RepRapFirmware 3.0 is released!

@DaBit I don't have that problem with my bed heater which is mains powered via SSR but I'm currently the other side of the world to my printer so can't say how it's configured. But IIRC, the default frequency for a bed heater is 10 Hz.

Please confirm that you are running version 3.0 (not beta or RC), and post your config.g file, homeall.g file, deployprobe.g and retractprobe.g files if you have them, and any other files that homeall.g calls.

@deckingman: I think RRF3 is a lot more generalised / has a lot less notion of specific pin functions than RRF2. It would not surprise me that a 'create heater output' M950 does not differentiate between different kind of heaters. Which is, IMHO, a good thing.
But the flipside is that the PWM frequency is also default, and probably quite high. Which does not work well for SSR's and especially the zero-crossing types; you can turn them on or off 100 times a second maximum (in the 50Hz EU). Thus, if one uses a 10Hz PWM frequency, the power can be regulated in 10% increments only, which is already not very high resolution. With a 500Hz PWM frequency the triggering of the SSR becomes a statistical function; a higher duty cycle makes it more likely that the SSR triggers at the zero crossing. It will regulate, but more in a bang-bang like fashion than a nicely controlled proportional fashion.
Since the thermal time constant of my heated bed is so large, I could easily get away with a 0.1Hz PWM frequency, but that increases thermal stress (wires in the heater heating up - cooling down - heating up - cooling down...), so 2-5Hz is a better option.
Which made me search for the limits on PWM frequency, which I did not find.
@Adamfilip : I got those 'G28 SetPosition called when DDA ring not empty' messages too after upgrading to RRF3, and in my case it had something to do with the endstop switches being setup in the wrong polarity. They were already triggered when the homing move started.
After fixing this, the message went away. -

In case it helps: here is my config bundle, or at least the latest backup: https://nextcloud.icecoldcomputing.com/s/YQo7Z7iEqfzDcXF
When I invert the endstop polarity in de M574's at line 40-41 of config.g so that they are triggered when the printhead is nowhere near them, I also get this DDA ring error. It also shows up in the eventlog (also included in the ZIP), but no more information is logged there.
RRF is the stable release ((2020-01-03b3), board is Duet2Wifi 1.02 or later, DWC is 2.0.4If you want access to the board to run tests or do some debugging, just ask and I will setup temporary SSH access that allows you to tunnel to the Duet.

This depends on where you have the probe plugged in, if it's the Smart Effector and plugged into the z endstop connector, that would be correct. But, usually it's plugged into the probe connector next to the expansion header. In that case what you put would be incorrect.
If the probe connector, it should be

@bulka is this a Duet Wifi or Duet3? and Am I right in thinking it is a smart effector?

@DaBit I'll check my settings when I get back home in 8 days or so. I suspect that I'm using 10Hz because that is what I've always used. IIRC that figure of 10Hz was chosen specifically to suit SSRs. However, do not confuse the PWM frequency with the mark-space ratio that is PWM itself. And also, don't forget that the thermal mass of the aluminium plate acts as a huge damper to the conduction of heat through the plate, which makes the PWM frequency largely irrelevant.

You have a bed.g file?

The documentation for converting M558 to RRF3 is a bit confusing in regards to the "I" parameter. In particular, it doesn't say anything about it (in that section)
https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_M558
As well, the gcode wiki page also seems to imply that "M558 I1" is valid (https://duet3d.dozuki.com/Wiki/Gcode#Section_M558_Set_Z_probe_type)
"All of the above for RepRapFirmware 2.x relates to RepRapFirmware 3, except the following:" (and nothing that follows makes mention of the I param.)
Yet, from reading this thread, I get the impression that RRF2:
M558 P8 I1 R0.4 F300 H3does not work in RRF3 as:
M558 P8 R0.4 I1 C"zprobe.in" H3 F300and instead should be written as:
M558 P8 R0.4 C"!zprobe.in" H3 F300 ; I1 removed, ! prepended to zprobe.in
Edit: I accidentally left the "I1" in my 558 after converting, and had the ! before the pin. The result apparently was a double inversion. Removing the I1 and leaving the "!" made everything seem to work.
So ... which is the proper way?

Duet2 wifi h/w version 1.04
Printer is a normal delta (with 0.9 degree steppers)
Firmware is the first general release of RRF3After starting my first print with RRF3 on a Duet2 WiFi, I'm seeing a LOT of hiccups using an identical configuration to what I used with RRF2 (where I only rarely saw a hiccup.)
For example, 45 seconds after sending "M122", I sent M122 again and saw "Hiccups: 423(0)"
Measuring it at one point, I got 161 hiccups for a travel move of around 80mm.
The hiccups seem to be only after travel moves which are configured at 200mm/sec in my slicer. Yes, I could slow this down and probably get rid of the hiccups, but the point is that I did NOT get hiccups with RRF2.0.5 with the exact same gcode file.
The speed related lines in my config.g are directly copied from my RRF2 config.g, as well as the stepper config. I've included them below:
