Yeah actually I need to change that for the lr4 as well.
You should set it to Z-200 or however tall your plates are.

The tall plates are ~130mm of Z, so it should be fine to use that instead of 80

Is this “run_amps” and “hold_amps”? They are presently set at .800 and .500 respectively for all motors.
Change “hold_amps” from .500 to .700 on all 5 drivers. That should solve the motor problem you are having.

I gather this is re. Marlin. (?) A benefit of FluidNC on Jackpot (I’m pretty sure that), I can re-home and it does not clear out the probed value (same behavior as for X and Y). The zeroed values/probe value (aka “work space” coordinates) don’t get erased by homing.
Looks like I’m having a success here but we’ll see what happens when the end gcode runs. I’ll be wise to add lead-in to all my cuts - the endmills don’t penetrate ice like you might expect.

No issues. Pretty darn excited about this!

Dude, you rock. That’s awesome.
Just days away here I think! Question for you all…those little collars on the bits I got from Ryan - are they reliable for setting the bit “stick out length” (within a half mm or so)? Tonight I’m going to dial in the Z horizontal-ness but intend to rely in those collars if I ever switch out the 1/8’s for a little 1/4" run here and there. It’d be great if those collars are reliable for resetting the machine to run the 1/8’s.
For sure, you need to set them initially after that they should not move.

Insofar as I have checked, as shipped, they are accurate for the different style mills as well. V bits, 1/8, 1/16 single and double flutes.
That said, they can and will shift over time, especially if allowed to get hot (probably not in your use case, lol.)
I tested the 3 types listed above using RepRap firmware probe commands where it just reports the probe height and doesnt reset zero, and 2 examples of each type of mill all reported within 0.13mm of each other. (Sheet of paper.)
Probes were repeated 5 times, values averaged, with larger variations theown out. Some of the sets of 5 had larger set variations than the final set…

The bits are in place, the Z leveled and test file CAM (with lead-in on all cuts) is complete and have “air cut” successfully. Tomorrow I’ll slip a slab under the gantry (and then pour something from the pantry)!
I’ll take video for sure and post the milling but then will have more video being recorded which I’ll stitch together so you all can see the ice go from 400lb block to 2" logo’d cube.

Heck yeah, can’t wait.
Learned a couple of things. Maybe three things.
Halfway through my laptop went to sleep. Which I think explains why the LR took a break. Walking laptop resumed task. File was running off of the Jackpot though so I may be mistaken.
“Lead-In” doesn’t at all do what I thought and was if no value here.
I can increase the z step down for sure. This was a conservative 2mm for a final depth of four. I think I need to go at least to a final depth of six but bet I can do that all in one drop. ReCAMming now for test number two.
The Makitas throw some heat so while these tests are in a 12 degree garage (Celsius) I think results will be better on the minus side of the thermometer. The heat caused some surface meltwater which seeps into the snow in the engraving and sort of makes it go translucent.
Stay tuned for test two!

24 custom CNC engraved craft ice cubes in under four minutes. Tonight I go to sleep with a feeling of tremendous success and bright dreams for the future of this machine and those that follow. $20,000 CNC machine? Pffft…who needs that?!
Thank you to EVERYONE here that’s helped me reach this point. I feel so, so great right now. After all that work, all of the things that have led to this…a trip to Colorado where I got to meet Heffe, the adventures hauling the 600lb ice machine back to Canada on top of my truck, the pain and frustration of learning the walk in freezer I built was actually just a refrigerator, the freezer “fix” finally getting going and being way too flipping cold to work in, the massive cleaning that had to take place in this “once a wood carver’s garage”, the planning, website building, packaging explorations…it’s been quite a journey since March but here we are. Here I am.
I’m now at a loss for words. Said too many already.

Amazing. Congrats on your success! Where’s the dust coll… oh wait
