There is a paper here:

http://www.ambots.net/user/pages/03.technology/_publications/chunk-based-slicer.pdf

That describes, amongst other things, a slicing strategy for "cooperative" printing.

May be of interest.

M605 is not supported according to the documentation.

I think what you are looking for is here:

@sean said in Closed Loop Control of Stepper Motors with Rotary Encoder:

What does "PanelDue has a hardware option to add a rotary encoder, but it's not yet supported in the firmware." mean from: https://forum.duet3d.com/topic/2613/external-rotary-encoder-with-duet-wi-fi/8

That encoder is usually combined with an LCD and is used for driving a GUI on most printers. Nothing to do with closed-loop control.

What is the complete M915 line you are trying to use?

You probably just need to tweak the z value in your g31 command.

Try making it -0.2. There are better ways than just guessing but that should be enough of a change to notice if things are going in the right direction.

What temperature are you trying to print at? What kind of extruder is it?

Your M208 line in config.g is telling Reprapfirmware that the minimum z position is 320. Calibration ignores this setting but when you go to print z is well below 320, so the move fails.

I'd change that line to something like

M208 Z-0.1 S1

The gcode file is the one that cura produces. Open it in notepad and copy the first 20 lines or so.

There is nothing stopping you using 12v. I think 24v is advantageous for 0.9degree steppers but it's by no means necessary. Is there something in particular you think you need 24v for?

Can you post a small section of the gcode you are trying to print, up to and including the first few G1 lines?

I'm wondering if your slicer has its origin misaligned with the forward or similar.

@adavidm Or this one, for temp and pressure:

@nophead said in Pressure advance input from instrument measurement:

Large commercial extruders manage to do that somehow

Could something like this work? I dread to think what it costs with the amplifier, readout, etc.

Doesn't S0 mean disabled?

@vapvap said in [SOLVED/(+/-)UNSOLVED ] Heated bed PID auto tune failed.:

@dc42 Unfortunately, I have again and again fail my calibration.
It seems to me that I spend too much time on it.
Maybe it will be easier to install PT100 / Thermocouple?

I don't understand what you mean by "fail my calibration". All you need to do is add M307 P0 A191.5 C1032.9 D5.0 to your config.g file, and make sure that there isn't a similar command in config-override.g that will override it. Then heat the bed up to normal temperature. If you see oscillations then increase the D parameter. You can do this live, i.e. send the M307 command with different D parameters while the bed is hot, until you find a suitable value.

It looks like @vapvap is setting the parameters using M307 and then running an autotune with M303, thinking that that is needed. Possibly a language barrier problem?

@gnydick

Did you re-slice the file using absolute extrusion too? If not then you need to.

The reprap.org page is a good place to start:

You have to change the port and protocol. You've probably done both, as the "Telnet" label is pretty prominent, but Putty does default to SSH IIRC and it's easy to overlook.

Is your windows client defaulting to ssh?

@Catalin_RO I don't think that is true with RRF unless you are in CNC mode. G0 and G1 are identical in 3D printer mode IIRC.

Ah, OK. I know S1 behaves differently on Linear Delta, which is why I asked.
