Hang printer - Print stops with mesh leveling
-
@phaedrux
When sending the G30 command the the print head doesn't move and the ui for moving the axis comes up. The buttons work to move the print head. I use those buttons to set the height and hit ok. Then the head moves up to the dive height.When sending G29 there is no motion only errors.
When it was working it would move to the location for each probe at z=H parameter in M558.
I wonder if the lack of motion at the start of G30 is an indication of what is causing the G29 to fail?

That's exactly how M558 P0 and manual probing works. You have to manually move the nozzle to touch the bed. So G30 sounds like it's working.
Once you've done that G30 and set the Z0 position are you able to jog the print head around manually?
With M558 P0 set, using G29 should indeed prompt you to jog down at each point.
And just to confirm, that's with this set?
M558 P0 H15 F120 T6000
M208 Z-5 S1 -
It moves around fine after g30. I can move it in a very large space and when I send it back to home it is right to the correct spot.
The behavior was the same with:
M558 P0 H15 F120 T6000
M208 Z-5 S1
and:
M558 P0 H5 F120 T6000
M208 Z-15 S1Tried both.
-
Ok, so G30 is working, but G29 still complains that it can't reach all the points.
At this point we don't know if it's a problem with the hang printer kinematic, the SBC DSF implementation, or a firmware problem, or some combination.
Far as I know, you're the first one trying this.
Things to test to narrow it down would be to try testing in standalone mode without the Pi as we discussed before. Though this would require running an ethernet cable up to the Duet.
-
@phaedrux Was in the area and stopped by real quick. Tried running a G90 or G91 right after establishing the home. Tried this with dive bigger than minima and smaller and with the Z minima set to 0. All cases the G30 worked but the G29 still did not.
Next step is to connect direct to duet with cable.
The dive is currently set slightly larger than the Z minima. Here is the current config.

Ok connected direct to duet. Pi is unplugged from it.Connected to it.
Used G1 S2 commands to tighten individual axis to get to home location.

Can you try with a different M557 command?
Try

@phaedrux
That one still says it can't reach the points with same procedure as before. Just many more points.g29

and so on. -
Thanks for testing. At this point we will have to wait for DC42 to return from vacation to be able to investigate further.
-
@phaedrux Thanks for feedback. Sorry for being a pain with this. I've run into the limit of my knowledge.
Interesting test Tobben suggested on discord. I set the home position around z150 and sent a g1 z-100 command in absolute mode. It allowed it. The lines didn't maintain tension which is not too surprising asking for something so far out of norm. But there was no error. Hopefully that helps with diagnosis.

Does anyone else on the discord server have a hand printer on Duet 3 running 3.3 that can confirm whether G29 works for them or not?
-
@phaedrux I copied the basic delta config for motors and set home and tried G29 and it worked unless the M557 was too big then it threw the same errors. Converted back to HP config. Tried G1 movement commands in absolute mode well past the M557 limits and it was allowed and the printer moved to those locations. The G29 still threw errors for all points.
-
@phaedrux I haven't seen another duet3 HP other than the V4 Tobben is working on but I asked to see if someone responds. Looking forward to what DC42 thinks. Hopefully the book above gives the clues needed. hehe Thanks for your help.

@shinomori I've looked at the code and the limits that apply are those set by M208. So make sure that your limits are sufficient, for example M208 X-300:300 Y-300:300.
I also notice that in your config.g file you do not hide the U axis. This may be because you need to move U (aka D in Hangprinter terminology) manually sometimes. However, it means that RRF will check that D is within limits too. So I suggest you hide the U axis using M584 P3 when you don't need to move it manually, in particular when running G29.

@dc42 The only time I use the U is with a g1 s2 command for individual axis move to tighten the lines for initial setup. Does that still work with the axis hidden? If so I can hide it all the time.
That makes sense that it is out of limit. I've tried it with XYZ but not U.
I'll get over to the printer to test in the next couple days. -
If you need U available most of the time, you could setup a mesh.g file that would be called when you send G29. Inside that macro you could hide U, do whatever preparation you need and then call G29 S0 to probe the bed and when it's done, unhide the U axis if needed.

No. You would need to un-hide the U axis (M584 P4) before using that function, and hide it again (M584 P3) afterwards.

Error: Too few points probedIf I try to move the machine with g1 commands in the Z the behavior is very chaotic. Small movements the printer does not move but the toolhead position that is reported in the ui is what was asked for and then on some commands it randomly moves, but not to location asked for. Small downward motions are ignored and then suddenly it crashes into the bed.
If I run M584 P4. G1 commands result in expected motion. G30 ui buttons work and it move up to z6.0 after hitting ok. G29 still throws the error.
