Strange movement behaviour in tfreex.g files

illy

Hi everyone!

I have just upgraded my firmware from RRF 3.0 to 3.1.1 and found out that there is a strange movement in the tfreex files. It moves upwards after the last G1 Z-2 command in the tfreex.files.

tpre0.g

M400

G91
G1 Z2
G90

G1 X-30 F12000
G1 X-39.5 F1000
G4 P300
M280 P0 S155
G4 P300
G1 X-30 F12000

;G91 ; commented out, the user Z coordinate is restored immediately
;G1 Z-2
;G90

and this is the tfree0.g

G91
G1 Z2
G90

G53 G1 X-30 F12000
G53 G1 X-39.5 F1000
G4 P300
M280 P0 S60
G4 P300
G53 G1 X-30 F12000

G91
G1 Z-2
G90

I look forward to your help. Thanks!

I've also tried with a M400 command but it did not help me.

Is it cancelling the Z offset of the tool being freed?

@dc42 I think yes. The Z offset is 0.89 mm. This is the code in the macro file:

G10 P0 X-32.85 Y-2 Z0.89 L1

@dc42 it also happens to the tprex.g files, but it moves downwards after the last G1 Z-2 command instead of upwards. Is it because of the Z offset that being applied and cancelled after a tool change?
