M117 missed, or scripts not completed.

Kulitorum

I had this idea that I could hack the missing Z offset using tfree and tpost script, but it was not working as I wanted.

So to debug it, I added M117 commands to the start and end of all four of them.

But I don't get all the messages.

A typical sequence of messages that I get is:

tfree1
tpost0
tpost0 done
tfree0
tpost1
tpost1 done
tfree1
tpost0
tpost0 do…... etc.

I never get the "tfree1 done" message. So either the M117 command is sluggish, or the scripts are not begin completed.

Scripts here:
tfree0.g:

M117 "Free 0"
M83 ; relative extruder movement
G1 E-2 F3600 ; retract 2mm
M82 ; absolute extruder movement
G91 ; relative axis movement
G1 Z3 F500 ; up 3mm
G90 ; absolute axis movement
G1 S2 X-27 F12000 ; park the X carriage at -27mm
M117 "Free 0 done"
G4 3000

tfree1.g:

M117 "Free 1"
M83 ; relative extruder movement
G1 E-2 F3600 ; retract 2mm
M82 ; absolute extruder movement
G91 ; relative axis movement
G1 Z35 F500 ; up 3mm
G90 ; absolute axis movement
G1 S2 U311.7 F12000 ; park the U carriage at +248mm
M117 "Free 1 done"
G4 3000

tpost0.g:

M117 "Post 0"
M116 P0 ; wait for tool 0 heaters to reach operating temperature
M83 ; relative extruder movement
G1 E2 F3600 ; extrude 2mm
M82 ; absolute extruder movement
G91 ; relative axis movement
G1 Z-3 F500 ; up 3mm
G90 ; absolute axis movement
M117 "Post0 done"
G4 3000

tpost1.g:

M117 "Post 1"
M116 P0 ; wait for tool 0 heaters to reach operating temperature
M83 ; relative extruder movement
G1 E2 F3600 ; extrude 2mm
M82 ; absolute extruder movement
G91 ; relative axis movement
G1 Z-35 F500 ; up 3mm
G90 ; absolute axis movement
M117 "Post 1 done"
G4 3000

Ate you looking at the messages on DWC or on PanelDue? DWC stacks them up, but PanelDue doesn't have enough screen area for that so a new message will overwrite an old one.

Messages on DWC. Not all the messages are coming through.

I have a feeling that messages may be skipped in the web interface if two or more are generated within the web interface polling interval. So try using G4 to insert a delay of half a second after each M117 command.

i did like dc42 says
works good with a small pause
