If this were Mach 3 these exact symptoms would be linked to constant velocity settings. The only way I have been able to combat the issue is to slow down my cut speed...goes from one rounded corner...

Of course any vcarve toolpath can use any v bit. Though you may have to limit depth if the diameter of the v bit is smaller than the widest part of the vectors. The only difference in using different...

Don't know if you are replying to me, Eric, but it sure sounds as if we are both saying the same thing.

Given a proper setup (z zero set, proper bit chosen in tool settings), using vcarve it doesn't matter whether you use a 45deg, 60deg, or 90deg bit. None will go outside the vectors of the letter or...

In support of Brady Watson. I am somewhat amazed to see an implied criticism of Brady's tagline from another valued member of the forum whose contributions I have followed and enjoyed. But Brady's...

I appreciate the responses, guys. Bob Moore hit it on the head. I had been using Artcam for years, but just began using this version recently and this was the first time for vcarving. Missed a...

Machine file generated from Artcam 2018, 1/4" 90deg sharp engraving bit, 17k rpm, 70ipm. Letters about 3/4" high and from standard Times New Roman font. Set for constant velocity. Ragged edge on...

Link to this megabot?

My two cents. I've made thousands of vcarved cedar signs (used to take my smaller CNC to the Christmas fair every year and make signs to order - fun and hectic). Sharp bit, 60-70ipm, 15k, mostly...

And, I've got to give you some strokes. Your willingness to spend the time to spread your expertise is phenomenal. Thank you so much.

Thanks for the reply, Brady. hardware modifications are no problem and I will make them. My secondary question (though not necessarily second in importance) is power/accuracy/speed issue vs what I...

I have an early 2000 PRT with an Ascension box (similar to the 4G). After some years my X and Y pinions are getting visibly worn. I have 20 tooth now and I'm having second thoughts about replacing...

Brian, you are a cross between McGyver and Rube Goldberg. Ingenuity!

We all have to work with what we have I guess. I have a wonderful Inca 10" over and under I've been using for pushing 40 years...it just isn't designed for heavy loads or heavy cuts which makes my...

I dunno, seems to me that most of us reading this forum have CNC machines. Wedges and a larger flat bit will do the same thing. Done it many times to take chain saw marks off of slabs.

One approach I have used successfully is to take a picture (as straight on as possible) with a digital camera, then trace it and scale the tracing to a known measurement on your headliner. Sometimes...

I exclusively use high quality motorcycle chain grease and have for years. Transparent, non messy easy spray on and seems to have a long life of lubrication. I also use it on the plastic to metal...

Marble yes, granite no.

I have some rosewood in that shade and, though wood grain varies in general, purple heart is generally more straight grained. Board on the right has some resemblance to tulipwood. Weight and grain...

Provides a huge amount of extra table space...only I wouldn't have the square footage to even open it up.

Have checked that your rails are equi-distant so that the rollers are not riding up on the rails in spots? You should actually be able to see .015" with a straightedge. Flatten the board, then...

Looks like a PRT Alpha. Still, a great machine.

I can only affirm the above. I often use Doc Crumbly's Rootin Tootin method. I keep old weathered cedar fence boards for rustic house signs, stall signs etc. It is so cool, you will be a believer...

As far as your painter's tape masking, it really has a tendency to fuz up badly and pull off some sections. Save yourself headaches and get some Gerber Mask II or equivalent.

Well, I'm glad for you guys. Never had a piece of padauk that did not come off of the fresh cut kinda red/orange color. Varied after that, with some more like Scott's example and some browner....
