I’ve used my mpcnc to cut large things (on the scale of inches), but it seems to be not so good at small things. I mainly see the problem with small text. I’m attaching a jpg of a test pattern which has shapes and text. The shapes look pretty good - parallel sides, correct size. The text seems a bit squiggly. I went back and adjusted the gantry as described in the assembly documentation - make sure all bearings are touching, etc.
Please look at the output and tell me if you think this is as good as I can hope for, or is something clearly amiss?
I’ll attach the e10 file too if possible.
Thanks.
In estlcam, arc comands are on. I’ll try turning those off.
Speed x,y is 12mm/sec.
z-axis conduit is 14 in. I was planning to also use it as a 3d printer, but that idea is fading.
this is the image with arcs turned off in estlcam. It already looks better. The text is less squiggly.
I’ll also try speed reduction.
I suppose the last option is cutting down the machine height. I suppose go back to the calculator.
I want mill two by N dimensional lumber. What do you think the minimum height would be to support that?
I suppose it depends on the length of my longest bit.
Looks good, at that size it could be your surface, the pen mount, Pen mount tension (should be light try a felt tip), etc. I think it’s pretty good now.
