Major Ironing Issue - PERSISTENT - Ironing Experts Needed 🙂

Hi guys,

I am having consistent issues with ironing and need to figure out what is going on. I have to have the printer ironing parts as its essential.

What causes these clumps of filament? They only appear with ironing turned on.

Last time I did this exact same print profile, the prints did not have this issue (so it shouldn’t be the ironing settings). Filament is BL ASA and was in my AMS HT at about 11% RH. Before sending the print, I calibrated the flow dynamics and rate.

Thanks in advance, guys. This is a repeated issue that my printer keeps having. :slightly_smiling_face:

How long was it in the dryer at what temp? The calibration line is a bit out of focus but I see what looks like moisture pock marks before and after the smooth bit? Might just be the focus, but that’s the quickest way to see if there’s moisture, that line should be perfectly smooth (unless it’s got fibers in it)

What’s your ironing flow set to?

This is what that calibration line looks like.

Looks good to me. The filament was in the dryer for twenty-ish hours at 80 °C.

The flow is actually variable. I am using the MW file that has object based ironing flow and speed.

Also, here is what the top view looked like:

Maybe that’s why. Try changing the ironing so it’s not object dependent or variable. Then set it to 30% flow and 80mm/s.

Ok yeah, it was just the focus that was making it look dimply, thanks for confirming!

Well the variable part is quite important. This print profile is dialing in my ironing settings. Each of these are calibration blocks.

Do you have the file I’d like to get it a try

I like it a lot. I run it before every print I iron since ironing is such a variable process. The only part I changed was duplicating any one strip I want to target so that I have more than one strip to look at it. This way I can get a better baseline as, again, ironing is such a variable process.

Ahhhh, I missed that part. I should have looked closer.

Upon further use of my eye balls and based on the parts in the picture that haven’t been ironed yet, it seems as if your filament could use some tuning. The parts it’s trying to iron look very rough. Possibly over extruded.

The problem is that any defects caused from one copy of the model would be brought onto the other copy, even if the other copy has no issues at all. Basically snowballing all over the place.

You should try to start from something like 3x3 grid, just to set the settings closer first and to prevent a couple failures ruining the entire test.

Thanks looks like I had this one already saved in my tests collection. I’m printing it now overnight because its almost 4h for the first plate.
