    • RE: Mesh Calibration Issues (Duet Maestro 1.0, FW 2.02, BLTouch)

      I don't know why it took me so long to realize I should be using my feeler gauges to level the platform. 😥 But here's the latest. Now that it's mostly flat, I'll worry about raising it to 0-ish tonight. Now time to start increasing resolution.

      Edit: ugh, just re-homing the Z should get it to zero-ish. I'm clearly firing on all cylinders today.

      My Z Probe section:

      ; Z-Probe
      M574 Z1 S2 ; Set endstops controlled by probe
      M558 P9 H1.5 F120 T6000 ;A5 B1 ; Set Z probe type to bltouch and the dive height + speeds
      G31 P500 X-25.3 Y0 Z0.675 ; Set Z probe trigger value, offset and trigger height
      M557 X25:200 Y25:200 S20 ; Define hi-res mesh grid <-- OMG I didn't know about the "P" argument... So many maths could have been saved 😖
      ;M557 X35:365 Y35:365 S330 ; Define low-res mesh grid

      For the first time in 2 weeks, I made it to layer 5 on a print with no errors.

      That elation tho.

      Thank you guys for the help. All of the combined knowledge you guys shared should be part of a book, or wiki, or something for Duet, cause that was extremely helpful and useful. Seriously, @Phaedrux @grizewald @Veti thank you guys!

      The glass combined with the solve on the X-gantry made a massive difference!

    • RE: Ongoing Mesh Level Compensation issues

      @Veti I was only using the 9 points as a quick sanity check for corners (since that's my only manual adjustment points). Not intending to stick with 9 when actually printing. But thanks for the heads up.

      buahahaha!
      Resolved with the info on the following page.
      https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors#Section_Example_for_2_motors

      That made everything work like butter. Yes, tramming was the major issue. I'm no longer even using mesh compensation, just the z-screw leveling. Immediate improvement and adhesion. Now I just need to make sure I'm actually at proper nozzle height, since I appear to be scraping off levels with my nozzle.

      Thanks for the tips all.

      ugh.....
      5f8180ed-85b9-4906-86c4-b6359ad91215-image.png

      still no adhesion.

      Mirror surface with aquanet. I simply do not understand wth is going on.

      I'm trying to print in the center of the bed, but nothing sticks.

      For ref:
      known-good PLA @200C
      Mirror bed with Aquanet at room temp (works on my TronXY XY-2 no problem)
      Layer height 0.12mm
      Initial layer at 0.12mm
      0.4mm head
      print volume is 380^3

      bed is much more level, but same symptoms.

      Simplified the sample size just to be able to iterate faster. The 380 X,0 Y corner is still a bit out, but overall much better. Still no adhesion at anywhere other than the 0,0 corner.

    • RE: Ongoing Mesh Level Compensation issues

      @droftarts Thanks for the notes. I realize it's possible for my machine to need tramming, just not sure how I can get 0.5mm of accuracy on any tools I have, when I do not have a fixed frame of reference to measure against. I'll investigate though.

      @greenlee Didn't know about G29. Adding it to my print start g code in cura.

      @aidar Cool tip, I've updated this value and will report back.

    • Ongoing Mesh Level Compensation issues

      Re: [Mesh Calibration Issues (Duet Maestro 1.0](FW 2.02)

      I finally got some time in my life to go back and continue working on my HyperCube. I designed a new x-carriage/extruder mount combo block that I'm quite happy with, and am now trying to get my printer to finally work. In the post I reference above, I got realllllllly close prior to the x-carriage breaking and wiping out a lot of my progress.

      Current problem
      Between X20Y20 and X20Y200, I can lay down a straight line of PLA essentially without issue. Anywhere else on my print bed, and I get no adhesion.

      Current Equipment

      • Bowden-type hot end
      • BLTouch
      • Mirror glass print bed
      • Lots of AquaNet!

      The question
      Is there some way to ensure I have mesh leveling operating correctly? It seems very odd that I am unable to get anything to adhere to glass with as flat a surface as the one attached.

      I'm not even getting scraping, the bed seems too far from the head, but not everywhere, leading me to think mesh compensation isn't working.

      config.g zprobe section
      ; Z-Probe
      M574 Z1 S2 ; Set endstops controlled by probe
      M558 P9 H1.5 F360 T9000 ;A5 B1 ; Set Z probe type to bltouch and the dive height + speeds
      G31 P500 X10 Y-25.3 Z0.40 ; Set Z probe trigger value, offset and trigger height
      M557 X20:320 Y20:320 P8 ; Define hi-res mesh grid

      Open to thoughts, please!

    • RE: Mesh Calibration Issues (Duet Maestro 1.0, FW 2.02, BLTouch)

      Well, I found tonight that I am a moron. I had forgotten two X-gantry retaining screws to hold the gantry rods in place on one side. There was a non-trivial amount of torsion on the print head as a result. Wondering if that was the source of the "scraping" of the print.

      Second, I'm getting closer now that my mirror arrived.

      Going to try printing in a bit.

      @phaedrux I'm so frustrated cause I feel what you're saying, but nothing frigging sticks!!!

      Blue painter's tape? Yup, tried it. Half the 400mm^2 bed is covered in it, and glue stick, and hair spray. 😠 Obviously I didn't do them all in one go, but one after another. Throw the tape away, try another round. I can barely get one line to stick, but the second the nozzle changes directions, the print lifts off the surface. I've tried print temps from 190-210, and bed temps from 45-65. 🆘 Last resort is glass. If that doesn't work, not sure what I'm going to do.

      @grizewald I updated my firmware to latest, that made my results look much more like yours.

      Bed compensation in use: mesh, comp offset 0.000

      Going to try re-printing now, even though my bed is still unlevel af.

      Here's hoping. Well, here's hoping the mirror gets here soon so I can clamp it to the bed and be done with this stupidness. 😌
