Abnormal cutting quality with hypertherm 105 sync
Hi
I am using a 105A cartridge from hypertherm 105 sync. The cut quality is not normal. When the cartridge is abnormal, it is only used 50 times. The ink cartridges were completely fine the first time they were used. This situation has never appeared on the 65A and 45A ink cartridges, what is the reason?

Re: Abnormal cutting quality with hypertherm 105 sync
I agree with Tom. There have been many reported issues with the new Sync cutters and perhaps you have discovered another one of them. If you are only getting 50 cuts from a $50 cartridge, then something most definitely seems wrong. I would also advise you to contact Hypertherm tech support directly, and perhaps send them your cartridge for evaluation.
What is the thickness of the material you are cutting? It looks to be around 1/4" thick from the photos. Is there a reason you are using 105 amps for cutting material this thin?

Re: Abnormal cutting quality with hypertherm 105 sync
Seriously. You are only supposed to cut up to 3/4" with a 105 Sync cartridge? I cut 3/4" & 1" with my 65 non-sync. That's disappointing.

Re: Abnormal cutting quality with hypertherm 105 sync
I have looked at the manual for the Sync 65/85/105 and can't find any cut charts. They refer to them in the screen shot I posted above. I am wondering how you are supposed to set your cut height, pierce height, pierce delay, cut speed, etc. with no mechanized cut charts. Are you supposed to use the same settings as for the non-sync models? Sure glad I don't have one of the sync cutters. My Powermax 85 (non-sync) is rated to cut 1 1/4", and will probably cut a bit thicker than that. Not that I need it for my usual projects.
The photos from the op look like maybe 1/4" thick. I can't really tell and he has not been back to tell us. If he is cutting 1/4" at 105A then according to the chart above, his cuts will not be optimum and his consumables may wear out quicker.
We really need more information here.

Re: Abnormal cutting quality with hypertherm 105 sync
1) The only issue I've heard of with the SYNC machines has been with ohmic sensing and fine cut.
2) The chart posted shows that optimal cuts on 105 is up to 3/4. Beyond that quality OR speed is reduced. Yeah, speed is reduced just like on your 65.
3) David, the SYNC cut charts are in a separate file from the manuals. Everything is there in that file.
To the OP - The S-shaped striations point to cutting too fast. I don't know what thickness that is but you should double check the charts and make sure your travel speed and heights are both set correctly and maintained correctly by your table.
Pierce height is 0.25", Cut height is 0.125"
1/4 is a 0.5 second pierce delay and cut speed of 156 ipm
3/8 is a 0.8 second pierce delay and cut speed of 94 ipm
If you're on SI/Metric units then those are available in the cut charts of course.

Re: Abnormal cutting quality with hypertherm 105 sync
Thank you all for the replies
I also inquired with the local technicians at the same time, I haven't received a reply yet, this is an 8mm steel plate, because the customer does not require a beautiful verticality, I choose 105A cartridge cutting with less slag, but in fact The same situation also occurs in the 3/4 steel plate. Everything is cut according to the parameter table. The corrugation is the problem of the cutting table itself. After a while, it will be replaced by a plasma cutting table with higher moving stability.
This is 3/4 steel plate This is 1/2 steel plate

Re: Abnormal cutting quality with hypertherm 105 sync
Those edges on the thicker plates look pretty good to me. According to the cut quality chart I posted above, your 8mm (5/16") plate should give a good quality cut with the 105 amp cartridge if the proper cutting specs are used from the mechanized cut charts. So it is unclear to me why your cartridge wore out so soon. Perhaps it was defective and you can get Hypertherm to replace it.

Re: Abnormal cutting quality with hypertherm 105 sync
I would be suspect of the stability causing issues in the corners due to XY control and how well it is maintaining cut height. It might be necessary to manipulate the cut paths to get this to provide acceptable results. (For instance cutting a square by cutting 2 parallel lines and then 2 intersecting parallel lines to drop the square out.) Not ideal and way too many pierces. Maybe dog boning the corner might help. (Loop the cut path past the corner and back around in a circle to intersect and cut the next side.

Re: Abnormal cutting quality with hypertherm 105 sync
But the strange thing is that the next time I continue to use the 105A cartridge, the problem of poor paper cutting disappears. It appears to have appeared after more than 30 consecutive decoupages. Sorry, I didn't cut too much 105A, I can only guess, I bought two 105A ink cartridges, both are the same, I think it may not be the ink cartridge factor, I forgot to write, my air compressor discharge volume is 750L/min, pressure 8kg, using freeze dryeradbuch wrote: ↑Fri Oct 28, 2022 1:26 am Those edges on the thicker plates look pretty good to me.

I'm getting the same bad cut quality from my 105 Sync, no matter what I do it doesn't change.

Re: Abnormal cutting quality with hypertherm 105 sync
Before you blame the cartridge verify cut height, pierce height and air moisture. A good refridgerated dryer can only drop moisture maybe 30%. We have lots of customers with very very good 105amp results. But they do not pierce or cut at the same old 105...so differebt volt preset, higher pierce and higher initial cut height
