Tool offset Z ignored
-
I tried this, and that made no difference:
[init]
….....
; layer 1, Z = 0.18
T0
G91
G1 Z0.01
G1 Z-0.01
G90
; tool H0.200 W0.480
; skirt
G1 X128.035 Y135.490 F9000
G1 Z0.180 F1002
......
G1 X141.305 Y158.772 E4.7989
G92 E0
G1 E0.0000 F600
; layer 2, Z = 0.18
T1
G91
G1 Z0.01
G1 Z-0.01
G90
; tool H0.200 W0.480
; inner perimeter
G1 X139.180 Y159.180 F9000
G92 E0
G1 X130.820 Y159.180 E0.3003 F1628
G1 X130.820 Y150.820 E0.6006
.........Any ideas for a workaround?

And now I am doing this, which still does not work:
G90
M82
M106 S0
M140 S60
M190 S60
G28 ; home all axes
G10 P0 R210 S210
G10 P1 R210 S210
M104 S210 T0
M104 S210 T1
M109 S210 T0
M109 S210 T1
G28
G92 E0
G1 E-1.0000 F1800
G1 Z1.180 F1002
; layer 1, Z = 0.18
T0
G1 Z0.180
; tool H0.200 W0.480
; skirt
G1 X128.035 Y135.490 F9000
G1 Z0.180 F1002
….................
G1 X141.305 Y158.772 E4.7989
G92 E0
G1 E0.0000 F600
; layer 2, Z = 0.18

G1 Z0.180
; tool H0.200 W0.480
; inner perimeter
G1 X139.180 Y159.180 F9000

Am I doing this right - this is what you ment, right? - With the G1 Z# after the tool change?
-
I just realized - the displays claims that the z position is 4.6 when printing with the second head, but the printer is not at z4.6. Again - the firmware seems to think it is at 4.6, only it is not.

This is worse even….
Turns out that if you set offset Z for tool 1 to anything other then 0, that head is always printing at the same z position as the first layer. In my case 0.18mm. So every layer is printed at z=0.18m. At the same time, the displays will always show the Z-offset value, so the display in my case always shows 4.6, but it always prints (every layer) at 0.18.
I fixed it with a metal file. My z-offset is now 0 and that works better.
BTW, OffsetX is also not used. So I had to calibrate the U axis in homeu.g

Hi i build a machine with dual x carriage and i had the same problem.
what you need to do after a tool change is add G01 Z[current z value] (in absolute coordinates) and it will work fine.
i made small script that does this for me. it would be great if we could add
this in the toolchange files
with a variable for the current z height -
If you look at my last gcode, is that not exactly what I am doing?
Maybe you can post an example gcode? - or parts of it?`
Thanks.
-
Is there any progress on this?
Is it fixed in 1.19?
-
having same problem any update ?
-
Thanks for reminding me. I'll fix it in beta 7.

Great! Looking forward to it
