Mesh Spoilboard mapping

Software / Firmware General
1

Hi all - i’ve got my LR4 running on a tortion table and i was wondering how flat is it and can i fix the high or low spots in software? I’m working on a script that probes the spoilboard at whatever interval and can compensate for high/lowspots by altering the gcode. (Using the telnet port to send and recieve commands in python)

Here’s a snippet of a 600x600 square i probed and generated some visualizations of the bed (i intentionally made point 1 a little high to emphasie the heat map.

Stay tuned!

Better (IMO,) to surface the spoil board

You have a CNC router. You don’t have to work around limitations in a bed as you would a 3D printer.

just surface the table or spoil board .

While surfacing is the answer I love this to visualize the spoil board. It can show you the difference so you know how much you’ll need to take off and what point to start at.

Still great if you have an uneven piece of wood or want to follow a slope. Check out Estlcam’s videos on how to engrave a computer mouse for instance. :slight_smile:

Absolutely! I’m not saying being able to map the surface doesn’t have its place. Just that for the purpose stated (compensating for an uneven spoil board), there are other (possibly more suitable) options.

I get that and i will. Was more of an experiment as to how close is it without cutting

Depending on the table, some shimming before flattening might be helpful too.

And that right there is all the reason you need to proceed…!

I would love to do this if you can make it idiot proof! :joy:
