Thank you for the quick response. Yes, it does
Ok, so what do I need to do next?
After realizing my mistake, here’s what you’ll want to check. First test between the Zmin wire and the washers. If that’s not working, your break in the circuit is on that path - but that rarely fails, so you will likely need to grab a spare piece of wire, about a meter long, and connect one end to one of the bed leveling washers. With the machine on, you can go to the ENDSTOPS monitoring screen.
You can verify your wire and the connection to the washer is good by touching it to the grounding screw in the case with all the black wires. The indicator for Zmin should indicate that it’s triggered.
If you touch the other end of the wire to the nozzle of the M175v2, it should indicate on the screen that the Zmin is triggered as well. If not, work your way back to identify where the connection is missing. Order would be nozzle, screw on the hotend for the Zmin wire, pin #3 on the toolhead side, pin #3 on the carriage board side, machine side of the harness in the junction box, and board side of the harnesses in the junction box on the back of the printer, and then you’re basically back at the grounding screw.
I have an E1 error on startup, I suspect my shop temp may be below a programmed min temp. Is that possible? My shop is about 40 right now, if so can I lower that min temp?
40F degree shop wouldn’t cause any mintemp error. Below 32F? I’m not sure.
Is it only when you run GCODE, or can you manually raise the nozzle temperature through the printer’s menu?
What does the reported temperature look like before and during the temperature change attempt? Does it have 0/0 C, then 0/180 C? That’d be a temp sensor failure. Does it have something like 10/0 C, change to 10/180 C and never change before the failure, or does the first number (temp sensor reading) raise past 180 C and keep going prior to the failure? Does it bounce over and under 180 C for a while before giving the error?
