@TLAS said in Limit heater ramp rate?:

I need the power at maximum temperature to counter radiant heat loss, so running the heater at a lower PWM wouldn’t work.

Can you set a gcode Daemon job that will adjust the max PWM rate to the current temperature? E.g. every few seconds.

EDIT: It may confuse the PID but this may also we adjusted with the increased temperature.

EDIT: Another option may be to adjust the PID, for example, reducing the P value (?). Dave should know better.

The Zesty "founders" are still around and promising that parts will be available - we shall see.

Thank you for the execution,

I have two other printers with Duet Boards where I print slower and with much less acceleration.

I have not tested Klipper yet, but I am planning to build the next printer and run it with Klipper to have a comparison.

I printed the VZ Cupe at 100mm/s with 5K ACC of the outer perimeter.
Reducing the acceleration of the outer perimeter to 2K at 100mm/s has brought significant improvement.

In my opinion, I should also be able to select the speed and acceleration in the selection window for Input Shaper as the frequencies change at different speeds and accelerations.

@droftarts, @Phaedrux, It seems that I encountered an issue with the cable I initially used. I replaced it with the one provided with the panel, modifying one end to connect it to the Duet 3MB. The result is a perfectly functioning setup now.

Thanks a lot 🙂

Thank you very much for the quick response. You are a true life saver. Especially the life of the printer... 🙂
Ich modiefied the code a bit so that the head moves to the middle of the bed before probing. The rest was copy / paste. Thank you very much again. Joe

@jay_s_uk

Thank you for your reply.

@jay_s_uk said in Last Print Duration and Deleted Job Files?:

And no, its held in the object model until a reboot or the next print

That's a shame. Even with all the soundproofing I've installed my neighbour claims the printer kept him up all night one day last week even though the printer was running 24/7 all week.
I just wanted to check the speed settings of printed items (now removed/deleted), from when he said he couldn't hear the printer.
My soundproofing can be seen in the following thread;

@Legrand said in Duet conversion:

@droftarts Got it. It was the delta radius issue. I didn't think that would prevent the move, but, apparently it did. Thanks.

Movement cannot be computed if the rod length is less than the delta radius.

I got it now. I have my speed turn up to a point that I like it and it probes Z in the center of the bed like it should too. Thank you @fcwilt and @droftarts.

@fcwilt Yeah, I know about the queue. I dunno, I guess i just Assumed that it would not be utilized for homing calibration other such things.

WHY i guessed that... I do not know. A move is a move is a move really. 🙂

@br7408 Your the first person outside of work that knows what that symbol means. Nice to meet ya Chief!

What firmware version were you running on the previous board?

At this point I would suggest you update the firmware on the board and generate a new set of config files using the online configurator.

https://docs.duet3d.com/en/User_manual/RepRapFirmware/Updating_firmware

https://configtool.reprapfirmware.org/Heaters

And treat it like a new printer build and go through commissioning.

Have you been in touch with Modix support to help rule out anything electrical or mechanical?

@skhotso

The G30 sets the Z=0 Datum which is a good thing to do before doing any of the following:

before auto leveling the bed after auto leveling the bed creating a height map loading that height map

Now you can might get away with skipping the G30 before auto-leveling but not after. The bed leveling process can change things enough to require re-setting the Z=0 Datum.

The whole point of leveling the bed, creating a height map, setting the Z=0 Datum is to improve the results of the printing process.

So you can limit the G30 G32 G30 G29 S0 sequence to creating the height map and the G30 G32 G30 G29 S1 sequence when starting a print.

You skip G30 and G32 when homing Z as you have a Z endstop switch and can use that instead.

@R006 said in How to configure 3 Z motor on duet2 wifi:

@Phaedrux how ?

See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Motors_connecting_external
See the Duet 2 Wifi/Ethernet tab under 'Connection options' section in the above link.

If the drivers require no more than about 2mA @ 3V on the step, dir and enable inputs, then you can drive them directly from the Duet 2 WiFi/Ethernet Expansion header or CONN_LCD header. The Expansion header has support for 5 external drivers. The CONN_LCD header supports two external drivers.

You can't drive a stepper motor directly from the pins. You will need some kind of stepper driver, and probably a breakout board. See the Examples section lower down, too. It's all on that page.

@cosmowave I was able to print only with T1 on a dual head setup by deactivating T0 in Cura before slicing

@droftarts Thank you, this is very helpful! It will be easy to extract what I want to from that.

@fcwilt underneath the bed heater in direct contact with it. Will help with power consumption and excess heat in my workshop room.

@Pranayme said in Help with configuration:

@fcwilt Error was with the M906 command

Good job.

I know it was tedious but it worked.

I wonder how you do set the current for that stepper - clearly related to using the 1XD board.

Frederick

@dc42 Thanks David. I can wait 🙂
