I recently received my mainboard with drivers, heat bed and control panel from tinyfab. While setting everything up, I came across two issues: First of all, the case of my Cetus Mk3 appears not to be a perfect fit for the Tinyfab mainboard. It seems the 3D printed part that holds one of the switches gets in the way. That is only a matter of a few millimeters though, so i might be able to modify the plastic part to accommodate the mainboard.
The much larger concern to me is that the control panel shows the bed sensor readout as 999, regardless of whether I use the FPC or external sensor connection. From what I can tell, a readout of 999 is the smoothieboard's way to indicate that the thermistor is not connected at all. I have probed the wiring, that does not appear to be the issue. Any ideas? Is there a setting I might have missed, in hardware or software?
Sorry for the delay. you will need to change the bed config to PT100 and change the slope to 0.01 and intercept to 0. This is due to maintaining hardware compatibility to the stock mainboard. Please check the reading, you can tune the slope and intercept if you find it vary from real temperature.
