Print starts without heating the nozzle

Post by Fred1 » Sun Jan 21, 2018 9:13 am

Hi guys,
I've got my I3 Pro B in December, so I'm still a dump newbie.
I ordered a 3D touch and got it run ( after a lot of reading and try with the Firm Ware )
Using Marlin-PI3_Pro_B_3DTouch (A+) FW. Board 2560 REV A+
First print I realized that my nozzle is not low enough and the pin of 3D touch was hitting the print. I departed before
Ok after resetting all, had a lot of issues to set the Z offset again, but that's done now.
( I had to flash first an older Fw then, the right one to get some changes ---very strange to me )
Any way now is my problem that the print doesn't start because the heat setting are both on zero ( visible on the LCD ) it comes heating up but .../0
Here is my start code:
;FLAVOR:Marlin
;TIME:4511
;Filament used: 2.37263m
;Layer height: 0.1
;Generated with Cura_SteamEngine 3.1.0
M190 S50
M104 S195
M109 S195
M82 ; absolute extrusion mode
G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
{IF_BED}M190 S{BED}
; Activate all used extruder
{IF_EXT0}M104 T0 S{TEMP0}
G92 E0 ; Reset extruder position
; Wait for all used extruders to reach temperature
{IF_EXT0}M109 T0 S{TEMP0}
M107 ;start with the fan off
G28 X0 Y0 ;move X/Y to min endstops
G28 Z0 ;move Z to min endstops
G29 , AutoLevel 3DTouch (BLTouch)
G1 Z15.0 F9000 ;move the platform down 15mm
G92 E0 ;zero the extruded length
G1 F200 E3 ;extrude 3mm of feed stock
G92 E0 ;zero the extruded length again
G1 F9000
M117 Printing...
;LAYER_COUNT:310
;LAYER:0
M107
G0 F3600 X73.906 Y89.919 Z0.3
;TYPE:SKIRT

Maybe the firm ware is wrong as well
Has anybody an idea what's wrong
Thanks in advance Fred

You can try to change"M104 S195" to "M104 T0 S195"
"M109 S195"to"M109 T0 S195"

Hi William, thanks for your answer, I fixed it my self.
I use now i simple start code:
;FLAVOR:Marlin
;TIME:7707
;Filament used: 3.54472m
;Layer height: 0.1
;Generated with Cura_SteamEngine 3.1.0
M190 S60
M104 S195
M109 S195
M82 ; absolute extrusion mode
;FLAVOR:Marlin
M190 S50
M104 S195
M109 S195
M82 ; absolute extrusion mode
G21 ;metric values
G90 ;absolute positioning
M107 ;start with the fan off
G28 X0 Y0 ;move X/Y to min endstops
G28 Z0 ;move Z to min endstops
G29 , AutoLevel 3DTouch (BLTouch)
G1 Z15.0 F9000 ;move the platform down 15mm
M82 ;set extruder to absolute mode
G92 E0 ;zero the extruded length
G1 F200 E3 ;extrude 3mm of feed stock
G92 E0 ;zero the extruded length again
G1 F9000
M117 Printing...
;LAYER_COUNT:590
;LAYER:0
M107

that's working now, only my end code seems to be still wrong or something missing.
The issue is after finishing a print the extruder is not moving down in z direction correctly it is only in 0 position x and y.
when I start another print from this position the moving in z stops before it reach the bed so it will print in air.
So I have to do home position via LCD before I can start a print.
Here's my end code:
M107
M104 S0 ;extruder heater off
M140 S0 ;heated bed heater off (if you have it)
G91 ;relative positioning
G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure
G1 Z+0.5 E-5 X-20 Y-20 F9000 ;move Z up a bit and retract filament even more
G28 X0 Y0 ;move X/Y to min endstops, so the head is out of the way
M84 ;steppers off
G90 ;absolute positioning
M82 ; absolute extrusion mode
M104 S0
;End of Gcode

Use G1 Z+15; move z aches to 15mm, after G28 would be right?
Ok, I can start always a manual home but maybe you know a way to change the end code.

Now I wanna ask you about my main problem, is my Auto Touch already broken?
After about 5 minutes print the Touch is blinking and short after that the pin is coming down and hit the print.
the nozzle offset is set to -1.00mm and the brim and first layer is set to .3 mm the layer looks ok.
Hope you understand everything English is not my first language.
Thanks Fred
