G30 S-1 Crash After Probe Sequence
Has anyone seen a machine crash following a successful probe sequence?
G1 X400 Y400 Z5 ; move to middle of bed
M401 ; deploy BLTouch
G30 S-1 ; Probe point
Following the G30 S-1 the machine drives back to X0 Y0, but ignores the end stops and collides into the hard stops.
Any info on what I may be doing wrong?
Do you have that sequence coded in a macro file? The reason I ask is that I don't think it's that sequence that is causing the crash, it's whatever follows it.
The M401 command is not needed unless you are either using pre 1.19 firmware or you want the probe to remain deployed after the G30 command.
No macro. We are manually moving axes to those positions. When I try to perform just the G30 S-1 the probe does not deploy which is why I added the M401. There shouldn't be anything after the G30 S-1 as we are sending it through the touch screen.
Which firmware version are you using, and what do you have in your retractprobe.g file?
Firmware version 1.19.2
M564 S0 ; don't apply limits
G1 Z40 F10000 ; raise head
G1 X-59 Y66 Z35 ; move over the post
G1 Z7 F500 ; push probe down on post
G1 Z35 F10000 ; raise head again
G1 X0 Y0 ; move to somewhere sensible
M564 S1 ; apply limits again
This is where the problem is. I need to update this script to what I had in my previous script prior to updating to 1.19 from 1.18
