E 3d BIGBOX Duel head
-
@phaedrux
ok we finally have a print (Mr. Fuzzy). So there is some more fixing to be done but at least after 6 years sitting in my boss office broke it finally prints.i am going to need to clean up this print some so i can print the bottom piece i need for the duel head set up. right now the right head is working and left has melted out because i did not have the fan on.
the bed seems to raised in the middle for some reason so must figure this out as well.
At this point we can continue here or i can start new thread on print quality after looking over the history of questions first or other threads. also about the bed level thing as well.
what do you think? and any suggestions on the print quality or bed?
thank you for all your help with this project without this forum and your advice i would still be at it.
so thank you. -
Same recommendation as before:
Now you can try doing a mesh compensation run to see what the bed looks like. https://duet3d.dozuki.com/Wiki/Using_mesh_bed_compensation
Or calibrate the extruder, etc. https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+4:+Calibration/40
This thread is a bit long at this point. If after going through those you have more specific questions, probably best to start a new thread. It'll get more eyes on it as well. Try to include as much fresh info as possible off the hop just to get everyone up to speed with what you have going.

ok here we go again. i can't seem to get a good bed compensation grid down. i am usingM557 x05:250 y05:200 s40 which gives me 35 points and then use G29 S0 and all it gives me is four points and tells me the z axis cannot reach the other points? kinda lost here.

@phaedrux i do have height map file but no mesh file?

@phaedrux would this have anything to do with my Z stepper motors being wired backwards on the duet board ?
-
How do you mean wired backwards?
If you're getting a lot of skipped points you'll have to adjust your grid range to take into account the Z probe XY offset. Due to that offset there will be parts of the bed that the nozzle can reach but the probe cannot.
35 points isn't a lot of detail. It can be very informative to do a high detail probing so that you can see what the topology of the bed actually looks like. You can use up to 441 points.
Instead of using M557 S40 which defines the spacing of 40mm, you can use P# which lets you define the number of points to use and it works out the spacing for you.

@phaedrux
ok went back over everything and got the bed compensation to work and i now have 99 points for bed leveling. so not bad i think.now onto calibration the extruder with the test files.
-
I know this is not right i have something backwards but i know the wiring is correct i have checked it twice. i also think the end stop for x is not working properly either due to bouncing but no sure.

@gauravdhaka you might have posted in wrong thread

@gauravdhaka Please start a new thread.

ok very good board in and is printing, poorly right now but printing.
here is my files to the E3D Big Box with single head print for now. my config.g file. this works on my unaltered E3D big box printer with the Duel wifi board.; Configuration file for Duet WiFi (firmware version 3)
