Like Rajaa I got a chinese knock off of a prusa with direct drive. It took a week and a few parts to get it working reasonably well. And Ya, everyone has tried various things for bed adhesion.
I’m using really cheap Max Hold hairspray in a pump bottle. It’s good for items with decent area in contact but I’ve been printing tall items too. For tall items you need a raft and the hairspray.
I’ve made a rule Height cannot exceed 150% of the base width in that axis.
Oh yeah, I Had a Solidoodle Press first. Took a month to get all the bugs out and it was printing really well, then the board smoked. Anyone got a suggestion for a replacement board? The Originals are not available.
