For those working with the 1000 - 1500mm machine and have 3 - 2080 - 1460mm supports - and only 2 - of the 2040 - 915mm support but want the full support of method 1 - take your 915mm and space evenly under the Y axis front and rear supports and attach and space the 3 2080 x 1460mm as you would in method 1 - this does make the frame higher from the table but solid support on ends for spoiler board is achieved.
