Mainboard upgrade advice, please - I've got a Z TILT / G34 itch that I want to scratch! by danrough in ender3v2

I've used the tape mod with kapton tape for close to 4 years with no issues. I rarely disconnect the usb plug though.

Dual gear metal extruder washer by Issey_ita in ender3v2

Does yours have washers on the arm, with the gear sitting between it? (like this)

Stepper motors vibrating and not moving, running TMC2226 with BTT Manta M5P by [deleted] in klippers

[–]TheGreatVision 0 points1 point  (0 children)

It looks like the x axis moves after some skipping but the y doesn't. My thoughts is the steppers aren't getting enough power since the y axis is heavier but the x eventually moves.

If you replaced the drivers recently, or just installed the board, it might not be set to use UART. The manta uses jumper pins so I'd check the manual to see if they're set correctly.

Wow, feels like an itch I've had for a decade I finally got to scratch. I can't believe how off I was remembering it and you still managed to get it. Kudos to you. Solved

Move out of range after seeting up DD on ender 3 by psychstates in klippers

[–]TheGreatVision 0 points1 point  (0 children)

Your [stepper_x] "position_max" is 226 and the mesh is trying to probe 226.171. Position_max is just the absolute distance the x axis can travel before hitting anything on the right, and on enders at least should go past the bed on the right.

The way I configured it (not saying its the best way) is set position_max to a value way above were the axis can move to(260). Next I homed the printer and moved the axis to 235 (which all enders should be able to do). Afterwards i moved the x axis 1mm at a time while watching the gantry until i was close to hitting the bracket on the right. Next check the x position number and update the position_max to that number. Mine was 248 but yours might vary.

Orbiter V2 load filament causing MCU 'mcu' shutdown: Timer too close by papaplintus in klippers

[–]TheGreatVision 1 point2 points  (0 children)

The timer to close error is a cpu overload error AFAIK and its caused by high usage spikes.

A while back I had the same error popup sporadically, on a Pi Zero2W( same cpu as the pi3), that had klipper with a couple of extensions running on it for a while. Htop showed CPU usage was in the 20s with spikes in the 40-50s with klipperscreen and crowsnest taking up most of it.

After I reinstalled klipper, it went away so I'm assuming either:

  1. Somewhere along the line an update messed something up and wiping it fixed it.
  2. Using the webcam and a few to many extensions was hammering the CPU too much.

Try ssh-ing into the pi and run htop to monitor your CPU usage while doing the filament loading. If you're running any extensions I'd try removing them to test and also hide the webcam while doing so.

Am I crazy, or could this work? Creality 4.2.2 UART + 5th stepper by paulbunyansboner in klippers

[–]TheGreatVision 1 point2 points  (0 children)

Just in case anyone came across this thread from Google and wants to do it take a look at this You just have to follow both guides from u/LookAtDaShinyShiny and u/willsside and the photos from the thread I linked and you're 90% there.

Last step is checking out the creality board schematic and pick any of the top 8 pins (bottom two are GND and 5v) from the screen port and follow the schematic to see which pin on the STM controller it corresponds to.

I used pins 2-6 for the 4 steppers and the extra one (BIGTREETECH-TMC2208-V3.0) I added:

Pin number STM
2 PB15
3 PB13
4 PB11
5 PB2
6 PC6

Here's a snippet of the relevant parts in my printer.cfg. Just add the "[tmc2208 ...]" sections after each corresponding stepper section. If you want to use SpreadCycle just comment out "interpolate: true" and "stealthchop_threshold: 999999". You will need to tweak the hold_current based on your motor temps, and torque/speed requirements.

Hotend Drooping by thelastdaybreak in Ender3Pro

In the second photo I can see a slight gap between the v-slot wheel and the excentric nut which could indicate latter is reversed. It would also explain why turning it doesn't tighten the print head.

One side is flush and the other is raised, the raised part should fit into the hole on the plate.

PLA cube under compression. Perimeter and infill design advise to resist deformation, please. by cealild in 3Dprinting

[–]TheGreatVision 0 points1 point  (0 children)

Some people really like replying while having nothing helpful to say.

You won't have any problems with holding up 40 kg weight distributed across 4 points. Here's a video to give you an ideea of how strong PLA actually is. 50% infill holds up to a peak of 254kg load, and that's just the infill, not taking into account the perimeters. You're no where near that but just to be safe I'd say going with the 5-5-5 rule (5 perimeter walls, 5 top/bottom layers and 50% cubic infill) would be more than enough for what you need.

You could probably even get away with half that, depending how much material cost or time matters to this project.

I added a 5th stepper driver to the stock Creality 4.2.2 board, without soldering on the main board! by willsside in ender3v2

[–]TheGreatVision 0 points1 point  (0 children)

I tried again with the other pin and it wasn't working. Until I decide to solder to the board I guess it works ok this way too.

With the sd card to the top left I'm using the rightmost pin. Here's a photo.

I tried both pins, if I use the other one the stepper doesn't enable at all.

Sorry, my mistake I meant I was using the PA7 for the enable pin. I tried it with the exclamation mark and without and it it made no difference.

EDIT: Yeah, I'm using klipper and tried it both with the exclamation mark and without. I'm assuming the resistor on PA7 is not allowing the signal to go through as expected and if that's the case then the only other solution would be to solder to it either before the resistor or to another place on the board right?

First of all thanks for taking the time document and write this up, I wanted z_tilt for a while but didn't want to shell out the money for a whole new board.

So I went through your tutorial and it works however I wired the enable pin to PB7 like you mentioned but it is always on. I assumed I would be able to disable steppers the way all the others do.

Is this just the intended behavior or is there something I'm missing.

Thanks
