Problems with Duet 3 Mini 5+ WiFi
-
@phaedrux I'm going to use my old motors for the time being. They are working just fine. I have X and Y wired up without any issues. If you don't mind, could you help me with the dual z? I want to add the second motor to E0. I read the documentation a few times and I'm not sure if I'm understanding it correctly. My full build area is 310x370.
Again, I really appreciate your help. Thank you very much.

Yeah those Moons motors just aren't the right specs for a 3d printer. Inductance is too high. Not sure what else to say about that.
To add a second driver to the Z axis you need to tell it that the Z axis has 2 drivers. This is done in the M584 command where the drivers are mapped to the axis.
The mini 5 doesn't have a driver labeled as E0 as far as I'm aware, so assuming you mean driver 3 on the mainboard.
M584 X0.0 Y0.1 Z0.2 E121.0
Would become
M584 X0.0 Y0.1 Z0.2:0.3 E121.0Now when a G1 Z command is sent, both Z motors will act as one.
Now that you have dual z axis you can do fancier things like this: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_auto_levelling
-
@phaedrux Thank you. I don't know why I thought it was labeled EO. When looking at the samples on the page you linked I'm not sure how that gets setup. I'm sorry I guess I'm a little slow here.
-
You mean the auto leveling? Did you see the examples?
https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_auto_levelling#examples
You tell the firmware which drivers are in each axis.
You tell the firmware where your lead screws approximately are.
Then you setup bed.g to probe near those lead screws and it makes the correction. -
@phaedrux I'm not understanding exactly how to figure out the variables given the example. G208 and G30 especially. I see the explanation and it makes sense, but looking at the measurements on G30 don't make any sense to me.

Could you elaborate a bit on what it is you don't understand?

Well your M208 is already set for your bedsize, so that doesn't change.
The points for the G30 in bed.g are going to depend on where your leadscrews are. If it's a cartesian it's going to be a point on the left and right side of the bed where the probe can reach.
-
@unforgivenll Okay, is this what it should look like?
M584 X0.0 Y0.1 Z0.2:0.3 E121.0E1
M671 X-25:335 Y0:0 S0.5 ; leadscrews at left (connected to Z) and rightG28 ; home
G30 P0 X25 Y155 Z-99999 ; probe near a leadscrew, half way along Y axis
G30 P1 X285 Y155 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors -

M584 X0.0 Y0.1 Z0.2:0.3 E121.0E1
The E1 at the end isn't right.
@unforgivenll said in Problems with Duet 3 Mini 5+ WiFi:
M671 X-25:335 Y0:0 S0.5
Y0:0 is only correct if Y0 is the center of the bed and that's also where the lead screws are located. If Y0 is the front of your bed, and the lead screws are in the middle, the Y value would be approximately half your Y max value. Does that make sense? If your Y position in your G30 commands is correct, it should be Y155 as well.

Usually they are same or similar.

bed.g @fcwilt My Y min is actually at the back of my bed. I don't know if that makes a difference. I think I know where this is placed in config.g but I have no idea where it is placed in bed.g. The E1 is a typo, I'm on my phone and was copy/pasting.
So it should be ?

G30 P1 X285 Y155 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motorsI asked where to put the new bed config info because there is some there already. Do I keep what's there or do I replace it with the new config?

I like to keep related things together.
So my bed.g file has all the commands needed to level the bed.
Some of the commands in my bed.g are often put in config.g but I don't do that.
The M584 should stay in config.g since it is fundamental to the printer working.
The M671, G28 and the G30s, can all go into bed.g
There should be no G28s or G30s in config.g ever.
And if there is a M671 in config.g, remove it and rely on the one in bed.g
Frederick

@fcwilt Thank you. Here's my configs again if you want to look at them. I'm working on sensor less homing and setting my Bltouch height from the bed next. It will probably be awhile before you hear from me again as I have to wait for some parts to proceed. I'm sure you won't mind the peace. I appreciate everything.

You have a G29 which some folks do include but bed.g is really meant to handle bed leveling. G29 is related to Mesh Bed Compensation - something else entirely.
G30 executes bed.g and should level the bed.
G29 executes mesh.g, if found, and it should create the height map needed for Mesh Bed Compensation.
And creating the height map should only happen after leveling the bed. Also prior to creating or loading a height map you need to set the Z=0 Datum using a single G30 at your chosen reference point. Many folks use the first point of the height map mesh, some folks (like me) use the center of the bed.
As I mentioned I like to keep related things together so my mesh.g file has only the commands needed to create the height map.

@fcwilt I'm sorry I didn't realize that. I also realized for some reason I had 155 stuck in my head for Y center, when it was x center. I changed it to 185. I didn't have a mesh.g so I created one and added the G29 there. All the commands were added by the auto config. It was far as I had gotten before I started changing it with you.

Well you cannot put G29 in mesh.g because G29 executes mesh.g - so it will likely just go round and round.
You need to do something like this
G1 Xaaa Ybbb ; where aaa and bbb are for the point you have chosen for the Z=0 Datum reference point G30 ; this probes the bed and sets the Z=0 Datum M557 Xaaa:bbb Yccc:ddd Pe:f ; this sets the grid that is probed to create the height map - you need to chose values for aaa,bbb,ccc,ddd,e and f G29 S0 ; this creates the height map - notice the S0 -
@fcwilt Thank you again. I'm clearly over my head here. I thought I had a handle on this before I started. Unfortunately I have a lot of money plus time into this project, so I can't walk away from it. I'm feeling a little overwhelmed at the moment. I'm 45 and just started using 3d printers a little over a year ago. I don't have any background whatsoever in CNC, CAD, or 3D printing (maybe a tiny bit in general electronic/soldering). Anyhow, I'll try to implement your advise when the new parts come in. I'm waiting on a build plate and have yet to setup/order a custom heater. I appreciate your help, patience and time. Hopefully I can make some progress on my own when I get the new parts. I'm not feeling real confident at the moment.

It's really not so bad. You can get as fancy or simple as you like. And once it's setup, the hard part is done.
45 isn't old. You're probably half the age of some of the people here.
Read lots. Sleep on it. Try and implement it. Ask questions. We will get you there eventually.
