Hello,
Is there someone who designed a drag engraving tool for the MPCNC (Burly)?
I know you can buy a spring loaded engraving bit for the router, but those are expensive. But I’m open to suggestions (I live in The Netherlands).
I ordered some bits from AliEpress:
I was wondering if some designed a spring loaded holder, before I design one myself?
I found this one, but not for the MPCNC specifically:
Tips are welcome…
I only just ordered one of these bits to play with last week so will be watching for suggestions. I’d like to see some way to adjust the spring tension which that holder doesn’t seem to allow for.
Not certain, but I suspect that with the ability to adjust the z axis you won’t need to adjust the spring tension - you can alter the force applied just by shifting the height you run the machine at over the material.
That could work but is a bit hit and miss. I’d think you’d want a means to pre-tension the spring so that the bit contacts the surface with a fixed force. Fudging it into the z height makes it difficult to control the engraving depth.
I agree with superflyguy, I would guess your bed has to be 100% level and it’s not controlabe.
