resuming g-code

[-richard- 0]

Hi, I have a large print that I want to pause because I don't want to leave my printer running unattended.

It stopped at layer 100. Now I would like to resume it at this layer the next time. I was thinking of just deleting the first 100 layers from the g-code and running the rest, is this possible?

The first commands at layer 100 look like this:

;LAYER:100

;TYPE:WALL-OUTER

G1 X73.206 Y124.307 Z20.2 F9000.0

G1 X20.861 Y23.532

G1 X20.069 Y20.68

will this instruct the printer to start at Z position 20.2, without "homing" first?

Also, should I change anything to the g-code start section?

thanks!

I would keep the start code intact, and then delete everything up to layer 100
