The M557 command should normally be put in config.g not in bed.g. If you put in in bed.g then the grid won't be defined until you run G32.

Firmware 1.19 will include manual delta calibration and mesh bed compensation facilities, supported by new features in DWC and PanelDue.

The way it has always been done is that Z-up means head further away from the printbed. Just as a positive z-coordinate in gcode moves the head up and away from the printbed.

How about 7inch screens?

Can you have the locale button open a scrollable dialog box (like we have for selecting g-code files)? that way you can have as many locales as you like.

Do you still need a Spanish translator? I can help with it 🙂

Pressure advance doesn't work by shifting the phase of the extruder acceleration. What it does is to add a term to the extruder position that is proportional to the extrusion velocity. This works on the assumption that the back pressure is proportional to the extrusion speed, and the compression of the filament and the lag of the extruder motor are proportional to the back pressure. Whereas in reality, the motor lag is proportional to the arcsin of the back pressure.

This is essentially what the "lookahead/planner" in the firmware already do. The jerk or instantaneous velocity change is the setting most related to this. The planner looks at the velocity change vector (dv) and determines how much it needs to slow the head down in order to be within this parameter.

This is a big problem for 8 bit controllers (obviously the Duet is 32 bit) as their move buffer often runs out on fast machines, especially when doing circles. In those cases, since the planner has no moves to compare the current velocity to, it comes to a complete stop at the next point and then picks up again from there.

You can type in the temp you want in the box.

The filament movement part of this request is in hand with a filament sensor we are working on. It obviously requires more hardware as well as firmware.

Filament diameter is rather a specialist requirement because good quality filament is very consistent these days. It mainly the guys who are rolling their own filament who need it.

Awesome, thanks! 🙂
