Hang printer - Print stops with mesh leveling
-
@shinomori said in Hang printer - Print stops with mesh leveling:
Mesh is set through ui to -100 to 100 on x and y with 100 mm spacing.
Yet your config has M557 R400 S200.
Can you send M557 in the gcode console and see what it reports back?
I'm not familiar enough with hang printers to know if it uses a delta style radius or a grid style like a cartesian.
You might also be the first person doing mesh compensation with a hand printer on 3.3+SBC.

Grid: X-100.0:100.0, Y-100.0:100.0, radius -1.0, X spacing 100.0, Y spacing 100.0, 9 pointsI am also not sure which mesh style is correct. The build area ends up being circular which is why I have a large radius mesh in the config. I am setting a smaller one with fewer points on the web ui for testing and it asks for grid style coords.
With the older FW it would run through the points with either radius or grid.I suspect there are alot of firsts on this build. Unfortunately I haven't learned how to dig through the git or firmware to figure out what is happening underneath myself so I really appreciate the help.
So on interesting thing happening that I don't know what to make of. If I set the height with some paper and then do a g92 to set zeros. I can move the print head all over 200-300 mm in all directions and then send it back to zero and the tension on the paper hasn't changed. If I do a G30, then try to go to Z0. It is over half mm too low.
-
Can you send G31 and see what it says? I don't see one in your config.g so I think it's using default values which would explain the differences when using G30. This might also be what is messing up the G29 since it uses it as well.
I suggest you add a G31 command to your config below the M558 for the probe definition.
G31 P500 X0 Y0 Z0 should do it since you're using the nozzle tip and manual probing.
You can also check for syntax errors in your config with M98 P"config.g"

@phaedrux
Ok updated config with g31.G30 now ends up with good spacing afterwards. Good call.
M98 returns no errors. G29 still returns error for all points:

I don't see where you specify M208 for X and Y.
The error is because the probe cannot reach the XY position as it is outside of the min/max for X and/or Y.

I was just wondering if that might be it. Thanks!Is there a way to set Radial limits instead of grid?

I think if you want to use radial limits then don't specify a M208 for XY. I don't think they have limits other than Z set for a delta. I assume that if you set a square limit range in XY you'd either have the corners protrude into areas that the effector can't reach, or you would have to keep the limits within the reachable radius and you'd loose some travel.
Then for your M557 just use the radius instead of a grid.

So a hang printer is limited to a round area like a Delta?
For a delta there is a M665 command somewhere which specifies, among other things, the delta radius.
I would think there would be some command to specify that radius for a hang printer.

The printable radius for a hang printer is set in M669 P. So a bit different than delta.
-
@phaedrux
Yeah the radius is in the M669 command which seems to be the same as the M665 for delta.But either way with or without X Y limits in the M208 it still doesn't want to manually probe the points with G29.
We do plan on getting some type of probe eventually, but the budget makers want to see it using a mesh first. We also are looking at different probe options between a physical sensor or a laser of some sort.

I cannot find that in the "gcode dictionary".
It lists the type (hang printer) for M669 but I cannot find the other values for that type.

@fcwilt It's all in the link for the hang printer wiki.

Try to avoid using the GUI to set the spacing etc, just send the M557 R S command from the console.

Found it.
Shouldn't the items related to M669 also be in the gcode dictionary along with all the other types?

At this point it would be helpful to be able to test in standalone mode so that we could narrow down if the problem is with the firmware or with DSF on the Pi.

@phaedrux
That would be with direct USB connection?
Or is there a way to do it direct with network cable?Mounted on the ceiling connecting through wire with laptop is a challenge. Our print area takes up a 13ftx13ft space.
