ZERO KELVIN HOTEND TEMP
-
@dc42 I ran both S0 and S1
also my replacement thermistor arrived so I installed it, just the clipped end.
-
Can you switch from temp1 to temp2 connection on the board and update the M308 to reflect?
M308 S1 P"temp2" Y"thermistor" T100000 B4725 C7.06e-8
Does it still show -273?
Can you make up a much shorter lead for the thermistor to see if it's a break in the wiring?

1000 Thanks to you my friend! Your fix did not work bc i didnt try it but it did lend itsself to me finding my hot end thermistor plugged into out6 like a fan when I went to try it. I have no clue how it got there.
looks like its always anoob mistake .

So to to the devs, how well does this board handel CNC? ive got a couple CNC builds going rightnow and I ended up buying another one of these boards since I thought I toasted the heater/driver. So I will probably use this second board for a smaller 3 axis NEMA 17 cnc machine. hoping to power mostly everything but the spindle from it if possible.
I heard there is a CNC firmware. whos the main guy on that project?
My other build is a 12Nm NERMA34 4 axis, w/5hp spindle running with 110V in planning on using a rotary phase converter to hopefully get all 3hp out of that spindle. Im assuming this board cannot supply 6A ish per stepper right?

@adalton5683 Probably best to ask your CNC question in a new thread in the CNC forum for some more visibility.
