Piezo20 probe and piezo kit now available
-
Thanks for the answer, I'm following the reprap thread too, so I can post it there too if you want to.
I'm doing the test with the nozzle at 120, although I think I will need to increase it, for PETG I think is too low. I will look for the 2 readings stuff, and play a bit more with the sensibility, I'm not worried about that, I've reduced the false triggering almost to zero.
Cheers!

Has anyone switched from under bed FSR setup to under bed piezo?
If so was it a major improvement over the FSR setup? -
I'm a little biased but if you consider going from 50-100g of force to trigger with FSR's (I used to have them), to 10-15g with piezo, then it must be an improvement.
However when it comes to the best approach for a delta I would say fix the bed rigidly, use the hotend based piezo probe. The results speak for themselves, I get 0.007 deviation when auto-calibrating, and that's probing 64 points, to ensure it wasn't just a lucky result.

any update on when the drop ins will be available?

OK, Thanks. The under bed approach would be much easier but I have started to see some progress on Rostock Max V3 integration at the effector.

Should have some PCB's this week and then I can list some on the site. I will post here but the main channel for announcing new stock is the thread on reprap under general.

Finally got time to install the piezo probe on my selfmade I3 clone.
I must say I am impressed, it works really well.
Have on issue though, when I run mesh bed leveling the heightmap is like this:
someone has an idea what could be wrong?
these are my current parameters in config.g (running on 1.19b10):
M558 P5 I0 X0 Y0 Z1 H2 F150 T1500 R0.8 ;digital piezo sensor, output rises on contact, probing speed, used to home Z axis
G31 X0 Y0 Z-0.14 P150 ;sensor is nozzle and debounce value.

That's weird, where did you get that info from?
It was showing a correct map when I was using the inductive probe? -
Go to bed centre and issue G30 (no parameters) this resets Z level, then do G29.
Also make sure you erase/change the G31 z offset in config_override.g as it overrides the value you set in config.g - this has got me multiple times!

this is basically what I am doing, I home Z before doing G29 (and I have no config_override.g).
My homez.g file:
G91
G1 Z5 F100
G90
G1 X100 Y150 F9000
G30small resume: probing/mesh bed leveling works and my heightmap looks ok when I look at the numbers, but the graphic is not ok in DWC.

Thanks, missed that bit

Thanks DJ! I ordered it right away.

Thanks for the order, I'll get on with making it.

Chrishamm released 1.17+2 that fixes this problem…

…but you need RRF 1.19beta10**+2** to work with it, if you haven't already installed it.
