using shielded cable.
@Dave_Bama Welcome to the group, Dave.
How are you setting Z0 in gSender?
Does it do this for every file?
It is happening on all files. I am using the paper method on the top of the material.
