Missing Buttons

[wijnen]

Reset printer would be good. As a workaround, you can disconnect/connect (at least works for me with Sprinter firmware).

Instead of a button for M84, it would be better to send it when it is required. That is:

• add it to end.gcode.
• send it after any movement button is used.

For the rare case that you then still need it manually, you can just type it in at command input. I agree that I currently have to type it there quite often, which is annoying.

I need it whenever I have moved the axes manually so I use this button very often in pronterface etc
Send it after every movement would be possible but quite an overhead ...

[wijnen]

No, not after every movement. That would not only mean overhead, but also mess up the build. I mean send it after any manual movement (so, with a button). Given the slowness of the user clicking the button, there's not that much overhead in that case.

However, it might be required to build in a short delay before sending it, to allow the motor to actually reach the new position.

[hurzl]

I often press a button repeatedly so I don't know how it will affect this...
A delay of a few seconds maybe? Makes it a bit complicated

[wijnen]

Multiple button presses will be at least 100 ms apart from each other (or in any case, a 100 ms delay isn't a problem). The settling delay that might be required shouldn't be more than 10 ms, I think. You can't click your button 100 times per second. ;-)

[hurzl]

I can click it before the previous move has ended. Then an M84 would be useless

[wijnen]

It would be useless, but also harmless. The firmware will finish the in-progress move before using the next command. So it will anyway finish the move before starting the next move. disabling the motors in between the moves for a microsecond is no problem.

I've tested a one-line patch which works fine.
After line 490 of src/model.cpp, add:
SendNow("M84"); // disable stepper motor power

[hurzl]

That's not very good. Before, multiple movements where added continuously, now I have a break between them.
It breaks the acceleration of the firmware

[hurzl]

Reset does not work by disconnecting and reconnecting for example while it is extruding 150mm(!).

The values of Purge amount and Temp should be saved to the settings too
