Great:

the BLV solution works like a charm. Using the UART available on the IO.1 all 4 connections rx/tx/gnd/5v and the latest github sketch for an arduino micro or pro mini...

@dakingofhearts2003 said in BL TOUCH ONLY DEPLOYS WHEN I USE THE DEPLOY/RETRACT MACROS...:

@phaedrux You can close this one out but i have another question about how to level the bed manually. I cant use g32 if i dont have multiple z motors can i ?

You can use this to make a manual adjustment assistant if you don't have independent motors and drivers.

@hey_allen if they are 24V common positive then you should be able to drive them from spare heater or fan outputs. I suggest you create code in daemon.g that monitors state.status in the object model every few seconds and sets the lights accordingly.

@oliof
When you move a motor by hand you feel the rotor switch between certain positions. Same, but not so strong with hybrid steppers we use now.
Some BLDC motors use 'halbach arrays" for magnet orientation to deal with cogging, but there are easier ways as mentioned above.

@pcr Well now I feel a little better for not being able to figure this out. Thanks for the resources, I completely missed this thread!

If you didn't want to do a permanent change to the board you could use a small external wifi to ethernet bridge device like this: https://www.tp-link.com/us/home-networking/wifi-router/tl-wr802n/v1/

Ok, will do.

If you send G92 Z10 to force it into a homed position so you can jog the axis, does it move the correct direction? -z moving the print head and bed closer? +z moving them farther away.

If it's moving in the wrong direction you'll have to change the direction of rotation in the M569 command for the z driver.

That could explain why a G30 would move it in the wrong direction.

This method is pretty cool @mrehorstdmd. I also used it like that for a long time, but I'm building a voron and I wanted to leave a small camera inside the machine, more for aesthetic reasons. I used a cell phone for a long time and then switched to a xiaomi ip camera, to look at 2 printers when I was away from home. Thanks for your response!

@cncmodeller It would be easy to modify a bluetooth button with a reed switch in parallel with or in place of the pushbutton and then place a small magnet on the edge of the printer's bed. Every time the bed rotates with the magnet near the switch it will trigger a photo. I don't know how precise it would be, but with a little more effort you could use an opto interruptor instead of a reed switch. They can be very precise, so your resulting video would be very stable.

Which pins would you like to use? One of the heater pins on the expansion port would be a good choice.

What kind of signal does your LED mosfet require?

How you configure it would depend on which firmware version you are using. In RRF3 it's as easy as defining the desired pin with a M950 command as a fan, and then using a M106 command to control that fan output.

@t0bias, if the board is detected then the I2C pins are connected correctly and the slave address is set correctly.

How are you testing the outputs of the SX1509B? I have connected each output through a 100 ohm resistor to one of the cathodes of a 2-digit common anode 7-segment display, with the anodes connected to +3.3V.

@Phaedrux Thanks, I will amend my config.g, not that it seems to have any impact on operation.

@fcwilt That is good to know. I will grab a meter and check that voltage level of that switch.

Here is actually using 3 sensors, in 45degrees steps. The auto compensation software may also need to know the filament length between each of the three sensors and the extruder and merge length shifted values to construct an estimation of the cross cut.

Considering the common tolerances of modern filament, I wonder if this complexity will result in a significant part improvement.

A simple way to test is to print 3 models with -2%, 0% and +2% from your current setting and see if the differences are significant.

Edit: regarding how useful it is, his magnetic strength based design is clever and cool.

@b3njam1n Hey! just use the code snipet and paste your gcode inside it.
