Well, here is the short, bought one a year and a half ago, from ebay…Yep big mistake, ebay would not enforce the one year warranty, nor could I get any replacement parts for the printer. So, I purchased a MKS Gen V1.4 Board to do a replacement. I have identified most of the needed connections, will have to sort out the end-stop leads, no problems there. However, the big hold up is identifying the connections used for the HBP-Therm inputs and the two extruder Fans and the display ribbon cable connections, not sure how those are identified on this particular board except for the display…I think I just need two headers and split the ribbon cable. ANY help making the switch will be GREATLY appreciated. any help out there?
Interesting since they use “Like” controllers. I will definitely have to check out the schematics. I wish there was more information on the MKS Gen V1.4, its supposed to be open source but, not a whole lot on the net about it that i have found (no schematic, just connection labels). I have figured out that the control lines for the two extruder cooling fans are not set up the same, as the extruder 2 is D11 I think, has the driver/buffer onboard to handle it, while the pin for the Extruder 1 fan, is D6, one of the servo lines. I may find a logic relay to handle that fan, just keep it simple. I will pull together all the documentation and post it once i have it all set up. Thanks for the heads up about the thermocouple vs Thermistors. Any other ideas?
