Arms crack? On the print? No.
On the printer? No.
I was having a heat-dissipation issue because I messed around with the hotend assembly. Heat was working backwards and softening the filament. I've got a delta printer that uses boudin tubes and the driver is mounted off the hotend. So, it is sensitive to expanding filament.
And, yes, it does support ironing. But, I leveraged the shiny effects of the glass print surface to get that effect.
