I just noticed that the issues has returned. I was a little premature in hoping the issue had gone... I renamed "Pause.g" to "pause.g" but to no avail it appears.

Any other clue that would come to your mind?

@wieman01 Note that the dependencies and branches for the 3.5beta are not yet documented on the wiki, you may need to figure that out unless it's added before you start.

@o_lampe you want M500 P10 to save the tool offsets.
at least with my toolchanger that i used to run (and its the same with the E3D toolchanger) all the tools were relative to the z probe. So the z probe had no offsets and each tool was offset from that using G10

@boa said in Question: BL Touch Probe Offset & Mesh Bed Leveling:

@wieman01 Y range is limited only from one side. Y=0 coordinates can be reached by bltouch - it just moves nozzle to position Y=36, and then proble is at Y=0.

But.. if nozzle can go only to Y=350, then probe can reach only points with Y <= 350-36.

So M557 would have Y range Y0:314, as any higher Y is out of reach of probe tip.

Thank you, that makes sense. I'll change the settings accordingly. This could be reason why bed leveling appears to be slightly off.

@jay_s_uk

Thank you, that is good news. I'll keep an eye out and see what I can find when the first beta comes out.

@gixxerfast said in BL Touch not working:

Which version of RRF are you using, ver 2? I can't see that you've mentioned it.

EDIT: OK, so you're using RRF 3.3

Then I think you should config the BLTouch differently:

Have you read this bit, "Software setup (RepRapFirmware 3)" for the https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe

Either I'm a sloppy reader or I can't see that you have the M950

AS in this example:
2. Create a GPIO/Servo pin index using your chosen control pin, for example:

M950 S0 C"io7.out" ; Duet 3 MB6HC
M950 S0 C"io3.out" ; Duet 3 Mini 5+
M950 S0 C"exp.heater3" ; Duet 2 WiFi/Ethernet
M950 S0 C"duex.pwm1" ; Duet 2 WiFi/Ethernet + DueX2/5
M950 S0 C"!exp.heater6" ; Duet 2 WiFi/Ethernet + BoB
M950 S0 C"zprobe.mod" ; Duet 2 Maestro

Thank you, that did the trick! I must have overseen that section and used outdated sources. There are so many out there, you don't see the wood for the trees.

Also my deployprobe.g and retractprobe.g files referenced P7 rather than P0 as was mentioned in one of the guides. But these files reference the probe input rather than the heater, so P0 is the correct setting.

These are the correct settings and corresponding files:

Thank you for your help! You made my day!

@zapta said in Question: Best settings for maximum torque of stepper motor:

@wieman01, can you improve the properties of the clay? E.g add water?
Yes, you're right, in principle that is an option, however, in our case the viscosity of the material we are using cannot be changed for various reasons I won't bother you with. 🙂

I have order a geared stepper, let's see if that works out for us.

@phaedrux

Thank you for taking the time! I had it in there before and removed it afterwards. Strangely with the changes made as suggested by @jay_s_uk it works regardless. But I will put it back in there, so it does not create a problem later on.

Thank you, both. Now I got it.

I just tested this during a live print and it worked perfectly thanks to you. The print stopped when I triggered the endstop and paused until I hit "resume".

@wieman01 said in G29 mesh probing & bed compensation with 4 Z-motors:

Thank you, I saw the post earlier and followed it to the letter. Bed leveling now works and I'll post my "bed.g" later.

Is there any way I can increase the maximum correction of 1mm? This is a clay printer with a wooden bed, so my tolerances are of very different nature. 🙂

The web interface displays an error message because of the set limit of 1mm.

Other than this I think I am done thanks to your help.

On the M671 the S parameter set the adjustment amount (if left of it defaults to 1mm) but remember that with 4 screws you run a serious risk of warping the bed you can of course run the routine several times and it will converge.

Thank you, my friend. That is perfect. Warping won't be an issue, my printer is designed such that it should withstand greater differences well enough. If not, I will try again. 😀

This is a working copy of my "bed.g":

@Phaedrux said in Question: Connecting extruder motor(s) using regular Nema17:

@wieman01 said in Question: Connecting extruder motor(s) using regular Nema17:

correct?

Correct.

The extruders are different than other axis because each extruder is treated independently. They may have different motors and are not commanded in a coordinated way like other axis are.

If you don't specify the parameters for each extruder you may end up with an unknown default value and unexpected behaviour.

Thank you, Phaedrux, that makes sense now. Will make the changes as agreed. I think I should have a very solid baseline now for my next endeavor when my capacitive Z probe arrives (NPN NO).

Thanks to all of you for bearing with me. These last few days have been very insightful and crucial to my project.

Thank you, @fcwilt & @Phaedrux, that was very helpful.

I'll let you know how that goes.

@Phaedrux Ok got it working had to update duetwifiserver.
Thank you for all your help!!👍

Q1: I may in fact decide to use a belt instead, thank you. Great thought!

if you have enough Vin and will run the motors at a slow speed*, you might get away with 3 motors in series on Z - and 3 would likely be a better choice than 4, as 4 would technically over constrain a plane.

*) ref the emf calc over at https://www.reprapfirmware.org/

I will give two motors a shot to begin with. Let's see how that pans out first. I have to test it first.

Thank you for your thoughts!
