Reading the peachy beta kit instructions, it looks like the calibration step is smart enough to scale the Z per "drip" based on the height provided. Is that correct?

If so, and we replace the basic dripper with a peristaltic pump, it seems like the drip contact detection mechanism should still work about the same. If the volume of the pulses from the peristaltic pump is small enough that the z-level rise in the container per pulse is appropriate for the target layer height (i.e. operates at a similar scale to dripping in a small container does), I would think it would be OK. Looks like I can get an appropriate 12V pump (one which pushes 20-100ml per minute) for about $10 plus power supply (I have a 12v dc controller for a train that should work for testing). May be a very easy mod?

So....that still leaves the question of what the maximum deflection angles the printer can support are, so it doesn't have to be mounted 30' in the air to get larger build volumes.
