@tkln It has a strain gauge built in to detect the pressure of nozzle contact.

32GB and FAT32.

@sniper23 said in Uneven Fixed Delta Printer bed with Bltouch and 3D Touch:

Well, that didn't work. did the calibration and M500, still same.

Did you leave the M501 in, to auto load the overrides?

Can you show what is in the config-override.g file?

@sniper23 fair enough. as you are then

you could:

disable power via USB by taping off the power connection in your USB cable power the board via the optional external 5V input (see https://duet3d.dozuki.com/Wiki/Hardware_Overview for the wiring diagram).

Also make sure to check the back of the board for any bad solder spots, and as others said before, triple check your wiring.

@sniper23 said in Smoke when supplying through USB?:

Hey, everyone. I was seeing all the LEDs just fine. But smoke came from USB socket, didn't happen before. Any ideas?

This generally happens when you are using VIN power but you have USB connected too, and you have both a USB ground loop (look it up on the wiki) and a poor connection between the negative PSU output terminal and the corresponding VIN terminal.

@Veti I was using 6 factors, it was the same for that. Switched to 9 factors after. My offset is 20 btw, Y offset.

@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?

@denke I have fixed the issue, for now.

I use 24V, not 12V. I use a 220W power supply.

@sniper23 said in Is possible to edit calibration (G32 and G29) results?:

@fcwilt I use manual calibration.

Got it. A couple of questions:

How are you doing the manual calibration?

How much error are you seeing in your Z positions?

Thanks.

We are planning to extend the Maestro range with a WiFi version and probably a RPi version, but we're not planning to support CAN on it.

@sniper23 said in membrane switch Sensors? Anyone using with Duet?:

It looks like something better and more reliable than Bltouch

Probably not. I’ve experimented with a FSR but replaced it with an opto-mechanical sensor, as the sensitivity varied heavily with temperatures and over time.

Sure, the membrane acts as a direct switch between nozzle and print bed, but in practice, the expected precision vanishes as soon as you have some filament on the nozzle. Even worse, you can’t pre-heat the head to avoid this - the membrane would melt.

To measure, the membrane sensor must be mounted onto the nozzle, then be removed again. This is no stable arrangement, it might easily come loose during the levelling process. With silicon socks, you can't even fix it at all. Finally, it is quite inaccurate to level a cold bed.

As with my FSR, any membrane wears out over time, optical or mechanical switches are much more reliable.

@dc42 So I can't see probe points generated by G32? Only the text?
