If the X or Y axes are homed then you turn the ATX power off, if you issue a G1 H1 against X or Y, the axis gets marked as homed even though the power is still off.

That should happen if and only if the X or Y (as appropriate) endstop switch is triggered when you send that command. I agree that it would be better just to reject the command.

No worries. Not a big issue.

Heh, just as I said that... I just turned ATX on and tried to do a homeall and got ...

Not sure if this has already been reported. When I set an offset for a tool and then switch between selected and unselected state the X/Y coordinates are ajusted correctly in DWC. But the behavior of the displayed Z coordinate is strange. Sometimes it is not changing at all, sometimes it changes when a move is executed. Nevertheless just the displayed value seams to be wrong. The offset is taken into account as it should be.

By any chance, does the change in value correspond to the correction applied by the heightmap?

We've used the RepRapFirmware 3.01-RC1 on Duet 2 for Five Bar Parallel SCARA configuration. It produces some sort of jerking when passes through 0 of thetaR (see the picture in https://duet3d.dozuki.com/Guide/Five+Bar+Parallel+SCARA/24?lang=en). Could you suggest how to eliminate the jerking?

TC

@gtj0 good idea, but I am not using any height map yet. Also wouldn't the heightmap just apply an offset to the coordinate in both cases? The strange thing is that it is sometimes not changing at all when selecting the tool.

@dc42 said in RepRapFirmware 3.01-RC1 released:

You don't need a Z endstop if you have a Z probe. Delete your Z endstop in config.g and use just the Z probe. Make sure that your homing files use a G30 command to home Z, not a G1 H2 Z move.

Thanks. That's much simpler.

Any thoughts on the chamber issue? Can I just allocate any random pin to the heater or will there be a check on whether it can actually perform as a heater?

spllg

unsure if this is related to 3.01-rc1but i feel, it might:

tried to configure my ed3 v6 as

M308 S1 P"temp1" Y"thermistor" B4725 C7.06e-8

which resulted in a displayed temperature of -273.1C.

M308 S1 P"temp1" Y"thermistor"

seems to result in a temperature reading which is ~20C too high around 200C - at least i'm unable to print pla at temperature < 215 because it would not flow.

what should i do?

After sending that first command, send M308 S1 to see whether it reports the correct parameters.

I can't remember whether you can use any pin or it has to be PWM-capable. But your alternative is to use conditional GCode. Don't create a dummy heater, just a sensor. Then loop until the sensor temperature is high enough, e.g. within 5C of the temperature you have set for the bed heater (if your sensors agree that closely).

Items "t" do not work.

OK. Definitely interested in trying that, though the benefit of the chamber definition is lost (i.e. I can see the sensor temp displayed clearly in DWC - but maybe there's another way to add the sensor to the UI?).

Here's what I tried:

echo "starting"
while true
	if heat.sensors[6].lastReading < 30
		echo heat.sensors[6].lastReading
		break
echo "bed temp reached"

I tried this as a macro and a gcode file, and neither work. In fact, I think adding the additional echo within the if body and then running the job caused DWC to go into an infinite-reboot-loop. If this isn't the right way to test code, is there an alternative?

I realise the logic is upside down by the way. I've been flipping the >/< while testing.

Just to confirm this is the right sensor to test:

I think what's happening is that the loop is taking up all the processor time. I'll fix this in RC2. Meanwhile, try putting a 1 second delay (G4 P1000 command) in the loop body.

Is there an update for the expansion board as well?

Try the one at https://www.dropbox.com/sh/3azy1njy3ayjsbp/AACquxr2m00eV568RZg5QG5wa?dl=0. You might need to use the copy of RRF there too.

SpoonUnit

@dc42 said in RepRapFirmware 3.01-RC1 released:

Yep. Sorted. Thanks!. I did wonder whether it was just going to get stuck that way. So, the second pause does fix it, and perhaps that's sensible anyway. You're in control about how much to wait between cycles. I guess if you're going to fix it at some value, that value could be set by another GCODE before entering the loop perhaps.

The short piece of code does generate an interesting result on the progress bar

SpoonUnit

Actually, now I'm a bit confused ...

This was where I (stupidly) put the pause ...

while true
	if heat.sensors[6].lastReading > 30
		G4 P1000
		break

But it worked anyway (?), so it paused even without the sensor having the right value.

Also PrusaSlicer isn't terribly excited about the GCODE ..

!!!!! Failed to process the custom G-code template start_gcode
Parsing error at line 18.
if heat.sensors[6].lastReading > 65

SpoonUnit

It seems Slic3r uses [] to denote variables, so if they're found, it immediately tried to process and then fails. I wonder if an alternate form can be made available along the lines of:

heat.sensors.6.lastReading

This then doesn't trip the error. For now I can post process to just put the [] back in.

why not use the macros provided by RRF to do start/stop stuff?
