Remove that stray exclamation point.

M98 P"current-sense-homing.g" ; Set the current and sensitivity for normal routine, per the macro
Can you post the contents of this macro?

This is missing C7.06e-8
M308 S0 P"bed_temp" Y"thermistor" A"Build Plate" T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 0 Bed
if this is a prusa bed then replace B4138 with B4725 C7.06e-8

Here is the contents. Currently I dont think I am using it.

I have made all the above changes and it still goes up after homing.

I don't see anything in there that would cause it to do that. Either I'm missing something or the gcode posted isn't actually the gcode being executed. Can you post a screen shot of your folder structure on the SD card? Sometimes files can get misplaced.
It's only when starting a print that it does this, correct? You can home manually and it will behave correctly, but as soon as you start a print it homes and then continues to go up?
Can you post a video?
Now that you've moved M584 to the right place can you send M98 P"config.g" again?

Hello,
Yes, its only when starting a print that it has this behavior. I can home everything normally. Also, it performs a home before in the gcode before it goes up the z axis.
Here is the M98
M98 P"config.g"
HTTP is enabled on port 80
FTP is enabled on port 21
TELNET is disabled
The other bit to look at that I just found that I had not seen before is this start.g file. I think the issue may reside in here.
Is the start.g necessary?; 0:/sys/start.g
; Executed before each print - BEFORE ANY SLICER CODE IS RAN
; This also loads the heightmap from the system's set filament type directory
; (0:/filaments/XXXX/heightmap.csv), if the heightmap does not exist, it will
; create one, and then save in the filament's directory. The HotMesh macro is

From the start.g
G1 Z160 F300 ; [BLTouch] Last chance to check nozzle cleanliness.
So maybe instead of hitting the estoppel actually wait and see what happens.
-
ok, im the idiot. Thanks so much for the help. the issue was the start.g and me not letting it go all the way up in the z axis. I have a print running thank you all for the help.
-
I should have requested the start.g as well. It's just not used very often by many people. Usually if someone is using it, they know what's in it. In this case it's a received config set which I should have looked more closely at. Uploading the full sys folder would have been my next check.
