Never mind. I just found that polarity in the control wires is irrelevant.
Heater works now.

I new it would be simple but was not seeing it. even after looking at my other 3d printer. Thanks so much. working fine now

Hello guys again,

i just came back after some further testing of this leveling feature. I thought maybe BLtouch was giving wrong signals. I have replaced probe with E3D smart IR probe. I was able to mount it much closer to nozzle and probe whole bed a little better (offsets 6.2 mm x 17 mm). Also I have anti-backlash nut on Z axis.

I was still using the function to probe every single points at least 2 times and with accuracy of 0.01 mm. Smart IR probes much more reliably and gives better repeatability. Also I have been using glass fiber bed (since glass one had strong bowl effect). Bed mesh looks very close to how the actual bed looks like. Attaching bed mesh screenshot.

Bed mesh appears to be working much better than it was before, however. Z probe calibrated at Z=0 (touching bed). Tried print object over whole bed and nozzle is way too high everywhere. Lines are not being connected, but it looks like bed mesh is working completely fine and compensating everywhere. Lines were everywhere looking the same width. Just why nozzle was still too high? What I have noticed, that second layer goes perfect. But anyway first layer does not adhere with bed good enough to hold through the print and I still get not nice surface finish.

Most heaters do fine with slower control loops and zero-crossing switching; lighting and motor control will benefit from phase angle control however.

@CookieHunter said in BLTouch create weird bumps in mesh:

G31 X-21 Y-54 Z1.023 P25

I’d say it was because of the large Y offset of the probe and small rocking of the X carriage is being amplified by the offset. Try to mount the probe closer to the nozzle, preferably in line in X, so the Y offset is 0.

Interesting, old universal board uses "modern" TLC27L4 while new version 2.0 Orion uses deprecated LM324

@Phaedrux I tried it one more time and it works, sort of. Using a z offset of -1.70 it stops quite a ways from the head. I will have to re-calibrate.

@Dodika3997 You've got a bit of a learning curve ahead of you: https://duet3d.dozuki.com/c/Getting_Started

I also did the same, documented the process: https://forum.duet3d.com/topic/14485/rrf3-bltouch-setup?_=1583394715553
I'm now using a duex5 though so no longer use that setup.

So it was odd, last night I used a new profile in Simplify3D I didn't have my trigger gcode setup with yet. Set it up and did nothing else, and it began working. But the gcode in the other profiles are the same? Will have to investigate further but for now I know what I have at least works now 🙂

I finally have managed to get it run with M260.

As the parameters for writing to the data registers aren’t obvious I post my code her for one who is also struggling with that.
As well it was necessary to calculate the decimal values for some register data.

The code enables PWM for both banks and writes values for the pins 0-3.
Sx150 9 and LEDs are wired in sink current mode.
Test pins 0-3 sx1509.g

Yup, you are correct, if it blinks then the command works.
Still got some gremlins here .....

Ok, I got it figured out. While the macros for the bltouch all worked, the 'retractprobe.g' had an error in it so it was behaving strangely

Thanks!

it is working now 😄 it was the I1 that was the last thing, tnx for all the help 😄

@sniper23 said in Mid-air Printing with BLtouch and Delta Printer:

I already did G1 X0 Y0 Z0, the same position happens when bl touch starts probing.

The phrase "the same position happens when bl touch starts probing." should not be a factual statement. Z0 is not the start position for bltouch probing.

So let's verify: Enter a "G1 X0Y0Z0" manually.

When that move finishes, is the nozzle just touching the bed?

@fcwilt said in Precision Piezo Orion, Problems with meshcompensation.:

M587

thanks a lot.

removed the M587 from config.g, thanks for pointing this out.

@fcwilt Nah, likely its me - I've been known to be defective before ;o). I have 2 Orions and 2 of the previous PCB's and have never been able to get the consistency i have with the BLTouch

Just a heads up for those following this thread looking for help with their Precision Piezo Orion, increasing the speed of z travel to f850 might not work well. For example, with mine, if se tthis high the lights go out on my probe and the head flexes bad against the bed before any light comes back on (on my orion). At f450 and lower I seem to get reliable probe activations.
I am unsure why this happens though for I have changed the wires and it still happens. It seems like the probe loses power or shorts, suggesting a lose wire or contact point on the board.

Thanks I just added it, (But I've only tested the idle state this evening)
I'll try and add a second printer next week.

@fus3d, which particular 2.04RC version are you running? There was a known issue in this area in 2.04RC3 which was fixed in 2.04RC4.

That's the version I'm running will upgrade today and report back.

Well that was easier than the first time I updated the firmware. RC4 fixed it. Wish I had checked back sooner, that was a painful diagnostic.

Thanks!
