Introduction + Makerverse Questions on 2021 M2

Hello friends,

Quick introduction, I’ve built an XL Frame m2 in my garage this week and I’ve got it calibrated to within 3mm which feels pretty good, may do a 3rd edge calibration to see if I can tighten up more. This is my first go at CNC but have a technical background and also handy with woodworking.

My biggest life lesson learned in my build was that garage floors have a non-trivial amount of slope towards to the garage doors. From one leg to the next, I had to shim the leg closest to the door with a 2x4. I also had to shim the front of the 3ft legs with a thin piece of flywood. Super level…but man, that was a lot of shimming.

To do’s:

  • Since I’m not against a wall, I need to attach some supports to the garage ceiling and fix the vertical supports to that.
  • Secure the 3ft legs to the floor in same way to ensure it doesn’t move due to getting nudged in the garage.
  • Trim up shims to fit a smaller footprint and attach them to the frame since this is a permanent position.
  • Actually cut a project!

Obligatory picture! Feedback welcome!

Alright, now for the questions that are mostly centered on Makerverse.

  1. When I hit the home button to return to 0,0 it works great…except my z axis. That thing dives to 5mm. I’ve not run the router yet so it’s just sliding the bit across the wood, but it’s not immediately clear how to modify my home routine. How do I zero this out?

  2. Calibration was something of a chore, but I have a good idea of the process now. How often is one suppose to calibrate the machine? Before every job? Is it dependent on runtime? Do you have to do all of the tabs? What is the best strategy for maintaining calibration?

  3. Is Makerverse the only option for interfacing to the machine?

you set the zero for the Z axis, and it should move to that point.

you should only need to recalibrate when you do a panic stop or turn off the
system while it moving, when the chains come off the sprocket or sometimes when
you do a software update (or hardware change). A few seconds after it stops
moving, it saves where it is and at that point you are good

when you do the calibration, there is a point where you have extended both
chains to a known length. At that point there is a tooth on the sprockets that
is in the 12 o’clock position. mark the link of the chain that is at that point.
Unless you change the hardware significantly, you should be able to get back to
that point by resetting the chain lengths (exact deatils of that differ from
makerverse to other software

  1. Is Makerverse the only option for interfacing to the machine?

different hardware requires different software to drive it. I think the
makermade uses the duo board and requires makerverse (but others here are more
familar with that hardware than I am)

Ha, my issue was that I needed to invert it. Inverting it, it would raise to 5mm when traveling to 0,0 for x and y.

Thanks for the tips on calibration! I actually ran edge calibration a few more times and now have my accuracy to 2.4mm so a smidge better.

Now on to cutting something!

So I’ll just post my next picture here and another question instead of a new post.

So my first cut came out great except a few spots where the z axis went deeper than it probably should have. Any idea what would cause this?

Well, I’m a dumb dumb. User error related to the bit I set in the gcode :face_with_open_eyes_and_hand_over_mouth:

Another thing that can cause this is the bit working its way out of the collet chuck
