Hey everyone, Im looking for ideas for for mounting my 1LC and Hemera Revo hot end. I will be designing a bracket/mount in fusion360 to attached to a 2020 + MGN9 linear rail as my X-Axis. But that is for me to figure out.
I'd really just like to see some pictures of the 1LC mounted, wired, you know...the sexy stuff. Haha.
I recently purchased a 1LC board from my local dealer (digitmakers in Toronto).
The board I was provided was the 1.0 board.
I've heard that the 1.1 board is needed to utilize an accelerometer. If true, Should I be asking for them to replace it with the 1.1 board?
When I get back to my office later today I may have some further questions to grow my knowledge of proper setting of my config.g as I was experiencing skipped steps.
Thanks so much. It is as quiet as I could ever imaging. Incredible. Now I just need to tune it.
So I had a Duet Wifi board die on me. Admittedly it was a clone (I bought two for backups in case something happened to my genuine boards). Well, clones suck. They work temporarily, but suck in the long run.
So when it died, I decided to buy two Duet 3 Mini 5+ as I like the price by comparison to the Duet 2 Wifi and I wanted to be up to date.
I am proud that I was able to port my machine over to the Duet 3 firmware and new board without having to rely on this forum. I took my time and read over all the instructions and data. Took me a few days to learn the ins and outs of Duet 3 firmware, I am up and running, and all is good except one thing....noise. The D3M5+ is quite a bit noisier than either my older genuines D2Wifi, or its clone.
Is there something I should be adding to my Config.g to quiet it down?

I have fixed my problem. I took apart the printer last weekend and re-assembled it. Moving some of the extrusions around (like rotating your tires) and re-squared everything up. Found one spot that seemed a but off so I positioned it with a small gap and tightened things up with a metal 90 degree corner.
I also noticed that my bed.g file looked like this
M561 ; clear any bed transform
G29 S2 ; Clear bed height map
; Probe 2-points
M401 ; Deploy probe - deployprobe.g
G30 P0 X90 Y115 Z-9999 ; Center Left
G30 P1 X125 Y115 Z-9999 S2 ; Center Right
M402
But there is only one 7 axis on this printer. So I deleted everything expect the M561 command.
Between those two things, my printing is back to normal. I wanted to thank everyone for their suggestions.
deleting the text in the height map did solve the latest issue.
But now I am having problems with the Maestro board connecting to the network. If I turn the unit off, then back on, many times now it won't connect. I have to turn it off, unplug it, plug it back in and turn it on...and even thats 50/50.
All my wifi units work. So Im going to swap the cable, as well as review the access point it is connected to. But I have a pretty extensive knowledge of home networking from my home audio and automation days, and am confident regarding my network.
Like I mentioned, I have a backup Duet 2 Wifi board that I can use if I think something has

Well, I don't even know where to begin. As I previously posted on Saturday, I had gotten close to fixing my issue with my bed and probing, but was going to walk away for a few days (canadian long weekend).
I've come back to this machine now with a clear mind and a few ideas.
I turn the machine on and warm it up. This machine is using the Duet 2 Maestro, and 2.05 firmware.
I hit the home button:
Print head moves X and Y to their endstops, then to the center of the bed. The BL Touch probe is deployed properly, touches the glass surface twice and reports back the correct z-offset and moves the head up to the expected position:
But as soon as it stops its motion the head position for the Z-axis turns from 11.77 to this:
Now the machine is locked up and I cannot move the head with the DWC controls or macros.
I'm starting to think that the Maestro board is pooched, but I really have no idea. I have a backup Duet 2 Wifi board here that I can replace the Maestro with, but I would rather know for sure.
Im taking a break from it. I have other working machines and need to take a break from it. Get back to it tomorrow.

2.05 on all machines. Too much on my plate. But one day I will simply do all machines.
I have now disassembled the bed platform, turned it over, and re-secured it. removed and rotated the build plate, re-secured it.
Its amazing how much time you can lose on a mechanical issue.
@Phaedrux regarding the G92 Z0 / G30 S-1, I did this earlier today and started an excel spreadsheet to track the issues. I didn't finish it as it was immediately apparent that the bed was sloping downward at the front (Yaxis), just like the mesh shows. X Axis was relatively stable down to 0.015mm.
Still working on things.
All of this I very much understood. This bed was never like this before this week. It is warpy, but not slanted. What I found at the beginning of the week was that the mesh seemed to over compensate for the warpiness lending to rough first layers.
Removing the mesh certainly helped at the beginning of the week. But something mechanical has obviously happened during the week to lend to this major slant problem.
What I can't wrap my head around is how the nozzle, which is a relatively fixed distance from the BL Touch pin, can be squared up and safely touching in each corner, and then the mesh turn out so slanted.
Sunken center, and warpy dips....fine. But the nozzle safely touches in all four corners and it is not represented as such in the mesh.
The weird part is, nothing has changed on my printer in the last year really. It was printing fine earlier this week.
I will agree that I am not the type of person that lets problems persist. I like to know the why of things.
So here is how things played out on this machine:
Was printing last week as normal with a mesh. Not perfect, but was printing. But had higher first layer failure rates than I was willing to tolerate.
So I disabled the mesh and when with manual leveling. It worked decently. In the mean time I was reviewing things about the BL Touch and mesh leveling to make sure I hadn't overlooked anything in the past. A refresher.
During the time my printer was constantly going. Not failures, great prints.
Then all of a sudden I was having first layer issues. So I decided to go Mesh again, and "crack the code".
Well, I haven't cracked the code yet.
I just ran G32 three times in a row, adjusting the bed after each. I'll post a picture of a print that I ran for the first 2 layers. Clearly their is something wrong.
@deckingman @Phaedrux its a bit of both.
Something happened in the last 6 days that caused those perfectly smooth layers to be way out of whack.
I was pleasantly not using mesh leveling. Just homing and leveling my corners. Then boom, all of a sudden that didnt work any longer.
So I have been trying to get it back ever since.
Level the corners....doesn't work.
Ask for a mesh....way out of whach.
I can fake it by using the mesh to make the adjustments to get a flat mesh....but is that a good way to do things? Probably not.
Guys, I am punch drunk with this. I've been at this all day. Loosened, cleaned everything. Measured everything. Changed out the BL Touch. Replaced the Pom nut on the z axis. Reviewed the Z axis flexible couple, nothing wrong with it. Tightened it up. Used my digital calipers to measured off the x axis 2020 ext to the bed. Flat.
My latest go had me going back and forth between Corner 1- Corner 3 and Corner 2 - Corner 4. To all my measuring they are spot on.
I then just went up and down 5 times on each corner to make sure the grip on the paper didn't change. It didn't. I probed the center of the bed 10 times, certainly well within tolerance.
Leave it as all four corners are repeatable and snug the nozzle well.
But as soon as I do a mesh level:
Bewilderment is the only work I can describe it.
