This particular Yamaha Head I/O Board is a common failure. Yamaha supply an updated version which is less likely to fail. The cause of the problem that you see is due to the connectors on the flexing and damaging the inner layers of the board. The on

Does anyone know what an "Axis Head 1 Theta DAC limit error during Move Absolute Command" may mean? It occurred during production. I have checked through the board's program for errors but cannot see any.

Are you sure the anvil is coming up? You might try running a program w/o parts or boards (no continuity check) and watching to see if everything is moving when it should be. Do you use continuity checking? If so, what are the results?

I remember this problem but can't remember exactly what the reason was. It might have been the wrong pullup resistor on the MEI interface board used for the home photo on the y axis. You are right, after a couple hours the machine would work fine.

Dave is right. There is no machine on the market which can handle a 1.5 m long "board". If you or someone else will have to tinker with a custom made machine, it will be less expensive to use a used machine ( I could be offering some used Siemens mac

Hello Rob, I was able to get the machine to zero, apparently replacing the circuit board on head 2 conflicted with head one even matching the jumper settings to the old board. Once I marked the head as not mounted, head 1 zeroed. I re-checked the ju

One thing that has to be considered when using rheometric pumps is that the board support should match as that of the pump head being used. You can print 6" boards, but you should really still use board supports upto 16". As mentioned previously if t

Hello, just a quick update on this issue. I disabled head 2 on beam 2 which was the second head I worked on, and left only active the head that I had work with first and ran dry cycle with. after disabling the head 2, the machine zeroed with no pr

Solderpaste types have a big effect on print performance. Go to this link to see if the solderpaste you are using has been tested, see "Rheometric Pump Paste Tests" under MPM: http://www.speedlinetech.com/news_publications/application-notes.aspx?OnI

Thanx for all your recomendations, we already ask for a 3D SPI and help us well, we are asking for a ultrasonic stencil cleaner. By the way how do you deal with the 'head in pillow' defects? is there a solder paste alloy / profile issue?
