New 3D Printer User Seeking Help

[Rhoobarb2005]

Hi all.

Hoping someone can help a 'new to 3D printing' user out.

We've been looking at getting a 3d printer for a while. We know Creality are fairly common and we wanted the biggest print size we could reasonably afford.

So we found a used CR10 5S, where the advert stated: "Now running Klipper"

After a quick Google of what Klipper was, we thought "fair enough" and bought it. Brought it home to find that most of the cables were unplugged or disconnected, but I assumed it would be fairly simple to find where they go (Ha, that took many hours of my time up).

Well that was a couple of weeks ago because it seems that there is more to this upgraded machine than just Klipper. A lot more.
So it seems that I, as someone who has never even been in the same room as a 3d printer, have thrown myself unknowingly well into the deep end.

It has taken me a while to identify parts and boards and configuring them all, while having 0 knowledge only 2 weeks ago. It has been quite the challenge.

So what I think I have learned about the system over the last 2 weeks:

- Creality CR10 5S frame.
- The main board is a BTT Manta M8P v1.1
- 8x TMC2209 1.3 boards
- Controlled by a BTT CB1
- The printer itself does not have a touch display, monitor output only via HDMI
- Voron Stealthburner with a BTT SB2209 RP2040 controller
- Voron Tap
- Phaetus Dragon hotend
- 100k Ntc 3950 Thermistor
- Creality filament Endstop.

So someone has obviously spent a lot of time and money on it.

On the journey of getting this to work, I have learned a lot, but I have come to realise that when configuring there are many branching paths that you can be lead down for hours, and then finally end up in a dead end anyway and having to go back to the begining.

But I have hit a bick wall now where I don't know how to proceed. Hoping someone here can guide me.

I think I have got the printer.cfg mostly configured. The temps seem to be working. Klipper is no longer giving error messages in startup (so many errors!). The webcam display comes on, etc.

But I cannot "Home", because it says that one of the endstops is always triggered.
But when I QUERY_ENDSTOPS it says:

EndstopX TRIGGERED #Virtual Endstop
EndstopY TRIGGERED
EndstopZ TRIGGERED
Probe TRIGGERED

I seem to be going round and round in circles and am starting to pull my hair out.

I have tried adjusting the stall threshhold
I have adjusted the pin settings using for example:

endstop_pin: PC0
endstop_pin: !PC0
endstop_pin: ^PC0
endstop_pin: ^!PC0

While they do change the state, when the 1x hardware endstop is pressed to test (the LED on the switch lights up to show the change in state), the state doesnt change.

I'm sure there are more problems along the way, but this seems to be the roadblock I can't figure out.

Any help would be gratefully received.

Also as an addition, I did try to contact the owner. But the response was a waste of time, they couldn't even remember what equipment was in the printer. Their answer to me having trouble was the offer to sell me another CR10 that was modified differently to mine. From the interactions I have no doubt that there is a strong neurodivergeant issue there. No judgement, but "go back to the seller" isnt really an option at this point.

Any help anyone can provide would be fantastic.
Thanks

I find it a little strange that you bought a modified 3Dprinter but never printed but the fact that you are willing to get it working is admirable.

So triggered endstop. What happens when you manually trigger it and query the endstop? I am recalling from memorry since I don't use physical endstops. the ! will reverse the PIN so if you have endsto_pin: PC0 and its triggered, !PC0 will make it not triggered.

Like this picture, you have a open and closed circuit
Its the same for the endstop.

We're more focused on actual Voron machines here. for mystery-meat-started-as-cr10, you may find more useful help over at the klipper discourse. https://klipper.discourse.group/

still:for sensorless homing: you should definitely be seeing the endstops as "open" before you start homing. I'm curious if PC0 is actually the right pin: that's the endstop for motor4, which seems like an odd place for an x motor to be connected... I'd probably start by verifying the pin, and making sure the diag jumper for that motor is installed.

Well, I was only expecting the modifications to be that it ran Klipper. That was the whole description for the printer advert "Now runs Klipper", that was it.
I googled what IKlipper was and thought "huh, that would actually be useful". It was only after I started trying to set things up I realised what I was looking at for nearly every part except the frame and motors wasn't what would be on a stock CR10.

Like I said in my post, I think the owner had some mental health issues.

Anyway, I queried the endstop when I was manually pressing, then queried on releasing the physical endstop. It changed nothing. It was not registering the state change of the switch.

I tried the configurations of:
endstop_pin: PC0
endstop_pin: !PC0
endstop_pin: ^PC0
endstop_pin: ^!PC0

While the default state did change, it still did not register the change in state when the switch was pressed.

i.e; If the default state was open, after pressing the switch the state was still open. If the default state was triggered, after pressing the switch the state was still triggered.

I appreciate the help so far.

I'm a bit old for discord, but I will look into it, thanks.

I did download the manuals for all the boards, but I will double check the pin. I'll double check and reply with the findings, plus my printer.cfg. The clue may be in there.

Again, I appreciate the help so far.

The voron discord has up to and including retired folks on it, and is rwally the main platform for voron help. I honestly don't think it is age-limited at all. but, more importantly, the klipper *discourse* is a forum, not unlike this one.

That all aside, I think a copy of the config, and a photo of how the manta is wired would both be very useful things.

 

[NoGuru]

Agreed with shiftingtech, lets see the printer.cfg and a photo.

Also, I am a grandfather or two and I use Discord daily for many things I do.

 

[claudermilk]

Yeah, we "olds" get to use Discord too. Sometimes the Voron one can feel like trying to drink from a firehose, but it is loaded with knowledgeable, helpful people.
