One question: do you have a printer with multiple tools?

One suggestion: take the time to update to the current v3 firmware - there are many, many improvements and fixes. It involves some changes to your configuration files but it takes less time than you might think. I put it off for a long time only to find it wasn't that much work.

Were there I/O mapping changes from 2.05.1 to 3.3? We have an error coming up with regards to the LED Current callout is M42 P27 S100 but it says the P is too high.

Did you see this regards v2 to v3:

In RRF3, before you can use M42 you must create a GPIO port using M950. Then in the M42 command, the P parameter is the GPIO port number, not the logical pin number. Duet 2 supports up to 10 GPIO ports, numbered 0 to 9. No GPIO ports are allocated by default.

In RRF3, the F and I parameters are no longer supported in M42. Instead, use the F and I parameters in M950 when you create the GPIO port.

Example - RRF2 code:

M42 P3 I1 S0.5 F500 ; set Heater 3 pin to 50% PWM at 500Hz

Example - RRF3 code:

M950 P0 C"exp.heater3" Q500 ; allocate GPIO port 0 to heater3 on expansion connector, 500Hz

M42 P0 S0.5 ; set 50% PWM on GPIO port 0

Does each extruder have it's own Z probe?

@fcwilt We found the change logs https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x#reprapfirmware-30 and https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview, and are going thru them to adjust our macros.

No, it is shared between the primary and secondary extruders.

M375 ; Loads the grid matrix file (Heightmap)

Best not to load the heightmap before you do the tilt correction. So remove that from homeall and add it to your slicer start gcode instead so that the heightmap is loaded before a print.

Also don't call M584 inside of homeall unless you need to split and join drivers to axis.

Also, I don't think you need to use G30 S-2 at all. You are using G28 to home all, and that will do a G30 to set Z0 based on your probe trigger offset.

I strongly suggest you use the config tool to generate a fresh example config for RRF3. You can compare it to your current one and modify it to suit. But at least that way you'll be starting with the correct RRF3 syntax.

You say you have dual extruders, but I only see one E drive created.

What is the U drive?

The Config.g is for RRF 2.05.1 so it likely does not have the extra extuder defined properly for RRF 3.3

Phaedrux

Extruders are defined the same in RRF2 and RRF3. M584 E3:4 for example maps drivers 3 and 4 as extruders.

I have not dug into those settings yes as many were defined by Modix, but maybe for the single extruder only.

BStump

Well we have upgraded the firmware to RRF 3.3 and the config.g has the correct settings now.
