Theres also the possibility of a damaged output gate in the fpga. they are only 3.3 volt fpga's, and 5 volts is enough to write their obits. I damaged a couple 7i90HD's until I put 7i42TA's into the setup for overvoltage buffers, no problems since and they do give you nice screw terminals for hookups. My current setup has 2 blown stepgens so I have 4 enabled, useing 2 and 3 in place of 0 and 1. Thats a custom hal file but no problem for me, and LCNC doesn't care if you diddle the hal file to fix our stupids. :) So if there are spares, use them. > El jue., 12 mar. 2020 a las 11:03, Gene Heskett > (<ghesk...@shentel.net>) > > escribió: > > On Thursday 12 March 2020 08:53:39 Leonardo Marsaglia wrote: > > > I'm going to check the flat cable, that I'm missing. > > > > > > El jue., 12 mar. 2020 a las 9:48, Leonardo Marsaglia > > > (<ldmarsag...@gmail.com>) > > > > > > escribió > > > > I was gonna suggest that, Leonardo, I've had flat cables that had > > gone funkity in just a year because they needed another trip thru > > the vice to bring the crimps and the idc connectors fully together > > because they never fully latched the first time.
