I am having this issue on my IDEX printer where the u-axis for the second extruder is significantly louder compared to the x-axis. There seemed to be more vibrations when moving causing the extruder to resonance with it
I tried a couple of things but it doesn't seem to improve the situation:

• switching the driver of U axis
• switching the stepper motor
• enabling/disabling interpolation
• change to 256 microstep

Here is my config.g, I made sure the configuration for both x and u axis are the same (except for 256 microstep on u axis currently):

@o_lampe Do you know if there is an example code I can look up to adjust the leadscrew? It would be really nice to store the offset, do some math, and then print it out as a prompt on the LCD display.
I think if I wire all endstops with series and connect them to active high, then once one is triggered, the entire circuit will switch to low. I can then use only one io port on duet.

@t3p3tony So I think the correct way to frame this question is if I can use G30 to probe 4 points, record the "G32 bed probe heights" and save it to heightmap.csv using gcodes defined in the firmware?

@t3p3tony Your point is right, what I thought about this is that I will first level the bed manually, then probe the four microswitches, record the offset at each probing point, and update the offset of each. I just wonder if currently, RepRap firmware allows individual offset and mixed tools for probing. Sorry, it is quite a wired use case.

@t3p3tony https://youtu.be/EDbU1zlC3Ss?t=148
So instead of mounting microswitches on the hotend, which is pretty crammed for an idex setup. I want to try to mount the microswitches on the bed instead.

I previously saw someone/company using endstop mounted on the carriage to probe the bed with 4 points (I will add the link to video if I can find it). Two on the left using left extruder, two on the right using right extruder. I would like to try mounting 4 limit switches on the bed wiring them in series such that I can use the left extruder to touch the left two and vise versa. This means that there will be some z offset for each of the limit switches and I need to probe the mesh with two extruders. I searched around and couldn't find any resources on that. I'm thinking of something like this:

G30 P0 X20 Y50 Z-99999 H3.5 
G30 P1 X20 Y200 Z-99999 H3.1
T1
G30 P2 X210 Y200 Z-99999 H3.2
G30 P3 X210 Y50 Z-99999 H3.1 S4

But G30 with S parameter seemed only to be for printers with multiple z motors.

Thanks!

@theruttmeister Learned a lot. Thank you so much for this comprehensive answer!

Currently, processes from desktop metal and markforge require buying a sintering oven to do that. Able to directly print metal on an FDM printer will definitely be awesome and game-changing. Slice engineering's copperhead hotend can go up to 450 C and some welding filaments for aluminum melts at 600 - 650 C. I wonder in theory if there is a hotend that can reach that temperature, will it be possible to directly melt and print metal welding filaments that way? I guess the finished part doesn't need to compete with machining and casting strength but still could be way better than most plastics.

Hi all. I am trying to implement something resembling the Ultimaker filament switching routine on RRF3. Ultimaker allows the machine to extrude material until the user clicks a button to stop the extrusion. I wonder if it is possible to achieve this with either a while loop + M291 or use an M291 command to terminate a, for example, G1 E99999 command?

I have a z_max endstop that is using a switch and a z_min endstop with a probe. Normally, I would use the z_max endstop for homing the printer. I am wondering if I first use the z_max endstop and home the printer, and then use G30 with the probe, what is the current z_axis referencing with? Is it the probe or the previous z_max endstop?

Hi, I later found out that it was in my config.g file while I configured the end-stop setting wrong. The U axis endstop is set to minimum where in reality it should be homing to the maximum. Thanks for the follow-up.

Recently for some reason, my DWC looks like this after loading. After a couple of refresh or restart, the proper GUI can show up. I am using Chrome and a Duet3 running standalone mode with wired internet.

I would like to install some LEDs on my printer. The LED has positive and negative traces pretty close to each other. I am wondering if a short to ground happening on the power supply side would damage the controller board?

Thanks for the info! I also asked a reseller of these probes and they say this type doesn't work on transparent objects. So I guess there isn't one probe that can tick all the boxes.

I was looking for probes for ABL and found out Panasonic has a laser probe lineup. It seemed like it can probe on any surface and also have exact distance output. In theory, it can be set up like Markforged and also check the part. It would be really cool if it can directly scan the bed instead of probing individual points.
I am wondering if anybody had tried it before or works in the industry and have some experience with these laser probes. They are expensive ($300+ on Digikey and $200+ on Alibaba) but if it can reliably probe the bed and part I think it is worth it.

I am wondering what is the LED between Reset and SD slot indicate. It seemed like the wiring diagram did not show what is it for.

Thank you, it seems like I put 2 S parameters in M106 which caused the issue.

Hello, I ran into this weird issue that only the heater 0 is detected on DWC.

I am sure this should be a quick fix but I could not figure out how.
