RatOS Alpha bug?

Running the latest RatOS Alpha. V-Core 3.1 500. EBB36 toolboard with Super Pinda Everything works great. No issues with homing, z tilt or running a PAM mesh for prints, but when I try to do a full bed mesh run the probe goes to the front left and off the build plate, causing the nozzle to crash into the bed. Works fine in stable release. (Also out of curiosity, why has the prime blob been moved to the right side of the bed VS left?) Thanks!

Are you using sensorless homing? The prime blob was moved because of stowable probes.

I am not using sensorless homing

Please post your printer.cfg.

You're missing #[include config/printers/v-core-3/physical-endstop-x.cfg] on line 97 But that wouldn't fix your problem. Have you tried disabling PAM? As in, don't include it, don't include the parameters in START_PRINT either

I'm asking since the bed_mesh hasn't changed for a year: https://github.com/Rat-OS/RatOS-configuration/blame/v2.x/printers/v-core-3/500.cfg#L16

So it's some of your extras

blacksmithforlife•2y ago

Is your probe offset right? https://github.com/Rat-OS/RatOS-configuration/blob/v2.x/z-probe/probe.cfg#L7

You also have skew correction but nothing defined under it

miklschmidt•2y ago

the skew correction settings are in the klipper config section

blacksmithforlife•2y ago

Ok, well disregard that then

NightLink42•2y ago

I have an toolboard connected, so it's on line 259/260. Do I need both? I'll disable addons one by one and see if it makes any difference and report back It's a stock EVA setup but I'll doublecheck all the measurements just to be safe

miklschmidt•2y ago

Yes, but it'll work without it, but it would be good practice using both, the toolboard part only overrides the pin.

NightLink42•2y ago

Checked the offset and it's close enough (off by about a MM to the middle of the probe), and uncommented X end just because and no change. I'll install a fresh copy and see what happens

NightLink42•2y ago

Update: full fresh install with any addons commented out and it’s still giving the same issue. Saw a comment on the video asking what I was pressing. It’s configuration, bed mesh, add profile, and save. Same thing happens when using the web ui to make a full bed mesh (heightmap, calibrate, calibrate) Here’s another video https://youtu.be/sVuSMCaaWhA

blacksmithforlife•2y ago

Huh? Why are you adding a bed mesh, that is done as part of the start print macro isn't it?

NightLink42•2y ago

To check to see how flat the bed is and if the frame needs adjusted at all

blacksmithforlife•2y ago

I am not used to that front screen, but in mainsail you just do BED_MESH_CALIBRATE in the console

NightLink42•2y ago

Same error. The probe goes off the bed and the nozzle crashes into the bed.

4:31 PM
No trigger on probe after full movement

No trigger on probe after full movement

Wonder if it has anything to do with changing to a toolboard, as it worked fine previously and with the stable branch I'm also noticing that the Super PINDA probe only probes the bed once when doing any tilt correction/meshing vs collecting multiple samples when connected directly to the board on stable branch. Only on leveling Z it does it twice (as shown in the video)

blacksmithforlife•2y ago

Mikel can correct me if I am wrong but I don't think it has anything to do with the tool board stuff. He did rewrite a bunch of the macros so maybe something in there. It seems like it isn't applying the correct offset for the probe or has the wrong points defined or something If you home just X and then manually move your hotend all the way to X max, what is the number you get? I am trying to see if maybe the endstop is in the wrong place and so X=0 is in reality a negative number for you

NightLink42•2y ago

One moment It maxes at 500 but it looks as there’s still a bit of room

After moving all the way to the right, 0 on X looks correct

I also see no visual difference in regards of “nozzle to bed” location between having the nozzle at X0 Y0 and X0 Y500, just to rule out an insanely skewed frame lol. (Hope that makes sense). Also, just for the hell of it, here’s a video of Z home vs tilt https://youtu.be/7j2c8QB7cHA

What happens if you add this to your config?

[bed_mesh]
mesh_min: 60,60
mesh_max:445,440

[bed_mesh]
mesh_min: 60,60
mesh_max:445,440

miklschmidt•2y ago

Can you show me where the nozzle is on the bed when you go to 0,0?

Hmm, this fixed it. Mesh ran fine with this added to the config file.

blacksmithforlife•2y ago

Well that is good in that it is actually obeying the config. But curious that other people aren't having problems. @miklschmidt I noticed the min is 20,20 - but the X offset for Eva 3 is like 28mm. So maybe the default should be like 40,20?

NightLink42•2y ago

It may that be the active installs of alpha and those who are trying to run a full bed mesh is pretty low. I'd guess people who are running it already have a pretty well tuned machine, so a full bed mesh wouldn't necessarily be needed. Only reason I was running it was to make sure the changes I made to the frame earlier this week didn't throw everything out of whack.....and looking at my mesh it badly did lol

miklschmidt•2y ago

bed_mesh takes probe offset into account.

I'd guess people who are running it already have a pretty well tuned machine, so a full bed mesh wouldn't necessarily be needed.

Not the case here. I always test the vanilla release and i can't reproduce it. Also find it strange because it hasn't changed. Can't see the nozzle here, can you take pics from the front and sides? omg.. I know what your problem is now.

# Inductive/Capacitive probe
#[include config/z-probe/probe.cfg]

# Inductive/Capacitive probe
#[include config/z-probe/probe.cfg]

You never uncommented a z-probe. So you have no offset. Uncomment that and your problem is solved 🙂 line 87

NightLink42•2y ago

Ah shit that did it! Wow. lol I guess I skipped past it when I was setting up the tool board. I am so sorry for wasting everyone’s time >.<

miklschmidt•2y ago

No worries, support is what we're here for! I missed it too 😂

blacksmithforlife•2y ago

Yeah I missed it too. I really need to get a app for my phone that does syntax highlighting

NightLink42•2y ago

Thank you both. I massively appreciate it

blacksmithforlife•2y ago

Thanks for bearing with us as we made you troubleshoot everything

NightLink42•2y ago

No no not at all! Thank you for helping so much!
