Re: Multi-resin printing with the Peachy Printer - 10 years ago
Quotehygy Maybe U can lift the resin easily with two balloons connected. One ballon is inside the salt water, the other ballon is outside the tank. When U compress the outside ballon then the inside ballon increase, so the water level incresase. If U stop compressing the outside ballon then the original level will be restored. the balloon on the outside (that you sqeeze) would steal water from thby ert485 - Polar Machines, SCARA, Robot Arms

re-thought the water level - pressure problem actually the effective depth is the top of the water in the reservoir to the lowest point in the tube when the tube is full of water (ie. it siphons down the tube as well) so that means if the drip point is much lower that the reservoir it will have more consistent flow from full to empty.by ert485 - General

Peachy Printer drip system alternatives/fixes - 10 years ago
I'm putting this in the general section because there isn't a peachy section yet, the rest of the related threads are in polar bot & robot arm section http://forums.reprap.org/list.php?185 Some of the concerns for the drip system / water metering: (maybe some are irrelevant, maybe there's more) -water resevior level decreasing slows the drip -are drips consistent enough? -want faster / contby ert485 - General
