Thank you sent an email to the seller.

Hi guys,

My printer has a scratched bed (PEI aluminum).

I would like to switch to a magnetic bed, but I need some magnetic adhesive as an interface. Is this a viable option, and where can I find a good heat-resistant magnetic interface?
Thank you

Hi all ,
I am experimenting on probing point and G32 .
If I use 3 probing points I receive :

G30 P0 X9 Y284 H0 Z-99999
G30 P1 X301 Y269 H0 Z-99999
G30 P2 X162.5 Y19 H0 Z-99999 S3

Manual corrections required: 0.00 turn up (0.00mm) 0.02 turn up (-0.01mm) 0.03 turn up (-0.01mm)

If I use 4 probing point the result is

G30 P0 X9 Y284 H0 Z-99999
G30 P1 X301 Y284 H0 Z-99999
G30 P2 X301 Y19 H0 Z-99999
G30 P3 X9 Y19 H0 Z-99999 S3

Manual corrections required: 0.00 turn up (0.00mm) 0.73 turn up (-0.37mm) 0.49 turn up (-0.24mm)

If I do a height map using 3 or 4 probing points the result are as follows.

3 points

4 points

What should I use?
are these results coherent?

Thank you
Andrea

@mrehorstdmd Thank you for your answer.

I made another test at the same speed with a triple-layer perimeter circular pattern.
My setup is a Revo Six hot end with a Titan extruder driven by a slightly underpowered Nema motor than the one suggested by E3D for Titan.

The pulleys and belts are okay, and the hot end attachment seems rock solid. My concern lies with the mini V wheels or the wheel bearings, which could deteriorate over time. I am searching for a reliable European seller to buy good-quality V wheels.

This is the result of the print at 130 mm/s. During the print, I could hear a rhythmic noise pattern coming from the Y-axis. This is the reason I am considering a wheel problem.

@mrehorstdmd Thank you very much for your suggestions.
Can you give me some hints on were to start to backtrace where the problem with under extrusion could be?
The extruder is a Titan extruder with a lot of print on the shoulder, maybe I could try to replace it but I don't know if replace it with another Titan or something else, I am tempted by BMG even If I have to design a new hot end carriage)

Thank you
Andrea

Hi guys.
I am trying to psuh my homemade corexy 3d printer to limit.
What do you think I could improve?
I still have to configure pressure advance.

Variabile speed form 120 to 200 mm/s

@oliof Thank you for your answer.

My firmware movement speeds are

Increasing the acceleration from 1500 to 3000 I obtained this accelerometer pattern

I run the test you pointed me out but I don't know if I settled up correctly.

This is the result

Now I am stuck

Thank you

Hi guys,
I mounted an accelerometer on my c-bot
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.6 (2023-07-21)
Duet WiFi Server Version: 1.27
It seems to be working fine, I tried hand-shaking it for confirmation.
The " problem " is that it doesn't measure a real "peak" when mounted on my machine, al measurement seems coherent with each other so it seems fine
What should I do next? Where should I put the "peak" here?

Here is a video

Hi guys . I have a C-bot :

Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.6 (2023-07-21)
Duet WiFi Server Version: 1.27

Z-axis is driven with 3 screws and one single motor. My zero on z axis is done by bl.touch

When I am thinking about zeroing the z-axis after power failure I am thinking at 2 ideas.

1. I make zero on the bed using bl-touch probing on a far angle so , ideally , the already printed material isn't caught in the printer axis.
   in this case resurrect-prologue.g could be something like this

M116 ; wait for temperatures
G28 X Y ; home X and Y, hope that Z hasn't moved
G90              ; absolute positioning
G1 X20  Y20 F6000 ; go to first probe point
G30              ; home Z by probing the bed
M83 ; relative extrusion
G1 E5 F3600 ; undo the retraction that was done in the M911 power fail script

Do you think it will work?

2. make zero on the other side of the z axis using a mechanical or optical endstop at the and of lead screw . The 3 screws are moved together so no need to level the bed. In this case I should use this zero sensor only for power failure.
   In this case where I should hang up the sensor ?
   Can you give me some suggestions?

Thank you

@infiniteloop I am in the process of reducing all possible bending sources in my print, and then I came across this article. So I decided to get rid of this variable

https://www.cnckitchen.com/blog/bang-bang-or-pid-bed-temperature-control#:~:text=If the parameter B is,while%2C it's bang-bang.

Thank you for your suggestion .

Hi guys.
I have a 220 v heated bed. Safety features are grounded lines, temp fuse, home assistant monitoring temperature and cut line if needed.
I am using bang bang regulation but I would like to switch to pid because teh 1 C° fluctuations make some banding on the print.
Can I safely use pid regulation on an SSR MOSFET
Mine is a crydom d2425

Thank you

Hi guys,
I would like to try Orca slicer but I am having a problem with it.
If I start the gcode the bed is heated but the print starts with the extruder at ambient temperature.

Any idea if this is a problem with my setup or a slicer bug?

Thank you

@infiniteloop thank you for your answer.
I found only now time to answer you.
I disassembled the sensor and I found that the wheel in contact with the filament was deteriorated. Changing it to a new one seems to fix my problem. Regarding the piece of PTFE tube below the sensor, I am having problems using this because it makes the filament load in the titan quite hard. Anyway, I'll try to add it.
Thank you
Andrea

Hi guys, lately my printer has started to print badly.
I tried to print the same part with the same setting with 2 different filaments. All the print has the same defect in the perfect same place, can you help me identify the problem?
Thank you
Andrea

Hi all ,
lately, my filament monitor keeps giving me an error (filament error on extruder 0: tooLittleMovement), as soon as the print is started.
I am not having errors in led blinking on the switch on .
If I run M591 D0 , after disabling the filament monitor so the print work can start, I receive very high measured sensitivity at first then it starts lowering during the print.
Also, as you can see in the first line of the console output, the print was stopped just after I received a normal calibration measurement

Here a video of my sensor during error https://youtu.be/sEMcTP_MTII

Any idea? The behavior seems so erratic to me

Happy new year , Andrea

Thank you all for helping me.
I solved opening the case of the magnetic sensor and cleaning it. A lot of debris of plastic was around the ball bearings.
I made 2 hours of printing without issue.
Thank you

@lo-fi Thank you all for your help.
I printed your mod and another original one using a SLA printer I'll remove the sensor and I'll check it.
I never had an issue in not using the PTFE tube because the sensor is mechanically fixed to the extruder, anyway I'll can add it .
thank you

Hi guys,
I am having a lot of random false alarm with my filament sensor. It worked like a charm in the past.
The typical behavior is that the min % gradually, very fast, goes to 0% and stays there forever event the filament extrusion remains regular.
The error appears in almost every kind of print and print materials
During printing the led of the filament sensor is almost green but in specific head movment it become first off and then red.
Here a video that show it

@claustro Any help?
