BLTouch working

garyd9

I've also heard that bltouch may be sensitive to the currents generated by the bed heater. So using the M558 B1 parameter supported in firmware 1.21RC4 may help.

I'm actually starting to believe this. When using multi-tap with B1 A3 (and leaving S at the default 0.03), my printer probes exactly two times at each point. Without B1, I'd often get a third tap (and sometimes even a warning in the console log about inconsistent measurements.)

Of course, now that I've posted this, I'm sure my BLTouch will start becoming wildly inconsistent regardless of B1 settings or not.

@nickpgre:

I had to lower my probing speeds and also introduced a recovery time. Still the probing heights changes range between -0.03 to 0.03 but my prints especially the first layer never caused me any issues.

From M558 P5 X0 Y0 Z1 H5 F500 T2000
I have M558 P9 X0 Y0 Z1 H5 F160 R0.250 T2000 ; P9 probe

Not sure if this was intended for me or not

I figured I could post here my question regarding the bltouch smart setup on my duet WiFi.

I am not using the duex, I followed instruction from the betrue blog, compared them with the ones here and can’t seem to get it working. I’ve cut the little logic strip to make it 3.3v. It’s setup on my #7 heater.
When I fire up my board the bltouch does its double pin down/up but after that I can’t get the probe to deploy or move using the M280 P7 S10 I1. The red light on the BlTouch is constantly on (can’t seem to find what that means on their instructions).

Any ideas/suggestions?

Post your config.g and config-override.g please.

Well i've switched it to heater 3 and it seems to be working fine. Perhaps is there a bug? The only thing i've changed is the P7 to P3 in my retract and deploy.

I'm guessing you unbound heater pin 3, but were originally using heater pin 7. Glad it's working.
