G0/G1 issue after tool change
-
Hello,
I'm using a DuetWifi with the latest firmware 2.02 to control a CNC router. I have found the following issues after a tool change using G0/G1 commands.
T0 ; select tool 0
G0 Z50 ; move to position Z50, position shows Z50
G10 P0 Z0 ; set tool lengths of tool 0 to 0
G10 P1 Z10 ; set tool lengths of tool 1 to 10
T1 ; select tool 1, position still shows Z50 instead of Z40
G91 ; go to relative positioning
G0 Z0 ; no movement is expected to occur however Z moves down 10 and now correctly indicates Z50
T0 ; select tool 0 again, position shows Z50 instead of Z60
G0 Z0 ; again no movement expected but Z moves up 10 and again correctly displays Z50It seems that the Z position is not updated after a tool change and with the first G0/G1 move the difference is noticed and compensated by an according move. I think this behavior is wrong and potentially dangergous as it leads to unexpected Z-movements.
Regards,
Marc
PS: ...unconventionally for CNC tool lengths have the opposite sign i.e. a shorter tool has a greater tool lengths. Not really an issue but something to get used to...
