Chonk needs coding for 3 axis Z-tilt

[magic rock]

Hello guys I was hoping the Chonk builds could receive the option for z-tilt bed leveling. With a toolboard the skrat has the open slot.
ZMA= Z0 E0M= Z1 E1M=Z2 just like a V-core. This would be nice to have. Is this possible?

Chonk needs coding for 3 axis Z-tilt

[magic rock]

https://github.com/Rat-OS/RatOS-configuration/blob/v2.1.x/boards/btt-skrat-10/config-3z.cfg

[fiery venture]

Did you pick skrat in the configurator?

[fast rain]

yes

However there's currently no available 3z chonk printer config.

Wouldn't take long to make one though

[magic rock]

Please please please you would make this printer better!!!!!! I can run tests for you as I have one ready

[magic rock]

I have the normal build at the moment. I run a toolboard and have the extra slot open. Its like a mini me to my V-core 3.1 500.

I have an ebb42 on it currently but I just ordered the Orbiter Orbitool. We are mounting the toolboards on the motor and retaining the stock clearance now with the open port which would mimic a V-core and add to the build.

[deep flax]

A few minutes of work.
It will be enough to add a few lines to printer.cfg.
I haven't tried, I don't have such a board, nor 3 motors on Z.

[fast rain]

hold my beer

@magic rock done and pushed 🙂

I've just limited the Y to 170, as i wasn't sure if 180 would cause toolboard damage, IIRC it doesn't quite fit.

[magic rock]

Awesome!!! No need to limit to 170 as we have full travel

[fast rain]

With a toolboard? are you sure?

[magic rock]

plenty of room

[magic rock]

So I just need to move the ZMB stepper motor to the E1M slot reconfigure right?

[fast rain]

guess it was fixed, i'll put 180 back in

[fast rain]

yep

(you need to select the V-Chonk 3Z printer)

Update is on the way

give it 10 minutes and it should be ready 🙂 (you need to update both RatOS and RatOS-configurator)

[magic rock]

I am not using the earlier ebb mount that people were having clearance issues with. I did spread the word in the Chonk section to mount the sensor on the motor. I have an ebb36 and ebb42 mount I will upload

currently I am installing the orbitool toolboard so give me an hour or two on that.

[fast rain]

The height on that thing and the 2 point mounting looks like a resonance nightmare.. Chonk toolhead really isn't made for toolboards, lol. I think i'd rather slap a 6 driver board in the bottom but in any case, it should work. It's gonna be a problem for people who use the other mount... Now i want to limit it to 170 again.

[magic rock]

its pretty compact compared to the ebb42

[magic rock]

I have reflashed the SD card twice to reconfigure and keep getting this error code. It also keeps telling me my pi is on an older version and when I click flash board it just keeps cycling back to this message

It finally let me update everything and I did the config for the beta z but now get this error. I haven't shut it off without properly hitting shut down in klipper just so you know.

[fast rain]

You're missing strain relief. Which is what makes it so damn tall.

[fast rain]

This is an old version

[fast rain]

Are you sure you updated everything?

[fast rain]

I have reflashed the SD card twice to reconfigure
You need to update everything after connecting to wifi before proceeding with configuration

[fast rain]

This was alread fixed..

hmm

[magic rock]

what should I do?

[fast rain]

taking a look at the debug zip now

@magic rock try :

[heater_fan toolhead_cooling_fan]
hardware_pwm: True

I think the problem is because of the max_power: 0.995 and software pwm. In shutdown mode no software is running and it defaults to 1 on heater_fans (for good reason) which gets limited to 0.995, which then triggers the error.

I have pushed that fix now so you can just update instead 🙂

[magic rock]

I updated and got the same error. I then went and cleared out my SD card. Flashed the image again. Set up wifi. Did all the updates. Then I ran the configurator. Same error.

[magic rock]

This error started when I installed the orbitool. When I had the normal config and the ebb42 this error never came up.

[fast rain]

There’s no reason for all the reflashing.

[fast rain]

It’s caused by all the max_power: 0.995 requirements on the orbitool O2. You prolly need hardware_pwm for more than the toolhead cooling fan i gyess

[magic rock]

Is that something you select in the settings?

[fast rain]

No you write that in printer.cfg in the user overrides like i showed above #1298757434801786890 message

[magic rock]

Oh I thought that was part of what you pushed through in the update yesterday

[magic rock]

I dont know if I did this part right as the error is still there.

Instead of .995 can't we just put 1 like the error is asking for?

[fast rain]

Only for the heater fan, not the rest of them

[fast rain]

This is indeed already in the config. [fan] and [extruder] isn't.

[fast rain]

If you put 1.0 in max_power it causes issues with the protection features on the orbiter o2 (that's the reason it's there, it's from the original config).

[magic rock]

so what should I do here I am confused?

[fast rain]

[fan]
hardware_pwm: True
[extruder]
hardware_pwm: True

I'm assuming [fan] is enough.

[fast rain]

remove the extruder part, like i said, pretty sure [fan] is enough

[magic rock]

ok I removed the extruder part and now this is the error

[fast rain]

reflash your toolboard it's (very) out of date

[magic rock]

Ive reflashed it a bunch

[magic rock]

it just cycles back

[fast rain]

You need to flash it with manual dfu

The orbitool o2 doesn't have a bootloader

So @magic rock there's no way around setting shutdown_value: 0.0 on the heater_fan unfortunately, which is not great in case of thermal runaway or shutdown with a heated hotend.

Remove your overrides and update and it should stop complaining about PWM_MAX.

[magic rock]

I updated with dfu and it worked for the flashing. I removed the overrides and updated ratos and the configurator updates I see too. A new error now

[fast rain]

jesus christ, i'm on a roll today 😂 sorry! gimme a sec!

[fast rain]

Fixed, update again 🙂

[magic rock]

Do I need to reflash the toolhead too? The other error is back

[magic rock]

I clicked update for both ratos and the configurator then the error changed back to the old one as you see

[fast rain]

Yes you need to flash your toolboard, it's old af. Needs to be done via manual DFU as i wrote earlier: #1298757434801786890 message

unless you laredy did that

[fast rain]

Not sure where this is coming from

[fast rain]

try adding

[fan]
shutdown_speed: 0.0

back into printer.cfg

[magic rock]

That worked!!!!!

[magic rock]

homing fails though

My pinda is triggered full time at the moment and the nozzle ran right into the bed

[magic rock]

We are getting close though!!!

[fast rain]

? .. It won't move if it's constantly triggered. Please be careful when you're wiring and testing things for the first time, always be ready to hit the emergency stop.

How did you wire it?

there's no wiring diagram

Your probe's signal pin should go here

5V (brown) goes to pin 2 on that header, Gnd (Blue) goes to pin 4.

[magic rock]

I have brown on two, blue on one, black on 5

Black was Servo on the Ebb so I matched

so move one to four but should I leave black at five?

[magic rock]

I got it working. Brown to two, black to three, and blue to four

[fast rain]

yeah servo is the pin that's used to move the bltouch pin up and down, so that's why it didn't work for you.
