Replacement CR-10 CR-10-S4 Control Board Mainboard

This is a replacement control board for CR-10, CR-10-S4, and CR-10-S5 3d Printer. Troubleshooting a bad board:  (before you deem your board bad)  If you have one motor that is failing to move.  Try swapping motor channels with an axis which is working.  This can tell you if you have a broken connection, and test the channel of the board which is suspect. Some CR-10s out there have been shipped, by other vendors, with bad control boards.  The most common defect reported in the community was a board with a bad Micro SD slot. If you have a printer which works with every feature, but simply will not consistantly recognize your Mirco SD card, you may have a port with broken or bent pins inside.  This is a quick fix for this issue.  However, if you'd like the SD port repaired, by us, we can do that for you.  Typical turn around is 4-6 days.  Please let us know if you'd like the port repaired. If you'd like to swap you board for a new one, order this.  Installation is as easy as plug and play
