Trying again

[Bentup]

Alright, I will try this again. Yesterday my wife and I tried to introduce ourselves as new members of the forum and proud new owners of a Growth Series 4 x 4 table. I have been cutting and welding for 33 years, but the CNC world is new to us. I sent a post yesterday but it went as a private conversation, (sorry to those recipients). My post was asking, after I do the line cut test, how do I use that info to make changes. We cannot see where to adjust cut speed or how to determine what the speed was of the best cut line on the test plate. As I said, we are NEW to this so please bear with us. I am trying to get the machine somewhat dialed in before my wife Susan heads to Reno in June for training. My goal is to have her do 90% of the programming and cutting so our posts may come from either her or myself.
Thanks and have a great day

Welcome! I can't help on the adjustment since I'm using the older version but I can tell you the line speed test runs from 10ipm to 130 ipm. The 10ipm line will have a ton of dross on the backside so you can count from there in 10's. And I always recommend viewing all the torchmate videos on YouTube. Very helpful.

If you have a Hypertherm plasma cutter you generally dont need to use the line speed test, use the values out of the Hypertherm manual. Here is a list of videos that will help you out using your new software:

The way you should be looking at the LINE SPEED TEST is as follows. The first line is 170ipms and drops 10 for every line after ends at 80 and the outside perimeter is set to 100ipms. You will observe the top but the daisy is the backside. What you are looking for is a even cut top to bottom and the least amount of dross. If there is dross you should be able to flick off with your fingernail. Usually there are 3-4 lines that follow this description. So lets say you are cutting 65 amp on 11 ga material. You will notice that 170 too fast and you get around the 110 100 90 looking good. Check with your fingernail ( or other sharp object) to chip the slag. Also remember that the outside is 100. Now thinking that a straight line looks good at 110 but the machine cannot move FULL speed while doing arcs or other detailed cuts. So using this you would set your feed rate to 110-105 for that thickness of material at that amperage that you have set. This will make sure your straight cuts come out good while your internal features would be about 70% of the feed rate for your internal cuts. Since you are about in the same range your interal cuts shoudl come out with little to no dross along with your straight cuts.

FYI... we cover this in the class also.

Are there two line tests? Mine runs from 10-130.

Each system has its own line speed test. the New machines running the Accumove system runs the 170-80 test. The older systems that run the TM3 and TM4 will have the 130-10 test. Personally the 170-80 test is a little more accurate for the common materials because 20-10ipm is a waste.

Ah. Thanks. I agree, 10-20 is useless. I stopped it before it got there. But I feel there is still some usefulness under 80.

Here is a modified .fgc 170-50ipm line speed test. This is a little more useful
