I made a bunch of wood flags, and I am putting notched out holes in the back of them. I was curious, is there a way in reptier host to send my router to, say, x 152.4 y 250 z 10 without having to click the arrows over and over? Like, just type whatever the code is?
(The bit I am using is one of those router bits that you would drop down 8mm into the wood, then go Y +10mm, Y -10mm, then lift it out of the wood so it will hang on a screw sticking out of a wall)
Thanks in advance for your help!
Yes - under the manual tab you can enter the co-ordinates you want the cutter to go to with a rapid move command (G0) and then issue a cutting move command with a G1…something like
G0Z10 ; to lift the cutter 10mm
G0X152.4Y250 ; rapid move to the correct location
G1Z-18 ;move the head down 8mm into the wood
G1Y10 ; make the Y cut
G1Y-10 ; move the cutter back to the entry point
G1Z-18 ;lift the cutter 10mm clear of the workpiece
G0X0Y0 ;return the cutter to the origin (or home)
Mike is right, but you haven’t put any feedrates in. Marlin also doesn’t treat G0 and G1 any differently. Here is a docs page I wrote that will help:

You can also make macro buttons for common gcode. But the send gcode input works.
And you’re mixing relative and absolute coordinates.
G1 Z-18 will move down to Z=-18 if you are in absolute. G0 X0 Y0 won’t do anything if you are in relative.
I ended up opening an existing gcode file and editing the x y and z coordinates to match what I needed. I have like 30 of these dudes to finish and have now shortened my time to do this from a few minutes to under 30 seconds 
haha.
