I’m having problems with ironing, this one was with 150 mm/s speed, %38 flow, 0.2mm spacing and inset with 90 degree angle…
What is this problem I’m having and how can I fix it, can anybody help??
The most important points are: Don’t try to fix a poorly calibrated filament profile. If your filament calibration is wrong, the top layer of your ironing calibration prints will not be smooth before ironing, so your ironing calibration results will be wrong and will need to be printed again. Use a combination of [infill density and number of top layers] that gives a top layer smooth enough to be ironed. >5 layers on 15% gyroid infill worked well, but I usually choose 7 to be safe. ironing angle (depends mostly on model geometry, but usually 45 degrees from the layer that should be ironed works best, which is also the default), ironing speed (depends mainly on the filament, the nozzle temperature (and probably on the temperature, environment/fans/air currents)). There is probably more than one speed that works. Choose the slowest if you are not exclusively ironing large surfaces, for greater safety and to obtain generally more homogeneous results for irregular geometries/smaller pieces. Ironing flow % (depends mainly on the ironing speed and a slight over-/under-extrusion of the filament profile). ironing line spacing (default works well with 0.4 nozzle, I haven’t tried much with other nozzle sizes, maybe there is room for optimization, but 0.075 for 0.2 nozzle and 0.225 for 0.6 nozzle gave me acceptable results). These are some things I look at…
