"Left line" is printed with 120° after homing - cold extrusion #134

Closed krammerj2486 closed 3 years ago

krammerj2486 commented 3 years ago

Description

Homing is done with a nozzle temp of 120° and the bed temp from the G-Code (in my Case 80°). After Homing the line on the left side is "printed" with 120° nozzle temp. Then it heats up to the target nozzle temp (in my case 240°) and starts printing the skirt. Then it worked fine, but the line on the left side is missing.

Steps to Reproduce

  1. Starting a PETG print job from OctoPrint, with 240/80 as a target temp. No preheating on the printer or OctoPrint is used!
  2. Printer starts to preheat the Bed to 80°
  3. Then the "Heating up and homing in progress" message ist shown on display
  4. Nozzle is heated to 120°
  5. Homing takes action, Nozzle heating is switched off while probing
  6. After probing the nozzle is heated to 120°
  7. and started to print the left line with 120° nozzle temp and 80° bed temp
  8. Then stopped at the left front corner and heated to the G-Code target Temp 240°
  9. printing the Skirt with correct temp setting

Actual behavior:

Line is "printed" with 120° s for probing.

It heats up to the previously set temperature. This suggests T=120C was previously set. Can I have a part of your gcode? (The first layer)

Two things you can try:

krammerj2486 commented 3 years ago

I'll try the new build after my print is finished. Find the GCode snipped attached to this message...

Testfile_firstLayer_0.2mm_PETG_CR6SE.txt

krammerj2486 commented 3 years ago

I don't think that it is heating to the previously set temp, because the 120° came from the homing process.

In the first lines of the GCode 240/80 is set. .. M190 S80 ; set bed temperature and wait for it to be reached M104 S240 ; set temperature

Is that with the prerelease firmware @krammerj2486 - you should see "CR6-Release6-Pre1" in the about menu.

krammerj2486 commented 3 years ago

Now I tried it with the prerelease 6.0. The problem is still there, but now the printer tries to print the purge line with 145°. In the middle of the second purge line it switches to 240°.

Sebazzz commented 3 years ago

Do you have a minimally reproducible gcode file and exact reproduction steps? (I can’t check from my cellphone if you did already put it in the issue)

You have M109 after drawing the purge line. You have M104 earlier but that sets the temperature but it does not wait for it. After homing it of course immediately proceeds drawing the purge line, but at the temperature set because. But it homes immediately, turning off the heater.

Am I wrong in stating this isn't necessarily a bug? You instructed the printer to only wait for the temperature after drawing the purge line.

krammerj2486 commented 3 years ago

You are right, that comes somehow from PrusaSlicer, in Cura generate always M140 immediately followed by M190 and 104 followed by 109. Strange I have to take a look what is wrong in PS setting.

M140 S65 M105 M190 S65 M104 S210 M105 M109 S210

krammerj2486 commented 3 years ago

I took a look at prusaSlicer but I found no setting that could influence the "wait for nozzle temp". The start code seems ok there are no temp settings in it, but the slicer inserts the wrong temp gcode (or the code to wait for the nozzle temp is missing)

Sebazzz commented 3 years ago

Can you show what start gcode you are using in PrusaSlicer?

Sebazzz commented 3 years ago

Unless I'm missing something, you should add a M109 S[first_layer_temperature] in your start gcode. Please also see the comment from the PrusaSlicer devs here: https://github.com/prusa3d/PrusaSlicer/issues/2961

Sebazzz commented 3 years ago

May I assume this is purely a start gcode thing? That you didn't run into it in the previous firmware is because the heater wasn't paused while probing. The gcode was always incorrect, but now it actually shows 😉

Feel free to reopen if I'm incorrect.

krammerj2486 commented 3 years ago

where would you place the "M109 S[first_layer_temperature]"? I suggest after the G92 E0, is this OK? You wrote "unless I#m missing something" - what are you missing?

Sebazzz commented 3 years ago

After the G28 it should be added.

krammerj2486 commented 3 years ago

OK thanks!
