@Veti said in Maestro with RRF3:

M950 S0 C"zprobe.mod" ; create servo pin 0 for BLTouch
M558 P9 C"zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
you will need to manually edit config for now.

That's all correct. We'll change configtool to allow zprobe.mod as the PWM control pin. @PaulHew , thanks for reporting this.

@dc42 Thank you Very much, David, that’s what I was able to realize, once I monitored arm movement. Surprisingly, the same printfile executes properly on my Ultibot DV300, however I see the print head drops a little while waiting for nozzle to heat.
Currently, trying to properly setup QuadFusion printhead, but I will start another thread.

@DeltaCon said in Delta experts: feedback appreciated:

@bartolomeus, Thanks, looks good!
I certainly add the wish for a 4th axis and flying extruder to my build-wishlist!

Graag gedaan.

@bartolomeus said in Delta experts: feedback appreciated:

@dc42 The rail I am using for the 4th axis is too short, 400mm(build height is 340mm). It was a spare I had lying around. Is there a way to limit the movement of the 4th axis?

No, like the other 3 towers it will move as far as necessary to keep the correct distance from the effector.

Actually, I followed your advice (very long rod length) from another thread (z tracking camera) and now the 4th axis only follows z height and doesn't adjust for the distance between effector and extruder. It's a temporary fix untill the longer rail arrives.

@PaulHew said in Information difference between DWC and 12864 display:

BTW as it gets near to the end of the print, the % difference has reduced. 90.7 DWC to 89.2 12864

This is expected, because as you get close to the end of the print, all the estimates converge towards 100%, unless the firmware has mis-read the filament usage of number of layers in the model.

@sinned6915 said in Ammeter to measure hotend output?:

maybe i should have introduce more to this-

i am getting random 'Heater Fault" reporting.
It does not show up onthe GCode console
the print does not pause either- the heaters are still on and the print is still going.

the false positive is just as bad as a real one in my mind.

Have you run M303 heater tuning? https://duet3d.dozuki.com/Wiki/Spurious_heater_faults_and_how_to_avoid_them

The frame is thick wall steel square tubing with a pad welded to one face. That face was machined flat with the bearing blocks mounts and other features all in one shot.

I’m using a E3D Volcan with a 1.2mm nozzle and 3mm PLA for now.

We had a project planned for this that has since dried up so for now we’ll just be using it as a general printer.

@zapta said in Z probes compatible with BuildTak magnetic system:

This works well for those advertisement fridge magnets, they stick only with business details visible.

the creality magnetic bed looks & feels very similar to fridge magnet

Apropos magnetic beds, some are advertised as 'high temperature' and should not permanently loose the magnetic properties when exposed to higher bed temperatures.

I tested creality bed for 85C ~50 hours so far and 110C ~10 hours and it did not lose the magnetic properties ..

some Nd2Fe14B magnets I tried before to hold my metal sheet would weaken at 85C (petg) and lose magnetic properties almost completely at 110C (abs) so I was weary about usability of the creality bed for anything but PLA but the magnetic part looks like have no issue with it (there are other issues with ABS not sticking ok and PETG not releasing and tearing the bed) ...

anyhow, it does not affect the bltouch 😄 ...

Ha! Why do I have my M208 set to Z-780??

🤦‍♂️

This would have saved my buns twice now.....I never even saw that.

X and Y are set correctly...go figure.

Been working on this beast sporadically for almost a year...should be printing this week finally. Mind the mess and dangling wires!

Sounds like you need a PID controller on the pellet feed (not gcode).

You need to run M122 after you have done some moves and had the problem.

Thanks everyone.

I will try the US unit.

@p1ngb4ck I believe there is an 8.5 mm height difference between the V-6 and the volcano

@DocTrucker The Z-nuts are not adjustable on this design, maybe it looks that way with the metal by the endstop but that's only a spacer for it.

Could someone help me to find some neat solution for partcooling?
I've seen a design on Thingiverse that was made for the extrudermount that I have, but that was before I even considered getting one of those so I didn't save that and now I can't find it...

Okay thank you all very much, that did it.

@Veti

The Ultimaker 2 got this positions in his Original Firmware, i only copied them.
Thanks for the response

@PaulHew said in Using different E step values for the different filaments I use?:

M221 is the same, i think, as flow rate within the slicer.

iI has the same effect, i.e. scale the calculated or requested extrusion by a factor. M221 has the advantage that you can do it at the start of the print or on-the-fly, whereas adjusting the flow rate in the slicer requires you to re-slice and start the print again before you can see the effect.
