Hi, I'm not familiar with your multimeter, but you want to make sure it is set for DC (just in case it wasn't). Then: X Step P8-12 X Dir P8-11 Y Step P8-16 Y Dir P8-15 Z Step P9-15 Z Dir P9-23 A Step P9-11 A Dir P9-13 Then: IOPWR# P8-7
P8-7 must be low to enable the HCT541 buffers. If you've modified the HAL code and removed that output and the signal it is connected to, the board will not work, even if you've tied pin 1 to pin 10 on the DB25 connector. Jeff .
