And Back to getting my Two Trees Sapphire Plus working
In other threads, I've described my adventures getting this printer working. As of February, Two Trees had shipped me a new thermistor to replace the one in the unit that they determined was defective. And so, we continue.I've managed to take apart most of the extruder in order to get at the thermistor. I'm including some pictures. I've removed a larger cylinder that, due to the heavy wires, I'm assuming is some sort of heating element, that was locked in with a set screw. The thermistor is a much thinner cylinder next to it. I can't figure out how to remove it as it is jammed into its hole pretty tight. No set screw. I've tried pushing it through from the opposite end, but it won't move, and before I stick the thing in a vice and start putting some heavy duty pressure on it, I thought I'd check here first. Should this thing be the hard to get out? As always, thanks for any guidance. Ron

Two Trees Sapphire Plus - displaying or printing firmware settings?
Okay, I'm getting ready to run some initial tests on the replaced thermistor. I'm wondering if there is a way to display or otherwise print out the firmware settings? Also, there are 2 sockets on the motherboard (An MKS Robin Nano v1.2) labeled "12V/24V Constant Output". Wondering if it's 12V or 24v. I'm not at the printer right now, but off the top of my head, the only way I can think of to determine what voltage the printer is using is to stick a voltmeter on the leads coming from the power supply to the mboard at the contacts labeled "Power Interface". Or is the power actually determined somewhere else on the board? The original Robin Nano manual mentions something about a "dedicated power chip" (I found a v1 manual on Github, but still looking around for a v1.2; probably someplace obvious that I missed). I'm attaching a picture of the v1.2 mboard from the instructions that I received, just for reference. Thanks again.Ron
