@ViralTinker said in At what CPU temperature and active cooling ?:

CPU temperature is it something todo with as reference for stepper drivers?..

Not directly, however when the stepper drivers generate heat, they will heat up the CPU. The stepper drivers generate temperature warning separately, but only when the driver chip temperatures exceed about 100C.

The CPU generates some heat of its own, so don't be surprised to see it rise somewhat even when no motors are energised.

@ViralTinker said in Thanks!!!:

I thank you to 😉

But Start using/calibrating/get used to duet is not easy compared to Marlin.Hopefully I will overcome my hurdles

Thanks

Marlin is difficult too until you are used to it.

Thank you!

@deckingman said in Dual Z tilts after time (fast):

@AS-3D-Druck Starting with the print head in the middle step through your homing fie one line at a time but you can ignore the Z axis for now. So send M913 X50 Y50 to reduce the motor currents. Then send G91 to set relative positioning. Then send G1 S1 X-500 F4000 and tell us if the head moves to the left as it should or does it do something else?

Ok maybe i found the Issue here:

; X G1 S1 X-500 F4000

I had to send 3-4 times this command until it started to move to the min point.
Bevore that i heared only a tock after i send the command.... like there was already something that the stall detection noticed.

I don't know my Motors are rated for 1.3A and i set them to 1A and reduced it to 50%.
Now i played with M915 and increased the S Value from 3 to 8 to 10.

It looks like that was the Problem.

Thx alot for the help and i will try my next print with this new "Setup". 😊
You're Guys are awesome. 👍

@deckingman
Thanks for your reply!

Since I changed my old aluminum block to a wew cartridge type copper one, I need to buy a reliable cartridge. I wanted to bear down on the quality side, I just could not imagine why do people buy the pt100 when it has many problems (like the one You experienced) and it needs extra cabling and hardware, whereas they could just go for the pt1000.
Since a quality cartridge thermistor (with known values...) is comparable in price with a pt1000, I decided on the later one, and just wanted some comfirmation. Thanks everyone for the valuable info!

Or this one:

https://github.com/DanalEstes/DuetMonitor

It is a fork of someone else's original work; I did change a fair amount, and can certainly answer questions about how it works.

At the same time. @Willl point about http://The.printer.local/rr_status?type=1 really is the whole thing... that will return something like:

{"status":"I","coords":{"axesHomed":[1,1,1],"wpl":1,"xyz":[0.000,0.000,615.910],"machine":[0.000,0.000,615.910],"extr":[0.0]},"speeds":{"requested":0.0,"top":0.0},"currentTool":0,"params":{"atxPower":0,"fanPercent":[0,100,0,0,0,0,0,0,0],"speedFactor":100.0,"extrFactors":[100.0],"babystep":0.000},"seq":0,"sensors":{"probeValue":0,"fanRPM":0},"temps":{"bed":{"current":20.1,"active":0.0,"standby":0.0,"state":0,"heater":0},"current":[20.1,19.5,2000.0,2000.0,2000.0,2000.0,2000.0,2000.0],"state":[0,2,0,0,0,0,0,0],"tools":{"active":[[0.0]],"standby":[[0.0]]},"extra":[{"name":"*MCU","temp":33.0}]},"time":1776413.0}

The "status" key gives you most of what you asked for in your first post. At the moment the above sample was requested, the printer was "I" - Idle. It could also be: P=Printing. S=Suspended (paused). And so forth.

You do need to poll it. For Home Auto, once a minute should be just fine.

@dc42 I get the idea, but i'm having a hard time picturing it. Once it's released, how did it pull it back up?

@dc42 Thanks... will do!

This is a 3D Potter Super 9. All of the axes use a worm gear reduction on closed loop steppers. The steppers have settings for pulses per rotation; it may be possible for me to get the same movement with fewer steps by changing multipliers.

hi i think i solved it. I replaced the 24volt power supply and by testing I see that it doesn't create any more problems. the cause was something inside the power supply that at the time of the shutdown created a power return ... thank you very much for the help. the contact returns again for the simplify 3d speech and if I can then I want to create a help guide.

@deckingman
Thank you

Your M558 command indicates that you have a BLTouch. You should remove the M98 Pdeployprobe.g and M98 Pretractprobe.g lines. Also, check that your deployprobe.g and retractprobe.g files are set up correctly for BLTouch.

You are right. I will calibrate the z height.
Thx

thanks to all! after another exhausting search, I confirmed that it was in my bed.g......a M208 Y240 I planted a long time ago to accommodate one of the experimental tool changer setup....I didn't have this problem initially because I asked the slicer to G29 before each print, but lately I've begun to manually probe the bed by pressing that 'auto bed compensation' button, which is a G32!

send M208 without parameter is a godsend...thanks dc42!

I am creating a new thread for this but I currently have it plugged into the E0 endstop.

Given that settings in Duet are completely dynamic, and probing the bed on a delta is really a series of commands in bed.g, it would seem there are several ways to accomplish what you want.

Expand/contract M666 B just before the commands that probe on the "side" where the probe is offset, and then put it back after those commands.

Just leave M666 B at the larger setting, and hand-edit the commands in bed.g that would have a problem.

There's probably others that I haven't thought of, by utilizing dynamic settings at the appropriate places in Bed.g.

All fully automatic, and no Duet/RepRap firmware changes needed.

@rmilyard The laser version is a bit more limited in the materials you can use with it. From the product page:

Note: The Laser Filament Monitor is sensitive to the filament type used: it has proved less senstive to PETG of certain types. Please read the documentation for more details.

The magnetic version is more adaptable, but more expensive. Unfortunately, I don't have either of them! You'll have to ask for feedback from other users which they prefer.

upgrade to 2.05RC2 as RC1 had a bug where it wasn't communicating correctly with DWC.

Yes, a switch on the carriage and a switch on each dock wold be ideal. The carriage switch would confirm that a tool is loaded, and the dock switches would indicate which one it was.

I've been working with my tool changer yesterday and today. I've managed to get stall homing working on the coupler, and I am developing a set of configuration files for RRF3 on Duet 2. I'll also be moving the origin to the centre of the bed, which is what I use on all my 3D printers.

Samoan! Nice. @froma1976 Please post your config.g.

An axis will not move until it is homed (or the gcode to override "move without home" is issued). An extruder does not home.

An extruder will not move until its associated heater is above the configured temperature (unless the gcode to override "cold extrudes" is issued).

Both axis and extruder can be specified in G0 or G1, and if other axis/extruders are included in that same command, "coordinated linear motion" will occur (moving each at a speed that ensures they all reach their respective final points at the same instant in time.) So no difference there.

There are probably more differences and similarities. These are a few that came to mind.
