New experimental firmware 0.65f-dc42

I've just released firmware 0.65f-dc42 at [github.com]. The changes since 0.65e-dc42 are just a couple of bug fixes:

* M221 command (set extrude factor override percentage) works again

* If a print from SD card was paused and reset, and then a new SD card file (or the same one) was printed, then depending on the file contents the printer would sometimes reset itself.

For differences from RRP's 0.65e and where to get the 0.90 web interface that is compatible, see [forums.reprap.org].

Great article!
Thanks /Joar

Hi,


since the Firmware 065e-dc42 it seems that something is buggy with stopping the heatbed after printing. The hotend cools down after end the print, but the bed does not turn off.
I´ve updated to 065e, edited config.g to T1 and also updated to web 0.90.


After a dowgrade to FW 059e it works again.


Greetings

What do you have in tour end gcode? Is M140 S0 in there? If you have any G10 P0 commands, those would now affect the bed heater instead of the extruder/hotend, and that could confuse things.

Hi fstck,

here is my endcode:

G1 X2 Y190; park the machine
M104 S0 ; turn off extruder temperature
M140 S0; turn off bed temperature
M1

Please try firmware 0.65f-dc42. If the problem persists then please post a smallish gcode file that demonstrates the problem.

Hi dc42,

i have updated to 65f, web 0.90, edited config.g from T0 to T1.

Here is my testprint-gcode (start and end). The bed didn´t power of after print.

Thanks for the sample, I reproduced the problem.

This behaviour is a feature of the RRP 0.65e firmware that got fed into mine when I did the merge. The M190 command sets both the active and the standby bed temperatures to the value you give. I don't know why it sets the standby temperature, and there is a FIXME comment and query on that line of code. Then, when you execute M1 at the end, it sets the bed heater to the standby temperature - thus cancelling the M140 command you just sent.

I'll change this in my next release to not set the standby temperature when processing M190. In the meantime, I suggest that you don't use M190 to set the bed temperature. Use M140 followed by M116 instead. That way, the standby temperature won't get set. Alternatively, add command G10 P0 R0 after the M190 command, which should reset the bed standby temperature to 0.
