BLTouch w/ DUet 3 mini 5+ Wifi (Ender 3 Pro)
-
Very interesting. I copied their homeall.g and homez.g
I tried the g30 command but the BLTouch did not deploy. i stopped it before it crashed into the bed. I also tried to home XY but for some reason the pins are not being read. Any ideas on these issues?
-
@teachmedavis747 OK, so:
EDIT: Forgot: Do you have the deployprobe.g and the retractprobe.g in your /sys directory? How do they look ?
EDIT2: Your endstop config is correct. But how have you connected them. It should be ground and in-pin? Move the bed to the endstop and the x-carriage also to the endstop and check status with M119
- Does the BLTouch glow red when the printer is on?
- WHen you start the printer does it deploy and stove the pin twice as a startup routine?
Can you show how you have connected the probe wires ? Picture ?
There are so many different colour variations of the wiring so do you remember how you had it connected with Marlin?
-
Yes, It glows red and deploys twice once powered on.
Here is a picture of the wiring:
Edit:
Here is deployprobe.g
M280 P0 S10and retractprobe.g
M280 P0 S90Edit 2: Here is the M119 with both x and y at the endstops:
Printer is now online. >>> m119 SENDING:M119 Endstops - X: at min stop, Y: at min stop, Z: no endstop, Z probe: not stopped -
-
Nothing happens when I send either deploy or retract

OK, this should work, Can you send a picture of the BLTouch where you can see the wires as they go into the probe just to make sure that the right wires goes to the correvt places. We know that 5v and ground is correct. But we should be able to deploy with the config that your have.
You have saved and restarted after the changes right?
-
@teachmedavis747 Also, please post your complete config.g again.
Just to make sure ... -
Hi. I apologize for the delay. I was under the weather a few days. While I was down I ordered some new wires for the BLTouch. I installed them today and figured out that was my issue as far as deploying the probe. Fixed.
Question for you. When I hit "Home X"and "home y"... should the bed and X axis move towards the end stop pin? They do not make that move.
-
@teachmedavis747 That's great.
Yes, as long as you have a homex.g and a homey.g containing homing instruction in your /sys directory
-
Okay. I was able to get it to run G28. However, another issue. Maybe you can help me with this as well. I had to switch the direction of the x and y axis motors in config.g. (I replaced the x axis motor with a high torque motor from e3d).
When I enter G28 the extruder travels in the wrong direction. Instead of going towards the pin, it travels the opposite direction. How can I fix the homing files to compensate for this change? I will attach my config.g and homeall

How can I fix the homing files to compensate for this change?
There are 3 parts to this. The direction of motor rotation, the endstop position definition, and the movement direction in the homing macros.
-x should move left, +x should move right
-y should move to the front, +y should move to the backM569 is where the rotation direction is set
M574 defines where the endstops are located. high end of travel (positive move to reach) or low end of travel (negative move to reach)
The G1 H moves in the homing macros should move towards the endstop either positive or negative.
If you require more guidance we'd need to at least know where your endstops are physically located to know if your config is correct.
-
@teachmedavis747 Hmm, from the top of my head I know of no special homing or probe related changes needed to fix that. Are you sure your Z-motor doesn't need reversing as well?
When you home x and y does z move in the right direction. Up and then down again?
-
@gixxerfast Yes. Z-axis moves well.
-
@phaedrux Sure.
On the ender 3 the x-axis endstop pin is located on the far left of the x-axis. The y-axis is located at the back of the printer next to the y-axis stepper motor. I believe I have it set at low end for both when I configured the file using the RepRap tool.
So if I changed the direction in 569 for both the x and y-axis motors... what others changes would be needed to get it to g28 in the right direction?

Just do be clear can you explain what you mean here exactly?
Your homeall.g is not correct as it moves the y in the wrong direction. You should try to go to relative -(max bed size x + some more) and -(max bed size y + some more)
Also, I would split that so I first home x, then y and lastly z.
In my homeall.g I just call homex.g, homey.g and homez.g instead of repeating the commands again.

-x should move left, +x should move right
-y should move to the front, +y should move to the backCan you confirm this is the case? Note that for Y, movement of the bed is relative to the print head. So even though the bed moves forward, the print head is now at the rear of the bed, and vice versa.
-
confirmed. When i go to MOVE on my display if I hit +1 the x axis moves rights. However, you were correct. The y-axis was moving the wrong direction. Here's the format I think you were referencing.
So I changed the config.g 569 to match this and now all is moving in the correct direction.

Instead of the print head moving toward the endstop pin... it travels to the right.. away from the pin.
Edit:
Can you send me an example of what that would look like... as far as separating the x and y and z?
-
Yes i understand. I first assumed you were talking about the probe pin and the extruder going up/down in the wrong direction.
Btw, also edit your homeall.g with the changes you've made in homey.g above.
