I did some work with 400E's and have can give you a couple things to try with your Y axis problem. 1. There is a file called stepperparms.exe that will load all the stepper parameters on the PCL IC's. Your y axix chip may have corrupt data on it.

I've gone round and round on this very subject with our manufacturing engineer. He prefers to use panel fiducials and I prefer board fids. I've seen the result in placement from bowed PCB's in the machine. Skewing the board a fraction will throw off

If you get the price for the tray and holder from Siemens you will follow Dave's recommendation. To get the 0 point for the tray ( from where you measure the first pick position )you set up the tray on the 7th track ( type 51 ). After you sent the da

Have you tried using offsets to begin to move the head away in the Z axis while it is moving in a lateral ( X Y ) direction. The spikes are difficult on the Ersa, but experiment with hitting the location from different directions may help also.

I need to calibrate vision offset of MPM Accuflex printer. According to manual I need the calibration stencil with 49x49 holes. Does anybody know what is the approximately diameter of those holes and what is the distance between rows and columns?

I mean if you are using the same stencil for the top and bottom of a board. Thanks to everyone for the help. From what I gather, it will work when the stencil cut-outs are offset from center in the Y-axis. Doesn't work too good in the x-axis, beca

I believe Mitutoyo makes a CMM for that application. They were soliciting the idea at APEX show a couple of years ago. I believe they were going to develop some software to do just what you are asking for (following the IPC-9850 format). A CMM, ho

Wierd thing happened today with the HSP4791. All the programs and component definitions were wiped out (luckily they are all backed up on the terminal). And since the air compressor was shut down today to change the oil in the compressor, the 4791

"When the head rotates, it rotates about the center (long) lead of the bug. Therefore, the x/y position of that lead does not change as the head rotates." Heh-heh. You'd think so, wouldn't you? Have you observed this with a magnifying glass? What

We always do block conversion and have never had a problem. Is there a problem with the accuracy of your PCBs from the vendor? If you can get a panel placed correctly the next panels should also place correctly. I just created a 2x8 panel with hal
