      @jacotheron said in gcode everywhere... a user friendly approach to config?:

      Endstops: X and Y is at MAX, and Z is at MIN (unless you changed its locations). I could not find if endstops are Normally Open or Normally Closed.

      According to the config you linked they are Normally Open:

      // The pullups are needed if you directly connect a mechanical endswitch between the signal and ground pins. const bool X_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop. const bool Y_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop. const bool Z_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop. const bool X_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop. const bool Y_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop. const bool Z_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.

      Having these set to false means Normally Closed and true stands for Normally Open. This get's a bit clearer in the original Marlin comment of this part

      // Mechanical endstop with COM to ground and NC to Signal uses "false" here (most common setup). How to proceed from here

      My personal recommendation on this topic would be to start from scratch regarding your config.g and other files. Create a fresh set using the Configuration Tool using the values you can find in the Marlin config as already posted by @Jacotheron above. If anything is missing or you cannot find a value yourself, just ask here we have kind of 24/7 support here. šŸ˜‰

      It seems to me that somewhere on your - sadly - bumpy way you took a wrong turn and never found back but just found more places to do wrong turns. When something is as wrong as you described your setup it is time to start fresh IMHO.

      But as others already stated, we are happy to help here. šŸ™‚

      I'm sorry to hear that you are still having problems. What's wrong with the first layer?

      There is an issue with some older firmware versions if you re-home Z with mesh bed compensation applied. I recommend you upgrade to firmware 2.01 and then run G29 to generate the height map again.

      Ah, that could be where the error lies...

      In config.g I have

      ; Tools
      M563 P0 D0 H1 ; Define tool 0
      G10 P0 X0 Y-9 Z0 ; Set tool 0 axis offsets
      G10 P0 R0 S0 ; Set initial tool 0 active and standby temperatures to 0C
      M563 P1 D1 H2 ; Define tool 1
      G10 P1 X0 Y9 Z0 ; Set tool 1 axis offsets
      G10 P1 R0 S0 ; Set initial tool 1 active and standby temperatures to 0C

      In Cura I've reset both to zero. I'll try again tomorrow!

      Thank you very much for that explanation of relative and absolute extrusion. I thought it was something like that but it wasn't very clear in my head! That's a big help in understanding it.

      I'll give it a try later this afternoon hopefully!

      @dc42:

      Some fans can be made to work with PWM if you set the frequency (F parameter in M106) very low, e.g. 100 or even lower. But the 30mm ones that E3D supplies didn't work with PWM at all when I tried them.

      Ah, that doesn't sound good! I'll try swapping them as suggested above just to check. The fan that throttles down is a 40mm Noctua that I bought.

      Shame that E3D fans have to be on full speed, suggests the cooling fins on the chimera aren't very effective. I had heard rumours to that effect prior to their new design coming out.

      Yes, right resistor (R37). You see the 330 ohm value in the photo. Not sure about the solder bridge.

      But one other thing, if I boot from just a 5V input (usb), it boots up fine. All the endstops trigger and show hit in the machine properties.
      –---
      10 mins later...

      Mmm, after more testing I'm not quite sure what to think. Could be a weak wifi possibly. I just rebooted with the usb and 15v connected and it's fine and dandy. Repeated it with the usb disconnected and again fails to boot. Plugged it in again and bingo!

      TBH, if that's all it takes I'll live with that. It's just an OctoPi I use for the camera, so it'll stay on the printer anyway. Be nice to have an explanation though...! šŸ˜‰

      That seems right, I did a restart and it showed up at the same IP address. Very pleased so far. Much easier than I thought it was going to be.

      Excited for tomorrow to try it out and configure the firmware.
