thermocouple setup
i use the dev branch and have not had any major issues with it
only the G33 which i will retest this week as soon new stepper drivers from watterott comes in. so far i'm on a 20/7-2017 relase
but i would also like to change out the bed thermistor for a thermocouple as i have to disassemble the who bed assembly to change out, and i have an idea that a thermocouple is a bit more though.
in the online config i can select MAX31855, but where do i select the CS pin ? is it the Temperature sensor pin

G33 has changed a bit with yesterdays release. Hope to have fixed some bugs with offsets.
right now i'm soldering up some tmc2100 drivers and once i have them in place i will do a G33

it seems like the old error is still there, if it helps config is attached
i still have the old dev version that works so i can switch back and forth
the same thing happens no matter where i start
what happens is that it homes and then it try to go past my X endstop
i could get a log if i knew where to get it
maybe a short video would be better if i can get my phone to do it in decent quality
i see that my config did not get attached 6 posts up
here it is: https://pastebin.com/9i2aAB5e
that should at least tell if my config is valid or not
#define Z_PROBE_X1 18
#define X_MIN_POS -3
Just for reference the important config options for the problem.
After homing you are at x = -3 and for the leftmost position it will be at -1 so 2 mm a part from x endstop. But at xhome positions it can not activate z-probe.
For initalization it calls void Printer::prepareForProbing() which is a new function to prepare to a valid state and I guess there the error starts.
At beginning it homes, which works.
Next is going to safe position, which is not needed on deltas, so I could not test that part (have only a delta with z probe).
Computation of target x position
that is -3 -19 = -22, so guess that is what you experience.
Correct would be
targetX = Printer::xMin + ZPOffsetX;
like I wrote in the remaining 3 cases.
Have updated the firmware and should now work better.
Thanks for the bug notice.
at home nozzle is at -3 on X
the probe is monted on the other side of the nozzle so it will be at X15
why i say this is that i have become unsure if my config is wrong
works fine now on my mendel90 :-D
