	*Known bugs: machine has currently been tested in multiple day production runs and is stable at 6 bricks per minute.
	:*When solenoid valve runs with 2 Power Cubes at 28 gpm fluid flow, different control code needs to be used. The updated control code is designed for parallel operation, which does not work well with a series valve.
	~~:*Issue can be resolved also by using the same code, and a parallel solenoid valve instead of the series solenoid valve that is currently being used~~
	:*This bug was not seen when a larger diesel engine was used to power the brick press in 2010 at 30 gpm fluid flow, because the simpler control code at that time was written for series operation. A brick pressing rate of 10 full size block per minute was achieved in 2010.
	~~:*Control code optimization needs to happen to optimize power usage~~
	~~:*Log splitter hydraulic pumps can be used to allow for the use of a smaller engine. This has not been done yet.~~

=Specifications of High Performance Model=
*Block is plain block, not interlocking. Please see discussion on [[Interlocking_bricks]]
*See [[CEB Press Genealogy]] for past versions.
*Open source hardware, controller, and software (CC-BY-SA, GPL)
*Controller includes automatic pressing and manual mode. Manual mode does not use microcontroller - but only physical connections.
*Powered by a hydraulic power source, such as [[Power Cube]] or a tractor hydraulic take-off.
*Full size bricks are 4"x6"x12", plain flat-faced bricks
*Brick height is adjustable from 1"-4"
*Brick dimensional variations: +/- 1/16". This assumes uniform soil. Soil uniformity will determine height uniformity of brick.
*6 full-sized bricks per minute at a 10.6 gallon per minute hydraulic flow. Brick pressing rate will increase with a higher hydraulic flow, up to the maximum rated flow of the hydraulic solenoid. See [[CEB Press v17.08 Calculations]]
*Hydraulic solenoid valve is rated for a maximum of 28 gpm fluid flow at 3000PSI
*Fuel consumption with [[Power Cube v17.08]] running at 10.6 gpm fluid flow - under 1 gallon per hour
*System hydraulic pressure - 2300 psi. Adjustable up to 3000 PSI.
*Pressure bypass preset - 2500. Adjustable up to 3000 PSI
*Comes with hydraulic quick couplers ready to be connected to a power source
*Weight - 1700 lb
*Moving: brick press is moved with forks. Footprint (with legs in the inner position) allows machine to be placed in the bed of a 3/4 ton pickup. It has adjustable legs for uneven terrain. Machine can be moved around on a trailer (not included)
*Material cost: see [[CEB v17.08 BOM]]
*3'x6' grate for tractor loading. Includes soil deflectors
*Includes hopper shaker to help soil move down the hopper. However, the shaker is not needed if soil quality is good.
*Known bugs: machine has currently been tested in multiple day production runs and is stable at 6 bricks per minute.
:*When solenoid valve runs with 2 Power Cubes at 28 gpm fluid flow, different control code needs to be used. The updated control code is designed for parallel operation, which does not work well with a series valve.
