CEB Press 6 - Overall Machine - Firmware
Aidan and Gabe,
I have written down the CEB Code requirements:
Please look that over and let me know if you have any issues with those requirements. We need to make minor code adjustments to implement these.
One known issue:
Aiden and I observed that the main cylinder is not going down all the way in timed mode - it stops 1/4" short. This needs to be addressed. It appears that the most efficient way to achieve this is by using pressure sensing, not timing, for the thickest brick setting (ie, maximum pot value) - as timing is apparently a little inaccurate because of code run time effects.
Also, I highlighted shaker turn-on strategy in red. From my experience 3 years ago, that strategy allows the machine to press more bricks, because excess fluid is diverted from drawer motion, which is overpowered. Now one may argue that we should turn on the shaker during ANY motion of the secondary cylinder, but this should not be the case. Currently, I believe the code has the shaker motion on by itself. That is too much power to the shaker if we use 54 hp, so it's better to divide power between the shaker and drawer. We can, on the other hand, feed all the power to the main cylinder without problems.
Finally, we should begin the drawer
Does this make sense?
