Modify gcode without stl

I have only gcode, NO stl file. How do I modify gcode to specify 3 things.

  1. Temperature at least 230
  2. Layer height .3mm
  3. NO retraction.
    I want to print 3DLabPrint planes and am told these changes are needed.

sonofcy,

I would google “gcode editor”. There are a few to choose from, but I am guessing that there will be a bit of a learning curve. I don’t think it would be very easy to edit the gcode as text. Layer height translates into z motion. You would have to modify every z command at each layer change. Eeeek!

Since the person telling me this has printed dozens of models, I doubt he is doing the layer height that way, at least I hope not.
