@chrishamm Thanks for reporting back! I actually also had the problem of another chromium window opening over DWC, that is fixed. Will check if the config loading is fixed too.

@zapta Yes. Set your fan to 0% at the beginning of pause.g, and back to 100% at the end of pause.g.

@kareka set your tool up to have your part cooling fan specified as part of the tool and then the M106 S255 should work then that tool is selected:

e.g. (adapt this for your existing M563 command):

M563 P0 D0 H1 F0

Thank you very much @dc42,

I didn't know what else to look at, it was driving me crazy.

This is what I did just in case, it's correct? I added the S command as well.

M584 R0 S0 X0.0 Y0.4 Z1.0 U0.1 V0.2 W0.3 A0.5
M584 R1 S1 E1.1:1.2:2.1:2.2:2.2

When an axis is set to rotary mode, what happens? would it also not respect M208? in which cases should it be used? If I use a conveyor base should I treat it as linear or rotary? This is my next project

Where can I find section 2.1.2.5 of the NIST GCode standard?

Thanks

@davidson you would need to modify the firmware to do that. Execution of each motor command is done in an interrupt handler, which is not an easy place to add logging code. However, once moves are finalised by the Prepare function, they are not touched until the interrupt service routine executes them (except in the case of power failure), so you could add your logging code there.

@t3p3tony The LED's are controlled individually and not connected to other outputs. Mounting options for a diy'ed PCB with mosfets is very limited, hence I'll probably use the 24V heater outputs with larger resistors in series to the LEDs. The Duet is mounted directly next to a larger fan, so cooling these resistors shouldn't be a problem. Thanks for your advice!

@dc42 Here's the response I got, looks like all boards are running on the same firmware.

The only other thing to beware of is that the motor is kept below the speed it can start instantly from.

If it stalls or "slips" at above that speed, it may never restart, as the acceleration ramps that allow higher speed only occur when the control system starts & stops the motor.

@t3p3tony

yes i use that Parameter, in my case it's 255.
the R Parameter corresponds to Max Laser Power so in case it would be 100
on S100 the Laser Powersupply has a 100% ON PMW Signal

A Max Value / Restriction Parameter would be good in M452!!!

I wanted to use a normal Slicer, in my Case Prusaslicer with a Normal Printerprofile.
the Only Thing that needs to be done is to wipe the Platform before every Layer,
to Add the Powder. and a Gcode Edit need to be done.
for example, to Convert "G1 X100 Y200 E0.055" into "G1 X100 Y200 E1 S100"

It should be A Gcode with a E1 Signal to Enable the Laser and a S*** Signal to
set the Laserpower for each specific G1 move.

i'm developing a special GCode Editor (Windows and Mac based) to set Laserpower for Raft, Supports, Infill, Shell's.
I Want to make it as easy as possible if the Printer is Ready for a potential Fan Out in the Future.

and i don't want anyone to use a Overpriced Slicer for that purpose....
(for Printers without Galvo Head)

@anna-rolcova please post your config.g using the </> in the text formatting to make it easy to read.
Also provide some more information about which temperature sensor is not working. How is the heater connected, what heater etc

@t3p3tony said in Bed heating starting with lag:

What is the rating of the heatbed you are using?

It doesn't say. It's a 24V PCB bed that came in this kit, but I can tell you that the power draw from the mains during bed heating (according to my Gosund P1 smart power socket) is ~400-430W with a 24V PSU and a Duet-only 5V PSU. I guess it's rated at about 350-400W.

While the heater is in the initial flashing phase, is the mosfet getting noticeably warm to the touch?

Is that the one right next to the fuse and the bed heater terminal block? If so, it stays cooler than my body temperature until the bed actually starts warming up.

Another test you could try is temporarily switching the bed heater out for your extruder heater. swap the temperature controls as well and still control the bed heater as a bed. the idea is to see if it behaves the same way with a different (lower) load.

Got it. I can't do that now, but I will try soon.

Thanks for helping me debug this!

@frcwifiduet You could use deamon.g to move the camera on layer change, job.layer shows the layer.

@achrn Yes, and the fan speed is so low it doesn't really matter if they are on on or not. It makes no difference. Estoy muy contento 🙂

Can you elaborate on what you mean by the configuration settings for the pullup?

@t3p3tony Just updated the firmware and I can confirm that the MAC is correct. Thanks

@aprz I don't know if you can even do that. Guess it depends on which board you have.

However I can't say if it would help but I think it's a hard way to go to fix something that might be fixed with other motors.

I should have changed a long time ago but I was convinced it was an "upgrade" even though I see now that those motors do not belong on a 2.4 IMHO. The OMC BOM motors are quite affordable.

I hope you can make it work better.

60 mm/sec on a Voron, or really any good corexy, is painfully slow 😉

Cheers

@t3p3tony ah, ok i got it, thanks

@t3p3tony

M208 reports the machine limits regardless the actual position. These limits that are -8.5:88.2 (Z axis).

If I move the nozzle down to Z0 at X0, Y0:
M114 reports user position as Z=0, machine position as Z-8.5 (which is the limit), and the bed comp value is 0.000. The nozzle is well positioned (almost touching the bed)

If I don't lift the nozzle and move to a position where the bed comp is -0.2 (that means the bed is lower in that point)
M114 still reports user position as Z=0 (because i didn't lift it), machine position still Z-8.5, and bed comp. is -0.200. However, the nozzle is not touching the bed as it should, it is 0.1mm above (it compensates -0.1 instead of -0.2).

I can't run more tests until Thursday, but I will try to provide more info about the behaviour when possible.

Thanks.

Thank you for your help. I think I have it working. Yes, the F7 was already defined as a fan and that stopped the fan. The servo did work on the endstop pin, but the fan stopped. What I did in the end was:

M950 S0 C"duex.pwm5" ; assign GPIO port 0 to pwm5 on expansion board, servo mode

and use:
M280 P0 S80 ; set 80deg servo position on GPIO port 0
to move the servo. This is all very new to me, thank you for your help.

@tuomas apologies for the delay in the reply. As @oliof has already said this is totally do-able. And the actions on pause and other triggers are defined by macros you write so you could (for example add a trigger on material low if you wanted that came to a graceful stop.
