Hello all. First time poster, about a month long (20 work days) x-carve user, and daily forum reader.
Have finally reached the point of “wtf, please help.”
So the details.
-1000mm Machine - DeWalt 611
-Attempting to cut 1/4 inch Lexan
-Speeds(currently): DeWalt at top speed - Feed Rate: 40in/min - Plunge Rate: 9in/min - Depth per Pass: .0575
-Bit: 1/8in dual flute straight Onsrud
Attempts to rectify:
Several test cuts, using many different methods described within these forums. Many bit changes, based on recommended bits in this forum. Speed changes, etc. Belt tension, potentiometer adjustments, usb plug changes, leveling, re-leveling, vacuum table, no vacuum table. Eccentric nut adjustments, belt alignments, sprocket alignments, constant waste removal, rail cleaning, etc. Pretty much what im trying to say is ive tried probably every suggestion in these forums when it comes to cutting acrylic, plexiglass, plastics, etc. I have all the recommended bits, and have attempted all the recommended speeds.
Here is the problem:
SVG paths are created using Gimp and Inkscape and then imported into Easel. The first pass always seems to be perfect. The second pass however, almost every time, veers off course. Ill stop the cut, and send it home, but it never goes back home 100%.
Reset home, lower speed, reduce depth, etc, same scenario.
As of today, i had my first perfect cut. This was, i assumed, the results of tuning the potentiometers on friday. I tuned them, tensioned the belts, checked my nuts, ran my cut. Perfect. Removed stock, added new stock, first pass perfect, second pass, right back to where i was a week ago.
So I am here now, asking for some assistance, or any suggestions of something i maybe have not yet tried, or some guru to say, “hey, do this”.
Now i understand that this machine takes a lot of fine tuning to get it working 100% of the time, and even them it will still require attention to maintain that 100% capacity. I have just spent 8 hours of work day attempting to tune this fish, to still only have the same issues reappear.
If I am missing any details in this post, please let me know. I will be attaching pictures, but for some reason right now they not coming through my email properly.
Thanks in advance for any assistance. Any clarification needed, please just ask.
