Endstop issue - stopping delay
-
I have an endstop issue.
I have a Makerbot clone (CTC) and have replaced the control board with a Duet WiFi.
When clicking on XHome head moves ok; upon pressing the endstop with my finger I can see the x movement actually increases slightly, and carries on for about 7mm, then stops.
If I leave the head to track across it crashes into the endstop.
The endstops seem to work ok, in that LED illuminates on duet when pressed.
I suspect I am missing something in my code!HOMEX.G

One thing that leaps out at me is that you don't move away from the end stop, you move further towards it. You have this….....
G1 S1 X-280 F400 ; move quickly to X axis endstop and stop there (first pass)
G1 X-5 F600 ; go back a few mm
G1 S1 X-233 F400 ; move slowly to X axis endstop once more (second pass)That second line should be
G1 X5 F600That is to say, take out the minus sign.
