My LDO Voron 2.4 350 Rev D started smelling very bad after approx 200h of printing over the last year. Please don't come with comments like "usual ABS SMELL". It is definitely not the ABS! This smell is really horrible and spreads arround in the complete house.
The reason seems to be using the heatbed at 120deg for drying silika for a long time-period (> 8h).
Now I want to replace the heatplate of the bed, which smells like that bad taste.
Fabreeko offers heatbeds with suitable adhesive, or probably even without. But they are currently out of stock and I dont know how to order from Germany (probably quite expensive, when including shipping and taxes)
