Thanks guys, was just hoping to get some honest feedback from guys really using this machine alot.
My Z axis has play in it when I push on the torch. every time I try to tighten up the bearings it just doesn’t seem to help, that setup is a bit annoying to work with. when I was cycling my Z up and down it was skipping very hard toward bottom of the travel. So I checked the bearings it felt like it was grinding or hanging up. So I cleaned everything, oiled up the lead screw and reset the bearings. Had it ok for a bit. Iv been getting pretty bad bevels and inconsistent cut quality, and way less consumable life. (Iv talked to HYP tech support so many times with the 45 and now my 65 with misfires) but I keep track of how many sheets I cut and when I change consumables and I’m talking drastic difference. Unless I have a bad batch of electrodes ( I buy only OEM hypertherm) See pics of tip and electrode that were fairly new but kept misfiring. I change desiccant 1-2 times a day.
So I decided to remove my machine torch holder, and try the stock holder, which is what I’v used on my old crossfire with machine torch and have had good success. Well with some very new consumables I noticed some strange sounding cuts, bad bevels and then all the sudden blew up tip. I honestly have never ruined a tip like this in almost 2 years of cutting with hypertherms. So I don’t know what really happened. But after that see pic of metal as it gave out. I gave up for the day. I spent more time trying to get Z axis cycling smoothly than I did cutting. So I don’t know if the THC messed up or not with this.
One other thing that has happened is during a misfire sometimes FC senses it and pauses the program and run from here is easy. Other time FC doesn’t sense it and I have to manually pause the cutting and do a run from here.
In the pic of the table you’ll see two 2x2 sheets. On these sheets is actually 4 different files. Each run is about 8 min cut time. I cut 3/16 at 64 amps 130 IMP, pierce delay calls for .2 but I have to bump that up. Plunge rate 50imp and .15 pierce height and .06 cut height per manual.
