			All the exterior module [[seh4cad\|Cheatsheets]] I've been uploading are looking at the module from the exterior of the building which may be confusing when it's time to install electrical boxes. Probably will just stick with the scheme for the first floor and start drawing the cheatsheets from the interior for the 2nd floor.

			Scalable CEB Circuit. Up to 3 PowerCubes with hydraforce part. GPM numbers assume 30gpm pump. Pump can be replaced with intake manifold. Scale to 3 powercubes input. Quick disconnect one and put it on tractor. Put it back. etc.

			Showed some of the workshop participants how to install drawer onto CEB press. Replaxed powercube coupler. Forklift did not show up to move press. Will try to demo press tomorrow.

			Updateed BOM. Incomplete

			Took apart controller and discovered possible grounding issue in usual usb port case location. Reassembled and issue has yet to strike again.

			Reassembled Ceb press with primary arms parallel to press chamber. Press chamber side plates being awfully out of square (due to chamber sides bring totally out of square) causes this to be a slow process. I believe an issue with the way the chanmber was welded causes the blocks to delaminate during ejection because the chamber cross section shrinks as the blocks go up. I tried correcting this issue with shims. The outcome of this shim modification is unknown due to the powercube coupler failure. Loose motor mount bolts caused the hard pump shaft to grind away the softer coupler's splines. Machine has been down since February 3.

			I had gotten the nylon blocks bored out to press fit bushings in since the bore was fully worn out on all 4 bushings. Grinded off old bushing alignment angle corner pieces and welded new ones on. Also dropped the drawer lift stop plates to 1/32" clearance. This was done before coupler failure.

			Delivered blocks to copper bank.

			Automode issue persists. I now suspect hardware. Will try some more debugging later.

			Random CEB thoughts:
			#728psi - maximum pressure we are pressing our blocks with. I think it's too low for the high clay soil we are using here. 2700psi fluid pressure, 5" cylinder, 6x12.125in press plate. I'd love to try a larger cylinder.
			#High clay soils are very moisture sensitive. If we vary by ~3% then we make bad blocks
			#Im going to cut open the drawer and work on the guide rail system soon. It needs an overhaul for this machine to stand a chance as a production unit.
			#After pressing 3k blocks the main chamber spread itself on its oversized bolt holes and i need to re shim the press foot. Recommend making the bolt holes with less tolerance.

			Changed out the pressure gauge on the valve manifold. Old one somehow bent its needle, wasn't reading right, and was leaking. New one seems to be of superior quality.

	Debugged automode in code on block press. Fixed the issue. Working code: [[File:BelizeCEBFirmware19.11.zip]]		Debugged automode in code on block press. Fixed the issue. Working code: [[File:BelizeCEBFirmware19.11.zip]]
