Hey guys,

Can anyone explain to me the purpose of M556?
I looked at the reprap website and I don't really understand this:
"Though with care and adjustment a RepRap can be set up with its axes at right-angles to each other within the accuracy of the machine, who wants to bother with care and adjustment when the problem can be solved by software? This tells software the tangents of the angles between the axes of the machine obtained by printing then measuring a test part. The S parameter (100 here) is the length of a triangle along each axis in mm. The X, Y and Z figures are the number of millimeters of the short side of the triangle that represents how out of true a pair of axes is. The X figure is the error between X and Y, the Y figure is the error between Y and Z, and the Z figure is the error between X and Z. Positive values indicate that the angle between the axis pair is obtuse, negative acute."

So my questions are:
–When would you use M556?
--how does this relate to the z-axis?

Thank you!--Hunter

hey dc42. I have a bltouch smart and doing mesh bed compensation on duet wifi. Why is my z-axis not moving like in the video on the first page of this thread? Does mesh bed compensation and autobed compensation cause different z-axis behavior? I also have two steppers in the z-axis connected to ZA and ZB on the duet wifi board. lmk, thanks.

How is it behaving then?

It stays stationary unless there is a layer change. What I noticed on the other video is that the z-axis steppers would move back and forth based on compensation needs. Does this mean my bed is just perfectly leveled (highly unlikely)?

@dc42:

With that date, I think it could be either. The version is printed on the back of the board.

dc42, I am confirming that I did get v3.0 of the Panel Due from Filastruder. Thanks!

@dc42:

The IR probe results have one corner point much lower than the rest. There must be something in that corner to cause that, or perhaps you are probing too close to the edge.

I am pleased to announce that version 3.0 of the Panel Due display controller has been shipping for a little while now. The changes since version 2.0 are:

• Processor core is now ARM Cortex M4 instead of M3

• Processor flash memory, RAM and clock speed are all DOUBLED! The extra speed makes for a snappier response.

• In the future, we will be able to support firmware upgrades via the Duet

• If you have a Duet Ethernet or a Duet WiFi revision 1.01 or later and the PanelDue will be close enough to the Duet, you can now use just a 10-way ribbon cable to connect them together. The 4-way connector is still provided for users who wish to site them more than about 300mm apart.

• I have reduced the RRP (recommended retail price) of the basic controller board + connector kit from £30 to £25, and reduced OEM and distributor prices too. I am pleased to report that the main PanelDue distributors (Duet3D and Filastruder) have reduced some of their prices in line with this..

So if you were thinking about buying a PanelDue, there has never been a better time! You can buy the PanelDue controller board by itself direct from me at escher3d.com (also from duet3d.com and Filastruder), or a complete kit including screen and cable from duet3d.com or Filastruder.

The firmware source code is common between all versions, so users with older versions of PanelDue will still be able to get firmware upgrades.

Version 3.0 has been designed to be compatible with enclosures designed for version 2.0.

dc42, if I bought my paneldue from filastruder on sept 13, 2017 did I get the version 3.0 or 2.0?
