Trouble finding the file in fusion or trouble uploading to the forum?
Nevermind I see your not doing cad in fusion
trouble uploading to the forum.
If the forum won accept your file typ just change the file ext and that should work. Just let people know what you did so they can change it back.

Looks to me like the notches in your file correspond to the nodes in the post processing. Normally, they should not be this pronounced.
I do all my design in svg and post process in sheetcam from the same svg. I once post processed a font file without checking the amount of nodes, and heard a difference in how the machine ran during the cut I had to stop it and redo everything. Each node, means a pause in the machine however slight, which means a detectable notch in the cut.
The notch is usually very slight, but an experienced eye will catch it.
With your file, I’m guessing your cut speed is already too slow. Post all your settings, equipment, and material.

I agree. The notches are spot on with the nodes. I will post the svg when I have time later today hopefully. I had been under the impression that more nodes was better. The alt-b function in Inkscape will only work about 50% of the time for some reason. I had to do some unexplainable workaround to get this thing into one unified file. It left the image vectored but slightly jagged up close. I think it ended up placing a ton of nodes in the lettering and I noticed weird chunky cuts on some of the larger sweeping lines. You could here the matching bouncing off the nodes. Do you ever run into Inkscape glitches? Sometimes Inkscape will repeatedly crash and functions won’t work. It’s quite frustrating. I am using a brand new powerful Lenovo. Dedicated to fusion and Inkscape.
Check out the 24 minute Mark of this video it describes an easy way to share your Fusion file information.
Also this forum topic covers exporting and posting a f3d file to The Forum.

Yes, Inkscape has a lot of features, but it’s not polished software. It can’t handle giant drawings.
If you like Inkscape and don’t want to pay a subscription for software. Use Affinity Designer. When you set it up with the grid and rulers and snapping, it’s CAD accurate and does artistic curves and shape subtraction very smooth.
But, what are your settings and machine? Overall the cut doesn’t look right.

i posted the file above. some of the things i have been noticing. and things i am tring to figure out.
- when i cut at higher speeds i get lower quality cuts. i had thought that higher speeds could make the cuts smoother.
- when i am cutting long radius’ sometimes the radius cuts seem to pause or (glitch and the motors on the table make crazy robot frequency noises.
3.sometimes my x axis will bind up when i first start my table when i am running at 400ipm. i am not sure if it due to the chipping paint on the gantry or something else. i meticulously squared everything yesterday. - x axis paint chipping is causeing some vibration is causing i think it is a normal amount. i placed vinly tape under the bearings and it ran much better. let me know if this is normal stuff.
- im sure i overthink alot, its just hard to figure out how to get the best cuts when first staring out. any info is greatly appreciated.
@TinWhisperer i posted the file above if you have a chance to check it out. thanks!
@brownfox
so its been a while since i did this cut, i got caught up with work and im back at it. i was running 45amps
168 ipm
100 psi
standard cut consumables.
i have since switched to the fine cut consumables. this has helped a bit with quality.
i also started cutting slower, around 50 ipm and lower pressure. i just purchased an air dryer so i should have the quality control good on my side . some of the issues are ironed out but some glitchy lettering is still persisting. i was really hoping to be able to cut designs at higher speeds. i will cut another copy of the file i am speaking of and see what improvements i have made. i will also record all settings and post.
so the affinity designer should be a better fit for me? i am looking to do some pretty large intricate cuts in the future.
thank you all for the help.
I was just reading through this and I did not see where you said what thickness your material is.
One I will say is when your trouble shooting making a large change in your settinging and changing more than one thing at a time is bad idea.
You were at 168 ipm and went to 50? thats a huge change.
Why dont you share the following:
What cutter are you using?
Material thickness?
do you have your air figured out? If so share your set up. Compressor size, what do you have in place to aid with drying your air?
Are you sure the air pressure on the gauge on the cutter is steady while cutting?
Have you gotten good cuts in the past?
If so were they artsy pieces like your trying to cut now?
Forget higher speeds for now and concentrate on good cuts, then you can chase faster.
When you first get in a race car, you don’t start out going fast till you learn everything else.

looks like 270 ipm for 14ga with the standard cartridge cut height of .125
& 220 ipm for 14ga with the finecut cartridge on high speed cut height of .14

check out this live stream but the drawing is not that too bad.
I made a few change in the work flow and a couple in the 2d profile settings .
For some reason the sound is muted…

hypertherm 65 sync w/ 30-45 fine cut pod
16 guage steel
80 gal ingersol rand dual stage compressor
harbor freight air dryer.
smc dual filter off of the compressor
motor guard toilet paper roll.
i set my pressure at my main reg/filter then it hits the smc regulator filter then air dryer, then it goes to toilet paper roll, then small stock hypertherm filter then i tee into my gauge, this guage checks for pressure differential. i always have totally smooth consistant pressure at both gauge sets. i have gotten one cut that is about 90% quality. the good cut, i made sure to upload and then ran pretty heavy smoothing and it helped.
the drop from 168 to 50 was me checking to see if mabye i had overtightened the rails and the motors couldnt keep up with the speeds.
thanks!
thank you for taking time to do that. i watched the video. im making some tweaks now.

did you try the file Tin touched up?

not sure how much difference it will make but your refrigerated drier should be right off the compressor.
is this a dessicant type?

no dessicant, i havent gotten to the touched up one yet. i should be able to tomorrow. the air dryer is about 8’ away from the compressor due to my tiny shop.
ill give an update soon!
cheers!
May want to add an aftercooler to the compressor. If you’re supplying the air dryer that soon in your line, it’s probably not working as efficiently as it could. I believe they recommend a decent amount of line separating it from the compressor.
I have some hoses that would probably fit right on your compressor to pipe the aftercooler super easy without having to run any copper pipe or anything. My compressor is an IR 60 gal so I’m pretty sure the pump and tank fittings are the same.
I need to start an affinity twitch stream. I have a way that I simulate the kerf width while I’m designing to make sure everything fits before post processing.
Also, the sync cartridges are supposed to have a crazy small kerf. I cut with hypertherm fine cuts on 16 gauge with my 45xp with book specs.
However, I also have a rule set in sheetcam that I tweaked until I got optimal results every time.
So this is a great representation of what is causing the main issue. When cutting radius’ when the machine travels in one direction it is butter smooth. When traveling in the opposite direction it glitches hard. The machine is jogging great and all axis are tight no slop. This is getting pretty crappy. Here is a photo showing the three radius cutouts and a video of the malfunction.
youtube video of glitch
Video did not work for me. So straight line cuts are fine?
yeah it will run one side of the radius smooth as butter, when it gets to the opposite side it glitches and does these micro pauses. i wish i could get the video to work.
i posted a link to the video above on youtube.
