Hi. I’m working on carving a sign, and it seems the speed is pretty slow and jittery. Not sure what is effecting it. I have the feed rate at 50 mm/s (up from 15 mm/s that was initially recommended). Thing is I have already run this project before and I don’t recall it being so slow the first time. But then again I was pretty excited it was even working. Regular engraving paths seem to be fine (speed wise) Is it normal to be slow when carving? Video attached may be poor, I have to convert from iPhone to Windows to shrink it down). Ignore the duct tape nightmare that is my dust baffle. FWIW, I’m running on Rambo 1.4 with a Raspberry Pi Zero W feeding it. The artwork comes from a traced bitmap in Inkscape maybe not the smoothest boundries.
On a related note. I am trying to cut painted MDF in this case. As you can see I am getting paint folding back on the edges. I am not sure if it’s relate, but I noticed if I rerun the same job, where it re-cuts it gets smoother some (sort of a finishing pass). How to I get carve to make a finishing pass on purpose? I tried setting the allowance, but it just runs the same regardless. Meaning it does not appear to be going back to clean up. The paint folding may be because it is not fully cured too. It was just painted today.
Thanks in advance for any advice you might have about either issue.
