alexsomesan said:I DO NOT RECOMMEND THIS SETUP ANYMORE! I have had countless random errors communicating with the drivers. Sometimes they'd all work fine, other times some drivers would return bogus values. There seemed to be no pattern to the errors, but eventually I was able to determin that the presence of the stepper wires in the vicinity is the main cause of issues. Because the stepper headers are right next to the drivers, the high current wires for the motors run exactly along the SPI jumer cables. This causes inteference and improvments in SPI communication are immediately visible when unplugging the motors or tucking their cables below the line of the StepSticks.It's taken me a while to figure it out and we've also had reports on this thread about mosfet activity interfering with the SPI communication.By comparison, the RADDS on my printer uses the soldering approach I originally posted here. Soldered SPI wires run on the back side of the board. This has worked consistently as expected without any issues for a couple of months.I advise everyone to do the extra work of soldering on the back unless you enjoy debugging your printer more than actually using it.
very sorry for
the late answer…. But I bought an old house and now I’m refurbishing nearly
everything and I’m very busy for this. The WAF for 3D printing is also very low
at the moment, so candle light holder or vases doesn’t really matter at the moment ^^ Bathroom, colors and
so on are more important ;-)
doesn’t matter for my problem. After
some try’s maybe I have a completely misunderstanding and the CS is maybe not
the problem. I have inserted the SD Card directly in the SD slot from the RADDS
display and also directly in the RADDS board (MicroSD). The card is formatted
with FAT32. In the display I can see, that Repetier discovers the card (per
display and also directly in the RADDS) and also see if the card is removed. So
maybe I have just a stupid error in my config files?
I'm new to Repetier, so maybe I forget some basics......
