Can Anyone Share Their HEVO Configs?
-
Hey all!
I have a HEVO with BLTouch, E3D Hemera Direct Drive, Duet2 WiFi. It works pretty good for the most part, but there is a few minor issues.
1 - BLTouch when turning on the printer will sometimes just blink red and not deploy/retract probe. I have to manually pull the probe out and then reboot printer for it to work as normal.
2 - Stringing issues. I am thinking maybe speed/acceleration settings could be affecting this.
Would anyone that has a HEVO with somewhat similar hardware and working well be able to share their files so I can compare to mine? A lot of the firmware configuration I am not completely certain is setup properly and would be interested in comparing some of the config settings.
Also, I am thinking of figuring out a way to attach a filament runout sensor.
What is the best way to set Z Offset also, is there a way to baby step it during a print and then lock in the change or do you just have to keep track of the change and then edit the config file?
Thanks for the help,
Justin -

That sounds like a wiring problem. The BLtouch should do a self test immediately on powerup with 5v. If it's not doing that something is either not making a good connection or the probe itself is failing.

Usually comes down to printing temp, cooling, retraction, pressure advance, speed, jerk and accel will play into that as well as part of retraction and travel moves.
It's unlikely that someone will be able to provide you a config file that will work perfectly on your machine. You'll have to do some tuning.

I had exactly the same issue, that was driving me crazy....
Check the Pin
"Try loosening or tightening the set screw slightly to adjust the trigger sensitivity."The description how to set up the srew is in the manual
In the end a quarter turn had reliably solved the problem.(UTC+1)

@Phaedrux Thanks for the reply Phaedrux.
1 - The BLTouch does do the self test and 3/4ths of the time it works fine. The other 1/4th it just blinks red and I have to pull the pin out and reboot.
2- I know I won't be able to import the config directly and use it, but thought it might be beneficial to see what others are using that work. Maybe my acceleration settings are too low (I did tweak these some for the extruder and it seemed to help, but think it could be better).

@DIY-O-Sphere Thanks DIY-O-Sphere. I will check that out and read the link as well. I have never adjusted a set screw for the BLTouch so I have no clue if it needs to be adjusted or not. Like I've said it works most of the time so didn't seem like a wiring issue, but couldn't really think of what it could be. Thought maybe a faulty BLTouch or just some weird configuration setting.

Feel free to post your current config files and settings and we can provide some suggestions and feedback. photos of test prints also help.
For the BLtouch you can also remove the pin entirely after removing the set screw. Sometimes they need to be cleaned or may have a defect. If it's failing the self test occasionally that's definitely something to check.

Thanks Phaedrux. I will check the pin out as I haven't done that. I will try to post a picture later and the config files as soon as I find the best way to do that here. I don't have much photos currently, but may have something that will help.

The BLTouch self-test will fail if the pin doesn't drop fast enough or fully enough when it is released. This will happen if the nozzle is too close to the bed to prevent the pin deploying fully, or if the BLTouch is on its side (as it usually is when I am bench testing one), or the pin has become sticky and needs to be cleaned.

The HeVO isn't the most rigid printer design. You may need to reduce your acceleration and jerk settings a bit to try and eliminate the ringing you're seeing. Tightening your belts may help.
I'd also try increasing your extruder jerk to ~3000 and try tuning pressure advance.
-
@Phaedrux My frames pretty solid, but I'm not using linear rails or anything and it's direct drive instead of bowden. I really haven't even thought about the ringing much yet to be honest, but it is definitely something I will consider. I think all the belts are pretty tight and should be fine I believe. Should the jerk and acceleration just both be gradually reduced until the ringing goes away ideally?
I will try increasing the extruder jerk to 3000, it was at 120 and I upped it to 270. Wasn't really sure how far to take it. That may be quite a bit of help with the string. No clue what pressure advance is, but I will look at the link you posted.
Thanks for all the help.

I have the same setup, only difference is that I'm using my Duet 2 in SBC mode. We'll, it's not quite a duet anymore, but still close enough for the configs to be comparable.
I have a PT100 for the hotend which may not be what you have, so that may be a difference.
My accelerations and such are tuned right now for speed over quality. I'm printing lots of functional parts, so ringing is largely irrelevant, so I'd ignore that part of my config

@keyz182 Thanks, I appreciate the info and copy of your config settings. I will look them over and see if maybe there is any tweaks that could apply to mine.
Yeah, I have checked the wiring to my BLTouch and everything appears good. I am planning on checking the pin and see if there is something odd there. It's not too big of a deal as I can resolve it pretty quick, but would be nice to have it work more reliably.
