@Phaedrux Thanks mate, I am on the right track now, I can see clearly that the old M305 commands need changing to M308 and a few other changes.
The only thing that really concerns me and maybe you can advise is the last.
M98 PCONFIG.G
Error: Invalid Z probe type 4
Error: Invalid Z probe index
Error: endstop type 0 is no longer supported. Use type 1 and invert the input pin instead.

Ok so this is covered in the M574 command on the RepRapFirmware 3 overview.
My question is, is that a physical change or just a firmware assignment change to invert the pin?. Thanks.

Hi,
So I had some time at home and wanted to get a working version of RRF3.
Nows a good time to delv into the RepRap firmware being much more used to Marlin.
I appreciate there are lots of Macros and I will remove some where possible, but do they really prevent the detection of the second hot end if I define the bed size or stepper currents incorrectly.

Or is it a case that it would need to bug check the whole config before it will use the new config.
As the definition of the tools is in the "Pmachine_ktana_tools" then this is where I would look for an issue of not defining the 2nd Tool.

M98 Pmachine_endstoptypes.g ; set endstop types
Defines the Endstop type mechanical or IR.

M98 Pmachine_steppercurrent.g ; set stepper currents
Defines current to the steppers

M98 Pmachine_stepperspeed.g ; set stepper speeds
Defines speeds Jerk and acceleration

M98 Pmachine_axisdimension.g ; configure the axes dimensions
Sets the Min and Max axis Dimensions

M98 Pmachine_axissteps.g ; configure the axes steps per mm
Defines the number of steps per 1mm

M98 Pmachine_extruderstep.g ; configure the extruder steps
Defines the extruder steps

I believe there can only be 2 places where there is a problem.

Hi,
Thanks for taking the time to look into this
Duet 2 Maestro.
Old firmware 2.02
New Firmware Release 3.01-RC12
Duet Web Control 2.1.0
Printer M3D Promega
Core XY
Nozzles Dual K'Tana.

I know some of these will not be compatible with the latest firmware but I would like to start by identifying why both extrudes are not identified.

Hi Guys,
I thought the configs for my heater and hotends were contained in the "machine_ktana_tools.g" file.
However I now only see a single extruder in the Settings tool section, I am sure I have just missed something but this has worked well on older firmware. Any help would be appreciated. Thanks.

Phaedrux, thank for the help just some tuning to do now.

Great thanks for this, I will look into doing this tomorrow evening. I have just one question that is when using the IR Probe I get random measurements using it on a Glass bed, that's why i have always used the z probe switch setup. Even if only selecting one of the probes if the Z=0 is not the same on both will this still not flag up an error. Given that one is on the right of the print head and one on the Left Thanks!

Thanks. Machine M3D Promega. Its a CoreXY Motion Platform. Files attached again thank you for looking into this for me.3_1563738051917_machine_zprobe.g 2_1563738051917_machine_zendstop.g 1_1563738051917_machine_bedmesh.g 0_1563738051916_machine_axisdimension.g

Hi Phaedrux, Thanks for taking the time to look into this for me, the original macros were setup by M3d for my printer and still getting my head around the M codes.

Ok thanks Veti, I rolled back to 2.02 and have managed to perform a mesh bed and calibration with no issues. I will hold off on updating for now as I have not been able to get anywhere near a reasonable Mesh from 2.03 or 2.04. As was mentioned in a previous post the difference in the IR and Switch heights throws my calibration out I don't get this problem in 2.02.

Currently on 2.04RC1 (2019-07-14b1)
Want to roll back before IR probe and Z Switch needed to be linked, believe it was introduced in 2.03. its causing the error "Warning: the height map was loaded when the current Z=0 datum was not determined probing. This may result in a height offset"
I cant seem to get a level bed anymore using the G30 command as a single use at the beginning of the print.
For some reason my height.csv is not updating and still shows 5 days ago no matter how many time I run the Mesh map.
If I can roll back no problem thanks.
