Extruder heater disabled when print commences and ETA is -8 sec??

rcrocket33

I recently went into repetier and tried to print something. I noticed that when it homes, it travels to its designated position and then extrudes a set mm of filament as I edited in the Gcode. Once it gets done, it disables the extruder and does not print.Also, before I even go to print, The estimated printing time is -8 sec?

Repetier

Have you checked the log? Ignore time estimate, it is just a prediction that can be wrong at the end. More intersting is why it does not print. Does it still handle commands or even move?

rcrocket33

Yes it still handles Gcode commands and it still moves. I heat up the extruder and load my part I want to print. I then press print and it homes then travels down to 10mm above the bed or something as it always did to make sure the extruder temp was still acurate. But then this is where the extruder shuts off??

Repetier

So maybe it is the extruder causing a error, which is why I said to check the log. You get a message there if firmware thinks it is decoupled/defect and disables heaters.

I did check the Gcode and everything seems okay. I attached a copy of my Gcode to see if you see anything fishy. It is the first 30 lines.

M666 is used to force communication error for testing, no idea what you want to achieve here.

M104 does not wait for temperature and M109 is missing.

But as I said check the log!

What firmware are you using?

rcrocket33

I used m666 because me bed is unlevel. My auto probe does not work so I used m666 to in a sense make my bed level when the m666 is put into play. My EMPROM is disabled so I figured I could include the m666 i the start Gcode? I guees my question is if I can't use my m666 command in the start up gcode, how can I have the endstop offsets? I am using Marlin firmware. I will check the log

What do you think of this? I left the m666 in there because I figured I should leave everything the same as before and let you see it.

So you are not using repetier-firmware as I understand.

Host does not disable extruder on it's own, so I assume it's the firmware then. Any messages in the log? Not sure what marlin can cause to disable extrusion. Newer versions allow dry run but that would require M111 being send with dryrun flag set and I do not assume it's in the gcode. No slicer does this.
