Parse Error - Fixed (sort of). Now nozzle bed heating issue.

[7milesup]

Well, here I go again.

Thanks to @mvdveer and @smirk help, I was able to get my printer to print, however, there was a big issue with how it went about heating the bed and nozzle, with the nozzle heating up to print temp, then cooling off to probe temp (150C) and then back up to print temp.  After searching a bit, I found that some G-code in my slicer (Superslicer) needed to be added. 

I added the following to my Slicer start G-code (in red).

; M190 S0
; M109 S0 ; uncomment to remove set&wait temp gcode added automatically after this start gcode
print_start EXTRUDER={first_layer_temperature[initial_extruder] + extruder_temperature_offset[initial_extruder]} BED=[first_layer_bed_temperature] CHAMBER=[chamber_temperature]

Then I had parsing issues related to the bed (M104 S and M109 S) that would halt the printer.  After researching some more, I added in the code you see for the M140 and M190 and commented out the existing code..  Now the bed heater does not start until after all of the routines are done, which is a while and the extruder is sitting there cooking at print temp. 

Obviously I have this messed up, but not sure how to correct it.  If I delete the g-code out of the slicer the sequence is correct but then I have that funky hotend heating up, cooling down to 150 then back up to print temp. 

I also have another question(s) about QGL and mesh bed leveling.  Do you have your printer do a QGL for every print?  What about mesh bed leveling.  I am assuming that the mesh bed is done once and saved, then recalled by the g-code.  I can start a different thread for those two questions instead of muddying this thread up.

@claudermilk What do you use for a slicer?

 

[claudermilk]

I use Super Slicer. I'm starting to play with Prusa Slicer 2.6.0a5 to see how the organic supports work.

I need to try out Cura again. I tried it back in the day but paid for and used Simplify 3D for years. Once I built a Voron, I started using SuperSlicer. It's been working well for me but... A man's gotta F up a good thing and try something different.

Same here - just did the upgrade to V5. (Was cheap/discounted) Have not tried it as yet. After reading this thread, have downloaded Cura, but not installed yet. Took me a while to learn superslicer and I still don't fully utilise all of its potential. On the Creality printers used Simplify3D and it just worked -Marlin based back then. Simplify3d did not play well with Klipper, therefor the switch to Superslicer.

I have Cura installed, but haven't messed with it. My printer ing the bed on it's calibrations put that idea aside until I can get it back to printing decently again. Almost there--just want to get that TPU figured out and a Z wobble resolved if I can.
