After a time away from my build I am lost.
I have a Jackpot TMC2209 board running FluidNC v3.9.5, WebUI v 3.0.0-a81F2
Is it advisable to update Fluid and the WebUI?
Because I had to relocate the LR, I believe I need to re-square the table. Can someone point me to the instructions to do that please.
I think our current recommendation is FluidNC 3.9.9. It’s worthwhile to update.
One note, Jackpot is now shipping V1 and V3 boards. The config.yaml is different between these boards, so pay attention to that.
The squaring documentation are here, it should apply to LR3 and LR4.

Thank you.
My squaring is only 1mm off.
I see there is a Update Button on the built in Fusion Screen. If I download the firmware, can I use that Update button?

I was able to update the firmware to 3.9.9. WebUI Version 3.0.0-5.
Little history and issue with Z Steps.
I am months into this build. All testing done with Fusion and the MPCNC v3.0 (Beta 3).cps
The Gantry tubes are 14.25.
The working table space is 1245X2460
@vicious1 Measurements for squaring are 2663 LF to RR and 2664 RF to LR. Only 1mm off. Tested cutting a 100mm square, all good.
Tested a round hole for putting in PVC pipe for clamping, Inner dia 14.40 Outer dia 21.00. All good
When doing a depth of 20mm, Z goes down to 21.78 to 22.00. Everything seems to be tight.
Any Idea of what I am missing?

Not sure what you mean with the two values there, is it tilted, or drifting? HAve you leveled your Z axis, surfaced your bed? 0.2mm is a pretty small value, for most projects Z is rarely that critical, if it is you need to surface the bed…and the top of your material before proceeding.
You need to make sure your probing is set correct?

Everything is square. Bed has been surfaced. Test PVC fits exactly as hoped just to deep.
Make sure my probing is correct? It what way?

I would like to add that I have done this same test probing (the v1e .5 probe) from the top of the work and from the spoil board. Same results both times.

Is your board secured really good? If not and you are using an upcut bit (like most of us do) the board could be lifting some causing you to cut a little deeper than intended. What DOC are you running?

DOC?
Depth of Cut. How much you are cutting for each pass.

That has got to be pretty old, are you sure it is not just dull?

Any chance the bit is slipping down in the collet?

Actually found the issue was with my configuration. Managed to fix it over the weekend. Doing test cuts now…..
