Hi all

I cut some 1" HDU letters on Saturday and they looked great. Well, that is until today when I took a closer look at them. There are several "u" and "n" in the copy. Since I had to drill 1/8" holes for mounting pins I added them then cloned the letter several times after adding the pin locations. it was this letter that came out strange plus a larger "r" on a different line of copy and larger size. i sent the file to support and they said that the file looks fine. i tried to attach the actual cut file but got an invalid file type message. if someone can remind me how to upload that file type I will.

i got the original file as an EPS from another sign maker, imported it into Aspire and made my tool paths. On the highest resolution the preview was great. The HDU was 15lb, 1" thick. The bit is an Amana 46292 and was never used before this job. I cut the letters at 5 ips and a pass depth of 1/8". My machine is a 6' x 10' prs-alpha (2020 vintage - with less than 100 hours on it - probably closer to 50*) with a vacuum hold down. Beause of issues with the ATC I ran the file as a manual system. it was only the u/n and that "r". Everything else was perfect.

*Yes I need to use it more but am always busy with the main portion of my sign business. Also, it seems that I'm always having some issue or other with this machine. And yes, i previously paid for a shopbot tech to come out and spend two days here to make sure it was all set up correctly, etc. But that's a rant for another time.

Support wanted me to see how much (if any) play I have on the x/y gantry but if the machine had slop then other letters would have been bad as well - correct?? All the copies of the u/n were exactly the same plus the r had the same kind of issue. Suggestions? Before letting loose on an expensive sheet of HDU i did a test cut with an "o" and a period. That I cut at 10 ips (not intentionally - I was playing with different speeds and never dialed it back to 5 ips) and they were perfect.

And yes I am being picky but this sort of thing shouldn't happen at all. I'll sand those letters slightly and my customer will never notice them.

Thanks for any input.
