Codes only in Mach 3 problem need firecontrol code

These things are much easier to diagnose if you can copy and paste some of the code from your cut files. Open a file with Notepad and copy and paste the code. A smaller cut file will allow you to post the whole code.

I’m not sure if the forum or .tap files to be uploaded here, but that would work also.

will this help

Yeah. That helps. That code is not even close to what is needed for Firecontrol. What are you using to create the code? Fusion or Sheetcam? Either way, you need to use the Firecontrol v1.6 post processor.

fusion 360

Ok. I don’t use Fusion, so I can’t help you with how to install the proper post processor. One of the fusion users, like @TinWhisperer can probably help you with that.

I just got this set up and have no clue what I am doing. I did cut one thing from the share files but nothing else works. I have tried every set up video I can find.

Have a look at the link in this thread. It’s for the mr1, but the process is the same for installing the Firecontrol v1.6 post processor.


@mwcpd131 I missed a PM from you about a week ago.

How are you doing with this issue?

Were you able to install the post processor?

Yes sir I was able to get the post processor working the only issue I’m having now is the THC when I have it on it starts cutting and as it goes it slowly raises up if I turn it off it cuts everything just fine I still have to learn my Heights and speeds to get everything correctly. I have not had time to research the THC to find out why it’s doing that if you have any information on it that would help greatly thank you

It’s your IHS triggering early?

Could you post a picture of how your torch is mounted on your pro.

Sometimes there might be not enough clearance on the z axis depending on how you mounted the torch.

I’m Canadian so American phone calls are costly for me but if you want to talk on discord I’ll be back from work at 3:00 p.m. Pacific standard time today.

I would check the up and down motion of your z-axis and make sure it’s not triggering the IHS at the wrong time.

You can tell if the IHS switch is closed by looking to the bottom of fire control there is a box that will turn green once the IHS switch is closed. You can trigger this yourself by manually pushing up on the torch softly the same way the torch would push against the metal when touching off during the program.

It does give an error code that says the torch started to move before it fired sometimes. I will get some pics.

I have a video but it the forum will not allow that to upload. thank you again for your time.

move down the torch.

DO NOT clamp on the consumable retainer.

Only clamp on the barrel of the torch.

I think z axis travel is an issue here.


Torch raising is a classic symptom of interference. This is usually from running firecontrol off a computer that’s plugged in with a grounded plug in an outlet. If it’s a laptop run it off battery.

The easiest way to tell why this is happening is to look at the live voltage readout while cutting. Depending on your cutter and the material thickness, you should probably be in the neighborhood of 120 v. if your live voltage far below that, un plug the the laptop and see if it changes. If it doesn’t change, confirm your VIM module is wired correctly into your cutter.

Thank You I will try that this weekend.

so don’t clamp it at the bottom where I have the red part attached? clamp it on the larger part?

Correct. You could invert the torch mount and clamp up on the barrel without losing any z travel. Most machine torches have an obvious seam/joint where the barrel ends. You don’t want to clamp below that joint as you could constrict the plunger which needs to be able to move freely.
