Hi, i am having trouble related to z leveling. I have had my lr3 for a while now and used it for fullsheet cutting. Always 2d so z level was not that important to me.
I have now build a new table from an old table tennis table which works great. However, i need 2.5d cutting and thus the z axis need to be accurate.
I tried z leveling a couple times now, but i cant seem to get it to work. I probe as stated in the lowrider manual and note all the values.
For example: Z2 was at 129.0, Z1 at 130.2. I then entered m666 z1.2
The eprom saves it, but when i test again sometimes it gets works sometimes it gets better. Is my approach correct? I dont seem to be losing steps, and my grub screws are tight.
I was also planning to surface my spoile board to have it perfectly flat. I know it is not necessary to level it first since surfaving will make it flat. But it should reduce surfacing time, and i’m annoyed i cant seem to get it to work.
If you’re using the V1E firmware, I’m pretty sure that the bed leveling function is disabled by default. You would have to edit, compile and flash new firmware (not extremely difficult, but not trivial).
Also you shouldn’t enable bed leveling if you’re planning to surface the bed, as it would result in an uneven surface (the compensation from bed leveling would raise and lower the surfacing bit)
More likely I misunderstood. Re-reading your post, it is clear that you were talking about the Z offset (related to squaring), rather than bed leveling. Ignore my previous comments.
I usually physically move one of the endstop mounts since they’re slotted for movement. That gets me close enough to tram the router then resurface and fine tune the tramming again before another resurfacing pass.
