exxos blog - random goings on

@exxos I remember downloading the latest marlin build and then applying all the options to it myself manually, then it worked fine but it is most definitely a pain in the arse and not something I'm going to do with my printer again as its now working as I want it to.

That's the thing though isn't it, if you download the Marlin firmware, as you can configure it for just about anything, then you would expect to need to configure it. But when BTT release fires you would at least think they would be set up for the board supposed to be for. I mean the firmware.bin (480K one) works fine so assume that is the default one sent with the board. But when I compile those files, it comes out at 159K.

@exxos That is bizarre and must mean something big is missing, probably lots of code commented out still that needs enabling? I know that I had to select the correct steppers, bed size, bltouch, touch screen and a few other things like distances from head to BLtouch etc.

[exxos]

I have figured it out. The problem was not sleeping for three days :cry:

I had unplugged the X-stepper while troubleshooting the odd driver issues and forgotten to plug it back in again. Annoyingly it was the X-motor I was clicking in Pronterface after compiling and uploading the firmware :headbang: :headbang: :headbang: :headbang:

Commence chair smacking then I guess...

Endstops now working. BUT WTF minimum temps for the heater bed after I turn it on ?!

Code: Select all

Reporting endstop status
x_max: TRIGGERED
y_max: TRIGGERED
z_min: TRIGGERED
Setting bed temperature to 80.000000 degrees Celsius.
Error:MINTEMP triggered, system stopped! Heater_ID: bed
[ERROR] Error:MINTEMP triggered, system stopped! Heater_ID: bed

echo:Err: MINTEMP
Error:Printer halted. kill() called!
[ERROR] Error:Printer halted. kill() called!

EDIT:

Oh guess I should connect the sensor :lol: :roll: Question is where does it actually go ??


EDIT2:

Bow down to my red LED on greatness !

So something is a bit out as the 80c temp set comes out at 96c on the thermal probe :roll:

Started doing my own thermocouple table which is taking ages. But how accurate do they need to be ? Most just seem to go up in 5c increments . One guy mentioned marlin would "fill in the gaps" but I cannot find if that is even true or not ?

Round to the nearest integer?

Round to the nearest integer?

I did wonder that :roll:
